I'm quite experienced in car "stuff". My ultimate plans include an aggressive rebuild of the old 3.0... selective porting, and a supercharger.
I plan to build an engine supercharger combo that's capable of supporting around 15 pounds of boost. I've done it before on a suburban, and on a blazer... BUT those two vehicles have MUCH better aftermarket support.
My plans don't include working on the intake side of the engine nearly as much as the exhaust, engine internals I'm unsure about just yet... what I need is to acquire a spare 3.0 engine to play around with. Measure stuff and calculate tolerances under virtual loads...
Anyway I know I can do it but money is (like most of you) my biggest problem. For other people where money is not an issue... the job is easy.
Personal opinions on the matter I believe a centrifugal supercharger is the best way to go... surpassing both roots and turbo possibilities. The 3.0 stock makes most of it's power in the Lower RPMs the lag on a turbo would waste potential power in my opinion and the roots sucks air after the throttle body whereas I believe it is best to push it in. not only that but higher intake velocity develops more low end torque (why do you think GM developed the very successful vortech concept) and a roots system requires modifications that significantly slow the intake velocity.
I have in the past rebuilt a vulcan engine (on a ranger) but that project greatly pales in comparison to what I have in mind for my LX.
Questions are welcome, I hide nothing! Well almost
