Default All you enthusiastic drivers : Do NOT OVER-REVV

Just came across these posts on the S2000 board, and was surprised that some S2000's have had to go in for a complete engine rebuild. Some of the cars were almost brand new, while some were fairly run...but none even close to what you would term as an end-of-its-life kinda engine.

After some further investigation, I also found lots of Corolla, Nissan, Mercedes and various other car owners who ended up with their engines seized after a bout of really aggressive driving. It doesnt matter if you didnt hit and bump off the revv-limiter..Even if you stayed at the red-line consistently...chances are your engine is already damaged.

Also do take a lot of care while downshifting or mis-shifting, especially when you are in a high rpm range. While you may intend to shift from 3rd to 4th and mistakenly end up in 2nd - You can say bye bye to your engine.

I am really surprised as I would have thought that the revv-limiter would be modestly set so even if you do bump of the limiter (when you engine feels like its jerking - fuel supply cut off), it wouldnt really damage your engine.

You have been warned. Respect your machinery and it will, in turn, respect you back.

This is a sample over-revved S2000 engine. Owner got more than his dose of Vtec'ing

I am certain Dippy remembers going down to second, instead of fourth....And this was after redlining!

If over revving is taking the car to 4000 to 5000rpm before upshifting then I do it nearly everyday....Please dont tell me that this will damage the engine? Coz I love driving this way. Whats the point in having a fast car if you cant rev it.

At the track recently, I was on the red band all the time and I downshifted once or twice at high revs from 3rd to 2nd, hope I didnt do any damage to the engine :O!

No offence meant, but just what the heck were you doing with Santro at 6700 rpm?

I think we can ignore the 6700 rom, can't we? He shouldn't be doing anything with a Santro on the road in the first place at the age of 17.
