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.
