The Cub cylinder kits are recommended for use with race gas. Redline Racing has tested 4mm motors at well over 100HP on gas with a wide spread of power. These are great motors for the daily duner.
On alcohol, the 4mm 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 Cub cylinder engine moves up in the RPM range compared to a Serval cylinder engine.
Pricing is the same for all Cub cylinder kits.
