We all laugh but spinning the front tire to over 10 mph is the only way to deactivate all, and I mean ALL of the rev limiters in the car. The engine went up to about 6,300 rpm and it wasn't stopping, but I decided instead of seeing where the engine cut-out, I just let go of the gas. The car "supposedly" has a fuel cut-off at 6,100 rpm, and it easily went past that, so why risk it?
