Congrats, nice time.

And yes it should be totally legit as far as i can tell. Did you send the .dbn file to Mr.5?

Interesting how similar our cars perform. I can see from your sig your Vbox 1/4 mile time end end speed is virtually identical to mine, my best 1/4 mile time on winter tyres and a cold road is 12.4 sec @ 118.81 mph. There really aren't any drag strips where I live or even remotely close unfortunately.

Just broke my old 91 oct/meth record of 8.59 with this nice little 8.39 sec run.
Swapped my CM10/CM7 to a CM10/DO12 meth nozzle setup. Swapped in some cleaner DCIs also.

Heh I need to start the run on the decline like hotrod did. I bet I can get low to mid 9s doing that and stay within the 3% slope.

IMO 3% slope is way too much. Should be more like 1% tops.

I agree, 1% more slope is easily around 0.4-0.5 seconds on a 60-130 run so the difference from a 3% incline to a 3% slope is potentially pretty big.

But hey, it's in the rules, so go find a 3% slope somewhere.....

The initial slope is important to me, because during the launch at 50mph+ I am having traction problems with DRs, therefore anything to help in the beginning is crucial.

Agreed that there should be less of an allowable slope than 3%, but other people use it to their advantage, so you should probably do your best to maximize your results. Even on the regular non-dedicated flat qtr mile run, I can get in the 8's though. I think in this 1.4% slope range, in order to hit 9.0 or quicker, you will need a car that traps at least 123mph in the qtr mile on the vbox...level run. Mine is clocking 125mph on the Vbox now for a level qtr mile run.

I don't even know if I can find a nice 3% slope around here, lol. Wish I could.
FYI: My 6.95 sec time was a LEVEL run. Can't imagine if I did a 3% slope in that car. But let us know if you can quantify the advantage of a 3% slope. If it is significant, then I may have to go and find a new test area. I have a feeling that at higher speeds, with aerodynamic factors, etc, the slope may not help as much as you would hope.

I ran a 10.59 60-130 on a +0.02% slope so that would be more indicative of the cars true performance.

Sure I can go back to the same road where I pulled off the 9.8 and make sure I don't pull until I am on the actual decline instead of going 20 feet on an incline before going downhill. I bet I could cut low 9s with that approach.

These 60-130 numbers need to have slopes or graphs reported otherwise they are severely tainted. The more experience I have with the 60-130 the more I believe these numbers don't mean a damn thing. Also 60-130 doesn't factor in for gear shifts either, considering I have to shift twice to hit 130 as opposed to those with manuals or taller than stock wheels. The metric itself is broken, sorry.

I should try a vbox quarter mile at the top of this road as well. Bet I could trap 124 full weight.

I think we should have a 60-90 or 60-110 database. No traction issues, easier to do and make it a 0.5% maximum slope. Takes the gearing equation out of this as almost everyone will do a 60-90 or 60-110 in one shift tops.

What do you guys think?

It would be nice, but unfortunately this is the standard that was already set by most of the forums. So to be competitive, you have to use the same factors to your advantage. But yes, if everyone on here wants to rerun theirs on a .50% or less slope, I will do the same! I think the most obvious correlation you are going to get is between trap speeds and 60-130 times. The cars with the best trap speeds are going to have the best 60-130 times too. And no....my 125mph traps that I am getting pretty regularly now are not going down the same decline..they are within the same level parameters of most drag strips. So really what we should be doing is posting our trap speeds on less than a .20% slope. That would be a better indicator of your cars acceleration capabilities.

I'd be cool with that. The road I used for quarter miles and trapped 118.9 with traction cut has a altitude variance of less than 2 feet. That's gotta be as fair as it can get.

Gonna retest again at lower humidity though. These runs were done in 81% humidity.

Yup, this lower humidity has been working wonders. I really think that is what limited me to a 123mph Vbox reading at Sac with that 85-90% humidty. I have been regularly trapping 125mph down here lately. Did you get a 60-130 time when you ran that 118.9 qtr mile? Whenever I do a qtr mile run, I just go to 130 since it comes up pretty shortly after the qtr mile pass is done.

Also, why is it that people don't post the the elevation graph on the side of the acceleration graph? I always do, since it is an important factor in comparing runs.

No because I'm handicapped to two shifts 60-130. Even if I did it would likely be in the high 10s. Didn't shift into 5th on the quarter mile runs.

I'd do the same if I had a Vbox. Anyone without one measure their 60-130? If so, how?

I do like the idea of 60-130 runs as traction becomes much less of an issue. I also believe its easier on the car.

Same thing here, initial slope is the most important.

Agreed. I just did a 10.7 sec run (in 4th gear - no shifts) last week going slightly uphill (0.4%), so at speed, wind is probably more important than speed. I usually test 100-200 km/h and on the same level road results can vary up to 1 second going either one way or the other, depending only on the wind (less than 0.1% slope/incline). But all things equal, I can typically pick up 0.4-0.5 seconds for every 1% more slope (evenly distributed slope i.e.). I would imagine a really steep slope for the first few hundred feet and then a flat piece would be even better.

Now of course none of this makes the car any faster, so it's only good for "winning the contest". As for a useable, comparable database for current and future mod-addicts, the maximum allowed slope should be as low as reasonably possible.

Some other food for thought those calculating minds out there.
So lets says the slope is determine by how much rise/decline there is over a certain distance (run). What if someone simply went down a steep 18ft cliff at the beginning of the run. Does that extra 18ft of going down hill get picked up by the GPS, as measured distance? Or does only the horizontal direction towards the finish line count? Or maybe a slight combination of the two. Is it possible the distance between start and finish may be longer than what the GPS measures if you are on a slope? If so, you may be cheating yourself out of some distance traveled by running on a slope. Maybe someone that knows exactly how the GPS distance calculations work on the Vbox can chime in.

The vbox guys have been at this for a while now. The performance box is just a small bit of what they do. I would venture to guess that the slope is only calculated for the factual run, so if you do a 1/4 run, then it calculates the 1/4 and if it's a 60-130 then only the distance that takes up that run is added in. It would not make sense to add any time after that, weather it's acceleration or deceleration.

Just a guess though, but it makes sense

Well, here's my 10.7 sec 4th gear graph, including height curve. The incline is 0.41%. It's quite impressive how linear the power is and a damn fine time for a FBO non meth for just using 4teh gear I think

11.96 seconds, felt sluggish even though meth was spraying. 90% humidity so I'll be watching for a better night and do some logs on JB4.

Congrats you guys!

JPSimon,
The only run that I have from you is the 11.35 run.
If you have the better run then email it to me.

Gents these runs were done back in mid October and I just forgot to send files to Mr5

9.07 60-130mph

Below is the link to my thread and also the description I first posted.

http://www.e90post.com/forums/showth...ghlight=60-130

Finally got my hands on a vbox and did some runs tonight in Mexico.

I have a 2007 6at e92 with 52,000 miles on the odo. And I'm running Map4 on the newest at the time Stg3 Aggressive procede beta maps at the default settings (65% boost/100% IC on map 2). Shifting with the paddles at 6000RPM. Starting to accelerate in 3rd gear around 40mph. Then upshifting twice at 6000rpm.

I did 3 back to back runs. All recorded in the same log file. My times were 9.07, 9.19 and 9.30. I guess even meth cars aren't totally immune to heatsoak! Each run had a decline of less than the 3% max allowed. I'll email the vbox file to Mr.5 for verification and to double-check my math. Still running full weight (although I have a carbon fiber trunk lid). I think I can break into the 8s if I did some basic weight reduction (seats out!). I have a procede datalog of a 8.9s 60-130mph run but it turned out that the decline was -3.5% I've attached both the vbox log and the procede datalog if anyone wants to look them over.

The biggest difference with these new maps compared to the previous maps is that boost is lower (17-19psi peak dropping to 14-15psi by 6000rpm) and power between 5000-6000rpm is ridiculous! Low end torque is amazing too. When I was starting the run in 3rd gear at around 40mph, I would even get serious wheelspin that sometimes lasted until past 60mph . I think just going with some stickier rubber would help. Oh and it was a nice cool night mid 50s.

List of upgrades:
Procede rev.3
Vishnu PWM Meth (80/20). Also added 2 gallons of 100oct to 2 gallons of 91.
AA catless dp
Vishnu cat-back (but added high flow secondary cats)
Helix FMIC
Vishnu DCI
Forge DVs

All seats in the car
