Other Supercharged or turbo two stroke?!?!?!?!?!?!

Has anyone ever put a turbo on a two stroke or a super charger? Wanted to build one for a college product. Let me know your ideas I have some ideas just wanted to know what your guys think.

Its diffiicult to set up on a 2 stroke because a soon as you have positive pressure on your intake air/fuel mix right out the exhaust port so it would make it waste a lot of fuel and be very hard to tune. I have seen several snowmoible 2 stroke turbo kits out there and I am not sure how the success of those kits are but I think it would be really hard to do in a jet ski. The older supercharger kits for the kawasaki 650sx I have read did not work out very well.

Study this picture and you will realize why forced induction does not work for 2 strokes. The pipe acts as the power-adder.

JETSKIHORDER18 your biggest problem running a turbo in a jetski is getting rid of the heat. Goodluck

If you install a turbo on a 2 stroke you do not to have an expansion chamber - we can use a straight pipe/tube, right? Or am I mistaken?

About heat: could liquid jacketing solve some of this issue?

eerie,, the diagram is not a reed induction, but the rotary motors will work best since the rotary valve closes off the cylinder like the valves in a 4 stroke..

the mrd type system still has the seal issues that a carb has, but would work well. now mrd on draw through would be the shiz. just need to make a single mrd or run a single throttle body from a 4 stroke couch.

On a properly set up turbo the ratio between your intake and exhaust pressures is very close to equal. Much like it is when naturally aspirated. So at least for a turbo, loosing the air fuel charge out the exhaust would not be an issue.

either that or fuelie like mrd.
and that's a johnny'o 650 sx system adapted to a sj.you need to overdrive the blower for increased cid. wax.
It was only ever put on there as a joke. I was never going to run it.
I had a whole lot of single carb conversion manifolds and the adaptor plate allowed it to be bolted on
 
once tuned in they worked pretty well.gobs of torque allowed a steeper impeller and kept the revs low.

you should try it wax.
