You'll be fine, you aren't going to press 35PSI of boost through it anytime soon.

1 more question?is it a 7% gain per pound of boost?and 1% overall if intercooled?i saw it somewhere but can't find it.with my calculations i should be at 225 hp(not at wheels,prob crank).it is 7% *10 psi= 70% increase in horsepower,then add 1 percent for intercooler,that makes 71% more horsepower overall.so then .71*130(neon base horse?) =92.3 additional hosre power.130+92.3=222.3.is that the proper table for horsepower gain?

if you think about it what your doing is increasing the pressure in the motor. ave atmospheric pressure is 14.5 if you add 7 lb of boost then it is a 50 percent increase in pressure so theoretically adding 50% more power. 130 to the crank + 7Lb = (HP*50%)+HP= new horse power . then you have to take into account drive train loss and other innefficientsies.

thats always been how i look at it. i dont know if im right or wrong

i also know i dont know how to spell anything.

yeah, doubling atmospheric pressue doubles engine power
