Well i guess I finally bumped Jarrett off as the quickest na-t Supra.

Made 4 passes today trying out slicks.... they are really interesting to drive. The back of the car wanders all over the place, getting worse as you lower the air pressure in the tires. Anyway, I still didn't get my air pressure low enough to get a real good launch. Got a 1.76 60'. I'm heading back to the track tomorrow to see if I can do better.

Excellent job Dave you are now officially the man (not that you werent before). Hey im in college right now and out of college or if some how i run into a large sum of money in the process of college i was wanting to get a turbo kit for my NA i know there is a few boys in Springfield that have the badass Sound Performance kits. What would you suggest if i wanted around 450 horsepower or more much like your running? You got a mix of Powerhouse Racing and Sound Performance parts right? Also you have Cams in your car at all? I noticed on a web page someone posted the other day it looked like i believe crower now makes cams for the NA AND the TT.
Thanks

Thanks guys.....

UPDATE! 10.992 @ 123.3 mph!!! Whoohoo! I eeked out a 10!! I got to the track late and ran with it completely heat soaked. But I got the slicks to hook up well and got a 1.62 60'. Later I cooled the engine well and ran 127.5 mph, but messed up the launch bad on that run. It's not all that easy putting together a good run...

Ear Candy: I'm running a Powerhouse intake manifold and fuel rail. I'm running a SP header/downpipe and SP63. The biggest obstacles were just getting everything to work together. Lar's turbo/converter combo help a lot getting out of the hole. Fuel system = 2 Walbro GSS341's through a -6an line and filter to the rail. 780cc low imp injectors with a mkiii solenoid resistor. HKS VPC with a mkiii chip.

Thomson: SP's na-t header is sweet, I'd recommend it. They could also hook you up with the right turbo and injectors ect. I just have the stock cams, but I might look into the crower ones.

That's a great ET, and the MPH when cooled shows you have more left in the car.

Two thumbs up

OMG Dave you in the tens now i mean geez leave some hope for me when i get to run my turbo stuff on my car outta college hehe. How on earth an i supposed to compete with that now. That Powerhouse Intake rocks because the spark plugs are SOOOOOO much easier to check and its on the cold side of the engine. That is something i may look into because running high boost you gotta check your plugs regularly and although im an expert at it now taking the throttle body outta the way all the time gets to be a pain. Thanks again for the info and for makin NA HISTORY *writes Dave down in the NA history book for having a 10 second quarter mile*
Later
