Chris's dyno chart from Memphis
Here is Chris's dyno chart, he emailed to me to post
Looks like either the boost is not holding at 5000 rpm or the flash is pulling back timing at 5000. The drop at 5000 is more dramatic than it appears on this chart as the scale is so compressed with the airfuel chart taking up a large portion of the page.

Addition of Race Gas
Just by adding race gas no other changes since my gas had ethanol.
My boost was a constant 1.1 to 1.2, which may still be his issue.
Notice the drop at 5200 in where the timing is pulled.
Blue line is very similar to Chris, Red line is after adding race gas, no other changes. Flatten this chart out and it is very similar to Chris's

Car does not compare to my 92'

Christian, You need to get that car to someone you trust to check it out and maybe do another set of runs. You're not getting enough air to that motor, or you have a boost leak issue. My clutch was horribly slipping on me and I had bad misfires two weekends ago at the track and I was still outrunning 450-500HP cars on the track in the straights, and my setup is identical to yours...

Mikelly sounds like you needs some new FR6LDC's and Kevin's GT3 Clutch Kit, installed mine a week ago, love the Clutch and LWFW!!!!! I'm sure you have read about that clutch, and it is all true.
The issue is already being addressed. Shop that's replacing the clutch is also updating the plugs to the correct version, and I won't be using that GT3 clutch... That's what I already had and killed in 500 miles, Along with a GT2 PP... I'm going with the 999 PP and the 6 puck ceramic clutch.

Good idea Mike, that's what I have and it's survived 3 track days, about 40 1/4 mile passes, and maybe 20 or so VMax runs. Starting to soften a bit, but still holds strong.
Will be interesting to hear your feedback on the drivability - the grab point takes some getting used to. You going with a LWFW also?

Kevin, I recommended that Robert contact you. I suspect he didn't. We're going with the 999 and the ceramic and I hope I have no further issues... The car was back together on Friday and they're trying to get it aligned and back to me by tomorrow...

Nope, the gauge in the car was reading 1.1-1.2 bar
