^ that's the 606 twin rotor snowmobile engine. They banned it from being produced because it got so hot the plastic "hood" engine cover would melt... DURING WINTER RACES! hahah.

^page 10 & 11 of the PDF- In some Mercedes models, the seat belt retractors are wankel's that spin by a compressed air charge.

This is sick... Any more info on this jetski?

how about...Wacky and his rotaries :lol::lol::lol::lol::lol:

man I gotta build a jetski I had no idea you put 13b in there. how does the cooling work?
do you just run lake or ocean water in to the coolant?

I was at a jet ski shop who machine their own high performance engines from billet, and they run a water to water heat exchanger that sits in the jet stream of the propulsion jet. This way they could just run coolant and never worry about flushing the engine after a ride or race. That's how I'd go about doing the cooling part atleast

Wacky, I'm waiting to see you on a pair of rotary roller skates:lol::lol::lol:

ahhh cool!!! thanks! I guess you could mount a small oil cooler there too. Now I just need to find a used jetski

Well landon go the wheels in motion. Im building a CRG shifter kart with a sachs 303 im going to smooth out the ports and maybe turbo it with a small turbo later. By the looks of the video it will be as fast or faster than it was when i had a rotax 125 engine on it.

i think you have a little misfire there :D

Wow this thing is wicked, I love the way it sound 20b baby, nice job to the builder.:icon_tup:

I want one of these,,is the diff in this mower and Mazda diff narrowed anyway this thing is bad ass....:icon_tup:
