Its not fit for the 5ive, never mind the DBXL.
Engines this size and type its a gimmick and does not work.
Read other threads on it.
Don't waste your money - save for a tuned pipe / engine.

Superchargers on any two stroke is a scam. Don't waste your money.
Actually they are working just not on a rc level speedwerks has them for 2 stroke sleds and all the Turbo'd naysayers are jumping ship it's been a long drawn out process about 5 years but people are happy with them now. I doubt it will ever happen on a rc level but we're there's a will there's a way. On the sleds I think it has a lot to do with the pipe from letting all the charge air going to waste.

A turbo and a supercharger are two totally different things. Their method of operation is completely different.
I would like to see how they have it set up. They might call it a turbo, but a normal turbo is useless on a two stroke. A normal turbo would just hurt a two stroke because it re burns a portion of the exhaust gasses to "boost power." And it would also disrupt the reverberation in the expansion chamber of the exhaust pipe. [emoji848] they might call it a turbo, but I'm sure it's totally different then a normal one.
The ones I've seen for rc are a complete waste of money.

Here is a good video. Keep in mind, we use crank case induction two strokes.

As I suspected, these turbos are completely different and methods are different then a normal turbo. They are basically redirecting more exhaust gases back into the engine. A regular two stroke is already "supercharging." This system is taking that exhaust that doesn't get reverberated back through a tuned exhaust and shooting it back into the engine. Notice they had to create variable pitch fins in the turbo so as to not disrupt the reverberation of exhaust back into the engine. A normal turbo would just suck all the charge out of the engine. So yes it is possible, but it's not a normal turbo system, As I suspected.

Heat would kill something like this on an rc. Our engine run at way higher rpms and we don't have snow to help cool the system like this one.
We have gotten way off topic with turbos, but I hope I've helped explain why a supercharger won't increase performance on our two stroke rc engines.

This is a real supercharged two stroke.......

Don't believe everything you read it does work with proper pipe mods piston port no, reed yes.
I know the difference between a turbo and supercharger I have a turbo'd sled and yes turbos are also very effective on two strokes so crawl out of your igloo and look around before you preach :badair: .
Besides the aerojunk link you posted it's just another turbo, has nothing to do with a supercharger. Like I said in the rc world at this time no but their are reed and rotary valved supercharged two strokes that are actually working making great hp and especially so are turbo's just remember were there's a will there's a way and someday you may be proved wrong in the rc world also. Take a look at the 3d printers going around they print all metal materials in the high end printer market, you could see miniature rc turbos someday that will work on the reed engines :w00t:.

Our original topic was the superchargers for the 1/5 scale two strokes. Those are pointless. These modified snowmobile kits and how they are set up obviously work with the right engineering. We don't have these set ups for rc and putting one on the current design won't work.
I know the Army has poopy living conditions sometimes, but we have actual houses now no igloos. Lol

No turbocharger or supercharger will work on these style of motors
Why well it's all about port timing and the fact is the intake port closes before the exhaust with that nothing will work to force air in to the motor to raze compression
Because it just blows through and out the exhaust
On them you can use it as a cleaning charge like a fan blowing in a room
That's why the exhaust is so important on theses motors
