They make a kit to mount 2 separate Nitro motors side by side.
also RD innovation makes a super charger that will add up to about 27% power/boost.
Why do people think that bigger is alwas better?
That HPI motor may have torque but no top RPM. 3 speed sounds nice but is heavy, that is why all competition cars are runnen 2 speeds which is with competition engines more than enough. And why would you use any crappy supercharger with vague powe gain claims if you can get more air with just more nitro in the fuel?
And why not modify the engine?
If you give advise then please, know what you are talking about.
