I just got back from my trip and here's a brief recap -- but before I start, I'd first like to thank everyone who responded. I don't appear to have the residual line pressure problem, BTW.
I left Indiana and headed eastward to Pittsburgh to visit friends there. Due to construction in the city, I was detoured from my intended exit and ended up driving off course, through extremely steep hills and small towns. Stopping and starting on hills evidently ate a bit of the clutch material, as when I went to full boost later that evening for another test, slippage was only very slight -- a big improvement over stock performance. I presumed then it would continue to improve, and I was right.
I ended up stuck the next day in rush hour Washington D.C. traffic on my way down to my test pilot school reunion. For about 90 minutes, I was moving the car about one car length at a time and stopping. I got off the beltway at one point and drove through town, where I encountered things like intersection gridlocks that took six traffic light cycles to clear. People where I live in Florida think that WE have bad traffic! It's nothing compared to Pitt and D.C. Anyway, my clutch got an incredible workout that evening of stop-and-go driving.
So on the way home to Jax I did a couple of high-boost runs on I-95, plus my reference standard (the Buckman bridge arch) when I got back to my home stomping grounds. Result? No slippage whatsoever. It holds like a vise! I made my last hard run in redzone boost on the bridge going from 70 to 125 mph, and had a rock steady tach, tracking all the way.
Incidentally, Jim... max boost appears to be altitude-related after all. I get noticeably farther into the redzone down here in the swampland than I did up there on the high plains. You were right.
Oh, and don't use Bigfoot gasolene! I got a tank of that junk on the way up I-65 to Indianapolis and I think they put 87 octane in their 92 octane pump. Could definitely see a difference between that and the tanks of gas I bought later in Pitt, Pax, and Florence, SC. (Still averaging well over 30mpg on the trip!)
The bottom line is that the new clutch is working as advertised now, after a couple of days of city driving to wear it in. I'm declaring victory, sending my old flywheel back to SPG9 now that I'm home, and am a very pleased SPG9 customer once again.
