Real world experience.
They have been dyno'ed and yes they can pull up to 30% with the right fan, standard its 10% ,do your own research, there a few years old, l aint spending 7 hours finding old posts for the details, just buy one. They work.
Have you actually seen any real proof of ANY nitro engines ? Is that common ? NO.
Traxxas claim over 1 HP from the TRX, like to see you proove that, ppfftt.....Cen recon they get 4HP out of one of there engines...bs.......PROOF and claims are different l agree, but dun get niggly with me over superchargers, had this debate a few yaers ago, is why l bought one, after arguing they cannot work, i was forced to EATMYOWNWORDS.
So go eat yours.
Or buy one and we will debate it if yours doesnt work , ok ?
Before that, you have no argument saying, what you did.
But by all means look into them, there not worth the power per buck, but they are bling noise and look the part.
The numbers were originally posted on there sight. RB.
Independant testers gained far more with exhaust modifications and induction fan changes.
If you understand how a nitro engine works, it becomes common sence that they do actually work.
The debate is how much boost they can give.
At 10% on a nitro engine that revs to 30 or 40 thousand RPM, if you cant figure that the scavenging is going to increase air flow, and lubrication, your missing a few l recon.

They can be fiddly at first to tune.
