Hello People

All blown-injected motors are required to have blower restraints. All blown fuel motors are required to utilize an SFI 14-2 approved restraining device. All blown alcohol motors will be required to utilize an SFI 14-1 approved restraining device.
All blown motors utilizing a screw type blower are required to utilize an SFI 14.21 approved restraining device regardless of type of fuel used.

Be sure you are compliant with the safety rules. The SFI 14.21 certification restraint is a blower bag and restraints that are inspected / recertified every two year.

I heard that the tech inspectors are to be more vigilant on safety, just a heads up if want to pass inspection to race. :)Unsure

Willis,

Here is the complete rule from the rule book. Nothing new has been added or changed recently.


1. All blown-injected motors are required to have blower restraints. All blown fuel motors are required to utilize an SFI 14-2 approved restraining device. All blown alcohol motors will be required to utilize an SFI 14-1 approved restraining device. All blown motors utilizing a screw type blower are required to utilize an SFI 14.21 approved restraining device regardless of type of fuel used. All screw type blowers are restricted to the amount of overdrive used and must meet SFI spec 34.1 construction standards. For construction standards and overdrive percentages, contact the Tech Department. This restraining device must be in place at all times when the motor is running.
2. All blown, injected, or fuel boats must have a fuel shut off valve controllable from along side or in front of driver. The valve shall be located between the main fuel pump and the injectors.
