All Trac turns out not to be as quick as originally thought

Postby 1chewabacha1 » Mon Oct 23, 2006 9:55 pm

To tell you the truth guys I'm a little disappointed in the Stockish... All Trac celica.

Now, I haven't finished my own project CPEED All Trac Celica yet but I'm not so sure I want to continue anymore.

Why? My project MAXIMA has just out-ran a slightly modded All Trac Celica. Okay, the Maxima may have a couple of mods, Variable Intake and ECU, but it only runs a 14.2@98 Mph!

Decent times for a Maxima....
but for a turbocharged Celica with CT26, .54 trim, reflashed ECU, 255 lph fuel pump, FMIC w/ ATS inlet, RPS Clutch, Fidanza Flywheel boosting around 18 psi spiking at 20 on a manual boost controller, this race shouldn't be a problem Should it? Could it be a crappy all trac driver? These things aren't that hard to launch! Even with a lightened flywheel (have tried before).

What do you guys think? Should I just sell the Celica (Would hate to.... such a rare beauty) and get a supercharger kit for the maxima?

Gotta get rid of that ct26. I ran a 13.9 on a TD06 20G at 13psi. Stock airbox, stock ecu, stock fuel system.
Best GT-S STOCK times: 1/4: 14.788 @ 94.98mph 1/8: 9.640 @ 75.87mph
Best Alltrac times: 1/4: 12.2 @ 115mph 1/8th: 7.9 @ 91mph

See this thread.
His mods are very similar to you and he is running 14.1 (and should be quicker, IMO)
What ECU are you running? Exhaust?
What is your 60' time?

i was running against a maxima this past summer. It was hot and my turbo/ic didnt like it, but me and the maxima were dead even. Thats at 12 psi with stock ct26. I think the maxima was a '99. I dont really recall.

Lets see, you have an upgraded ecu that runs more timing then it should and a larger turbo compressor that is pushing 20 psi. That adds up to detonation which equals pulled timing and no power. Lower the boost and you shouldnt have a problem. If you want to keep doing this I'll look forward to a post titled "Why did my motor blow" where someone will explain how pulled timing equals high egts and melted internals.

I would check and see if you aren't pulling timing. I know certain tanks of gas in the winter don't work well with my 18psi/Rom Tune/CT26-46T combo.

i feel my alltrac isent as fast as it should be with its mods, but i do think it might be because im running a upgraded stock turbo...my friends have said its pretty quick though so maybe its just me?

You may just be a bad driver, and it sounds like something could be wrong with your car. Fix it and keep practicing till you get it right. I ran dead even against a v6 maxima with a stock alltrac.

all-trac is not designed to be a good 1/4 racer, it's a rally car dammit :P
When in doubt - increase boost.

Am I missing something here.. or did you forget about listing an exhaust? Or is this thing still running the stock exhaust with both cats?? Because if it is.. then that would explain a whole lot..

Just for reference, if you check out the club race list:
http://www.gtfour.ca/race.html

Kevin Hall ran a 13.913 at Fontana back in 2002, and the only mods he had was 3in turbo back exhaust, a 50trim ct-26, boost set at 14psi, and a straight intake.. Other than that it was stock interior, nothing stripped, and street tires..

I think I still have a low-res version of the video at home..

Sorry forgot to mention that. The All Trac I raced had a stock downpipe, and 3 inch catback (straight pipe all the way through) with a dynomax muffler piece (gets the job done).

All these 13 second runs though only have a trap speed of 99ish. My Maxima is trapping at 98ish just all motor (and that All Trac I ran had absolutely no chance at the top end. Lower ET's mainly due to the AWD but I NEED highway power as well.

Side note: Stock 4th maxima's run high 14's at best (I've seen a couple running 16 flat at best) and auto's run mid 15's at best. Trapping anywhere from 92 to 95 at best.

My Maxima runs 14.2 and traps and 98.... probably not as slow as a stock all trac that's for sure.

You guys didn't see my last question? Should I just get a different project or continue with this?
