I am currently upgrading my car for some serious drag racing and I am having difficulty deciding whether I should build a nice turbo setup or use a supercharger. I will be building a small block chevy engine for one of these setups and I would like to use a carb setup or is fuel injection the way to go with a turbo setup? I have looked at the banks twin turbo sbc kit and am wondering if anyone has bought one of these kits, and how well did it install? For the supercharger guys out there what do you recommend using a procharger or a twin carb setup? I wanna start out with a setup that will get me 850-900hp. With all this in mind I would also like to try and use 91 octane for the weekend cruising around town but run 100+ octane for the track days.
