Choosing the right engine combination for your race team.

The following questions need to be reviewed in detail when deciding which engine combination or options makes the most sense for you and your race team.

  • Budget of your racing program
  • Type of track and track conditions you experience on a typical race weekend
  • Desired RPM range you prefer to run
  • Fuel delivery system on your race car
  • Sanctioning body or claim rules
  • Weekly racing, traveling series, or special events
  • Oil cooler system recommended

Upgrading your valve train or short block components

Internal component upgrades will not specifically improve the horsepower/torque output of your engine, but plays a significant role in improving the reliability, longevity, and RPM limits ofyour engine.

Oil temp demands of your engine

Conventional engine oils begin to break down at 260 degrees, while synthetic oils begin to break down at 300 degrees. Once the oil reached this point, it will never return to it's original level of protection. Oil break down will cause bearing and component failure. Oil coolers can help reduce operating temos up to 60 degrees.

 Fuel Delivery Components

Given the demands put on today's racing engines, we require that modifieds running alcohol use a belt drive fuel pump. Mechanical pumps are sufficient on gas, but do not produce enough fuel volume at RPM to meet performance demands.
