Turbo loaded two stroke?

[pyromaniac]

How about putting a aerocharger on a 2-stroke motocross? Have you seen any? If not why? if they work on snowmobiles shouldnt they work on dirtbikes?

My guess is that a turbo charger would not work on a 2-stroke dirtbike, but a supercharger would ...at least i cant find any reason why it wouldnt. i think the backpressure caused by the turbo would mess things up.

A turbo on a two-stroke dirtbike just isn't feasible for a variety of reasons. First and foremost is the amount of heat that would have to be dealt with. A two-stroke engine fires on every revolution, giving the piston a very short time interval in which to cool. The engineering and complexity required to make the engine reliable and rideable just isn't worth the effort.

The compression would also probably have to be lowered to allow the engine to survive beyond the initial warm-up period without a melt-down, resulting in some serious turbo-lag.

Not the least of the problems would be packaging the tubo-charger and all the neccessary plumbing and fuel delivery systems (turbo engines require lots of fuel when on the boost to prevent severe detonation and engine failure). Modern dirt bikes are a mavelous piece of engineeing and design, very compact and light weight. Adding all the complicated plumbing, controls, and weight of a turbo-charging assembly would be a step backwards, in my opinion.

What about the A/F mixture? Hard to regulate if you ask me without some kind of engine management. Imagine if you wetn to lean just once? It would get expensive quick.

I would think that the non-constant throttle position would make it hard for the turbo or supercharger to spool up. I know that with sleds you get on the gas and hold it, the clutches do all the work. This is why a turbo or supercharger works better on this two-stroke application. Just my thoughts.
