Big Gun Rev Boxes

Big Gun Statement:

All Big Gun Rev Boxes are designed to enhance the rev limiter from 1,000 rpm on most models to 3,000 rpm on others.  By allowing the RPM of the machine to go over its normal low setting allows the engines to build the actual horsepower that they were designed for.  By moving the rev limit up we have been able to pick up 1-3hp depending on the model.

We keep in mind that by eliminating the rev limiter this would only cause problems with bent valves and damaged motors this is why we have chosen to keep the rev limiter in place but to move it into a higher and still safe level of RPM.  The other nice benefit of the Big Gun Rev Boxes is that we have advanced the timing allowing the motor to rev and pull stronger.
