Talking Re: eureka, I got it running dyno to follow
Area in a hole is = Pi x R squared

R = 1/2 diameter

74 mm hole area is equal to 74/2 = 37 squared x Pi

R is 1/2 the diameter of 74, therefore it is = 37

*********************

37 x 37 = 1369

Two holes are twice (1369), thus 2 x 1369 = 2738

square root of 2738 = 52.325

52.325 is the equivalent radius thus the diameter is 2 x 52.325 = 104.7

*************************

I did not use Pi and then divide by PI so please forgive my short math hand.

two 74 mm TB's are equal in area to one of 104mm.

104 is bigger than most TB's on the market. ITs right there with the 5.7 dodge hemi!!!!!!!!!!!!


Sorry for the homework........W DY
