is 475hp 450tq possible from 02 ta with p1 procharger 6psi longtubes magnaflow catback dyno tune don't know what pulleys on supercharger but boost gauge reads 6psi at 6200rpm

 

I made 466 and 475 at 6.5psi (turbo) with fully stock 99 LS1 (other than valve springs and ported TB). I know superchargers take a little power to make power, but with the other mods you have and a moderate tune, I say good deal.

 

It is possible on a dyno but I would question that the timing might be too high for hard driving on the street.

 

thanks for replying the guy who tuned my car said these where good numbers for what i have he said he tuned it safe for the street
