Sometimes practical experience counts for more...

By Gerry Proctor - 04/12/2005 3:44:02 PM; IP 207.133.188.254

than theory. You're right, Greg but you don't need equations to prove it. If you use the numbers, a Pro Stock engine could easily get by with just one Dominator. In fact, it would still be considered "overcarbed."

The ideal method is to look for no more than 1.5"/hg pressure drop at WOT at peak VE. I doubt you can get below 3" using the formula.

I know my warmed up 390 runs a whole lot better with a 750 cfm carb on it than the formula's 600 cfm...or less.

This thread, so far...
