[Healeys] which carb set up?

[Greg Lemon]

Area = pi *r * r  (pi times radius squared)

1" x 1" (radius squared) x 3.14 (pi) x 2 (carbs) =  6.28" sq. in. for double 
2" carbs

.75" X 75" x 3.14 x 3 = 5.30" sq. in. for triple 1,5" carbs

This is of course the theoritical "maximum pipe" for airflow, actual will 
also be affected by the throttle plate and such, but theortically the double 
2 inchers can flow almost 20% more air.  Of course the triples give you a 
straighter shot to the ports, I suppose there is a reason older high 
performance engines like Ferrari and such often had an intake carb barrel 
for each intake port.

But it doesn't look like you lose anything, and may actually gain, with the 
double carb set up.

Maybe some of the racer boys can pop in with some real world experience.
