Okay.. I was just doing some thinking about power output:
(~) = approximation
420a stock = ~116hp @ wheels
420a @ 10psi = ~240hp @ wheels

Equation : 140/116 = 1.21
Therefore 240hp x 1.21 = ~290hp @ crank

Although the actual loss may be greater w/ more power,
so the hp @ crank may actually be greater. Now the thing that
concerns me is that stock internals can hold up to ~300hp

I may be way off on this one or right on the money.. Need some feedback on this.. what do you guys think? is 10psi max for
stock internals or what ? (this is after all just paperwork!)
