Just guessing......but if a modified 3rd gen with good turbos can make 400-450 hp? I'd say around 600-700 cfm.

no way on the 600 to 700 cfm ... sorry. A much better guess would be 500cfm and that is probably pushing it.

I would guess they combine for about 500 cfm at 10psi. The fd makes about 1hp per 1.8 cfm according to Turbo Specialties.

hmmm, that would be 460 cfm then, correct? Also, it is standard for cfm to be stated "at 15psi" even if stock boost pressure is less than that. Can anyone confirm or refute this number?

BTW, thanks for the replies
