Was told by seller that 24,000 ignitions against the limiter in Range 1 was a clean DME for a 996 GT2 with 5 k miles. Also, had almost 300 ignitions in Range 2.

Im more familiar with 997 GT2’s, but the above didn’t sound like a clean DME to me for a low mileage car.

Thoughts.

FYI - last overrev was about 20 hours ago.

 

At 6k rpm there are 300 ignitions per second. So that is 80 seconds on the rev limiter and 1 second in range 2, 20 hours ago. At an average speed of 50mph that was 1,000 miles ago. I would be more concerned that it only has 5k miles in 15+ years. These cars love to be driven and punish those that let them sit.

 

So 24,000 over revs is not a lot in 5k miles?

 

does/has it had a dme tune/flash on it?

 

Allegedly all stock.

I own a few 997 Turbos and none of the DME’s have anywhere close to 24,000 overrev ignitions, especially in 5k miles. Just thought it was a bit of a stretch for seller to claim that 24,000 overrevs is a clean DME.

 

very high if truly stock, poor driving
if tuned and used fully its completely plausible... betting its been tuned..not sure I'd call it a 'clean' DME readout but probably zero concern either, 996 counter's are lame
from today

 

This doesn't add up. How can you have 5k miles and 2700 hrs of run time? That would be an average of < 2 mph avg speed.

 

Thanks.

Agree. Didn’t think it was going to spit out the rods on the next drive, but did think it was stretch for the selling dealer’s rep to characterize 24,000 overrevs in 5k miles as clean a clean DME.

Going to pass on this GT2 anyway as the prior owner installed a rollcage, but it allegedly was not tracked ... with 24,000 over revs in 5k miles.

 

The 2700 hour DME report is not from the 5k mile car. Someone else posted that report.

The 5k mile car has 180 hours on it.

 

Different cars dude
It's probably been enjoyed happen to be the car that was/is at CNC?

 

I believe it’s the same car...

I was onboard with potentially making the purchase until dealer rep characterized 24,000 overrevs as a
“very clean” DME report. Then I began to wonder about other characterizations as I am an out of state buyer.

 

As mentioned the 996 DME reports are lame and type one overevs while not a “clean” DME and with only 1 second of type 2s plus it’s been running for a 1,000 miles since, I woul do a compression and leak down test and if all good I wouldn’t sweat it. Also, as mentioned, if the dme ever had a flash/tune that would result in overevs that register but don’t necessarily hurt the motor.

 

Agree, but they have some value, such as 24,0000 overrevs to warrant a closer look by doing a leak down.

I thought I missed something when in what universe 24,000 overrevs was not just a “clean” DME accordinging to the dealer, but a “very clean” DME on a 5k mile car. I suspect that’s dealer babble when they want to sell a car. I venture to guess if you wanted to trade your GT2 to the same dealer they would hammer you on value with a DME report like on this car claiming the pin was out of the Mezger hand grenade and it was only a matter of time before you needed a dust pan to sweep up your engine parts.

If dealer had been straight up and said the DME doesn’t look great; however, I’m happy to do a leak down and compression test to show the motor is unaffected, it would have gone a long way toward selling the car.

 

The big risk with the over revs is the timing chain blowing apart. If it's lasted quite a while after the over revs its likely fine. The chains are pretty tough, you'd really have to bang one to break it.

 

Is the car tuned? Increased rev limit can have direct impact on these value with no abuse.
