7 psi shorten engine life?

RE: 7 psi shorten engine life?
Well, since a supercharger increases pressure inside the engine, then by common sense, engine life should be shorter. But if you have well built internals then it shouldnt be that bad.

7 psi should be fine. A good tune is everything. There are guys here running 10+ psi on stock internals for thousands of miles so far, and they don't have issues. Hell, ford makes a 6 psi kit for NPI motors and another for PI. Since they are very conservative, you can probably run 8 psi with a good tune and still have a motor last 150K.

depends on the fuel you use as well, a friend of mine has an 03 stang running 18 PSI on stock internals and has comitted to leaded racing fuel for good... engine has been fine for 2 years so far... I wouldn't recommend this, just giving you an example
