A stock engine will fail when your rod bearing fail.. Either thru detonation or lack of lubrication to cool the journals. There was bearing transfer on the journals.

That's my point, a stock motor in good shape will not brake just like that without something else having caused a failure, an issue with the mapping, overrevs or oil starvation of some sort. Otherwise should see years of DE/track usage.

I agree Jean, I was talking with some cup mechanics at Spa and I mentioned about rebuild etc, they said if stock motor (minor mods) and has more than regular oil changes etc there should be no issues, car would run forever was the exact words. It's got me thinking, I might cap my boost down a little, but I usually do a mix of 109/99 (50/50) for track just to help detonation and run decent Motul racing oil, which is changed often. Off to Nurburgring on Thursday, watch this motor will proabably blow, ****!

Stock engine means stock.. No boost change, no exhaust, no headers, no wastegate mods no shift kit, no ECU mod.. Most guys that track there cars mod there car. ECU flash, wastegate mod, exhaust, short shifters.. It can take anyone of these factors to accelerate the bearing wear. This engine has had 1200 degree of heat to transfer the bearings to the crankshaft. A missed shift, or detonation would cause it.. Changing the REV limit to above 7K or constantly kissing the REV limiter would cause these conditions.
Again, a stock engine should not fail on the track or on the street. However there are stock engines that do fail. Walk into your Porsche dealer and see Vario cam failures and cylinder head failure due to corrosion and poor castings. These cars aren't tracked. If the engine has been enhanced coupled with a missed shift the rod bearings will take the hit. The rod journal/bearing got so hot that the drag on the rotation of the crank caused it to snap in half.

Even though we have never crossed paths, I have followed your posts and your progression in the DE world. I started down the slippery slope back in 2003, modified my TT, and enjoyed many,many weekends on track. I was getting very proficient on track, moving up to the high run groups. Last year, I began doubting myself and my commitment to the track. I too was championing the idea of a dual purpose car. Always saying that the TT was just about the best dual purpose car out there! But with the changes in insurance coverage and my concern with the car's durability, I stopped tracking. Just the money I paid for a clutch ($4600), could have paid for a fully prepped track 944. I saw one for $5000.
I just could not justify putting an $80K investment at risk every weekend any more. I was just not financially able to make that commitment. I made the decision to walk away. I am still planning to get back on track with a "track car", one that I can walk away from on any given DE weekend.
Best of luck to you and whatever you decide to do.

Sorry to hear about this...could I ask a few questions? sorry for being a newb..
How many total miles were on the car? Would the warranty cover a motor from a car that has been tracked..if not modified? thanks hope it works out for you.

I run the TT at the open passing time trial level so I guess it is race conditions but I am addicted to that car. I have two 944's that I do wheel to wheel racing with and can afford to walk away from them if I crash.
Still hope to see you around RA sometime!!

Tom,
Obviously there is no choice but to fix it. But the question is to fix it as a street car, or as a dual purpose street and track car. I have never been convinced the latter is a good idea, especially on cars as expensive as a tt.
Would it make more sense to just move on to a dedicated high-power track car, a new GT3, or (heaven forbid) a ZO6?
I think the big problem will be a second melted motor in the tt. Nobody gives you a waranty on track motors, and as we all know, **** happens. To me, that **** is just more tolerable on a Chevy small block, as it is also cheaper.
As you know, my X50 sees only occasional track use (primarily for instruction or demonstration) when I bring doctor guests. Otherwise, I use dedicated track cars. It can be somewhat jealousy-invoking, when my buddies just drive off while I am still loading and trailering. The upside is, I always have a car to drive home.
For a prepped new motor, you will probably be looking at 50 grand, before the whole thing is over. If I am way off, I would appreciate being educated. I might put a used tt motor in, and buy another track car. I presume you are already trailering your 944's, so you also probably have the whole rig.
On the other hand, I will be very interested in your choice.
There is nothing logical about our hobby, and it remains the best known means of turning money into noise. Keep us posted. My bet is you upgrade a tt motor. Personally, if staying with Porsche, I think I would be looking at getting in line for a new GT2, and leaving that bone stock. I have a desposit on a new CLK Black, but the dealer may be getting cold feet-so I am unsure of my own car destiny. AS

car had 20k on it near 10 of which where at the track. I got the car with 9k
and no a warranty will not cover your blown engine at a track event.
