660 intake & HP

I'm rebuilding my 727 that had a cracked case. I would like to get every bet of HP out of it but yet have it be relieable so I am asking what intake would be the best. Right now I'm running a billet adapter W/ a K&N, led off,but still in the air box

Reliable 727?


I would ditch the bottom portion of the box and run the longer(about 12") k&n. That is what i had on my first bored rhino, worked great but it was only a 686 w/ 13 to 1.

The k&n procharger system works well too imo.

Don't use a big word when a diminutive one will suffice. Dont make me go all "tattoo" on your ass.

John @ The Pro Shop maintains the motor. He has worked his magic on this motor for over 2yrs. we r thinking of stoking it and going to a 720. But lets stay on course: intakes!!!

the AFE keeps the air cooler than a k&n and flows better it dose have a box but the box dose not restricted the flow but dose keep the heat out..john likes the new k&n but I stayed with my AFE when he built mine he has my dino there compare with another build like mine with the k&n then there is no guessing

I'll talk to John and see what he has to say. & see if he has your dyno records so I can see for myself.
