it does happen. what tires/engine/power?

 

Am I to assume this happened after dumping the dual-plate clutch at high rpm with slicks? I've seen axles snap, but never those gears rip themselves apart, esp in that inconsistent pattern.

 

the same thing happened to me when we used an ls final drive with a b16 countershaft.

 

here ya go

no dual plate clutch, it was an act xtreme pressure plate and street strip disk and it didnt blow until second gear, but it was the hardest my car has ever launched

samething lol my car is a street car to, drove it there and have never had any trans problems what so ever, it was a stock gsr trans and it has never been apart

 

The pin that hold the spider gears shears and the dowel comes out, been through 3 of them. The last one I took apart and welded the spider gear dowel into the carrier. We'll see if this one goes

Ding ding ding!

You can do it with a single diaphragm disk, too. I have video of an ITR trans taking a big dumpola in just this fashion... somewhere.

 

but as i stated above this happened a little after i shifted into second gear, everything was gravy in first gear, second shifted fine and about midway 2nd it gave out and sounded bad

 

Doesn't matter, it was the launch that did it. Metal fatigue.

Same deal as when a rod in a boosted setup folds in half at 3000 rpm cruise. People get confused, it happened at 3000 rpms and they weren't even on it??? The rod got a bunch of hairline cracks in it during abusive driving/detonation, but people are mislead that it didn't happen during a pull. The same concept applies here.

FYI, the car I watched bust it's diff did so on 8K launches on 22" slicks. It was scooting pretty well until that happened, 1.7 60' times.

Saying it happened on the launch is naive. It took a lot of abuse over a long period of time to fatigue the metal enough to do that. It's that, or one blunt impact (which the OP said did not happen).

 

Video of me doing exactly that damage to my transmission, carnage pics at the end:

Same thing happened to me, but i was not driving hard at all. I just shifted into 3rd and it exploded the same. The spider gear pin fell out and then it went boom...

 

Glad the axles are holding up, too bad the trans didn't. How do you launch the car? Do you preload at all? I wasn't killing trannies like that at 550whp with 25" tires.

 

i rather break axles than trannys or clutches. no axle upgrade for me, just stocks

Wheelhop maybe? I toasted a final drive and pinion gear last year when my car wheel hopped coming out of the burnout box.

That car does not wheel hop at all.. Hook and go!
