Default If our TBs were rated by CFM.....

If our TBs were rated by CFM like a carb or TB generally is, what would a LS1 75mm TB flow in CFM? 90mm?

Thanks, Shawn

I would say that a nonported stock TB would flow 780 or so and a 90mm(being a nice aftermarket one) would go 1000-1200cfm.

I would say about 100cfm over stock, it is still a 75mm- just a true 75 unlike they are unported. The TB may have a 75mm blade in it from GM but the opening is only 72mm or so
