CMB RS 101 Speed Car (16.5cc Nitro engine)

Hi

I'm also making an IC speed car. Here is a short video of the dynamic tuned pipe mechanism

Instead of fitting a 4 speed gearbox I have installed a dynamic pipe tuning system. This gives me max torque at 15,000 rpm at 330mm and max torque at 26,500 rpm at 285mm.

I'll test it on the engine when I have the rest of the car together

Cheers

nice, simple and clever, now all you need to do is electronically link it to rpm for the ultimate wide powerband, keeping the torque high all the way from 15 to 26.5! does it affect your fuel tank pressure or mixture at all??
