    • A BMW X1 as a serious performance machine? Believe it, BimmerBoost member runs 12.1@111 in his X1 xDrive35i

      The world's quickest and fastest BMW X1? That would be BimmerBoost member paradoxical3 with his BMS JB4 tuned N55 X1 xDrive35i. With a JB4 G5 ISO, 40% E85/93 octane mix, BMS intake, BMW downpipe, and a Wagner intercooler he managed a very impressive 12.137@111.20 in the 1/4 mile. That's quicker than a stock BMW X5M/X6M at a fraction of the cost with just bolt on modifications to put the performance into perspective.

      BimmerBoost can not find a 1/4 mile timeslip anywhere with a quicker result from an all wheel drive N55 based BMW so this appears to be not only have the X1 overall record but the N55 xDrive record as well. Congratulations to @paradoxical3 for his results on the strip and BimmerBoost looks forward to seeing him break into the 11's which are just a tick away.

        paradoxical, Thanks to your videos, I just bought a new Mineral White 2013 x1 35i with the M-sport package and 19''wheels. haha. I should take delivery of it around Jan 6th. Excited!

        I have a Helix Intercooler that is for my 2007 335i. Do you know if it will fit the x1? I wouldn't mind the normal trimming.

        Sounds like it may be a generation 1. Check with Helix to see if their lower charge pipe will work.

        I think you will need a different pipe. I know when I looked into it, N54 and N55 FMICs are largely the same except for the plumbing. Can probably buy one from them.

        I will check with them then. I have a gen 2, which was supposed to be completely bolt on, no trimming…but I alas, trimming was required haha. If a new pipe is all thats required, that would be cool.
