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

 

i would try dfi and a procharger

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.

 

I had the short block built for $5000 incuding parts. Parts are:
1) 350 block
2) All Machineing
3) 4 bolt mains with splayed billit caps.
4) Scat 1pc rear main seal 3.75" stroke crank(nodular iron) $250.00
5) Wiesco forged pistons
6) Eagle H beam rods

Heads I got out of Summit racing. I did every thing else.

personally i would go with a tpi procharger w/intercooler........definate potential to make some crazy power.
