Boost and Compression

[2broke2gofast]

I built my motor a little over a year ago, anticipating putting nitrous on it in the future. I've recently ran across a deal on a turbo kit and need some advice.

I have a static compression ratio of about 10:1
and a dynamic ratio of about 9.3:1

The cam I went with was a supercharger cam and is designed to bleed of cylinder pressure, but would I be able to run pump gas with this combo on 5-10 psi?

Any advice would be appreciated.

yeah you will be fine. I am running 20lbs on a s/c with 9.5:1 and i'm on pump gas.

Turbos actually for some reason can use more boost and put out higher numbers on 93 oct. but running 5-10 psi even with a s/c you are fine on pump gas.

the main reason of using race fuel or much higher oct gas is to prevent misfire. running lower compression takes the chance of misfire down a lot

There are quite a few guys who have been running PI swapped cars @ 10.3 cr and 9/10 lbs of boost on the stock internals with out issue.
If you are forged then you are more than fine but not sure at what point you would need to up the octane.
