On this video, when they start racing the chap in the MK3 MX5 is practically bouncing off the limiter on every change he can.. Would that not be bad for the engine?

And whilst your watching the video, thats some pretty impressive driving considering the conditions biggrin

surely thats the idea of a rev limiter? to limit the revs to prevent damaging the engine?

So bouncing off it is okay? Obviously not on a drive to the shops will you be limiting it, but now and then its fine?

I've never had the limiter in mine, I just thought it'd not be good for the engine.

Let's put it this way... the longevity of the engine will suffer if he continues to do that, but it won't go pop as he's hitting the limit the manufacturer has set.

That's why you should never buy an ex-hire car, because as we all know, they are the fastest cars in the world.

Removing it and then forgetting about it is a big no no. wink

It's there for a reason, if it would dangerous there would be a pre-rev limiter...limiter biggrin

And one more thing - in most of the standard cars there's absolutely no benefit from revving the engine so high, the best spot for changing the gear is below it anyway.

yeh, if hitting the rev limiter was harmful for the engine don't you think manufacturers would limit the revs to like 3k? obviously if you drove on the limiter all the time your engine would wear faster, but its not harmful to hit the limiter

I touch the limiter just about every time I drive my car.

Thanks very much, yeah I usually change before the limiter anyway.. Only found it once in my old car when it was wet and not very good tyres.. Not in the '5 yet.

Watch the video for fun driving anyway! biggrin

It's very difficult to keep off the limiter when going sideways in the wet like that- the sudden drop in traction from tyres gripping to tyres sliding tends to leave you with too much throttle and it's not easy to back off enough to get off the limiter but stay sliding.

Shouldn't do much harm though. Limiters are made to be hit!

Why would it do any harm, if it did they wouldn't build it so it could bounce off the limiter at those rpm.

I'm a bit confused here chaps. The limiter in my impreza is just past the redline. Shirley taking it into the red is baaad, but if the limiter is set there then is it okay to explore? I never go into the red zone but I suppose with a scoob there's a degree of driver awareness/sympathy involved.

Pop some of this in your engine, and you can rev the nuts off it until the end of time...



Never need to change you oil... ever again too rofl

The redline gives you something to aim at, and the limiter catches you when you miss it. Would be very frustrating if the limiter was lower or dead-on the redline as you wold be hitting it willy-nilly.
