Subject: Re: what is meant by over revving an engine? by bogus on 2009/9/21 3:15:31 over revving is usually going to damage valves first. What happens is that the valve train is moving so fast that the valve can't close. It's called "valve float" and it's potentially bad. Next up is the piston hitting the partually opened valve... see where this is going? I would put in a better tach and make sure your rev limiter is accurate. |
