I have an 03 GT and am about to put a 9psi Kenne Bell 2.1L interooled s/c on it (most likely with the 90mm meter, 75mm TB and Big Tube kit, and their cold air intake) . I see a lot of people here have done this on the stock internals, so I'm not so much worried about that. What if I ever wanted to up the boost, or switch to the bigger blower? What would need to be upgraded? What are the weak points in the 4.6L SOHC engine under boost?
Also, what about the clutch, 3650 tranny, and rear end? I figure I'll need a better clutch when I get the supercharger, but will the transmission and rear end hold up to hard launches at the strip? My car only has about 30k miles on it, but it was my first manual transmission car, and i drive like a madman - for example, my apartment building is on a 50mph 2 lane street, so every time when I leave, i'm pretty much flooring it and powershifting into 2nd (whether I have to or not) - so the gears have been messed up a little.
I've read in atleaset 1 magazine that the motor can "safely handle up to about 400hp." Is this true, or does it have more to do with compression ratio's and/or boost? ie, if i make say, 380rwhp with the blower above, and put in a serious cam and maybe some other mods, and break 400rwhp, do I have to start worrying about it? Or is it mainly just if I up the boost?
