How much Hp will this add

A greddy turbo kit or a drag gen 3 turbo kits(http://www.modacar.com/products/Acura/Integra/MODAFOIN/) let say at 8psi for my 98 ls??? how much whp am i expectin to see...and the revhard stage 2 kit too :rolleyes:

i think there a rule or thum you get between 7-9 hp per psi i think i could be wrong and if i am someone will post it im sure

well 14.5 lbs of boost is 1 bar, and that doubles the output of the motor. Lets say your motor came with 140hp, 14.5 lbs of boost would make 280hp. 7 lbs would be half of 140, which would be 70. Add 70 to 140 and you will get your figure, which should be bout 210.
Hope that made some sense.
