The Cheetah Cub cylinder packages are recommended for use with race gas. Redline Racing has tested 4mil motors at well over 100HP on race gas with a wide spread of power. These are great motors for the daily duner.

On alcohol, the 4mil Cheetah Cub package will make 115HP with good supporting parts. This engine setup leans towards drag racing. 

These are very reliable with good supporting parts. The power band for a Cheetah Cub cylinder engine moves up in the RPM range compared to a Serval Cub cylinder engine.
