Default 800xc with 800cc ves jugs??

hi guys im building a freestyle jetski! an i have a 777cc polaris octane motor. i hear this is the same motor as the 800xc with a different head.
could i put the VES jugs an head on the cases? how much more power does the VES give?
how do the power valves work? gas? electric?
i am trying to get as much lowend power as i can!

thanks i can get part numbers off my motor if that helps?

the ves will help bottom end hp and gas milage, they operate by cylinder pressure.

Whoa whoa whoa, why in the name of god would you want to alter the Octane? That ski is as bad ass as they come dude. Anyways... a sled engine is meant to operate at HIGH RPM, with max torque in the 7000-9000 range. A ski has totally different porting and is designed for torque in the 3000-5000 range. Porting is completely different between sled and ski engines is my point.

Now, the lower end may be identical - pistons and head my be the same - but I really really doubt the cylinders are. What are the part #'s on the ones you have?

Don't the WC engines have different cooling designs around the cylinders? I know the 1050/1200 engines have coolant passages right next to the exhaust. I also doubt that the 777 Octane engine is the same as the xc800 because the snowmobile engine is 799cc

One final word, stay away from PSI, if you ever have any problems you're going to be SOL as Bruce will NOT help you.
