Over-Revved, Am I gonna be ok ?????

Wow. Good thing I had an RX-7 when I pegged it regularly since reving was so quick. Buzzer went off all the time. I think Z can handle it too.

I'm pretty sure down shifting from the top of third to second it would bring you to over 10K rpm.

I listened (at a banquette dinner) to a professional race driver Johannes van Overbeek, complain about his team mate over revving his Porsche to 11K to assist breaking. The crew chief said so. If it breaks we (Porsche) will make it stronger.

Porsche's can handle it easy.

Was it SRM, or your bad shifting that destroyed your motor? In case it's not damaged, that is.

Would you have preferred me posting a new thread? Truth be told; I'll take a necrobump versus a new thread every day. That way it mitigates the duration of time it takes for someone to find what they're looking for via the search function when there is only one or two threads covering the topic.

No disrespect intended I was just particularly amused at the length between posts and took the opportunity to post a meme (one which I thought was pretty benign and not belittling). It seemed like you were responding to a 2.5 year old post.

You are absolutely right, especially with topics such as this. Thank you very much for using the search function and having the perspective that you do. That helps make this forum the best one on the interwebs

I wonder how they are going to make guys look tough driving when there are so few real manuals available. Hard to look tough flicking floppy paddle shifters. Cracks me up when commercials try to make a car look fast when the guys hand is on the shifter, but it's an automatic. I fear when I'm ready for a new car I won't be able to find a stick anymore. I think most of the new Porsche and Ferrari are only available with 2 pedals and floppy paddles. Faster, but takes some of the driving involvement away. I like using both feet. And not for left foot braking, which being an old coot, I can't get my head around.

Threads like this are comical. We have guys who probably have never lifted their hoods commenting in here. Some of the posts really show that.

There is one big difference that Mt Tam I Am sort of mentioned. There is a huge difference between over revving under load and over revving under no load. The loadings on the engine are completely different. I would not be worried about over revving for a quick duration, if the engine didn't drop a valve or break the oil pump your fine.

Longer than a just a quick blip of the rpms and I would be worried about the engine moving towards dangerous harmonics than anything else. Its those harmonics that would absolutely kill an engine (again the harmonics under load are going to be different than a quick overrev). I would consider the biggest limitation (aside from harmonics) to setting a redline for a particular engine is in the heads, more specifically the valves.

Think of it this way, unless an engine is blueprinted and truely balanced (and we all know that nothing is perfect) its like taking your very very slightly out of balance tire and accelerating with it. You can easily feel when the tire starts to vibrate the whole car, then as you go faster you may notice it go away, but there becomes a point when its going to get much worse as you start to move towards its natural frequency. The same thing will happen (and does happen) in your engine.


Anyways, sorry for the bit of a rant. I promise you your engine will be perfectly fine. If you were going to do damage you would have known right then and there when you dropped a valve.
