    Help please - How to drag N63 vehicles

    I have a 2012 X5 50i Mpackage with Dinan Stage II and just picked up a 2013 550ix which the dealer through in Dinan Stage II.

    My question is, what is the best way to drag these cars.

    I've managed a 12.9 last year in 90 degree weather in upstate NY at NYIRP with traction off, erc off and in sport mode. Short shifting manually with the paddles at 5200 ran the identical time but 1mph slower. This was with run flats which made it to 10,000 miles and are now off the car.

    I do notice turning off the DTC and disabiling the DSC actually makes the car unstable at speeds, especailly on the shut down and highway.

    The 550ix has the '13 Sport + mode which strangely enough says it turns on DTC. Deactivtaing the DSC also makes the car unstable.

    I just turned 500 miles on the 550ix and plan on going to a dyno in a month or so.

    Thanks for any tips.

    My car is 6MT and not xDrive, so I can't give you any tips from experience but I have seen evidence from others that suggest that the DTC settings do not make a measurable difference. I guess traction is not an issue with xDrive.

    You might want to try launching from 2nd gear, as 1st is really short and these cars have a bunch of torque down low. Will save you the time of 1 shift in your ET.

    In all honesty, anyone can drag race that car. It takes very little skill to do it right.

    You get to the line, you put your foot on the brake, another foot on the gas, and just let the brake go and mash the gas when it goes green. That's it.

    With all wheel drive and all that weight on the X5 traction is no problem.

    On the 550xi, same thing.

    Let the transmission shift, leave it in sport, and keep DSC off.

    lol, and I was worried about coming off as offensive to xDrive/SAT drivers with my response.

    Thanks, but it was more or not the electronics (DTC, DSC) whether or not to brake torque, short shift at 5,500 rpm, auto trans vs paddle shifting, etc. I figured I could save some experimental runs with that knowledge.

    Thanks.

    Sorry for the delay posting.

    F10 550ix 12.47 @ 110.9 best time in upstate ny with crap track.

    Mustang dyno - 386 /468 max - on standard dyno 403 / 490.

    Assuming 20% drivetrain and diff loss Dinan is giving it good power.

    X5 Best this year 13.1 @ 109.4. Exact same dyno on mustang dyno which reads low.

    This is with Dinan stage 3 and the AA exhaust? Trap speed seems low - my best trap with just stage 1 was ~113. Another member was putting up pretty consistent 112's.

    xdrive/SAT combo is great for some good ETs though...

    I ran a 12.4@116 back in march before I got rid of my 550. That was leaving in second in sport + paddel shifting at around 6200 and with 305's on the back. But mine was velos stage zero and made 44xwhp.

    I'd like to see a time slip with a 116 even with a rwd car. That would be roughly 70whp more based on the weight of the car.

    And no the Car is stock aside from Dinan Stage II. Everything else is stock.

    Also the dyno numbers are done on a mustang dyno. Roughly 13% lower on this awd dyno than a standard dynometer. The mustang loads the weight of the vehicle as others do not. They simply load the weight of the drum.

    On a standard dyno mine would probbly hit 440hp.

    From what I read the rwd cars are about 3mph quicker on quarter but lately due to the fact the 60 ft in the ix is almost always quicker.

    Ive never tried launching in second. I'll give that a shot. Does it allow you to brake tq in second?

    This guy was pretty consistently ~112 with xi/SAT.

    Every track is different - the NY track is typically 2-3mph slower than the ones I go to in MD/PA with my other cars. This car hasn't seen any other track. Works been crazy and I've been spending too much time on the road to do a weekender.

    I haven't seen any 550's ix trap higher than 112 with just a tune in my neck of the woods or even the rwd.

    I'm sure the fact it was 38 degrees with a 43 relative humidity gave some help to his turbos.

    Mine was at 81 degrees and 70% humidity. Upstate Ny summers lol

    Just noticed the other car trapping in the 112's swapped his run flats. Good for atleast 1.5mph pretty sure as the PSS's are typically 8-10 lbs less a tire.

    They were 14 lbs lighter on my GTR in 20's.
