I dread to think of the fun of jetting a turbo two stroke

I wonder if it's still running 7 years later...

Doubt it , that's a lot of power and revs for a small crank,
I guess anything more than 11000 rpm would soon see the engine give up

Wouldn't a turbo only work if you could also increase the back pressure of the expansion chamber as by design a 2T engine has both ports open at the same time, so any increase in pressure in the manifold and hence during primary compression at the crank would just blow even more mix into the expansion chamber. You would have to somehow increase the back pressure wave to "stuff" your extra mix back into the cylinder between the inlet and outlet ports closing. I think this would just blow unburnt fuel out of the exhaust and give no more performance.

no this is a strange working it actually increases with more you put in you get more back so its all relative
hard to comprehend but it actually does increase ack pressure on its own maybe a new chamber will help to not sur e on the guess you would have to tweek that also i know you have to reinforce the seals big time for sure
