How would you build a low 10’s street car

A boosted car should be in the 8's for compression...

Turbos have a lag and will handicap you off the line... Superchargers don't have the lag...

I want some of what you're smoking.... View attachment 1715381832
I would give you whatever I’m smoking if that was the case but I don’t smoke lol nor do I drink just a guy wanting to learn more about cars and engine builds only reason I said 2.91’s was for highway cruising, I’ve heard 7lbs of boost can double hp was thinking I could run up to 10 and still be okay maybe do it on e-85 to keep from detonation and keeping the higher cr to get my *** off the line and have the turbo put the power down from there
