Default high revs.

Sometimes when I floor the accelerator in manual, I forget to shift up gears and you hear the engine scream ....how bad is this. It's happened plenty of times.

Bouncing off the rev limiter often is not a good thing. You will end up bending valves and damaging the cams.

If you're forgetting to shift, it would probably be best if you left it in D.

I have done it plenty of times in a 03' Z06 . And it's happened a few times in the F . I hope they have enough safety built into the stock ECM to eliminate engine damage as well as a pushrod V-8 Chevy !

Seriously, you could bounce it off the limiter all day and it won't complain nor will it fail any sooner. It's not advisable, but that's why the electronic limiters are there - to protect the engine from driver mistakes.

I was thinking the same, theres a reason why the rev limiter is there, to prevent driver's mistake. Its really hard to over-rev an automatic car, Different case for Manual cars...

I would be more worried if the car is not fully warmed up. Otherwise, drive it like you stole it

Jesus, you probably shouldn't drive the car in manual if that is happening. Manual cars might not be for you.

Confirmed, it's not a DAD thing, my DAD drives pretty well.

Very True.... !!!


I found another "mistake" limiter when I was R&Ding the 350 way back when and its also present on the IS-F ...

When you select "P" Park, after switiching out of another gear selection, the rev limiter will not allow you to pass a certain RPM...
Even if you mash the gas pedal to wide open throttle..

You have to wait a couple of seconds, before you can rev hard...
