He got some data logger info from Lee Beard for Steve Torrence’s 3.775 @ 328.38 mph run. He made some calculations off the time slip and the logger data.
They said the car was about 50 lbs lighter at the finish line than the starting line due to the fuel burned in the run. 2320 lbs min weight.
The highest G force is about 2.5 sec into the run. (4.8 g)
Time into run = 1 sec
Engine RPM = 7890
Driveshaft RPM = 2775
G meter (g’s) = 3.75
Fuel flow (GPM) = 60.7
Manifold boost (PSI) = 47

The time slip for the run:
60’ = 0.834 sec
330’ = 2.133
660’ = 3.034 @ 282.95 mph
1000’ = 3.775 @ 328.38 mph
The engines have some kind of ignition retard that acts like rev limiter at the end of the track.
Hale figured Antron Brown’s 3.071 ET was 10,100 HP.
I thought some of this data was pretty cool & amazing.
I rather see Pro Stock data, but I will take what I can get.
