XRAY - Model racing cars

Hi is there any way to get more rpm from a motor I need it to rev higher
Should I try a new pipe maybe a short one on my novarossi p5

Please help Ben

Different pipe can make a big difference.
More head shims will get you more RPM.
Turbo head button.
Larger carb restrictor.
More nitro in fuel.

All of these should net more top end/rpm.

ok thanks Rocco do you know if a novarossi p5 turbo buttom head is a direct bolt on
i will try and extra copper shim also

You should be able to find a head button to directly bolt on to your motor. Contact your local Novarossi distributor for part number info.
