2012 xDrive50i w/Dinan - 1/4 Drag Experience

[Diversified Returns]

Last fall I bought a 2012 xDrive50i with 48k miles....just added a picture of it to the Official Picture thread.

I believe it has Dinan Stages 1 - 4 on it (including inter-coolers and exhaust).

It is a blast to drive, and yesterday I took it to the 1/4 drag strip in Fontana, CA.

I went 13.84 seconds and trapped at 102.96 mph (with a .397 reaction time).

This seemed 'slow' to me - I thought, based on other posts, that I should run in the mid 12s?

Also, could someone please tell me what the specs are for my model X5 with the above mods? (it was 400 hp stock, but I'm wondering what the modified horsepower and torque numbers are)

Thanks
