Rev Limiter
Posted: Tue Sep 26, 2017 6:06 pm
Just a quick tale of an incident in my +2 a few weeks ago.
I was about 3 miles out of Beaulieu on an autumn break, and was just about to change up from 3rd to 4th at about 40 mph. Little did I know that the throttle cable had decided to stick partly open while in gear. As soon as I declutched to change up the engine shot up to 6500 rpm in less than a second, and was held there by my sprung-contact rev limiting rotor arm.
If I had not fitted it the revs would have gone up to who knows where, with possible engine failure.
As it happened, I was able to re-engage the clutch with a puff of clutch dust and burning, and was then able to brake the car until the engine stalled at the side of the road. A bit of fiddling about and the throttle cable was freed and there was no damage. Phew!
So I will not be driving without something to limit the revs in future (in the past I have used a standard rotor arm sometimes).
