Gear Ratios for Manual Transmissions?

[SeattleJeremy]

I found the Gear Ratios for the Automatic's in this thread.http://forums.genvibe.com/zerothread?id=4234I was wondering what they are for the manuals. Also, how difficult is it to change out teh 5speed for the 6?

(robdog)« » 7:33 PM 3/19/2004 Reply EditI'm with Robdog on this. If you use the data provided above by Nova: 6,000RPM in6th is 6000/0.73/4.53 = 1814.3 wheel RPM. With a diameter of 24.9" (perTire Rack's data page), the circumference is 24.9 x 3.1416 = 78.2", so thecar will travel 1814 x 78.2 inches in one minute. Divide by 63,360 for miles= 2.24 miles per minute or 2.24 x 60 miles in anhour = 134.4 MPH.So, assuming there is no speed limiter, one would have to reach a true 135MPH to hit lift. Keeping in mind that the 2ZZ puts out only (Damn! Where's a dyno trace when you want one?) maybe 125-130 wheel HP @ 6,000 RPM before lift, it would seem you'd need one humongous downhillto make it happen!===================================================================================Kissfan79MemberOffline323 postsHonolulu HIJoined 3-14-2003 Re: Hit lift in 6th?

Would have to look at a dyno curve, but if you had just enough power to hit lift on a downgrade and if lift added 10 HP at that RPM, it would take you from say 130 to 140 HP = 1.077. The cube root of that is 1.025, so your new top speed would be 135 x 1.025 = 138.4 MPH.===================================================================================Kissfan79MemberOffline323 postsHonolulu HIJoined 3-14-2003 Re: Hit lift in 6th?

(Kissfan79)« » 11:44 PM 3/21/2004 Reply EditThat sounds possibly like peak wheel HP in stock form.From all accounts that I've seen, the GT is not electronically limited so it is drag limited (at 129 MPH on a flat surface as previously noted). MadBill's calculations would probably answer everything the best.MadBill, you calculated for lift beginning at 6,000 RPM, but I think the actual point when lift will engage is 6,250 RPM, so it would be even harder to hit lift in 6th gear. It would have to be like a decent to the bottom of hell to be able to accomplish this. As you said, it requires exponentially more force per unit to accelerate the vehile as velocity increases. So even if you did get 'er rolling downhill fast enough to hit lift in 6th, the forces acting against you would be so great that you probably would not even feel the acceleration. I wouldn't want to take a GT in stock form that fast anyway, the thing would be so unstable at that high of a speed and I doubt that the tires are rated for speeds that high as well.02/14 can go take a flying leap right off the calendar.===================================================================================ALi3NMemberOffline173 postsHouston TexasJoined 11-17-2003 Re: Hit lift in 6th?

I would agree that it is not 100% accurate, but there is no way it would be off more than +/- 3 mph...unless you had a front tire that was half flat or you were airborne. I have to agree on the 6th overdrive thing. I can get the car up to much higher speeds if i just let the car tach out in 5th rather than trying to accelerate in 6th in the triples. On my way back from vacation yesterday i got a really straight flat stretch of empty road and hit 139 mph (+/- 3) in 5th. If i remmber correctly i was at about 7k on the tach and still had a little throttle left under my foot. The car just does not seem to have the torque required to do much in 6th. ...and if this car does have an electronic limiter it is set way higher than i will ever go.Am i the only one that has made the speedo read 139?ALi3N aka Dj ViP3RThere is a force through the euphoric beat causing uncontrolablemovement of your body, I am that force.

If someone had a CAI and say a magnaflow exhaust where their HP was pushing 200 at the flywheel vs the stock 180. I would think that there would be no problem with the car going past the stock 129 drag limit.

Mine indicates just over 120 KPH (~75 MPH) @ 3,000. I can hit ~93 MPH in 3rd gear, and can't pull some medium hills in 5th without losing 10 MPH...===================================================================================futseal04MemberOffline346 postsMoore OKJoined 5-24-2004 Re: Hit lift in 6th? (MadBill)« » 1:59 PM 5/27/2004 Reply EditThe 6 speed would help the base get better acceleration, due to the fact that the ratios are closer, and therefore keep the engine in it's powerband. The GT would get the same fuel economy with either tranny, since the ratios in the top gears are the same. The reason it doesn't is beacuse the final drive (or in RWD cars "axle ratio") is lower (numerically higher). If the GT had the same gears (3.94) as the base, it would get better gas mileage, but acceleration would suffer due to not being in the upper part of the rev range under WOT (or out of lift). The GT has this ratio due to the fact that most of the power lies above 6k, and 4 bangers as a whole have lower final drive ratios. V-8's usually come with anything from a 3.27 (Mustangs) to a 3.43(LS1/LT1 Chevy's). Overdrive for the 6 speed in those cars are a .5, and that is why they only turn about 1200 at 60 in 6th.'04 Vibe Base'97 Buick Riviera S/C'01 Suzuki SV650S===================================================================================goodvibeMemberOffline811 postschicago ILJoined 7-28-2003 Re: Hit lift in 6th?

Other factors include removing the roof rack crossbars (if not the whole rack),closing in as much of the grill as possible without causing overheating, building a vey low front spoiler under the nose to keep the turbulent airflow out from under the car, running mfgrs. max specified tire pressure to reduce rolling resistance, making sure toe-in is near zero, ensuring no brake drag, etc.Given a straight and level deserted road, it's easy to check the effect of various factors re drag. You just accelerate up to a fast but safe speed, pop it in neutral and time the interval to coast down to say a 20 MPH lower speed. Repeat several times in each direction, toss out any obvious outlying results and average the rest. Then change something and compare results. I tweaked a front spolier for my Metro this way to get best results and gained 2 MPG.===================================================================================futseal04MemberOffline

This is true for any add-on, but some kits have been tuned to provide downforce at speed, at the expense of added drag.Remember that to double speed, you have to cube power (all other things constant). For example, if you need 200HP to hit 100MPH, you would need 800HP to hit 200MPH.'04 Vibe Base'97 Buick Riviera S/C'01 Suzuki SV650S===================================================================================Smokin' RubberMemberOffline664 postsSeattle WAJoined 4-3-2003 Re: (futseal04)« » 3:07 AM 6/17/2004 Reply EditActually some body kits actually do reduce drag.

There was an article is sport compact i believe where they put the XS kit for the GTS on a Matrix XRS.===================================================================================Emerica13MemberOffline164 postsNovi MIJoined 1-13-2005 « Re: (Smokin' Rubber)« » 4:06 PM 4/20/2005 Reply EditOkay thanks. Also, any idea as to the price of the tubing and other stuff you would need, besides the actual turbo kit?2003 Shadow Vibe GT===================================================================================Smokin' RubberMemberOffline664 postsSeattle WAJoined 4-3-2003 « Re: (Emerica13)« » 5:07 AM 4/25/2005 Reply EditNot a good estimate but I'd guess that stuff would run you quite a bit.... since most of the money for the turbo comes from the piping and the labor it takes to figure out the piping routes and install them. I'd think it would almost be easier to buy the components seperate (turbo, intercooler, BOV, maybe injectors, etc) and then just find a shop to do the piping it will still run you about 3,000 as opposed to 3,000 + changing the piping and such. So really getting it custom do is more cost efficient. I am planning though not sure when to get a custom kit built (and spending the 10,000+ for internals and such) to put out some serious HP. The only thing is I think I'm gonna push it back a year or two (was supposed to get it summer of '06) so I can get an actual job and get done with school so I can actually afford paying the 10 G's.As for the stuff you would need besides the turbo kit it all depends on how much HP you want to make and how much you want to spend. You can add new sleeves, pistons, rods, fuel pump, engine bolts, valves, valve springs, ECU, etc all of which let run higher boost or create more HP.===================================================================================Emerica13MemberOffline164 postsNovi MIJoined 1-13-2005 « Re: (Smokin' Rubber)« » 2:42 PM 4/25/2005 Reply EditThanks a lot!

I was beginiing to wonder if my speedometer was off, perhaps reading low.Quote, originally posted by NovaResource2 »5th gear in the 6-speed is also overdriven (overdrive is a gear ratio that is less than 1.00):1st : 3.172nd : 2.053rd : 1.484th : 1.175th : 0.92 (overdrive)6th : 0.73 (overdrive)Reverse : 3.25Final Drive Ratio: 4.53BTW, the 5-speed also has 2 overdrive gears:1st : 3.172nd : 1.903rd : 1.314th : 0.89 (overdrive)5th : 0.73 (overdrive)Reverse : 3.25Final Drive Ratio: 3.94Quote, originally posted by MadBill »I'm with Robdog on this. If you use the data provided above by Nova: 6,000RPM in6th is 6000/0.73/4.53 = 1814.3 wheel RPM. With a diameter of 24.9" (perTire Rack's data page), the circumference is 24.9 x 3.1416 = 78.2", so thecar will travel 1814 x 78.2 inches in one minute. Divide by 63,360 for miles= 2.24 miles per minute or 2.24 x 60 miles in anhour = 134.4 MPH.soMPH = (RPM/(gear * final drive ratios) ) * ((60* circumference)/63360)if I use MadBill's circumference for standard tire of 78.2, then the equation simplifies toMPH = RPM / (gear ratio * final ratio * 13.5)for my 5 speed, this means that in fourth gear at 3000 rpm, I should be going 3000 / ( 0.89 * 3.94 * 13.5) 63.4 mph and 3000 in fifth gear should be 3000 / (0.73 * 3.94 * 13.5) = 77.3 mphThis morning on the way to work I checked, and my speedometer is hitting these RPM/MPH number pairs right on, or at least close enough that I can't tell the difference. So now I know that there are a lot of slow drivers on the roads around here.would be interesting to see how close other people's manual tranny vibes come to matching the equations.===================================================================================slowvibeMemberOffline34 postslittle rock arJoined 10-4-2005 « Re: Hit lift in 6th?

I wonder why that didn't come up in my search...Thanks Joatman!Guess I won't be switching to the 6speed in order to get better top gear ratio. Edit: Oh I see now, I only searched in the title.
