Hi there im really interested to know how speedwerx got around to get a supercharger working so well on a 2 stroke despite the theory saying they would blow all air/fuel mixture right out.

Anyone knows anything?

And for those who bought the kit is the secret in the pipe somehow?

When ever 99% of people say something can't be done, someone figures it out, haha. Honestly, with the tech that we have today, makes perfect sense. Speedwerx knows their $hit! I've thought that a modern supercharger might actually work better than a turbo on a high strung 2 stroke. 2 strokes like tuned exhaust, a turbo has to mess up the exhaust flow somewhat. Superchargers have some advantages over turbos, also it's nice not to have a red hot contraption in a tiny space like a snow sled. Also, folks that think superchargers aren't efficient, friend of mine drives a 840 hp Dodge Demon, brags that he gets almost 30 mpg.....:grin

Yeah but im only interested in the technical solution that made it happen since it contradicts the base of 2 stroke engine theory. So you guys that have a supercharger on your 2 stroke whats the secret ? what have u discovered ?

you mean superchargers or turbos? Because superchargers don't contradicts 2 stroke engine theory at all, they add a certain air charge to the crank per crank revolution based on how open the throttle-body restriction is, so you basically jet it like a normal engine where the crank vacuum pulls in the air charge. Turbos are a little more fiddly but as long as the guy riding has some mechanical empathy even a carbed turbo can run strong (you basically try to run it less jerky on the throttle because every time you come off the throttle completely you lose boost and thus your pipe is suddenly too small until you get back on boost again). The expansion pipe on turbos and compressors is simply made as if the engine is bigger, so if you're running 30% higher air density on a 1000cc twin two stroke your pipe will be tuned for roughly a 1200-1400cc twin two stroke (dependent on how efficient the crank is (more efficient cranks will have narrower power bands but higher peak power)).
