A few recent acceleration tests

Tomorrow my car goes under the knife to get the new ACT carbon-carbon clutch installed.  I'm so busy this summer that I don't think I'll see her back until September.  So before I take her in, I decided to go out for some 60-130 MPH runs.  Nothing really spectacular, not trying to set any records -- just having a little fun to see the car's performance.

All runs were performed with very heavy 20-inch "Power Eating" wheels, and track-shredded bone stock Michelin PS2 rubber. No drag radials; no middle of the night runs in 40 degree weather, at sea level, with a negative density altitude.  For me, it was just the following conditions:

Time Temp(F) RelH Press(Hg) Alt(ft) DA(ft)
9:15 - 10:00 PM 82.7 38.3 29.45 172-302 2285

The real performance zealots make fun of anybody running 20-inch "Power Eating" wheels and tires on the car.  Just so I gave my car as little advantage as possible, I'm running wheels that weigh 1.5 pounds more than HRE P40's.  (That comment should make the little mindless nazi's at SS-Post go a little crazy.)  The tires are completely track-shredded bone stock Michelin PS2's.  The rear wheels and tires weigh in at a whopping 54.5 pounds.
