This will validate the power. Should be a low 7 100-200 with 480whp in a m235i.

100-200 7.5sec M135i - 420whp (500 crank, MAF 400g/s) - 1550kg incl driver

I presume that isn't dynojet whp?

My stock turbo n55 m2 run 7.9 100-200 on bm3 stage 2+ e30 map last year. Hoping its a little quicker after I needed fresh plugs and now i'm on 18's.

Rwd M135 is not comparable, absolute featherweight compared to the rest with the closest being the n55 m2 then the rwd M235, then rwd 435/335 etc.

There’s only 20/25kg difference between a m135i and m235i. You could make the difference up with a how much fuel each car is running.

Above harkes stated that a m135 (I am assuming auto and rwd) weighs 1550kg with a driver, a auto rwd m235 weighs a tad over 1600kg without a driver….

The kerb weight difference on like for like spec is 25 kg. Obviously different spec cars can vary the weight. I’d be very surprised if his car weighs under 1500kg without driver and would question how it was weighed.

I don't know where you got that mate. The the heaviest RWD M135 curb weight stated online is 1500kg, lighest being 1445kg. The closest m235 rwd spec to that is a barebones sunroof delete car with the 6mt and even that is 60kg heavier without a full tank of gas…

I think it’s pretty apparent the f20/f21 are in a different weight class.

Do you have a screenshot of that run? Would like to see.

Sorry, cannot find a 100-200 with my current setup, but here is an older one running BM3 BEF + JB4. And a corresponding power graf.

I had to dig these out from a 2017 Facebook post as my account for my Pgear has been reset. See if I can get a new time soon.

harkes · 10-27-2021, 07:48 PM

I believe my cars curb weight (RWD, Auto) is 1470 + 70kg driver = ~1550kg. I dont calculate weight of fuel.

My power numbers align with official power numbers of similar performing cars + VirtualDyno and PerfExpert. No - those are not "bloated" Dynojet numbers.

Wish they brought the 1 series to the states would sell my 2 in a heartbeat. That weight is incredible. What was the slope on that run?

WOW. nice build

3.0L · 11-20-2021, 10:23 AM

Interesting topic, boosting an already pretty powerful engine.

From what I've read at Dinan, they claim the stock 2014 M235i N55 engine actually makes 340 HP and 336 lb./ft. of torque - slightly above the factory claim of 320/330.

I'm very happy with the stock performance, so not interested in modifying my car. Runs great, no CEL's, etc.

What were the mods when you running that time and 420whp was the dyno'd number?

Mods in my signature

500 crank is the number from PerfExpert.
