Redline
 

Quick question to those in the know:

Is the redline of the 996TT 6600 RPM in _all_ forward gears?

Thanks.

The redline in reverse is actually 9,000 rpms.

Just kidding!!!
How are you Skaria?

Thanks for the info Ken. That info really helps! I'm good... keeping busy tricking out my wife's SLK. For the price of a GIAC chip, I can do every single mod in the book available for the SLK.

Back to my original question before I was rudely interrupted by Ken. ;-) Does anyone know the redline RPMs in the forward gears?

Thanks.

Re: Redline
 

On page 69 of you owner's manual, it says:

"The beginning of the red marks at the right end of the scale indicates the maximum permissible engine rpm."

Since the engine spins using all forward 6 speeds and reverse, this statement applies to all 7 gears.

Wow! Those manuals are sure handy, dandy things to read, aren't they? Anyone seen Jim Bob lately? I sure miss him.

What about reverse?

Well, that is the 7th gear I mentioned above.

I think reverse is actually first gear, only in reverse. ;)

I actually heard that reverse on most cars is smaller than first except on Porsche!! No wonder most people with upgraded clutches stall in reverse...

Stock redline is 6750 RPM, for TT model. I had EVO raise mine to 6950RPM with no issues!

I wonder if he's asking because the rev limiter in the '04 GT3 is 8200 rpm in 1st thru 4th but 8000 rpm in 5th & 6th?

No, the only reason why I was asking was that I got cut off a couple of times at a little past 6000 in first gear recently while the other gears were at the red mark on the tach. I never really look at the tach when I drive in the street and I only looked recently because I hit the rev limiter.

Thanks.

The reason you reach cut off (rev limiter) at ~6000 RPM in 1st gear (only a problem near or at WOT) is because the Tach is analog and the limiter is a direct digital read on the crank. In 1st geat at WOT the engine spins up so fast (due to the 13:1 overall ratio) that the analog Tach can't keep up with actual engine RPM. So when you reach ~6000 RPM on the Tach accelerating in 1st gear (~WOT), the engine is in fact already at red line. In the other gears, the acceleration rate of the engine is "slow" enough for the analog Tach reading to accurately relay actual engine RPM.

When accelerating at WOT in 1st gear, I initiate the 1-2 shift at 5800-6000 RPM...maximizes the power and provides much smoother shifts, since trying to shift smoothly once the limiter engages is just about imposible.
