As the timing is retarded even further in the combustion cycle process, the exhaust valve will open and combustion of the gas and air may even occur in the exhaust manifold itself, causing pressure and heat to increase even further in exhaust manifold and build even more boost pressure. Pick an RPM where you believe your motor makes peak torque. Community Forum Software by IP.Board 3.4.8Licensed to: VerticalScope Inc. made my first test runs with my new turbo setup on sunday and its hitting the rev limiter pretty early. i hope a spark cutoff as a fuel cutoff would be bad news on a turbo setup......
