HP and Torque gain from the following mods
Hello all,
What would be your guess on gain from the following mods: 2014 F32 N55 PPK: I was told it would net me 35 HP. Is this true? What about the torque? MPE: ??? Fabspeed catted DP: ??? Thank you.

From my understanding though, that doesn't NECESSARILY mean +50hp net gains, right?

MPE: Likely no gain at all Fabspeed catted DP: Probably heavy throttle closures and CEL without an aftermarket tune. |

No, fabspeed or HJS downpipes don't throw CELs, have an HJS with no tune and it's great.

Not a single CEL since august 2017
It feels great but i have not logged throttle closures indeed, do you have a suggestion to check this? I have a Bluetooth obd connector but no proper app, and JB4 is gone. I’m due for a tune in a couple of weeks anyway, but still interested in getting data on that |

Unfortunately I did not do that. If you are interested I do have dyno numbers with Dinan stage 2/3.

Even if we assume your car only loses 10% from the crank to the wheels, your dyno figures still suggest around 350/350. For the sake of discussion, if we go a step further and assume that bmw underrated the n55 stock hp/tq in the f30/32, and it's actually around 320/330, a 10% drivetrain loss still puts hp/tq gains at the crank at approximately 30/20. I believe bmw claims you can get +35/20 at the crank from mppk, so even assuming a mere 10% drivetrain loss and 320/330 stock, you still got close to the figures they claimed you could get from their tune. I'd imagine that it's certainly within the margin of error inherent in dyno runs, and extrapolating calculations like this. |

yeah that's what I thought too it seems to peak early. 1st pic is with Dinan Stage 2 and 2nd pic includes runs with MPPK, Stage2 and Stage 3.

BulsaraF36, you avg’d ~316/318 on your three runs. If they were both autos and similar DA, dynos and fuel, you could us his as a baseline for yours, so an increase of 19 whp and 11 wtq. I saw Dinan used 12% hp and 8% to estimate drive train loss at peak. That would mean raichean baselined at 333/334 and youre at 359/346 for a gain of 26/12 with MPPK+MPE, a bit underwhelming for the price if you’re considering peak gains alone.
Of coursw, using another car on another dyno in a different location is quite a leap. Using the same Dinan efficiency, your stage 3 setup is ripping a whopping 424/390 brake! |
