Default Re: lower gearing for a cranbrook

Thanks for the reply, I appreciate it. expansion chambers can be a real pain, the distance from the port is critical so that the back pressure wave hits the denser incoming gas and pushes it back in, usually this only happens in a narrow RPM range, you can actually lose power with one.
