Possible overrev on the track; does ECU store max lifetime RPM reached?
Hi all!
Had a blast doing my first HPDE in my '17 BRZ yesterday. There was one big braking zone where I figured we were suppose to go from 4th to 3rd to 2nd. One time as I was attempting this sequence, I got into 2nd too "early" in the braking zone, meaning that the wheel speed was still too high. When I glanced down quickly, I recall seeing 64mph, which means roughly 8300rpm in the engine, assuming that the rear wheels spun at the same speed as the front. That freaked me out good and I learned to wait a little bit to downshift into 2nd in that corner Questions:
Thanks all! |

If you're not hearing any abnormal sounds from the valve train I would call it a day and not worry too much about it. There isn't anything you can do at this point.

Over rev failure is one of those things where it breaks something, or it doesn't. You'd be hearing some clattering if you broke a spring your car gave you a second chance. I agree with the others, find a way to datalog and review it after events! You'll definitely feel more connected with the car

Nah. I'm one of, like, 7 twin owners who actually likes the stock taillights, lol.

I am as well! If (or when) I get a new one I will probably be offering to swap with an preface lift set.

I've never reached 8.3K rpm, but I've revved to 8K several times with no issues.. over the course of 60K+ miles at least. |
