Nice model 4150 Holley in the background. What do those fibre baseplates cost and how thick are they ? I might just be able to get that on under our limited stockcar rules.

CFM to the engine after the carb or laminar flow improvement is the term,I think.This is just my opinion no actuall tests here on my end.If you have turbulent flow under the carb which disrupts the smooth flow of air ,you will see less hp ,if you install a spacer and improve this turbulent flow and make it more smooth you will see more hp,not sure if the cfm thru the carb improves enuff to go over 100 percent efficiency,stands to reason that you just improved the flow and now your getting 95 instead of 90 percent efficiency.? sounds logical ,..but so did Hitler to the germans soo I am not sure. But it sure sounds like good logic. .
