Which power adder for this SBC Engine?

[66chad]

The setup u have will work with straight supercharging at 10.5 to 1. The alcohol and or intercooling does work great. A serp. belt will run 25 psi up to 1000+h.p. with the right setup u need to run a extra idler on the bottom of the belt and a large pulley on the crank so the supercharger pulley can be larger for belt traction. The cog setup doesn't work well on the street and is not necessary unless u want huge numbers. My first supercharged motor was 10.5 to 1(93 octane) and I ran 14psi with alcohol and boost referencing timing. Boost makes them hit so much earlier. Do your homework early it will make a big difference. Cam selection is important and will help drop the cylinder pressure which will help with your compression ratio. I highly suggest talking to Rodney at Joeblowracing(8058162587) he knows a lot and had good prices also take a look at www.turboconnectionracing.com. Jim set up a LS2 GTO 11 to 1 supercharged car that makes over 700rwhp at turboconnection. Just do your homework and talk to the experts that work on these cars all the time. Turbos are also awesome u just have to plan on your goals and bank account.
