A C6 Z06 went kaboom at Texas World Speedway today. This Makes 12 Vettes that have blown up there in the past 90 days. This seems statistically improbable. Are any of you guys owners of the cars that have gone boom at the track events there? I sure am curious as to what the different failures have been....

I skipped that event because running CW the G's pulled in 3 to 2 to 1 is too much (IMHO) without a road racing pan or Accusump. I made a post about this a week ago. Now maybe this one was not oil starvation related but I'm not taking a chance. I'll run the next event when we run CCW. The G's are way less running CCW.

Not likley, C6Z's have a dry sump system. Accusumps are not necessary nor wanted on a dry sump engine, that is what the 8 quart tank does. I have 13K miles on mine and many many track days on mine, no issues.

RedHotBolt

Your right. I forgotabout the fry sump. But since I don't have a dry sump in the C6 I still worry about TWS going CW.

The oiling problems with LS1's are in left hand sweepers. The big, fast sweeping turn when going CW is a right hander. I have run my LS1 stock Firebird clockwise several times with no problems. I add 1 extra qt of oil, and go at it.

Besides, CW is WAY more fun that CCW. Turn 7 is AWESOME doing down hill and being able to see the exit of the turn.

Jerry, I missed that other thread. Do the C6's (including Z51) have an oil starvation issue with sustained G loads?

P.S. I like CCW at TWS more than CW.

I'm at TWS this weekend. I think it was three corvettes that went dead. A red one (with 427), a yellow C6, and a black C6 Z06. The fact that they are all different models and years AND engines makes me think that it's just bad luck. There are quite a few running fine. I'm running a half quart high in my C5 Z, and having no pressure issues in the big right sweeper.

kraemer007

WOW, that makes 14 now. I hadnt heard about the other 2 cars.

The red one is mine. Timing chain jumped, will have it ripped apart come monday to find out the full damage. I know who owns the yellow C6 but I wasnt aware of a C6Z breaking?????

Severl of the C5 (LS1&6 ) and C6 ( LS2) have lost the #7 cylinder. Most likely do to oil starvation.

Some of the EARLY C6s and C6z crapped out do to harmonic balancer problems which was fixed and early LS7s dropping valves, which was also fixed before release to the public.

We have many choices to do many differnt tracks, rovals with high G corners my sound like fun, but oil starvation is strong possibilty when there is no sump systmes.

Also on rovals rember NASCAR cars have tire inner liners in case of a flat. Our tires dont. Out side walls can come up very fast with a flat tire and no inner liner.

Well, I'll be out there the 16th....hopefully mine will hold together....putting the LS7 clutch and flushing the clutch fluid....maybe I can actually shift into gear after the front straight this time....

RedHotBolt

I don't know about C6's starving for oil at TWS but my sons Mach One did at the last event where we ran CW. I just worry about it because you pull so many more g's than when running CCW.

I'll be there too, I'll look for you adn say hi

RyanZ06

LOL -

This thread is FULL of mis-information.

There were indeed 3 vettes that went "boom" this weekend..

One being the vette i was driving.. 99FRC.. NOT a 427 .. The timing chain (roll master double roller) let go on it.

The yellow C6 (NOT A Z06) caught fire due to an oil cooler line problem, it was quickly fixed, and no real damage occured.

The other was a C6 Z06.. I dont know the specifics.

yakisoba

Ah, my bad. I'm sorry for the bad info. I was pretty sure Taz's was a Z, but it now I think on it, perhaps not. Too bad about the timing chain. I'm about to replace mine, in fact. The C6 Z06 was ForHamilton's (forum name). I know that's right because I helped push it onto the trailer

Mojave

You know, Chris, to be on the safe side, you should just let me drive the Z06

hey i met a few of ya'll today at the track I didnt get to talk to many of ya'll but i met someone with an Orange vette pulling into a trailer I was in the white c6 that just barely was broken into.. I'm glad to hear that its not a common problem in c6's to blow up

btw how many people live in the south side of houston cuz i'm interested in getting an exhaust and would like to hear how they sound

Hi Victor, great seeing you out there today! You have a beautiful car, a good friend of mine in Austin has a white with black interior. Remind me of his!

Thanks for listening. I haven't had any problems with my car all year. I contribute this to putting in a mild cam, headers and intake-manifold. Overall I added 100hp to the car and brings a nice sound. I also run redline straight 40w oil without any issues. I've left it in for two months total. I watch my oil pressure, but haven't seen any problems with mine since I've been driving out there - that was the case way back in Jan of this year when I came out with Lou Gigliotti's advanced racing school with viper days racing!

Look forward to seeing you at the drivers edge's other events at places Like Cresson Motorsport's ranch, Texas Motorspeedway, Eagles Canyon and the Drivers Edge home track Racer's Ranch (slated to open in Q3CY06).

Again, good to meet you and feel free to post here for advice on Mod's - ForHamilton will suggest brakes, tires, and suspension before we suggest adding more power!! Pretty much in that order!

Cheers

JK

do you only go to DE events or any other events? just curious and it was great meeting you too btw!
