im not posting this to scare people or to talkshit... just wanted to share my badluck. if you dont believe me on the count of the launch or the burnout .. i cant do nothing. i dont beat the car like an ass or dropping the clutch at every stop.



really not my intention

 

My (semi-educated) guess is that the traction compound in the burn out box, combined with a 5k drop, is what broke this particular diff. CKit had an entirely different type of failure, due to entirely different circumstances, but both failures come from extreme conditions that most of us would never encounter. None of the guys who do regular burnouts would ever run throug the burn out box because they know this kind of thing is a possible result. I'm not bashing Warneck, but he did make two mistakes (both of which anyone else could just have easily made), and I'd really like to think that in his sharing he WILL help save a few people's differentials. I just don't want people drawing incorrect conclusions from this kind of incident. We need to understand what happened, and why, so we can avoid it, and it's NOT just a matter of the car having been launched hard and breaking.

Warneck, I sincerely wish you'd talked with me, Billman, XViper, or one of the other guys who have been driving an S2000 hard and doing burnouts for years now, becuase I really think this incident could have been avoided, and you didn't have to avoid the drag strip to avoid the problem. In part I blame the wankers, for constantly muddying the water and confusing people. Anyway, this could have been avoided, and I'm very sorry it happened. Next time, avoid the burn out box, and make sure you can break the tires loose cleanely when you drop the clutch. It is better to drop at 7 or 8k and get insane amounts of wheel spin than it is to drop at revs that are too low, because if the tires don't break lose cleanly, the diff takes a beating. It might also be that the car was abused and ready to break before you ever got it, but the burn out box and 5k clutch drop was still not a very good idea. I wish you could know how badly this kind of thing makes me feel, not only because it sucks outright, but also because I have to believe it could have been avoided.

If I were in your shoes I'd try to find a good used differential and swap that puppy out. It's not really that hard to do or that expensive, but it's still a shame that you're having to deal with this. Good luck getting it all sorted out.

 

No bUEno!! that sucks bRo..

 

Red, you having a bad day?

Chill out a bit will ya.

 

thats y ive posted and will update this tomorrow or wednesday when the diff is gonna be open i really appreciate your help your post make all sense thanks for the tips and now i know who to ask for more technical question :
like ive said before :
[QUOTE]3 run before it was my turn , the guy have put some VHT and thats y ive not launched higher... i think its a part of the problem.

 

i will take some pictures tomorrow.Took me 2 and half hours to put down the diff and put the other one... was pretty easy.started at 6:30 pm ended a 9H -9h10 beside 1 bolt of the propeller shaft stripped everything went fine. thanks too xviper with his how to

now the result: 2 cap broken, at least 6 teeths broken on the gear.1 cap was cutted in 2 and it was free in the cover when i open it (the left one) and the other one broken in 2 pieces but still in place.

 

Yes.

Anyway, I've got about 88k on mine and I've auto-xed heavily since I bought it with 15k on the clock.

 

I guess I'm a wanker now.



It's called freedom of speech. We're just posting incidents that happened. Other people can take from that what they wish.



Here's the tooth broken off my 4.57 pinion. The stock bits of the diff were fine. The LSD was fine.

It's possible to launch many, many times without breaking anything.
But you have a higher chance of breaking this part than some of the other drivetrain components.

That's all.

Seriously guys, don't we have better things to do than get riled up over the downfall of S2ki and the diff police?

 

Did you preload the car before dumping the clutch? I know that people with FWD High HP hondas Break axles constantly if they dont preload the car properly before launching, Just wonder if this was done or if pre-loading the car could prevent the rear diff failure.

 

Last friday i was at the dragstrip with my integra and there were a couple of s2s. I did witness one of them doing a burnout and then breaking his diff. God that sound was bone jarring. I think the problem here is heat. You do the burnout and the diff gets VERY hot! Then you go and launch on a very hot diff and CABOOM !!!!! It should be noted that both s2ks were only pulling off 15 sec passes .....they cant drive worth a dogs ass!!!
