Reply to "Annular vs. Down Leg boosters"

George,

Now comes the fun...you've seen the standard calculation for picking CFM on a carb...I assume that would be the dry measurement? Probably dry if you're saying Demons are the only one that measure wet flow...then I'm assuming Quick Flow and Pro Form(which I read make Quick Flow carbs) measure dry? Also the standard calculation on doesn't compensate for valve lift, duration, port and manifold flow, etc. So its hit and miss.

If you wet flow test a Holley I assume it's cfm drops? So are they really flowing the same if flow tested with the same process on the example below?
Dry flow.......wet flow
750 Holley = 650 Demon
850 Holley = 750 Demon

I see that many are running the 750+ Holley DP on the Pantera? That's the size I assumed I should look for, but the snag comes with annular boosters...do I get an 850 Holley with annualar boosters since the flow is reduced and a 1050 Demon with annular boosters since the Demon is rated wet?
