BMS Stage1 Track Times!!

BMS took their new M5 out to the track for some test runs and I figured I'd share the results here. The car is a 2014 M5 DCT with 400 miles on the clock. Fuel was 91 octane with 3 gallons of 100 octane mixed in. Mods are the BMS Stage1 tune, K&N drop in filters, carbon filter delete, and they tested a couple combinations of an air box mod they've done.

The best runs of the day are below. They had the least amount of wheel hop using comfort shocks with tire pressure lowered to 30psi.

Note on the 11.49@126.72 the VBOX file when loaded in to the vboxtools.com site reports a 11.52@126.67. So the VBOX can be very accurate if you use the proper site to authenticate the file. It must average the last 60' of the traps as a real track does rather than using absolute speed. Also note the authentication program allows up to a -1% slope although most real tracks are going to be closer to level. Obviously doing runs on a higher slope will result in inflated numbers compared to what you would get at a normal track. Using the VBOX also allows you to do testing in conditions where most tracks would not be open. Like in the middle of the night, etc. So take VBOX runs with a grain of salt but if using this vboxtools.com site to authenticate the file they are as close to real times as you can get.

Nice runs!

The difference between the vbox and the drag strip time is all in the roll-out. The way I stage at the track I have a roll-out of 1.3'. If I deduct that 1.3' from the vbox raw time (without any rollout) I am usually spot on.

Great runs to BMS!

If you submit the files to vboxtools.com like Terry did above, the software will do the 1-foot roll out and calculate NHRA trap speed as well. However if you use the readout of the vbox itself, you don't get this feature.

In the comparison between vboxtools and actual timeslip above, I see the following correlation:

60' : 0.026 second difference
330' : 0.024 second difference
1/8 Mile ET: 0.018 second difference,
1/8 Mile TP: 0.478 MPH difference, 0.5% error
1000' : 0.010 second difference, 0.10% error
1/4 Mile ET: 0.001 second difference, 0.0% error
1/4 TP: 0.605 MPH difference, 0.4% error

I had one car at the event with three vBox's attached. PBox, Video vBox Pro, and the new 20Hz vBox Sport. I have all the timeslips to compare vBox results. It will be interesting to see if the 20Hz vBox Sport increases the accuracy of the vboxtools.com comparison to actual timeslips.

Let's keep in mind he isn't using launch control, so even with current setup he should be able to shave some time off.

Are these tunes detectable by the dealer or can you take them off without an electronic footprint?

400 miles on the clock? The engine is not properly broken in yet. Can we do that? it seems like a lot of stress for the engine...

Ran my 2014 M5 with the BMS tune today. Akra exhaust, Gruppe M intake and BMS Stage 1 (+3Boost) with 93 octane. Im running 21" wheels/tires and I didnt deflate the tires at all. Just wanted to run the car as is. I had 1/2tank of gas too...Im happy with the time considering I didnt have to do anything but show up and race. I didnt use launch control, I just feathered the throttle. I had a few runs with better trap speeds of 125.22 but this was the fastest run I did.

Yeah, your 60 foot is not good, but you are making power with about 4MPH over stock. Some better tires/20" rims/60 foot time and that that posted run could have been a 11.2 or 11.3.

What he said. Lower your tire pressure to 25-26 psi and you can get a 1.85 60 foot.
