Horsepower Question (Ricer)
Does anyone know how to figure how much HP you lose going from the FW to the street? My friend just ran his Supra Turbo :rolleyes: at the track and wants to figure out how much HP he has. He ran a 15.289 @ 91.5MPH.
Any ideas???? Thanks guys!

Typically you lose 15 to 25% from drivetrain friction depending on the transmission. Check out http://www.smokemup.com/auto_math/index.php
Also http://www.smokemup.com/auto_math/hp_mph.php will give you hp from 1/4 mile trap speeds. This is what I got from your info:
You Entered:
Vehicle Weight - 3400 (lbs)
Trap Speed - 91.5 (mph)
Drivetrain Loss - 20 (%)
Results:
Rear Wheel HP - 176.9
Crankshaft HP - 221.1
Using E.T. and http://www.smokemup.com/auto_math/hp_et.php I calculated:
Results:
188 Rear Wheel HP
235 Crankshaft HP
You get ballpark numbers, no more.

Re: Horsepower Question (burners)
Thanks for the info! It's a '91, auto, single turbo with a Taga top. It's actually a pretty nice car and it runs well. He ran it last night just to get a base line of what it would do (it is 100% stock) now he (and I I suppose) are going to try and do a few things to it to see if we can get him a little more HP.
I told him the next time he runs it at the track I'll bring my vette and we'll see what happens!! :lol: I shouldn't laugh, I don't know what mine would run...never done it.
Thanks again everyone! :cheers:

Still, it may run 11s, but at 140mph. Easy 9-second capable. Wouldn't want to race it from 20mph.
IMHO, its a lot easier to build a drag-only car vs. something that can do a lot of things well (which defines "sports car", IMHO). It's all in what you want out of it, and that will vary from one person to the next.
