Does it seem that the FM provided studs and nuts don't have the problem and BEGI's do?

I don't believe the "longer on the loud pedal, faster driver" theory. A setup with 2* less timing and slower driver would have higher EGTs, and a slower driver on a track with a longer straight would stand on the gas longer than Sav.

I made my speed comment because I've seen a direct correlation between the speed of the turbo car and the occurrence of this issue. The guys who do 1-2 track days a year, full-weight street cars on street tires, never have a problem. The guys who are on r-comps, doing 6+ events a year, and actually going fast, have the problem. I recall VagaXT commenting on how he never had the problem, and then he showed up to Streets in December with NT-01s, laid down some stupid fast laps - and struggled all day long with nuts and studs backing out.

or maybe you're just driving like a *****. Seriously. Do you go out there for blood or to cruise around and "have fun"? I go to the track because my mother never loved me and I never met my father, and now you have to ******* respect me or I'll wear your face as a ******* mask.

You said you were within 3 seconds of the GJMS record, which was (I presume) set by one of the FM cars. I don't want to sound like a dick here, but I know how fast I am in comparison to the cars that are 3 seconds ahead of you. I came very close to rear-ending the **** out of the Westfield exiting turn 6 at Laguna in March. I don't think there was an FM car within 5 seconds of me.
3 seconds on a 1-minute track puts you around 10-12 seconds slower than the cars we are talking about here. Certainly a respectable time, but not really on the same page as the cars we are discussing here.

Since I haven't tracked this year yet I'll use my last years experience.
My manifold is a custom 45deg/topmount SS log, 3" SS downpipe, no gaskets, no leaks(machined flanges) with a 2871 and I was using shitty bolts everywhere.
I was shearing studs like I was cutting disco in 79', winning or in the top 3 at every track event up here (I know that's not saying much really), so I beat the **** out of the car quite often but I'm sure my problem was my exhaust system and the amount of pressure/weight that was acting on the turbo system.
The exhaust is a full 3" system with magnaflow muffler (mild steel), has a flex pipe right after the dp and weight to much imo.
I eventually broke the weld and the turbo inlet flange right in half after I sheared two bolts and keep going, vibrations ftl.
This year I'm running a v-band at the dp-exhaust system, arp bolts, and I'm rehanging the exhaust and using different hangers (rubber garabage sucked and move to much) and that should fix my issue, I hope.

Still waiting on details of new build.
