No KR for me.. 20 deg of timing.. and 91 to 93.5 oct Gas
You can run more boost than 4 to 5 psi W/O the IC just lower your timing tables..

The Best V8 Stories One Small Block at Time
I was running 8psi and getting a touch of knock up top so we backed down on my GTO. The car was making 550rwhp and does have a single IC that came with my Procharger.
Now I run 11psi with methanol and get no knock all the way up to 603rwhp. I am quite happy I put methanol on my car.
I went from 11psi with no methanol and only making 570ish rwhp to adding the methanol and making over 615 on my best hotlapped pass on the dyno! I talked to my tuner and decided I wanted it to be safer than that so we pulled a degree of timing and ended up just over 600rwhp!
Methanol is one of the better things I have done for my setup. Wish I would have done it when I was running 8psi so I had another comparison for you!






Alky is great for pulling heat out of the air but it does have limits. Having both would be ideal.
