Ran my 3sgte at the track, 1/4 mile time Options

[Coomer]

That's awesome Dave!

And yeah, mid-14s are pretty quick. What a lot of you may not realize is that even though it's a fourteen second car, it probably feels faster than that once it's moving. I've ridden in a couple FWD cars that run 14s, and even though they only run 14s at the track because of their traction problems, they are fast, fast cars...once they're moving, both of them feel really fast. I bet that both of those cars(Both Civics, one with a turbo B18-something and one with a built H22A) would beat an EVO or an STI from a roll.

Dave, what were your sixty-foot times on your runs?

looks like iam gonna have to finish up the last few things on my car and break 12s for you guys.... sure you can buy a camaro, add 150 shot and intake and headers and break 12s easily, but someof us like our celis and its why we do this..... for a fast car, i would get LS1 camaro on spray, and it would be automatic not stick....

Thanks to celica3sgte, super, xxx, 5sfeturbo, lagos and a few others for all the support. Some of you other guys must not read the full posts or something???

3sgte at 11-13 psi, 5s tranny, 18" regular street tires, and taking it easy off the start should explain it all here but ...... some of you dont realize what all this means!!!! I never launched it, unless you consider starting off at 1500 rpm a launch?

by the way for those of you who keep knocking on the boost levels: i have hit 17psi in my car and it will hold there with the stock turbo so it is very possible to run higher boost but....i just dont trust it to run it that way. and like someone else said.... the turbo wont last as long at such a harsh boost.

everyone has a right to an opinion..... but i would rather take advise from someone with first hand experience on these issues, than people thinking they know the facts.

gains might drop as boost is increases but the key word here is "gains".... you are still gaining power until you hit the point where more boost is = or less than lower boost hp!!!!! right? do you see to point here?

basically if I say just to prove a point:
12psi =225 hp
13psi =235 hp
14psi =245 hp
15psi =255 hp
16psi =257hp
17psi= 260hp
18psi= 260hp

17 psi is where i would stop gaining so that is where the turbo is maxxed out at!!!!
so there is no point in going to 18psi ... but there is still 2hp diff from 16 -17 so there is still a gain even though it is very minimal. this is what we people with swaps are trying to tell all you other people who are confused or dont understand.
hope this clears up some issues,
dg

CT26 Efficiency
Read
Read those. You have pitted efficiency against gains. Now your saying that the 3s wont see much gains after 10psi because the CT26 is past its prime efficiency. This is a generalized and subjective statement. What do you mean by much gains? Thats where the subjective part comes in. Your opinion of "much gains" can be different that anothers. But the efficiency of the CT26 increases or decreases with factors like ambient pressure, intercooler etc. etc. Now the STOCK intercooler will allow the CT26 to work fine until 15lbs, and it will not stop producing any sort of gains until after that. Then the problem of hot air can come into play and a more efficient intercooler is needed to cool down that air.

WE ALL WIN!!! Lets focus on the 1/4 mile time. Come on guys its all Love.

yeah shid, i know what you are trying to say, but having a theory and owning a 3sgte are 2 different things.

dave, i wouldnt run your car at 17psi. there are a lot of guys that go to the tracking with this type of thinking and dont make it home. haha

id say 15psi max.....later model mr2s had fuel cut raised to 16psi on the same 2nd gen motor, so you should be ok up to that point but not boyond it. also, see if you can buy race gas before running it again...

oh, and scan your time slip for us!

[5sfeTurbo]

Thank you for not making me ask what CFM meant.

Shid not to be a jackass or anything but you have no idea what you are talking about. First of all PSI has nothing to do with the limits or life of a turbo...its the pressure ratio that determines its limits. You shouldn't automatically assume what people say is true.

good job dave ! put some slicks on those 15inch wheels.

I have been in dg's car..... stock boost would make you 8itches say holysh:t. but what do I know ?

I would love to see some more track times

Yeah i forgot to say great job dave. 13 seconds is easily in reach..and that is f'ing flying!!! an 11 second car is such a fast 'n furious comment... having an 11 second car is almost guarenteeing that you have no streetablility...its all track. What fun is driving a car that sucks on the street?

[Supersprynt]

I was at the track with a couple friends running their cars. I have a friend with a 95? Mustang GT. Full exhaust, GT40 intake manifold. Now this is a V8 and he ran a 14.36.

I have another friend with a 93 Civic hatch Si with exhaust and intake and he ran a 15.8.

I have a short video of a 70's something or other I forget running an 8.9.

If you read that post that Super posted you'll understand that psi is one of the factors in determining pressure ratio... yes by turning up boost you are increasing pressure ratio... but it isn't the only factor, there are ways to offset that high amount of boost.

lol, how come my car ran 14.01 and it didnt bring up such a long post.... anyway, i did the same , 14.4 (my friend ran the 14.0) ... it was my first time at the track too... but with 3rd gen lsd tranny i launched it (spun)... because i cant drive and i have ****ty tires...

i put on 15s , they were 205s vs my 225s but they were drag radials from my friends neon and smoked every car that was out there... srt-4 with few mods, sentra SER on spray (that beat the srt-4) , Pontiac GTP on SPRAY (that beat an STI), didnt get to race the STI , but went up against a turbo cavalier and killed it... and this is all in a row... like i lined up ... raced a car, beat it, and i came back to starting line to find another car, and another, plus like 2 re-runs... all of them got smoked with decent tires launching at 11psi switching to 15 PSI at 3rd gear. all UNTUNED.

anyway, as a race car... the 3sgte powered celica dominates FWD cars 1/4 mile and highway wise with the right tires and driver. i think the 3sgte has the biggest stock turbo of any 4 cyl engine.

as for turning up the boost.... just get water injection and/or race gas... if you can get your car tuned, that would be awesome... just go street racing for a while, learn to drive... and then head over to the track ... and when you blow your turbo, upgrade it to a 60-1 or any of the nice mr2 trubo kits out there, they have allot for 2nd gens.

for the launch, learn to work the gas pedal... with decent tires, do a low spin.... maintain the low spin threw out first and 2nd gear, and then when you hit 3rd floor it and turn up the boost if you have that option.

sorry for blablering, ive been out all nite racing and its 7am and i just got home and i gotta get to school by 9 am

The SR20DET I believe has a bigger turbo than both the 2nd & 3rd Gen 3s's.

The 60mm trim would be pointless I wouldnt go above 52 on teh ct26.

okay, only 1 engine soo far, not bad...
