Boosted 2 Stoke

those are trail tech lights.


but how would you turn the supercharger?

A supercharger is a lot more feasible for a two stroke than a turbocharger really because of the importance of the performance of the pipe/silencer for two strokes as they don't play AS critical of a role for 4 strokes. You would just have to fab up a pulley system to your liking of boost off the crank with a SC.
 
How do you like them? And where can I pick some up?

Im really wanting to drag it and every now and then ride it up our private road and pods the neighbors off for short periods of time lol...and just to see if I can make it work

What pulleys?.....that's something you will have to figure out. I:I My guess is you would have to fab an extension of the crank to run outside the bike(already a biotch in itself), then figure out a pulley network on a fabbed plate on the side of the bike to attach pulleys to before attaching to the SC.....assuming you could ever find a supercharger that would work....which I'll just guess that you can't, so the SCer would have to be custom fabbed too. Figuring out boost is kind of a pain and even I don't know how to do it from a raw plan with nothing to guage off of. A person in hi-po might have a better idea of how to do it, but I'd probably just plug and play until I got something satisfactory.........then it would go boom 5 seconds later. :D
 
also for the trail techs, they are not cheap new, like $350 for the stock location lights for a banshee.
you can get the handlebar mount ones for around 50-60 right now at motosport.com
 
As for turning the sc I can modify the end of the crank at the stator to accept a interior threaded shaft, cut in a key way for the sprocket. Same as any non supercharged vehicle, they don't come from the factory with a spot for all the components to fit in there just in case you ever want to add one...the kit provides all the needed pieces...ill just have to make my own pieces
 
I had batted the idea around in my head before deciding that a modified blaster can put down enough power without it...

Get a fly wheel puller and chuck it into a lathe and bore the center of it out until the flywheel nut will pass through and down into it. Put a thin washer in and thread the flywheel puller down into the flywheel and then the flywheel nut down to tighten the assembly up. Once you're sticking outside the stator case, you can belt drive it up behind the reed mounting surface and make an adaptor plate to the reed mounting surface to bolt the super charger on. A small cog drive belt off of a piece of machinery and a cog drive pulley made to fit on the outside of the flywheel puller tool and you've got a belt driven supercharger using a draw through carburetor.

If you were really bored and liked fancy stuff, you could use the stator cover as a template and cut a custom belt cover out of aluminum and make a little housing for it.

Oh I bet it's harder than you think. :D I'm interested in what kind of turbo they are using for their setup there. Might be more beneficial just to run without a silencer at that point.

not really. it comes down to how much money you have.
you need a good pipe. one that will allow the engine to rev up and also turn the turbo.
you need the correct turbo, both the size and the compression wheel for your app.
there is a company that can make any quad EFI. once you get efi it isn't that hard anymore.
just need some strong reeds, they make steel lined reeds
 
It's a roots blower. Perhaps a helix but it doesn't look like it... It looks like the inlet and outlet are on the sides straight in and straight out.

It has plumbing instead of being made into the intake tract like a supercharger made to go on a car.
 
Again its not a belt driven supercharger. Chain driven and it mounts in front of the motor. Good setup and can get a used one from anywhere between 4-500 bucks

Carbon Fiber reeds are strong enough.....you just need a larger cage and maybe get slightly thicker carbon fiber. Pipes aren't a huge deal on 2 strokes as they all run at powerbands in higher RPMS regardless. Biggest problem would be idling and low speed performance. You would need to match an EFI that is mapped correctly for that individual bike setup.......which is always a fun task to determine how to map it. Finding a sufficient turbo is a bit of a painstaking task as you want something that stays within your limits of boost and can spool effectively coming out of a pipe with a expansion chamber like 2 stroke quads have.....if not....unknown amounts of backpressure will remain in the pipe stopping you in your tracks from the get go as you aren't flowing enough exhaust. Doing this from a known point is quite easy.....doing it on a raw plan on a bike with little info is a little tougher. I'm willing to bet none of these guys with turboed and SCed setups really have an "ideal" setup. Yea...it functions.....yea it's fast....but it doesn't quite work in congruence with each other in a way to maximize reliability and performance. Stuff like that takes a lot of trial and error and R&D work with tools that I'm guessing they don't have.
 
I know lol im just making sure everyone knows its not a belt though. If you guys actually saw one on a kart you'd understand the workings of it...they make a world of difference in karting. But that's a totally different ball game
