how much u figure the cfm of air ur moving at say, 15psi? just seeing if what i'm currently running will suffice or need to get one that flows more.

 

what are you trying to do? turbo your car? as far as the cfm goes it all depends on the turbo and so on what size trip and the rest. I have a boost prepped holley 650 if you are interested.

 

actually i'm wanting to try an edelbrock and was wondering weather to stay with a 600 or go to 650. but the going turbo part goes, i'm probably still going to wait til i get my fi setup on it. i'm still in the research phase of the whole thing.

 

I hear good things about edelbrock carbs just them staying adjusted and not needing too much tinkering. Given you have a street port 13b I would definitively recommend going with the 650cfm those things can sucks some serious air down at the top end.
