you should get about 235 @7PSI. not too sure if thts correct but somebody told me a formula on how to estimate HP with a set PSI:
X=PSI
Y=engine base HP
X /14.7=___+1=__xY= estimated HP
hope that helps

hey jeffcivic can you simplify the formula. i'm not too bright at math. x/14.7=___ + 1= ___xy = est.hp
does that slash between the x & 14.7 mean to divide? & does the result added to 1 next to the xy mean to multiply everything?

i did it just like it said, the / means to divide, and the small x at the end means to multiply. your first number will be a big decimal, then you add a 1 in front of it, then you will have 1.blahblahblah, then you multiply that by your stock horse power. i have an ls which is 142 hp, with the equation, i got like 228.abunchofnumbers, at 9lbs. of boost.
