800 etec sled twin is 175hp I think buts thats with a ex valves and single chamber, sea doos have less power, no ex valves so more inline with an outboard but the jet still makes life easier for them.

Back --WAY back--when I was building custom expansion chambers, a guy brought me his 440 Yamaha with one request: Make that sucker fly! It seems he had a neighbor's hot Artic Cat was just a bit faster, and that was intolerable!
The Yammy had a two into one expansion chamber (factory) that ended in a huge muffler. I made him two chambers for it with stinger mufflers, and I made them for top end power only. The result was it was a dog getting "on plane" (so to speak), but when that sucker hit the power band---whooh doggie! He blew that guy's cowling off, but it took a ton of spring work on the clutch to get it to rev a lot higher before ratioing up.
I also built a triple set of chambers for a guy with a "water Buffalo" (750 Suzuki) road bike that he made into a chopper. It was a real challenge to get all three nestled in there without them dragging on the road, but... Sounded insane as he roared off!
Ah, memories...
