911SLOW posted a 300,000 Mile GT3.

What year is that? more info? How many engines??
Are there other known high mileage GT3's??

Curious to find out more.
High mileage I know is I think Snowboarder 54 with I think 50K + miles..
Seen some for sale with 60K miles, not much higher..

 

Wow 300k...

 

That is a lot of miles. Where was this one posted as I must have missed it?

 

that picture wasn't a GT3. it was a turbo.

 

You're right, no RPM's.

 

There is a US guy on 996 GT3 forum at 100K

 

does this mean that the Loctite joints last that long?

 

Yup
JR944's GT3





And there was one for sale in the UK with 180K still on PCCB.

BTW T2's turbo has 300K on the original PCCB discs

 

There was a 996gt3 sold recently at 911virgin (england) with 180,000miles same engine, gearbox etc etc it sold in 1week!!

 

Bigger clue was the word "BAR" on the bottom of the LED display...

 

^You are new here?

It's like he never saw it.
Peter can't see the word bar without automatically assuming it's a quality beer calling and run for the fridge.

 

Bwhahahahahaaaaaa!!!!!!!!!!!!!! Touche'

 

Right, I thought it was the text only display of a 996 with satnav.

heading out for lunch with quatro punto cero now

 

Two main factors on engine wear: Heat and RPM, and the GT3 has plenty of both.

If you properly warm up your GT3, drive under 4,000 rpm, and change the oil every 2,500 miles, it will surely last a long time, any babied engine lasts a long time.

A GT3 engine in track conditions (read GT3 Cup car section) is good for 80 hours, some people stretch it to 100 hours and a little more. At 85 mph average, 80 track hours is 6,800 miles.

6,800 miles is a number far away from 300,000 miles.

My 2007 GT3 RS with somewhere around 3,000 track miles, and 20,000 miles on the odometer had an engine rebuilt due to a multitude of oil leaks. The car got a new crankcase, the engine builder (good friend from L.A.) showed me the opened engine, indicating the wear on the crankshaft and some scratches on the cylinder walls, it would have required a rebuild at the 35,000 miles range with my use. It tells me that in addition to the track miles, it was driven hard on some of the non-track 17,000 miles.

So, keep written records of you track days, miles driven, minutes at the track. Perform a leakdown test at 40 track hours. At 80 track hours, I would in addition to the leakdown test, inspect the cylinders with a camera, the crankshaft is almost impossible to get inspected, unless the engine is opened.

If you distribute the cost of a rebuild, over the # of years that it takes to accumulate 100 hours when doing DE Cup, the rebuild ends up cheaper than tires.

 

I keep these records on Giesha
