Relationship between compression ratio and streetability???

My suggestion is 9-1 with about 10-12lbs for the street. If you want more boost, drop down to 8.5-1, but no lower. Any lower and the response on the street gets sluggish. You gotta remember one thing, just putting around on the street isnt going to build alot of boost. The small opening of the throttle blades will not let much thru. you can run 20lbs of boost if you want to on the street with 87 oct gas, as long as you dont turn much rpm(like shifting at 3000).
