How Many Over Revs Are Too Many?

[klueless7571]

I'm considering a 2004 GT3 with 30,000 miles on the clock. The DME reading follows. The range 1 revs says 65535 (2^16) and that looks like the limit of the computer's memory. I know these are the type 1 over revs and should be safe, but is that still too high? Does that indicate this car's been tracked? Anything else you guys notice about these readings?

You have no Range 2 over revs - you can not ask for better.

Range 1 over revs were caught by the rev limiter and don't mean much since the rev limiter protected the engine. Range 2 are the bad over revs.

Hi there, 

I am considering a car 

Range 1 3000 ignitions

Range 2 600 ignitions

 

Should I be concerned ?

Sorry, I am such a noob! 

2004 996.2 GT3, now I got the details (I guess I overestimated my memory :-D); 

Range 1 approximately. 37000 ignitions
Range 2 approximately 4200 ignitions @ 703 hours
Car has now approx. 780 hours

I checked with my PIWIS the cam. dev. and both are in norm at bank 1 - 0 degrees bank 2 - 3 degrees.

Range 1: 7300-7500 RPM

Range 2: 7500-7700 RPM

 

Range 1 is likely hitting the rev limiter while accelerating. Likely safe.

I would not worry about any of those Range 2 over revs either - likely one missed downshift could do that.

Hi there! 
 

according to https://911virgin.com/engine-revs/ 

and other sources on a 996 GT3 

 

- range 1 is 8200-8800

- range 2 is 8800+ 

 

so I hope I am wrong because that would be excellent. 
 

thanks !

Yes, you are correct I did not see the GT3 part - my bad.
