On accident I have reved over 7K and hit 8 at least twice now. I have let off the gas right away and pushed the clutch in immediatly but is that going to do a lot of damage? I never mean to do it. Once it was out of my control and the other time I was screwing around in the snow and the revs just sky rocketed on me. I also have a ZE.

Thanks

i doubt it,i do it all the time and the motor still runs the same.just keep up with the maintainence of it.

yes it is bad, you can bend valves easy, and most likely your lifters get lots of damage and you can ever hear them pinging.

the ticking lifters are normal even if you dont drive hard and i doubt you will bend valves...there pretty strong motors obviously.

is there other ways for valves to bend besides hitting the piston? non interference engine is what we have

well i know i took mine well past 8 grand. all it did was blew the timeing belt. thank goodness its a noninterface engine. i think around 7 grand is where the engine makes the best power. just be careful not to go too high with it.

ok i take back what i said...i did some thinking and im a jackass,that being because when i had my old mustang i went through 3 engines all because of over revving. sure doing it on the ze or k8 whatever doesnt seem to do much but eventually it will break something in the engine...besides that shifting past 7k doesnt make the car any faster IMO.i actually gotta quit doing it myself cause the engine feels weak already,as i stated in the past,ever since after the first week it just doesnt pull like it used too.anyways Dont rev past 7k too often.

If you rev the motor with it in neutral..thats where you do damage. If you rev it when there is a load on the motor (like when its in gear) then it isn't really a bad thing to rev it high, as long as you aren't revving it for prolonged periods or revving it numerous times a day like that.

In my view, there's no point in intentionally exceeding 6,500 rpm (max power point) with a KLZE. Change up to the next gear for higher torque = more acceleration.

Its called a redline for a reason

Why the hell are you guys reving so high anyway? I RARLEY pass 4,500rpm...

ever drive a ZE in the snow trying to have fun? Its easy for the revs to just take off on you at any second. Like a I said it was a accsident. When I race I **** at 6700-7000 though and I race about 2-4 times per week. What are you doing with your ZE?

Accidental. The engine's so quiet on the stock K8, that sometimes I have completely forgotten to shift.

You will actually destroy some engines if you always keep the rev's low. My friend bought a 90 RX7 GXL and it's motor died b/c the previous owner never revved it past 3500. Those motors NEED to be revved if you want them to last.

This is the same for most engines, even the K8 or KL motors. You want to rev them high every now and then to prevent carbon build up from building up too much internally.
