What kind of weight reduction? The Supra is a fat one, if you remove AC, ABS, and PS; it will be a fat one that doesn't have AC, ABS or PS.

I say tires amd suspension.

If you have a 5 speed, I'd go with a lightweight flywheel, aluminum/cf driveshaft, lightweight wheels. For auto still get the ds and wheels.

You're going to have to do alot of weight reduction if you go that route. I'd combine abit of weight reduction with more power upgrades.

People usually say that 100 lbs lost is a tenth of a second faster. Look at some math:

stock weight w/avg male driver is ~3800 lbs
stock power at the crank = 232 hp (89+)

Stock Power-to-weight ratio is: 232/3800 = .061 hp/lb
100lbs weight reduction P2W ratio is: 232/3700 = .0627 hp/lb

solving to find out how much power is equivalent to 100lbs reduced:

.0627 = x hp / 3800 lbs => x hp = .0627 * 3800
x = 238.26 hp or about 6.26 hp

So you have to decide what would be more efficient (cost, practicality, etc) 100 lbs reduction or 6.26 hp.

BTW, the scale slides everytime you upgrade your car cause you will have a new baseline. This will help you determine what it will cost you to get to where you want to be.

Also the a340e tranny is only good for 400 horses, after that it will break so you will probably have to go with a built a340e or a different tranny setup, which will be more expensive.

Good luck with the 11s! Hope you make it.

in all reality, get suspension, engine mods, FUEL MODS, wheels, and some weight reduction. If your crazy enough swiss cheese the chassis and frame work.

gixxer is FTW. Those are the type of numbers that our cars should be doing. I gotta say, that is pretty impressive for 251rwhp. Kind of shocked, actually.

Annnnyways,

99% of the time, the faultyness in our cars is the DRIVER. ;)

Eat that one for lunch.:evil2:

gix: you're only making 251rwhp? on a 57 trim? something sounds wrong. what was the boost level? i'm pushing 289rwhp on a stock dying turbo... creeping from 10psi to 15psi.

and i really mean my turbo is dying. it has chipped impeller blades, shaft play, and the death whine.
