VERY seriously considering installing a couple brand new 3.3 Whipples with moac on my 500 efi motors. They said 780 to 800 hp all done. I'm running 30p bravos @ 81mph right now all stock. Im looking for advise on props from anyone who may have same set up? AND what your getting for MPH all said and done? The guy at Whipple said usually go up +4. Thanks for the input guys. I'm new to this.

I have a keen interest on this,i am also searching for this info on a different fountain. From what i understand, generally the weekest point of this set up will be the drives. Assuming you have XR bravo 1s, you made need to change your ratio, 30p is getting up there. If you going to change ratios you might as well go to surface drives. they should give 5-10mph gain on top.

I shouldn't have said all stock. the motors are stock. Drives are upgraded bravos with imco lowers. From what im told they should handle the power.

An IMCO SCX upper would be a better choice than a Bravo 1 / XR with 750-800 hp........with the correct coupler you can still run the SC lowers you have

Roger that. Thanks. Looking for some prop help from someone with similar set up.
