My mods are what I listed. I’m just here to share, learn and help. As stated, the weather was ideal for my quickest run and the awd gives me a good jump off the line.

I did buy the car used, so the previous owner could have done something in the 3 months they owned it that I am unaware of, but if you look at my logs (as posted over on N54tech) there is nothing special about them.

What isn’t shown in a singular time is the variability throughout the night and from one night to the next. Two runs before the 11.639 run I ran an 11.85, two runs after I ran an 11.87. My mph varied between 113.15 to 116.59, with my second fastest mph coming with my slowest time ET. The slower times are more typical for what I run.

Perhaps the previous owner installed a stage 1 turbo upgrade? It would look stock from the outside...

An ewg car has a turbo with bigger compressor wheel compared to pwg car. Its just a bit smaller than stage1 turbo.

I have a pwg m135i rwd. My pbox tests with st1 turbo i could go high 11's @ 121.x trap speed. So for sure a m235i with xdrive could run 11.x as well @ 119 with a good map6 and some E in the fuel mix.

I am planning some stage2 turbo pbox testing myself however the weather is not cooperating. So far best i got at 20 psi is a trap of 125.8. I need to move to 25 psi

Anything is possible I suppose, but that should show up in my JB4 logs
