Does anyone know if there is a company that makes a 2 stroke supercharger for the hy engine?

My recommendation is to first understand the 2 stroke engine's in and out first before thinking about super charger.. LOLSheppy 800 said:Wasn't sure. Thank you for the info
IMO 3 to 3.5 for the stocker. Others may disagree. For those who have built or replaced it with a modded engine it is a night and day difference over stock.Roughly how much h.p. does the 30cc engine put out with a dominator pipe and wt990 carb. ?
That explanation sums it up... 30cc its one cyclinder, both ports open same time, more pressure just blows it out faster...TerraKill said:superchargers and turbos wont work on 2-strokers as both ports are open at the same time so it cannot hold any boost created by a supercharger, however if you did fit one they do smoothen out the powerband and stops lowend bogging ive ran one of them gimik superchargers on my savage before and thats all it did, i had to try it was a steal on ebay, but i took it off for 2 reasons,
im pritty sure it was achally staving my engine of air at high end rpms (i cant prove it tho, could of been a number of things)
and its just a pita to work around, and would of easly broken it with a bad crash
ohh i forgot to mention, they increase fuel consumption by like 50% as most of it was just being blown out the exhaust
heres an explination from a user on a motorbike forum i use, he explains it very well
"Possible but difficult; on a 2-stroke, the exhaust port is open while the fuel-air mixture is forced into the cylinder. With a turbo you would blow a lot of the new charge out the exhaust pipe. Besides the horrendous fuel consumption there would be little pressure increase and HP gain. The exhaust could be tuned to provide an immense amount of backpressure enabling use of the more dense charge, but the engine would only run well within a very small RPM range."
What you are leaving out is that the Detroit engines are indeed 2-strokes but they have exhaust valves unlike the engines in our RC cars. I work on many different diesel engines including Detroits on a daily basis. (Mechanic. US Army. Afghanistan)Bigboyztoys said:I've been considering a supercharger for the stock 30cc by redcat. I've read so many negative posts regarding the actual advantages. And several people quote the same thing over and over and over. "The physics this and the physics that". And "you can't super charge a two stroke" my cousin's daddy's sisters boyfriend said so. Fact, you can supercharge a two stroke. Detroit 671,471,371. built by GM came asperated in three ways. There are many configurations of that motor. Also, if you wanted even more power you could order a turbo/supercharged version. Facts;Detroit 671 is a two stroke. Fact; 671 Detroit was a very reliable engine. Fact. It performed much better than the naturally aspirated version. Fact; the engine was bullet proof but loud. Fact; you could run the engine in both directions with an oil pump mod.. Fact; the supercharged 671 is being used in an array of applications today right now, and the engine is over. 40 years old. So if a supercharger and a turbo work on a v6 two stroke why won't it run on a 30cc?
