Quote, originally posted by WENIS Â»Hmmm not sure if you misunderstood me... maybe I'm misunderstanding you, but I'm not getting rid of the SRT, just seeing if my Vibe can be made almost as fast without getting too crazy. I think it'd be funny as hell to spank Cobalt SS's, RX8's, WRX's and anything in the high 14's, low 15's range with a Vibe. Just don't see many Vibe's/ 'trix's in the mid 14's you're NOT going to beat a WRX with just mid to low 15's. LOL. sorry.... especially the new 2.5L WRX's. and I know you are not getting rid of your SRT4. I was comenting that when I switch cars with the hubby for the day, going from my 2.5L Turbo stage 2 to his base vibe 5MT w/ I/E/ECM, it's still very much NOT the same... however, it makes me miss having an MT, but then I switch the car to manual shift (but still NOT the same as MT ).Quote Â»True, I could pick as much hp in the SRT with a 3" turbo back exhaust, & wga set to 18psi as I could with stage-2. A friend of mine is running that set-up and dyno'd at 268hp here in Gap pa. He ran low 13's @ 108 on stock tires down at Cecil county raceway MD. The thing I like about stage-3 (and even stage-2) is the "dial a boost" feature with the "turbo toys" dash panel. You can keep the boost dialed back to streetable levels, then turn it up when you line up with... an '03 Cobra for instance http://www.srtgurl.com/my_SRT-4.htm
(scroll down to the dyno section, and look at the 3rd one down, same mods as my friend (plus some other non-power adders).dial a boost would be nice as long as you don't blow up your engine. LOL. i run about 15 psi and on all stock parts, gutted uppipe, midpipe, and downpipe with ECM flash 13.6 1/4 ET in my AUTO. an MT with the exact same mods and set up will run low 13's. That's about $600 for the ECM and a day to knock out the cats in the pipes. still very very different than running a base vibe. these guys with the s/c and all these mods so far have been talk talk talk and nothing to show for it. i think devlop (had a turbo'd vibe) went to the track, but can't find any of his recorded times. i know they were pretty good, at least in the 14's if i remember correctly. with the vibe being so lightweight, low end torque will get it flying! Quote Â»I think Unichip requires high octane as well doesn't it?My goal is to surprise some ppl in mid 14 second cars when I'm in the VIbe. I think since the base Vibe MT weighs 2700lbs and the Cobalt weighs 2659lbs, and both have a relatively low flat tq curveÃ¢Â€Â¦ you wouldnÃ¢Â€Â™t need to add that much power to run with it. If the VibeÃ¢Â€Â™s motor could handle it a just 100shot alone would do it.My ultimate goal is to beat the crap out of the Caliber SRT-4 but I'm not sure that's possible with 1.8L and on stock internals. I swear that 300hp is going to be at the wheelsÃ¢Â€Â¦ to bad itÃ¢Â€Â™s so dang ugly. The reason I think itÃ¢Â€Â™s at the wheels is because the neon SRT makes 250ft. lbs of tq at the wheels right now even though itÃ¢Â€Â™s advertised at the crank. The Caliber SRT-4 has the same engine, but with a 3Ã¢Â€Â exhaust stock (neonÃ¢Â€Â™s is 2 1/4), better flowing head, slightly higher compression ratio, and most importantly VVT. They say it makes 260ft. lbs. of tq @6000rpmÃ¢Â€Â¦ again they say itÃ¢Â€Â™s at the crank. I canÃ¢Â€Â™t imagine with these changes, the motor would only make 220wtq (30 less than the current SRT-4). That means, if the 260tq is at the wheels, at 6000rpm it will be 297hp at the wheels (260 x 6000 / 5252 = 297). And no less driveable than a stage-1 SRT (same tq levels but crappy tq curve).no, a unichip does not require premium fuel. it depends on what and how the tune is set up, just like any other ECM. with it being the vvt-i engine, unless you really mod the hell out of it, it's not necessary to spend the extra $$$. it's not like a F/I system that you throw on ECM and you instantly get 30+ whp! it's more like 5 hp up the powerband, but it certainly makes a difference on the low end. less maintenance and upkeep as well as being pretty safe. as for #'s of the SRT4, i don't really know. the engines are impressive at the very least, however, i'll stick with my AWD turbo.
as soon as I'm allowed, it'll be upgrade time to 330+ awhp bliss! still, the vibe surprises people. they don't expect it to be as quick as it is... and i have to agree with you, it's a very attractive vehicle (imo), one of the reasons I fell in love with them back in 03. plus, the practicality is just awesome! it'll be interesting to see the new caliber srt4's... i want to test drive one when they get them in, see what they're all about and all. doubt i'd ever buy one though. i like the looks, but the vibe is better.
