383 Supercharged
I'll be starting my 383 buildup as soon as I can, but I had a question about supercharging. It will be a TPI motor (miniram). What supercharger would be the best for it, how much maintenance are they, what kind of chip would I need(if I do this I don't want to have 2 chips burned just because I decided not to supercharge it while building it), how much power would we be looking? Any numbers and tips would be great. Thanks

Naturally aspirated take a second off my time. (See Sig) Keep in mind I have a mild set-up for driveability and emissons.

Hey 91 Formula,I noticed in your sig that you have almost the same setup I want(whole car
not just engine). Would you mind telling how you made it possible, I'm trying
to do it for less than an arm and a leg, I'm only 18 and I just started
working again. But looking at your times I may not want a supercharger. I
don't want to have to put in a rollcage. I think 13's would be fine. Thanks
for your help.
