M135i aftermarket mods and results

Just realised I'd been rather remiss and not actually posted any of the results from my tinkering with my 2013 N55 M135i...

So in short I will say that the car was dyno'd at Surrey Rolling Road in the UK along with several other 1-series cars a couple of weeks ago. They use a Dyno Dynamics RR in shoot-out mode and this is usually a very stern and honest piece of kit.

The standard M135i's (and those with BMWMP exhausts) made the correct and expected numbers of around 325hp, 330 ftlb

I was very happy to achieve a rather better than expected 394 hp and 450 ftlb

Performance mods on my car (so far) are a BMS JB4 running Map 2, full Scorpion decat downpipe and exhaust system, Forge Motorsports intercooler and BOV, Birds/Quaife ATB diff

As you can see, there aren't that many mods on the list so far and I have several more in the pipeline -including a Forge charge pipe, Forge intake and then the addition of water/meth injection should hopefully see me over the 400 mark,,,
