Default Went to the dragstrip today. (protip: don't go to the dragstrip.)

First run, I wheelhopped badly at the launch, missed 5th, and still went 13.9 at 98mph.

Second run:

yes, i was actually talking about you at the track last night, were hoping his R & P didn't get into the torsen itself like yours did a few months back.

Maybe you'll luck up and something didn't break. Maybe your broke the R&P and cracked the case, but your torsen survived, or something like that. I have a few questions for you about that rear end so maybe others can learn. Did you install the torsen in it? What backlash and preload were your running? This isn't what I want to see as I want to weld my rear end...

Yep, I think drag racing is harder on the car than just about anything. That launch is so abusive, yet so critical. I say you pick up an open 1.8 rear and weld it up. Then you'll have your drag racing rear ready to bolt up.

+1, that's what I'm doing. Something has to fail for the diff to go. Usually one thing fails, like the ring or pinion, then that blows up, gets in torsen, breaks it, then binds up and cracks the case. Key is figuring out what breaks first. If I weld my diff, it will never break. R&P is known to be the weak link, so setting that up on the tight end of spec or tighter will save it. FWIW, minimum backlash for a 1.8 diff is .0039. I'll be doing mine .0030 or so.

I like your reaction:

"I'm going to go buy some parts."
Track guy: "Yep!"

man, that sucks. my dad just blew the 1.6 open in his miata (stock power mind you), and it sounded a bit like that.
