Say you're going up the gears and hit the rev-limiter, is this a big deal? I'm guessing car and engine are just fine, but does this generate any type 2 over-rev readings.

I was under the impression that hitting the rev limiter generated type 1 over-revs, but searching through the forum I wasn't positive I had this right.

If you have a flash that raises your redline by 500, is the ECU smart enough to adjust the limit for type 1 and 2s by an additional 500? Or does it consider every intrusion past the old redline as a type 2?

Finally, just curious, does anyone on here have a 6 speed with zero Type 2s?

 

No. Yes, yes.

Yes => I have a zillion type 2's just from going up the gears (and staying over redline for VMax runs)

Dunno, dunno.

Probably not

Same as Jimmer

 

Mine definitely has a couple...but runs very strong...the limiter is there for a reason and generally does a good job (on the upshift front anyway). Downshifts are were you open up your wallet and the bills flow out like the Niagara Falls...

 

Everyone on this post correct so far.

 

I was told that after a while it does affect your clutch. It weakens it's clamping ability because when the rev limiter kicks in, it disengages the clutch to prevent engine damage; choosing to slightly weaken your clutch instead. A few months ago there was a brand new green Gt3RS in the shop (Atspeed Motorsports). It was there because the driver mis-shifted from 4th to 1st by mistake and the shop mechanic said it reved over 10k when the transmission just blew saving the engine. Unbelievably, Porsche made the repair under warranty afer a few months of negotiation.

 

If you purchase the car from somebody who drove it at low rpm all the time and never exceeded the revs remember there is a ridge at the top dead center. The connecting rod and piston move to the same point all the time. If you go to higher rpm suddenly because you are driving this new car more agressively be careful. Because the connecting rod and piston will have tendency to extend (I am talking about one thousand of inches) and hit that ridge. And you can damaged the upper piston rings. Taht was the case with a Carrera I had in the 80's....
