Should've uploaded this here.
The car has: Steinbauer tuning box (claimed 430bhp) Forge intercooler (new) ITG panel filter Fabspeed 200cell DP M-performancs Exhaust Here is the graph. 5th gear pull. 2 runs, one with tune box on one with it off. Intercooler on first run was steady 40deg C second run was also same until the last 1000rpm and temp went to 60deg c, timing pulled about 8 deg and a drop in power. So, across the range the power was about 35-40 engine hp and torque was massive. On the road I think it would be different at the top end, probably gaining 15hp. Anyways I'm happy with stock and tune. Not sure why it died on the last 800rpm but it is what it is. |

And yes, i can flash to stock, but with a catless dp, they are not truly stock baseline, they would be baseline to the tune only

Yes STD reads higher not denying that, but also has less correction and more of a happy number. With SAE (American Muscle) mostly used, barely by BMW.

SAE is the industry standard. BMW's quoted numbers for it's US cars are in SAE. Correcting Dynojet numbers to STD will elevate the numbers about 4% above SAE. If you dyno, you should correct to SAE. When one reads a dyno plot, they should definitely factor in how the numbers are corrected. Plot smoothing also comes into play as well.

At the end of the day Baseline + Tune in SAE is the same Delta as in STD with maybe 1whp 1wtq difference at least in my case.

Excellent thread. Looks like with only bolt-ons, there is still a good amount of power that be be extracted out of the "maxed out" N55 that some initially called it.

The stock turbo is essentially maxed out, not the engine itself.

Yeah I hear you. But it's nice to see guys are getting around 40hp increase and tons of torque from bolt ons. Being a car of balance, I don't think the M2 needs much more than that. Of course, many would beg to differ.

So I have a thread going thought I would post in here to.
Stock dyno 354 whp and 388 ft lbs I have another session coming up soon with my mods Vrsf dp, vrsf street intercooler, fabspeed muffler bypass, BMS intake, and jb4.. so it should be interesting. I'm going to do a couple pulls on map 0.. with jb4 turned off. And than a couple pulls on map 2 in jb4 To see the difference with and without jb4 |
