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

Jordo! · 02-16-2011, 12:57 PM

Oh, if only just over 8K he's probably fine.

Bunny pic = "this makes no sense"

I did this once by accident when I first got the car. Now it's at 8K and it's running fine. I was going 60ish and went from 5-2, then clutched in.

Jeffblue · 02-16-2011, 01:27 PM

my short shifter saved me from doing exactly that. was going pretty quick, went to shift into 4th but gated it into 2nd, but i was able to feel that it wasn't in the right gear before letting out the clutch so no harm was done. B&M shifter ftw.

Like importconvert said, changing your grip on your 3-4 shift can help avoid shifting into the wrong gear. if you just do the kung fu death grip for all shifts you are more likely to pull towards your body.

You should be fine. I've hit 9500 rpm in mine once. She screamed like crazy, but that's about it

in this case, i never mis-shifted per say, but since the computer automatically over-revved for me, i realized my mistake before it was too late.

Yes! I did the same thing. The shift gates are fairly narrow as we know, so it's pretty easy to go into 2nd instead of 4th if you're not careful. But when I got the shifter over to 2nd the SRM kicked in and revved up the engine about to the red line. I caught my mistake before letting out the clutch and no harm was done!

Normally I'd be mad about the thread necro, but I love seeing whose car I shouldnt buy.

kenchan · 08-12-2011, 11:09 AM

i guess the benefit of having SRM is that it wakes you up when you enter the wrong gate as the engine rev's up electronically, but you get a moment to fix the situation before you clutch-out so you dont have mechanical over-rev.

mechanical over-rev = not nice to engine.
electronic over-rev = bouncing off rev limiter = no issue.

tjlazer · 08-12-2011, 11:26 AM

I did this today! I went from 5th to 2nd at around 50 MPH. BUT I did not go into gear, SRM saved the day!

Jeffblue · 08-12-2011, 11:43 AM

If you can't blip the throttle or put the shifter in the right gear... just buy an automatic.

How many aspects of shifting can the car perform for you while still being a manual transmission. I think we need a feature in which the shifter actually moves between gears for us and then we can just kind of hold on and pretend we are doing it kind of like those pianos that play themselves.

wakes you up, doesn't it?

ive done it too a few times. the gates are slightly different from my G which i drive daily so it's a tad tricky for me when i get in my Z on the weekends.

mantella87 · 08-12-2011, 12:43 PM

That's why a 3rd to 2nd misshift is called the "money shift". I think your engine is fine. Just be more deliberate when shifting from now on.

LOL... good point. So much for airing laundry....

Funny rabbit pic.

I've done in a Porsche 911 several times on track from 3rd to 4th & hit 2nd instead wearing gloves. Kind of makes you feel like a fool. Most Zs I would think are built to occasionally go 2k over redline no problem. Rough on but not devistating to a high performance engine/trans. What is redline speed in 2nd?

No. 2k over redline runs the risk of engine parts in your legs.
