It's just that simple. This lightened flywheel weighs 8 lbs compared to the 20+ lbs stock Honda flywheel. Although a flywheel doesn't add HP or torque it will make your car accelerate faster. With a lightened flywheel your RPMs spin up faster as your car builds momentum. This can definitely be noticed from a dead stop. You will feel a gain in acceleration up to third gear, when the momentum of your car and the benefits of having a lighter flywheel cease to exist. A lot of people have griped that since your RPMs rise so quickly they will drop off between shifts just as quickly. Personally, I have not experienced this problem and although it is a nice theory, it is probably just that - a theory. To be fair I also have the Stage 1+ clutch and a short shifter, which combined doesn't give much time to drop off RPMs anyway. You may also hear that your car will idle rougher since the car is built to be in harmony with a much heavier stock flywheel. This does have some truth to it. If noone ever told you this little fact you probably wouldn't notice it. I can sometimes detect the car idling a little, and I mean a little, rougher but nothing that I would really care about. It could also be a number of things such as my intake, headers, or exhaust.So why did I go with this flywheel? I went with the UR ultra-light flywheel because I wanted a clutch that came with a matching flywheel package. Most aftermarket clutch makers don't make a flywheel, so you will have to go with another manufacturer for the flywheel.Under driven pulleys info The traditional method of underdrive pulleys focus on the major reduction of accessory draw, which has historically caused many problems in electrical charging and cooling. However, unlike traditional underdrive pulleys, Unorthodox Racing has concentrated on rotational weight reduction rather than severe underdriving to gain horsepower, eliminating electrical and cooling problems. In fact, Unorthodox Racing claims that 70-75% of the power generated from changing the pulleys is from significant weight reduction, or in this application-approximately 5 lbs. On a stock car, this translated into a 3 tenths gains and 2 mph in the quarter-mile (test figures by Impo Performance).Potentially any accessory pulley (alternator, air pump, power steering, and water pump) may be underdriven by changing the size of the pulley's diameter. In this case, underdriving would increase the diameter size of the accessory pulleys so that the pulley's rotations are decreased, spinning 20% less than before. In addition to the underdriving of the accessory pulleys, the crank pulley is actually decreased in diameter by 8% thereby further increasing weight loss.The concept of "underdriving" is quite simple to understand, however the engineering and precision is quite complicated. Shawn Baumgartner, President/Owner of Unorthodox, claims that the engineering for the VR6 is nothing less than a master piece, as a perfect blend of balance in weight and accessory reduction have been achieved. Each pulley is made of superior quality billet aluminum and made with high tech machining tools that ensure a flawless pulley.The Unorthodox Pulleys are rather unique in comparison to any other modification to the VR6. It is unique in the sense that, the Unorthodox pulleys will actually make a greater difference when additional modifications are made since every part of horsepower growth requires the pulleys to spin faster and freer.Before the installation occurred, the car was dynoed on a Mustang Dynamometer for a baseline figure. Once the pulleys were installed the car was re-tested on the same Mustang Dynamometer at Advanced Motor Solutions. *According to the manufacturer, the dyno pulls should have been made on a separate day from installation to ensure that the computer has properly adapted to the pulleys.In this same day test, the Unorthodox Pulleys yielded a peak gain of 2.5 horsepower and 7 ft lbs. of torque. But temporarily ignore the peak gains, as they hardly reflect the whole picture. An additional 4 horses were found at the mid and upper mid RPMS along with a gain of 2-7 foot pounds of torque throughout the entire RPM band.The bottom line is, the Unorthodox Racing pulleys rank a "10" in quality and in performance. They are easily installed/removed and the outcome is great. Improved mileage, better throttle reponse, and excellent power gains makes this $359 dollar mod a winner in every aspect.Additional NotesAn average of 3-4 mpg increaseImproved throttle responseNo problems in chargingNo increase in oil or water temperaturesHere are some FAQ about these partsThe Facts About Unorthodox Racing Aluminum Flywheels 1) "What are Unorthodox Racing Ultra L aluminum flywheels?"Unorthodox Racing aluminum flywheels are a direct replacement for the stock cast iron flywheel. They are made from aircraft grade 6061-T6 billet aluminum. We include a blanchard ground or stock type finish (surface hardening) steel insert for the clutch contact surface. The insert is mounted with only the highest strength bolts available in a pattern of 8 or more bolts depending on the steel insert size. A new factory starter ring gear is pressed onto the outer diameter of the flywheel. The ring gear is also bolted to assure it will not move. The steel insert and the starter ring gear can be replaced by the owner without having to send the flywheel back to us.2) "How does an Unorthodox Racing Ultra L aluminum flywheel give me more power?"Weight loss is the most critical factor in HP production. Each 1 lb. of mass taken off the crank/eccentric shaft is worth approximately 2.7HP, the figure increases substantially with forced induction, nitrous, VTEC and increased RPM's. Performance gains of between 30-40% have been realized for each flywheel application/model without sacrificing safety or durability. This principle allows us to achieve the most HP gain without causing any adverse effects in the general drive-ability of the vehicle. If a flywheel is made too light it will cause engine stalling and low rpm drive-ability problems. If a flywheel is made to heavy it will not maximize HP gain.3) "Will an Unorthodox Racing Ultra L aluminum flywheel cause driveability problems?"The design of each flywheel is tailored to maintain normal driveability that you've come to expect from your daily driver or street/strip car. These flywheels make dramatic improvements in throttle response and overall acceleration. The reduction of weight will allow you take full command your engines output potential instead of wasting the power trying to turn the heavy mass of the stock flywheel. The weight reduction will also help to reduce stress on the engine and drivetrain components by reducing the shock that the extra weight from the stock flywheel exerts on both systems.4) "Is the Unorthodox Racing Ultra L aluminum flywheel balanced?"Each flywheel is CAD (computer aided design) designed to standards that exceed original equipment flywheel. We use only the highest quality aluminum, Alcoa 6061-T6 billet. This material is extremely consistent and ensures that each flywheel that comes off our CNC machines is perfectly balanced. We use only the highest grade materials for the replaceable steel insert, which assure proper balance. We only use new factory starter ring gears, pressing them onto the flywheel and bolting them in place to assure that the b
alance set on our machines is maintained throughout the life of the product. These processes and high quality materials ensure the peak performance and long term durability of our flywheels.5) "Will the Unorthodox Racing Ultra L aluminum flywheel warp or distort over time?"We have spent many hours designing and testing each model, both on the street and on the track, to ensure that each flywheel provides maximum performance without compromising long-term durability. We specifically tailor the flywheel thickness to each application to ensure that warpage will not occur. The 6061-T6 aluminum has heat dissapation qualities far in excess of any steel or cast iron unit. The aluminum design is also much safer than lightening the stock cast iron flywheel. Stock cast iron flywheels must be excessively lightened to compare with our aluminum flywheel weight, this excessive lightening poses a severe explosion harzard with the stock cast iron flywheel.6) "Isn't my stock flywheel a balancer, or vibrational damper?"The factory flywheels on today's late model sport compact cars (from 1986 to Present and sometimes even earlier depending on the vehicle) can sometimes serve two functions. First and most importantly they are designed to make a stock motor have consistant drive-ability at all rpm?s. The idea is to use centrifical force, by making the flywheel heavy, which helps the motor maintain its speed or momentum. This theory was more applicable when engines used carburetors and vacuum controlled ignition. Late model cars have fast computers that take full advantage of reduction in engine rotating weight. The second function designed into some factory flywheels is for reduction of transmission noise. This shows the factory fanaticism about making the car quiet for the occupants (i.e. the use of resonators in the intake to quiet intake noise, all aftermarket intakes eliminate these resonators), it has nothing to do with engine function or longevity. Our flywheels are significantly lighter than their OEM counterparts (anywhere from 10 to 25 lbs.). This weight loss dramatically reduces the stress exerted upon the rotating assembly by the excessively heavy factory flywheel. Our flywheels are so well balanced that when owners call us about how happy they are with the product they always mention their motor feeling smoother.7) "Will the flywheel void my factory warrantee?"Actually the answer is fairly complex. Automobile manufacturers state if a specific component is not designed by them or an OEM supplier specifically for use on your vehicle from the factory, then the component voids your warrantee. This area has been a hotbed of controversy for years. SEMA has been working feverishly to protect owner's rights on this issue because many aftermarket products are viable replacements if not better in design and function than the factory component. UNORTHODOX RACING aluminum flywheels are one of many such products, from air intakes to computer chips to exhaust systems. The simple truth is that most dealers are looking for any excuse to avoid working on vehicles modified with aftermarket performance parts. The key is that owners must be aware that these situations can arise and this is clearly stated in the back of their owner?s manual that non-OEM products void the manufacturer warrantee. This, not surprisingly, includes performance parts designed by car manufacturers (i.e. Ford Motorsports, TRD, Mazda Competition and GM Performance to name a few).8) "Are the aluminum flywheels hard to install?"Most of our aluminum flywheel can be installed in under 3 hours by a transmission specialist. It is important that you go to a certified professional to install this part as installation mistakes are quite costly. A new pilot bearing should be installed with any flywheel change. Some of our flywheels do include pilot bearings. New flywheel and pressure plate bolts should also be installed with any flywheel change.9) "Do I have to change my clutch when the aluminum flywheel is installed?"The clutch should be changed when you install an aluminum flywheel. There is almost no additional labor for installing a new clutch because the clutch is bolted to the flywheel and it involves the same amount of labor anyway. While you can use any stock or aftermarket clutch, we recommend our heavy duty clutches which are available for almost any application. Stage 1 is for mild mods, street and very little track use. Our Stage 1+ is for medium to heavy mods, street and track use. Our stage 2 (single disc) and stage 3 (twin disc) clutches are available in a strapped pressure plate for street and pinned pressure plate for racing only. Stage 2 and 3 clutches are for heavy to wild modifications.10) "Will the aluminum flywheel cause my engine to have premature bearing wear?"This is a fear many prospective owners have and it is a valid concern since we are dealing directly with the rotating assembly. Fortunately this is not a problem. It is a fear with no basis in fact when it comes to our aluminum flywheel. The design and balance of our aluminum flywheels are significantly better than the factory flywheels. Our aluminum flywheel design actually increases longevity of the rotating assembly of your engine. The aluminum flywheels relieve unnecessary engine stresses inflicted upon your engine by the larger and significantly heavier stock flywheel, which has more harmful leverage on the crank/eccentric shaftContinued on next post

Lightened Underdrive Pulleys1) "What are Unorthodox Racing lightened underdrive pulleys?"Unorthodox Racing lightened underdrive pulleys come in four versions. The first version is our Ultra S, which is the lightened underdrive crank pulley. It drives all the accessories that came factory with the car. The Ultra S lightened underdrive crank pulley is smaller in diameter and 60-90% lighter than the OEM crank pulley it replaces. All of the underdriving is done from the Ultra S lightened underdrive crank pulley.The second version is the Ultra R lightened underdrive crank pulley, which is also a crank pulley. It drives only the alternator or alternator and water pump depending on the application. It was developed for the racer and for engine swaps. It has the same percentage of underdriving as the Ultra S version but is 90-95% lighter than the OEM crank pulley it replaces.The third version is the Ultra SS lightened underdrive pulley set. The Ultra SS lightened underdrive pulley kit comes with the Ultra S crank pulley and our Ultra A accessory pulleys for the alternator, power steering, and water pump (depending on your application). The Ultra SS lightened underdrive pulley kit has no more underdrive than the Ultra S lightened underdrive crank pulley, meaning you will have no electrical, cooling, or power steering problems. The a/c is still driven from the crank pulley in the Ultra SS kits so don’t think it has to be removed or can’t be used.The fourth version is the Ultra A accessory pulleys. The Ultra A accessory pulleys are what make up our Ultra SS kits, but more importantly they are available individually for owners who have already purchased our Ultra S lightened underdrive crank pulley and now want the Ultra A accessory pulleys to finish their pulley set.Unorthodox Racing lightened pulleys underdrive the accessories by changing the diameter of the crank/eccentric shaft (main) pulley. We underdrive the accessories with the Ultra S crank pulley in order to maximize the weight loss versus the OEM crank pulley. Underdriving also allows us to reduce the drain of each of the accessories off the crankshaft.2) "How do Unorthodox Racing pulleys give me more power?"Weight loss is the most critical factor in HP production, each lb. of mass taken off the crank/eccentric shaft is worth approximately 2.7 HP and the figure increases with forced induction, nitrous, VTEC and increased RPM's. Only 15-20% of the gains seen from our pulleys comes from the underdriving. We achieve the maximum gain for each application/model by the singular use or combination of reduced diameter ("underdriving") and weight loss versus the OEM crank pulley/s. This principle allows us to maximize the HP gain without causing any adverse effects in the general function of the vehicle.The diameter of each of our crank pulleys is reduced specifically (from 20-30%) to the vehicles accessory needs. In other words we maintain all accessory minimums: air conditioning efficiency, power steering feel, and voltage (minimum allowable voltage 12v) even at idle with everything electrical on in the car. There are no adverse effects from the use of our pulleys whether Ultra S, Ultra R, or Ultra SS pulley sets are used. Bolt them on and forget about them, then just follow your vehicles normal maintenance schedule. 3) "Isn't my stock crank/eccentric pulley a balancer, harmonic/torsional, or vibrational damper?"A common misconception is that factory crank pulleys on certain vehicles are harmonic dampers. The fact is, on todays late model cars the factory crank pulley is designed to reduce NVH (noise / vibration / harshness), which does not affect crankshaft or bearing life. These are noises and vibrations from the engine compartment that may travel into the cabin of the vehicle when the engine is running and the stock crank pulley is used to reduce NVH for the occupants (similar to the use of resonators in the intake to quiet intake noise). We do not manufacture crank pulleys that replace or eliminate a damper in applications where the factory crank pulley is an actual harmonic damper (such as 90 degree V engines).Our pulleys are lightweight, CNC-machined 6061-T6 aluminum and are by design "0" balanced. Because of this, owners have called to tell us how much smoother their engine feels after installing our pulleys. Unorthodox Racing has been manufacturing and selling pulleys for over 5 years without a single engine failure due to the replacement of the stock crank pulley. This is testament to the quality and reliability of our products.Owners who have engines that use balance shafts must understand that if they eliminate their balance shafts their engines must be balanced and blueprinted if they expect to have no long-term engine problems with or without the use of our crank pulleys. This balance shaft elimination is rare and only happens on a few models that are modified for racing only (Eclipse/Talon/Laser/Galant VR4/Conquest TSI/Starion just to name a few).4) "Will the underdrive pulleys cause my engine to have premature bearing wear ?"This is a fear many prospective owners have and it is a valid concern since we are dealing directly with the rotating assembly. It is, however, a fear with no basis in fact. The fact is that our pulleys have the opposite effect on engine bearings. The combination of tight tolerances, quality control, perfect balance, and dramatic weight loss versus the stock pulleys reduces the stress on your engine extends the total service life you can expect from your engine. Engine bearing problems are purely associated to poor engine maintenance, use of heavier than factory recommended oils, improper engine building practices which includes poor balancing, excessively revving engines when they are cold, and owners expecting their factory oil pumps to handle engine HP outputs 2-3 times over stock HP levels.5) "Are the underdrive crank pulleys hard to install ?"In most cases if you can change your oil or do a tune-up, then you can install one of our crank pulleys. Each one of our underdrive pulleys comes with model specific installation instructions that cover everything from jacking up the car to the factory torque specification on the mounting hardware.6) "Do I have to change my belts when I install the pulley ?"Yes, the belt sizes change when you install the underdrive crank pulleys. Because the pulleys are 15-20% smaller than the factory pulleys, the factory belt lengths are 2-3% longer than necessary. The installation instructions we supply include the part numbers for the belts we have found most consistent for each model of pulley. In addition, belt sizing is available on our website. The belts you will need are available from your local auto store. We would appreciate any information on belt sizing for applications that do not include specific belt sizes as it allows us to accumulate additional sizing to compare with other data we have compiled. We recommend the use of Gates belts. It is important that the belts are slightly over tightened when they are first installed as this accommodates for natural belt stretch. We do not supply the belts with our kits for two reasons. First, we don't feel that our clients should have to pay NY prices (Long Island has the highest pricing in the country) for their belts, as most of you will be able to find the belts for a lower price in your area. Second if an owner happens to have a rare car that needs a different belt than the ones we have found to work, they've paid for a belt that does not work. Belt sizing can vary due to the oem manufacturers production cycle, this is due to the use of different accessories, different brackets or a combination of both.7) “Will the pulleys void my factory warrantee?”Actually the answer is fairly complex. Automobile manufacturers state that if a specific component is not designed by them or an OEM supplier specifically for use on your vehicle from the factory, then the component voids your warrantee. This area has been a hotbed of controversy for years. SEMA has been worki
ng feverishly to protect owner’s rights on this issue because many aftermarket products are viable replacements if not better in design and function than the factory component.UNORTHODOX RACING pulleys are one of many such products, from air intakes to computer chips to exhaust systems. The simple truth is that most dealers are looking for any excuse to avoid working on vehicles modified with aftermarket performance parts.Now if a product is CARB compliant it is more difficult for dealers to reject warrantee claims, but this is only one side of the equation. The parts still need to be deemed as replacement parts. We, as well as many other manufacturers, are in the process of applying for and receiving E.O. numbers which gives us an exemption for emissions compliance with our products.The key is that owners must be aware that these situations can arise and this is clearly stated in the back of their owner’s manual that non-OEM products void the manufacturer warrantee. This not surprisingly includes performance parts designed by the car manufacturers (i.e. Ford Motorsports, TRD, Mazda Competition and GM Performance to name a few).8) "Does the anodized coating wear away ?"The anodizing on our street (ULTRA S) and our street set (ULTRA SS) pulleys is for long term protection of the aluminum from the elements of weather. The anodizing will eventually wear away on the belt sections where the belts ride on the pulleys, but this is inconsequential as the rest of the pulleys are still protected.9) "Can the anodizing cause the belts to slip ?"Actually the anodizing will help to eliminate belt slippage. But even without the anodizing, as our Ultra R race pulleys have no anodizing, the belts have the same grip that they do with the stock pulleys.10) " Is there any long term maintenance required with the pulleys ?"The only maintenance required is to check and replace the accessory belts at the manufacturers specified intervals. Other than this you basically bolt on our pulleys and forget about them.11) "Will my engine RPM's change ?"The pulleys have nothing to do with the transmission and the gear ratios. The pulleys only change the speed of the accessories and nothing else. The transmission and the differential, as well as tire size, control engine RPM at any given speed.12) "Can I use the underdrive pulleys if I have a high wattage stereo system ?"The Ultra A, R, S & SS pulleys still allow stereo systems of up to approximately 400 watts RMS. If the stereo system in question is above the amount then the owner has two options. One we can make a custom alternator pulley, which will be smaller in diameter and will increase the voltage output, or they can purchase capacitors. Capacitors are the better choice as they store the power the amps need for peak draw of the amplifiers, these units allow the owners to achieve the cleanest and most powerful sound with no loss of voltage even with underdrive pulleys installed. Another good option would be to install a second battery for the stereo.Our 1988 Project RX-7 has a 700 watt RMS stereo and our 1993 Project Supra has a 500 watt RMS stereo and they both have no voltage drop problems with our underdrive pulleys.Continued on next post

The Facts About Unorthodox Racing Clutches1) "What are Unorthodox Racing Ultra G stage 1 or stage 2 (formerly stage 1+) clutches?"Each Unorthodox Racing Ultra G clutch kit is a direct replacement for the stock clutch and will work with the stock flywheel or any aftermarket flywheel designed to accommodate a stock clutch (See the Unorthodox Racing Ultra L aluminum flywheels in our catalog or go to http://www.unothodoxracing.com). They are made from new pressure plates, a new solid unsprung disk, and new original equipment release bearing. We match all the components to ensure proper fit, function and balance. In our Stage 1 clutch we use a 100% pure Kevlar face on both sides of the disc. On the Stage 2 clutch we mount, with aircraft grade high strength rivets, a 4 puck blended ceramic friction material. By using these matched combinations we ensure a perfect fit, exceptional durability, and maximize holding power without the need for additional pedal pressure over a stock clutch.2) "How does an Unorthodox Racing Ultra G stage 1 clutch hold up to 40% or more power than stock?"Most importantly the stage 1 clutch is designed for most mild to moderate modifications. The stage 1 is designed mostly for street use with occasional strip or track use. The holding power of the stage 1 clutch is increased in two ways. First, the friction plate of the pressure plate is removed and machined nearly flat so that the surface of the disc fully contacts the friction surface of the pressure plate. Most pressure plates have a taper so that the clutch disc does not fully contact the pressure plate surface until it has worn away by 30 to 40%. This means that the clutch will not have maximum holding power until 30-40% of the life of the clutch is used. By machining the plate we are able to attain maximum clamping power once clutch break in/full embedding has occurred (300-1000 miles after installation). This also keeps the pedal pressure feel exactly like stock. Second is the material which is 100% pure Kevlar. Kevlar has a good coefficient of friction. A Kevlar disc can last 2 to 5 times longer than a stock clutch. Kevlar also has other great qualities like its ability to engage smoothly (considering it is used on a solid disc) and the fact that it will not mar, scratch or destroy the flywheel or pressure plate like other materials can.3) "How does an Unorthodox Racing Ultra G stage 2 clutch hold up to 100% more power than stock?"The stage 2 clutch is designed for medium to wild modifications (forced induction and or nitrous on an NA engine or heavily modified forced induction applications). The stage 2 is also designed as a street strip clutch with exceptional smoothness and driveability. The holding power of the stage 2 clutch is increased through the use of a specially blended ceramic material. This blend is designed to allow smooth engagement with solid unsprung hubs. Our special ceramic blend has a phenomenal coefficient of friction allowing it to hold massive amounts of extra HP while still allowing you to daily drive without the harshness of other clutch designs.4) "Will an Unorthodox Racing Ultra G stage 1 or stage 2 cause driveability problems?"Unorthodox Racing has spent many hours designing and testing each model, both on the street and on the track, to ensure that each clutch provides maximum performance without compromising driveability or long-term durability. The design of each clutch assembly is tailored to maintain original equipment type driveability with maximum holding power. The pedal travel before engagement of a solid/unsprung hub type clutch is shorter than a stock sprung hub clutch. The engagement point of any new clutch must be learned by the owner and the shorter pedal travel will be hardly noticeable after the break-in period (300-1000 miles). The most important part of the unsprung design is that it eliminates the springs that cause most of the failures in clutches. These springs have a tendency to want to blow out, break, or fracture from the strain during launches and hard up-shifts. This design also allows the power to get to the pavement faster by not wasting it in the springs.5) "Are special installation procedures necessary with Unorthodox Racing Ultra G clutches?"Included in each Ultra G (stage 1 or stage 2) package are important procedures that must be followed by the installer during installation. Many mechanics, especially dealership mechanics who only use original equipment parts, are not used to solid/unsprung hubs and have a tendency to follow the standard installation procedures for sprung hub clutches. Not following our important procedures in the installation instructions will result in the possibility of a bent clutch disc, which would void the warranty. A bent clutch disc is caused by the transmission being hung on the hub of the solid/unsprung clutch disc during remounting of the transmission. This procedure is allowable for sprung hub clutches because of the play on the springs and the disc. A bent solid/unsprung clutch disc will not engage or disengage properly causing gear grinding, chattering, or even not being able to put the transmission in gear.6) "Are the Unorthodox Racing Ultra G stage 1 & stage 2 clutches balanced?"Each clutch is balanced to standards that exceed original equipment specifications. We only use the highest quality components from the original equipment suppliers and combine them with the strongest discs, hubs, and rivets that are available today. The consistency of the components and materials used in every Ultra G clutch are perfectly matched and balanced specifically for each application. These measures ensure the holding power and long-term durability of our clutches are unmatched in the industry, providing the quality owners come to expect from Unorthodox Racing.7) "Will the Ultra G clutches void my factory warrantee?"Actually the answer is fairly complex. Automobile manufacturers state if a specific component is not designed by them or an OEM supplier specifically for use on your vehicle from the factory then the component voids your warrantee. This area has been a hotbed of controversy for years. SEMA (Specialty Equipment Market Association) has been working feverishly to protect owners rights on this issue because many aftermarket products are viable replacements, if not better in design and function, for the factory component. UNORTHODOX RACING Ultra G clutches are one of many such products, from air intakes to computer chips to exhaust systems. The simple truth is that most dealers are looking for any excuse to avoid working on vehicles modified with aftermarket performance parts. The key is that owners must be aware that these situations can arise and this is clearly stated in the back of their owner's manual that non-OEM products void the manufacturer warrantee. This, not surprisingly, includes performance parts designed by car manufacturers (i.e. Ford Motorsports, TRD, Mazda Competition and GM Performance to name a few).8) "When changing a clutch should I think about changing to an Ultra L aluminum flywheel?"If you are changing the clutch there is almost no additional labor for installing a new flywheel because the clutch is bolted to the flywheel and it involves the same amount of labor anyway. While you can use any stock or aftermarket clutch/flywheel, we recommend our heavy duty clutches and flywheels which are available for almost any application. Stage 1 is for mild mods, street, and some track use. Our Stage 2 is for medium to heavy mods, street, and moderate to heavy track use.

It depends on the setup. If it's just weight, no it won't hurt the accessories. If the pullies are also "underdriven" to slow the accessories down, you will get more hp from them but they may or may not cause a problem. I have underdrive pullies on my Nova and the only time I have problems is when the engine idling in gear with the headlights on. In that one case, the voltage drops to about 12.5 instead of 14. If the headlights are off or the car is in neutral or the rpms are slightly above idle the voltage goes to 14.
