With the new Engler Stock Throttle Bodies being released at the shootout this year we with the Lonestar 600's were faced with a decision to make. Allow or not. We are a firm believer that once our rules are published we dont change them unless it's a must. This is in our terms is a must. With our neighbors to the north announcing that they are allowing it. We feel its best that we should follow suit. Now before we are shunned for allowing mechanical Injection. One of the biggest reasons for allowing this is for safety. When the motor dies, fuel shuts off. No more feeding the beast when your upside down. Second is give another option for drivers to choose.
The rule will read as follows:
600's:
EFFECTIVE 2019 RACE SEASON: 600 class will be allowed to run Electronic or Mechanical Injectors with a mechanical fuel pump with stock OEM throttle bodies or carbs ONLY will be allowed. No mixing of manufacturers. Must be OEM to engine make. OEM boots only with injection. 600 Carburetors only. No Flat Slides. Stock ECU, PE3-IG2 and PE3-8400 Engine control units are permitted for use with carburetors and Stock Throttle Bodies Fuel Injection. No cones will be allowed. No regular rubber hoses will be allowed. Carbs may have metering rods, jets and springs changed to tune the fuel curve to match your cars requirements.
