Ok I have a 04 GT with a 5spd, and have now desided to go with a S/C after my warrent goes instead of doing most of the boltons.My problem is that I dont know which S/C to go with.I was thinking either a procharger p1sc or a KB unit.I would like to know first off how much power each will make on a stock car (just through out a number, it doesnt have to be dyno proven just in the ball park).Second, which is also the most important, which will keep my engine alive longer.I would tend to think that the KB would kill my 4.6 quicker because it runs full boost alot quicker than the P1sc, but I may be wrong.Third, I may buy a cobra motor and lower the compression and fully forge it, and which one would be easier to switch from a GT motor to a 4V motor.Forth, which will deliver better milage?Fifth, which will be quieter as in that whine sound.Sixth, which in your guys opinion is easier to install.Seventh, give me a guess on how many miles I can get out of my engine with either so I know how long I can expect the engine to last.8th, will my trans and rearend hold up to that power with the 315s, that I plan on buying as soon as I get the S/C, hookin in the back.9th, will those 315s be able to hold the power (not DRs).10th and final Q, what boost range would be safe with either one I go with?I was thinking the KB 9 psi if I go with that, not sure about that P1SC though, should I go with stage I or II?Also, please remember my above Qs and concerns before you answer this question.If it helps any on the relability Qs, I usually shift my car at like 1800RPMs and for the most part dont really get on it that much and when I do its mainly through 1st, 2nd, and the chirp into 3rd, then I let off.I havnt even hit the rev limiter yet and have only been to about 90MPH
