This helps the metal bond to the cylinder and is more durable.

  • Car blend nitromethane fuel with 10-30% nitromethane content, 16% nitro content recommended as starting point

  • Most of the fuels we carry meet or exceed the lubricant content required for optimum performance and maximum engine life. In the past, the conventional lubricant content used in fuel was 18%. But with new advanced technologies, fuels like Red Alert and O'Donnell for example, have a better quality of lubricants even though the percentages of lubricant content are lower. These high-tech lubricants provide exceptional cooling and protection.


  • Some notes on Slide Valve and Rotary Carburetors:

  • Rotary Carbs offer a larger response in the middle of the power band. This works well for off-road applications when throttle response must be varied.

  • Slide Valve Carbs provide greater response at the beginning and end of the power band. This works well for on-road and racing applications for fast take-offs and high speed.
