Supercharged 2-Stroke
- Thread starter SuperN8
- Start date
Two stroke deisels usually use a supercharger as a scavenging pump and some use a turbocharger along with a scavenging pump. But i think they use exhaust valves not exhaust ports. This way they controll overlap.
The one in the pic has no valves, just ports and the turbo feeds the intake manifold.

Yeah that was me but it was just a joke I never planned on running it. Just a kit I had for an old 650 and had a single carb manifold adaptor.Clearly this has been covered before, my mistake for kicking it up again

@waxhead ski?
just curious, running a supercharger would you still have to use a expansion chambered pipe, since there will always be positive crankcase pressure to blow spent gases out of cylinders?
The turbos are mounted after
The pipe... On the stinger. You'd make no power mounting it on the manifold. Also, from being in both sled engines and pwc, it seems that pwc has more smaller ports than a sled engine. Guys have had great success turboing sleds that have carbs. I think it had a lot to do with how much boost you push, and when your exhaust port closes. The 650 was behind its time to accept the forced induction of a supercharger and actually be able to use it

Does anyone know if a two stroke would still generate enough pulse to run a fuel pump under positive pressure? It seems like the more pressure you had, the weaker the pulse would be. I know that it already has 14.7psi on it because of atmospheric pressure (and it works) just wondering how much it would change with 6-7 psi more.
