Going on over a decade now, 60-130MPH runs started on 6speedonline, the rule has always been -3.0% allowable slope. Vbox and Dragy basically do the same thing, so it's still going to be 3%. The slope % has been debated to death, and now and then someone will chime in with the same concern you have. 6speedonline invented the list, it's 3%, always has been. FWIW a lot of smart, very experienced enthusiasts and the person who invented the list, who have reviewed thousands of Vbox runs, are fine with the -3% slope.

How does Dragy measure a slope differently than Vbox? How can a slope calculation over a period of 60-130MPH be measured in different ways?

This is amazing! GREAT WORK! Loved my E92 ESS M3, and you did this on a stock motor and clutch, very very impressive.

Regarding the 3% vs. 1% difference: that was debated, discussed, and settled years ago at 6speedonline. For standards, all sites use the 6speed standard of 3%, not the Draggy version of 1%. Accepting a 3% slope from Draggy would be up to DLSJ5 -- if he wants to use the 6speed standard. If you have a vbox and want to know how 3% vs. 1% affects the results, you can submit your files to perfdb.org, select advanced options, and enable "Correct the timestamps based on slope rise and fall." I think the difference is far less than you think. In a 7-second 60-130, a typical distance is 1000 ft. A 1% slope is only a 10-foot drop over 1000 feet. A 3% slope is only a 30-foot drop over 1000 feet. 30-feet over a 1000-foot run is NOT a steep downhill. If you were standing on the ground at the start, you probably wouldn't even see it. |

You're at 6.5sec with 23PSI?!? That's killer. How many degrees of timing are you hitting up top?

Before: http://www.perfdb.org/vBoxFiles/ID00...060-130MPH.jpg With timestamp correction: http://www.perfdb.org/vBoxFiles/ID00...060-130MPH.jpg Difference: 0.203 seconds (nowhere near "more than 1/2 second." Quote:
Your comparison on the same night is irrelevant. I ran 12 consecutive back-to-back 60-130 runs on the same F82, all within 20 minutes, all on a perfectly flat road, and I saw nearly 1/2 second difference on a flat road on back-to-back runs. Run #2: 10.791s @ -0.242% slope. Run #6: 11.242s @ -0.385% slope (more slope, nearly 1/2 worse time) My second best time of the day was 10.808 seconds, and it ran slightly uphill. So your comparison is totally invalid because the variance can be greater than 1/2 second even on the same flat road at the same exact time. If you want a better time, go play by the rules, beat your own time, and resubmit your results. |
