C5, H & C, Stock CID, 10.77 @ 125 all motor Took a trip down to MIR this past weekend..... The weather wasn't as good as the Import vs domestic race but it was decent. I am going to calculate the DA here shortly. When we arrived down @ MIR it wasn't very busy being the last race of the season so I went through tech and let my car cool down.....
Weight: 3320 on MIR scales
Temp: 47
Dew: 42
Pressure 29.92 and dropping
DA = ~-560
First pass tires were @ 15psi
60' 1.61 (launched soft to check the track conditions and bogged bad)
Tagged the revlimiter on the 1/2 shift
shifted 6500
11.00 @ 124.9
Second pass tires were @ 16psi
60' 1.52
Bogged again out of the hole, launched @ 7k, shifted @ 6500
10.84 @ 124.9
Third pass tires were @ 18psi
60' 1.57
clean pass really bogged off the line
10.94 @ 124.6
Third pass tires were @ 14psi
Let the car cool down so engine temps weren't 200, the car felt good came out of the hole decent but bogged again
1.51 60'
6.8x 1/8
10.77 @ 125.8
Fourth pass tires were @ 15psi
1.58 60'

93 octane, the cam grind has soo much overlap/no advance it bleeds off alot of compression. Makes it seem like a 11.0:1 with a small 224 cam. I could have done the same thing with 11.1:1 CR and advance the cam 4-6 degrees like the cams come normally.
