N55 TOP SPEED THREAD: What is the top speed you have achieved in your N55 BMW?
Hey all,
I figured I would start more of a “fun” thread here. I searched around and I saw an older top speed thread in the general (non-BMW) section, but nothing specific to F3x or N55. That thread was just people posting how fast they have been in various cars, but it was mostly non-BMWs, and I am curious for our specific platform/engine. The question for this thread is simple: What is the highest speed you have achieved in your N55-powered BMW? It doesn’t necessarily need to be an F3x, but must be N55-powered. Doesn’t need to be within a ¼ mile or a given distance, just overall maximum speed you have achieved as a driver. I believe the forum has a policy against street racing stories, so let’s not go there. Top speed runs are assumed to be done legally. Some details to include:
I will start:

I've buried the speedo before. I'll call it 160 bc I don't know the actual speed, but the needle did pass the 160. This thing pulls like a monster all the way to the top.

147 mph readout on the HUD…still pulling when I crested the hill, then hard on the brakes down the backside sweeper right turn towards a stop light.
2014 435i xDrive M-Sport, MHD Stage 2+ E20 map, VRSF intercooler and catted downpipe, M Performance intake with drop in filter…sounds pretty similar to OP's car.

I achieved around 189 using gps I don't believe the dragy tracks speed far as I know as. But you know our speedos maxes at 160 and the digital speedo maxes at 162. I believe she got a lot more I ran out of road. I'll try to get a log and overall video of the run. Goal is 200

Fully stock 2015 435iX F36, original owner did not spring for M package so engine cuts power at 210 km/h (130 mph). I manage to hit that in the last 10% of the main straight at Pacific Raceways. Speedo indicated 132 mph, GoPro and Harry's agree at 131.
