During my first two track days last year (after adding the T28) I had 2 of the studs break off and all the bolts backed off. I added a 2nd stud and used a bolt but these kept backing off after every 20 minute session... I got pretty good at tightening these while the car was still hot
.
This was what it looked like Friday night when I pulled everything off. The heat shielding on the water/oil lines did it's job, all the rubber lines are still soft and look the same as the day I put them on there.

The damage, two studs broken off. The two that aren't broken are so torn up that I can't rethread anything into them.

What the stud and bolt look like that where in there...

The dirty, dirty engine bay. If you look closely, you can see the melted plastic parts on the frame rail. This is what happens when you have a failing fuel pump and run it at the track

A trip to the machine shop yesterday yielded me this. One stud is still broken off, but now has a extractor bit broken off inside it. The rest have all been redrilled and threaded for 3/8" course thread.

All the new hardware, hardened studs, grade 8 nuts and some jam nuts.

I don't think things will fail this time. I double nutted what I could. Also, I am building a bracket for the DP to the tranny. I finished most of it up last night and will finish it later today once I get the DP back in and verify the last set of holes at the DP bracket.

Any thoughts on how I could do this better, let me know. I was wanting to pick up the hardware for drilling the nuts so I can wire tie this, but was to busy to do it. Maybe on the next setup
