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.
