Could this be one of the reasons for keeping the engine tray installed (to avoid grass fires that is)?

A better option is to remove your cats with the engine cover removed. <img border="0" alt="[cheers]" title="" src="graemlins/beerchug.gif" />

poor kid, it appears it was a son driving his fathers car and the kid was just in tears. I'd feel so bad <img border="0" title="" alt="[Frown]" src="frown.gif" />

You can't remove the cats in the 993tt - you'll get the check engine light and possibly go into limp mode. It is because of the 4 o2 sensors - from what I've heard. The best you can do is put racing cats on.

viperbob

ahh, no that is not completely true. I have the FVD cat bypass. No limp home mode ever. When I first put them on, I got a CEL after driving 100+ miles. After a reset it came on again after another 100+ miles. After the second reset it has not come back on with another 1000+ miles of driving. The ECU in the 993TT has a learning function that now assumes this condition is OK since it has been reset a couple of times and the condition still exists.

Same here Bob. Got my first CEL after a 100+ miles after the cats were taken out. Scan tool software showed 'catalyst system efficiency below threshold'. Have reset it and hasn't surfaced since but still beneath the 100 mile threshold so I'm waiting.

Now for the True Facts.
That is my car. The accident occurred Sunday afternoon at Texas World Speedway at College Station, Texas. My son and I were sharing the car, which we've done with this and previous Porsche. I was running in Red and he was in Yellow, both solo. He lost it in turn #4, left the track backwards and slid about 150 ft. through very rough grass/rock and small brush/tree area, kicking up pieces of dumped asphalt and coming to rest on top of a large mound of concrete that was grown over with large clumps of 2ft tall dry grass. The car has (had!) Fabspeed muffler bypass pipes coming off of cats. The cats set the grass on fire and then the car caught fire. He tried to restart and move the car before the fire started, but #1 it wouldn't start (I found pieces of wastgates along the tire trail) and #2 if he could have got it started, the car was lodged on the concrete mound. He was so far off the track that the corner worker didn't see him go off and the fire trucks weren't called until he ran about 200 yards back to the corner worker screaming fire! It then took several minutes for the fire truck to get to him. It was probably the worst area to go off, except at tire walls.
As I told my Son, who yes, was very upset over wrecking my cherished turbo, (he knows how many years it has taken me to work for it) "your not hurt, you didn't t-bone a Ferrari, I didn't buy it to set in the garage and no, I'm not going to kill you". Resale value will suffer, but since I planned on keeping the car till I'm too old to shift, it will rise up from the ashes, and I shall name her PHOENIX !!! Their pulling the engine this week, IT REALLY ISN'T AS BAD AS IT LOOKS, REALLY. Oh well, wishful thinking.
Power oversteer can be a cruel lover...be careful out there!

PS on that's my car.
The engine tray was removed, but it doesn't cover all of the exhaust sys. anyway. Fire would have started, but maybe less damage to underside of engine. The ambient temp on Sat. at the track was about 101deg. so I would still run with undertray removed. No fire ext. on board, but you can bet whatever I take to track next time will have one.

Paul,

I respect your priorities... family first, the toys are way down the list. Your Porsche will recover, and someday... perhaps 20 years from now, you and your son, who will have developed an even stronger bond, will have a good laugh together. A more pragmatic question... will your insurance cover any of this damage? Anyway, best of luck to a guy that seems to have his head screwed on right.

John H. in DC Area

Thanks for the informative post, Paul. And I agree with Steve, you've got your priorities straight and have a great attitude. Your son's fortunate to have you as his father, as is evident from your sharing your ride with him and your attitude about the car. Good luck with the rebuild.

PaulP

Thanks for the words of support. The son that had the accident is 31yr. old and we have always been close. I am very proud of him. I did take time to notice during all the commotion as the wrecker dropped the car off at the track garages, that everyone (big crowd as you would guess), was supportive and had pain on their faces as if it was their car. Motorhead personalities may vary, but we all share a common bond when it comes to automobiles and driving. If my Porsche could talk, I believe it would say, "Do not weep for me, my friends, for I have lived a good life!".
We are working on the insurance, but won't have official results for a few days.
I'll let you know what the outcome is.

viperbob

Paul, good luck and I admire your attitude. I'm glad your son was unhurt in the incident.

Paul,

As a father of two (a bit younger than yours at 3 and 5 yo <img border="0" title="" alt="[Wink]" src="wink.gif" /> ), I loved reading your post. I also regularly track my 993TT, because that's where it's happiest. I hope I can share it with my son and daughter some day at the track.

I'm glad nobody was hurt, and hope that the rebuild goes well.

Oh No... <img border="0" title="" alt="[Eek!]" src="eek.gif" /> Paul I remember seeing your car at TWS in March at another Driver's edge event and it sure looked incredibly beautifull. I was under the impression that you were selling the car at that time?
Anyway that T4 is terrible and slippery, I had a couple of 360's there as well, fortunately by luck I ended up on the road without damage, but a few cars have had worse luck than you on that turn.
I'm really glad both of you are safe and I hope your Phoenix will raise from its ashes looking as beautifull as she was before! <img border="0" alt="[byebye]" title="" src="graemlins/wave.gif" />
