Rev match scare

Nithmo · 11-20-2016, 05:12 PM

If anything, the synchro rev acts as a warning bell, if you're not down shifting too fast. The worst that will happen is the engine will hit the rpm redline and bounce off it, but not surpass it. That in itself isn't anything to worry about. Only when you let go the clutch, will it go past. And then you spend mooooon-neeeeeh!!!

Sorry in advance OP, but I gotta point this out. A few months ago, in another thread, you posted:

"you can shift at 6k all day long and it will never hurt the engine. that is not even touching red line."

Damaging a Z..

And now you worry about one single no-load rev. I am confused

I drive my Z 60 miles a day, as a driver in heavy interstate traffic.

It gets to 7200-7500 at least twice a day. I generally drive the AT in M, and can shift it just before redline now by feel.

I did jump on it the other day thinking it was in M, but it was in D. I upshifted it manually by instinct, and it went to Neutral since the shifter was in the wrong slot. It went to 7700 immediately, since my foot was flat on the floor! This is not good - since there is no load on the crank. Hasn't seemed to have bothered it at all.

Keep good clean oil in it, at the correct fill level and temperature, and this engine will tolerate a lot of abuse.

revmatch will not hurt the engine, this is not an issue

I was around 7k RPM on 4th gear and was about to shoot it to 5th but I accidently shot it to 3rd. Engine screamed and I felt terrible. But nothing happened afterward. VQs are pretty solid engine.

I neutral rev all the time. I hit redline in first and 2nd more frequently than not. I sit at 4k rpm when I'm near a prius.

I slow down and downshift entering a tunnel and wot redline through it.

Aslong as your temps are good it's fine.
Hmm

It's quite safe to blip the throttle to that point.
