1/8 UnOfficial

We have a measured 1/8 mile road area that is used at times for testing (no this is not street outlaws) Had a chance to run the M240I x drive after installing the Dinan tune and Holy S--- First run was 7.8 sec and then a 7.7 -of course no way to know the MPH but the car just squatted and went - was pulling like a freight train all the way -brake launched right about 3K rpm in sport plus - I cannot wait until April 4th for our track to open - I will be first in line - based on compared 1/8 times on a 1/4 track that 7.8 would be a 11.8 or better 1/4 which is simply amazing - That is what my Camaro SS does and it has over 400HP at the wheels and is 200 lbs lighter with racing suspension-
The official time for our car stock which is posted on this site was 8.01 at 87.4 for the 1/8 mile which in itself was impressive

Good work.

The B58 may give you a little better top end, but based on my N55 data I wouldn’t be surprised if you land around a 12.0 second ¼ mile. I’m consistently in the 7.5-7.6 range to get an 11.8. Still really awesome considering it’s just a tune. The xdrive definitely rips out of the hole.

I went 7.9 in the 1/8 and 12.3 in the quarter with a JB4 only RWD M240i, so I bet you'll be close to breaking 11's, but I'd guess closer to 12.00-12.10. Bet the X-Drive is a blast to 30 mph. I can't get over how well even the RWD launches in both sport plus and DSC off. Launch control is too much for RWD.

Based on todays weather another 14 inches of snow - who knows when the track will open- but with over 28 inches of snow in less than a week - I am sure there will be some delays- as for breaking into the 11 - I still think it will not only because of being on a treated surface and also I will mix 101 race gas which on my last BMW N55 made a difference

Yeah, I'm in NY, near Syracuse. Winter will not let up. We're paying for a mild February.

11's definitely seem realistic with some race gas. Ethanol works great too.
