Default compression ration ?

Hey fellas,

What compression ratio are y'all running w/ your forged and built motors? In other words what is the best compression ratio to run w/ a 408 and say a Procharger F1? I was thinkin' about going the turbo route, but am a little hesitant about heat issues.

I'm currently getting my motor refreshed and am planning to get back into FI later next year. I'm currently running high compression (11.1) for nitrous, but I can save some cash if I swap out my pistons now.....

Thanks for any input. I need to see what 800 rwhp feels like......

8.5:1 should be fine.

The lower the CR, the more boost you'll need to make up for it.
