I appreciate your input, I hear you, I understand now what rules dragy has but this is not a "Dragy," list.

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?

WOW!!!

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

The VBOX doesn't measure slope. Slope is a simple math calculation that was probably taught in math at about 4th grade. If Draggy were calculating slope differently, then I'd be asking what else is Draggy doing differently that might also not be valid?

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.

Unreal. On 23psi only, still turning it up till we see 6.4s.

I hold both records in 60-130 and 1/4 mile for Stock Motor and Clutches.

Very nice runs there. Congrats!

Imagine when this guy upgrade the turbo/s and fuel.
🤔

Can I get my 6.5 added to the list for stock turbos? Downpipes only.

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

16*. Were trying to get it to go to 17 and I would like to see more boost.

Nice, how “southern” are you in IN?

For this run, did you revert back to the OEM intake instead of the open CTS Turbo setup?

I did. Log testing shows OEM with holes cut and BMC drop ins to show the best MAF flow and lowest WGDC on average.

However with slightly lower boost levels.

That's gotta be one of the funniest signatures I've seen on the forums

The difference between no slope and 3 percent is over half a second. If that's doesn't seem like a problem when measuring ability to complete times something is wrong. The faster you go the more that negative slope of 3 percent actually assist your run. I don't have to submit files to see that as I've visual watched it happen. When I broke in to the 6s 60-130 I ran a 6.9 no slope. For shits and giggles on the same road just 1/4 mile earlier at the same air intake them during the same night. I hit the down hill that was 2.4 slope and cut a 6.4. Why people seem to think that's a small amount I have no clue. If you were seeing a 11.0 and 10.5 run down a drag strip the difference is multiple car lengths. If you would like I'll go take a photo and video of that road you can with out question see difference in height even at night. But as said not my thread I won't belabor the point.

It's definitely nowhere near "over 1/2 second." I had the owner of vboxtools.com search the database for a 60-130 that's nearly identical to yours, but also has a -3% slope. Then I had him resubmit the results using the timestamp correction feature.

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."

It's not a problem because those are the rules. You don't get to change the rules to suit your own runs. Since you already know where that -2.4% slope is, I'll bet you've already run that same spot with your new setup and didn't break 1/2 second off your time. If you had, I'll bet you would have posted it here because you already know it's a valid time according to the rules in play here.

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.
