Still looks like the dynapack is a little high. The numbers from the dynapack at 16psi say he should be running 9.36 @145.xxx and he said he ran almost a full second slower than that on 16psi? Just saying that the numbers appear to be a touch high. Even if the track prep was bad and the MPH was skewed because of that its still not measuring up to the numbers it made on the dynapack. Like you said the 143mph takes 712rwhp, so even assuming the MPH was high that run due to wheel spin that makes the rwhp for that run also high. So one is safe to believe that on 16psi the car doesnt make more than 700rwhp. Maybe it does on 19psi?

You can base rwhp off MPH. ET comes with a dialed in setup, good 60ft, good prep, good gearing, all that affects ET.

Lets use example #2.. the 383LTX car. It weights 3620 and has a dialed in setup with many track outings. It dyno'd 701rwhp on the same dynapak. Then later ran 10.3 @ 135.2mph. Calculator shows at that weight and rwhp it should go 10.06 @ 135.3. Keep in mind its a 6speed manual car. I'd say its pretty damn accurate.

The calculator shows 698.2rwhp.. 2.8rhwp difference and .1 mph.
