I think Josh did better than we know on that pass..... once past the 60 ft time, the new set-up gained hard at every increment. 6 hundredths from 60 ft to 330 ft, 4 hundredths from 330 ft to 660 ft and 5 hundredths from 660-1320.... and yet had a lower MPH, which is hard to do..... Its hard to gain et on a car in the 2nd half of the track, but yet run a slower mph.....it actually doesn't add-up, on my simulator, if you gain 1/2 tenth in the 2nd half of the track at 120 mph, (8.8 feet), that means you averaged apprxomiately 1.5 mph faster in that same distance... and yet his MPH is lower on the slip. Which can only mean, either the MPH timers gave a false number, or he let off the gas before the back stripe or at very end of the track detonation or fuel pressure dipped right before the end. Your timeslip MPH is the average MPH you ran in the last 66 ft of the track. Typically a car like Joshs is entering the 66 ft timers at 118, exiting at 120, thus will have a 119.0 mph on the slip. If there is a dip anywhere in their, the MPH will of course drop..... basic mathematics tells us this happened based upon the time he covered that distance per the timeslip. The 1000 ft et would have given us a better indication of how hard it dropped that last 320 ft. But who knows.... |
