Looks like hp on Tuesday

Interesting question on the air flow.

We have done extensive testing comparing a 780 against the t/b and a carb with and without boosters. Would you believe that a carb without the boosters only flows a single digit increase compared to a 780 with the boosters?

. What really helps the 780cfm flow more air than the t/b is that the carb is nearly 3 times the height (counting the air horn) as compared to a 2 inch t/b. The carb, due to its" tunnel design", has the advantage of increased velocity compared to the t/b.

This helps in the atomization of the fuel and gives it a "heavy charge" and that results in almost a 30% increase in the flow/velocity for the 780 carb compared to a "dry" T/B.

Its really elementary physic's.

How'd that sound??
