It should work well. I have seen several Raptors with dual 39mm fcr's, thats 78mm of cfm@7800rpm to 9500rpm and it loves it....

I think if you build some kind velosity effect with the new intake track just as it inter's the throat of the cylinder head, just an idea!!!

Two 39mm's are not the same as one 78mm.

Pi x (39:2)???? = 1195mm???? -> 1195 x 2 = 2390mm????

Pi x (78:2)???? = 4778mm????

As you can see two 39mm carbs are not the same as one 78mm carb.

Two 39mm carbs are the same as : 2390 : Pi = 760,76 ---> The root of 760,76 = 27,58 ----> 27,58 x 2 = 55,16mm

So, two 39mm carbs are about the same as one 55mm carb.

^^^^^What did he say?^^^^^LOL

C27,

Make sure you are firmly attached to the seat, because when you crank that big mama open there will be enough velocity to suck your skinny body right into the motor! Wistech is not going in after you either! LOL!

OOOOOoooooOOOOO I love it when i can hear the intake at WFO or even the whistle it makes at just above idle when cruising.
