I'm running a 07 rage with the 496Ho, bravo 1 X and a labbed 27 4 blade and running 75 gps. I'm sure with a 500 efi the #'s would look a lot better.
For the drive I'm sure you have a Bravo X on there but check into the HP ratings with going with a higher Hp motor. What was/happened to previous motor?
bravo 1 400 hp
bravo 1 X 425 hp
Bravo 1 XR 600 hp.
Got any pics?
