NASA TT4 prep. Estimates of current hp needed
 
I'm trying to fit my car into a NASA TT class. I'm trying to estimate my power to weight. I'm currently running headers, cat deletes, aftermarket pipes, and an underdrive pulley. Is anyone running a similar setup? Any ideas what kind of wheel hp I can expect?

:cheers:

What year/motor is your car?

If its a 97-99 2.5L engine, then I'd think that you should see around 190-195hp at the rear wheels.

Yep, 2.5 thanks.

Aren't you going to have to get a dyno test to turn in on your book?

Sure am, I'm trying to see how close I'll be though before I pull anymore weight. It seems like the Boxster is a pretty good TT4 fit.
