MHD stg 2 - any bolt-on mods or is your M2 stock ?

That would be 358-360 to STD smoothing 5. Pretty high for the bolt on stock flash. Curious to know what MHD can do on top of that.

Curious for the results as well.

That's about right. UltramaneticAl did 375/390 w/ bolt-on, no dp and no tune....

I see a trend of inflating M2 stock power numbers in past few months as more people are reporting 355-360whp 2017 winter numbers, which is some 30whp higher than the first few bone stock samples dynoed in mid 2016.

Granted M2 is very sensitive to ambient temp thanks to its insufficient intake air cooling from factory. But the 30+whp difference to me are just outright absurd, that's piggybacked FBO PWG maxed out on E30. No mention Dynojet already compensates pretty aggressively for ambient with STD/SAE/DIN correction.

I speak with real world experience. Below are true whp numbers on 93OCT to STD correction for all N55 variants, already pretty optimistic Dynojet readings;
EWG
M2 - 335~345
M135i/235i/35i MPPK - 300~310
335i/435i - 275~285

PWG
M135i/235i/35i MPPK - 285~295
335i/435i - 260~270

Bolt-on mods on stock flash do negligible to peak power, unless stock IC heat soaks on dyno machine.

Accept it, for many reasons, N55 is an inferior platform in term of making 'clean' horsepower. Supplemental injection and flex fuel are defined as dirty stuff in my book.

No matter how important the 400whp bragging right means to entry level modders, I can safely conclude, with proper baseline as such, no N55 stock turbo can achieve it on pump gas till this day.

Which is why a lot of us went with an upgraded turbo. A stage 1 is perfect....minimal turbo lag with that extra punch up top, being able to wring it out N/A style.....all for only $1000.

So what would those numbers be on a mustang dyno?

We're fortunate enough to have both a Mustang AWD and
DynoJet 2WD dyno at our facility. There really is no straight
conversion for comparing DynoJet-to-Mustang power figures,
but I think our HEX Tuning ///M2 Master Thread can help to
shed some light on the difference.

Specifically if you jump to Post #37. ← (click link to jump)

When calibrated properly, the delta gains demonstrated by
both dyno plots are nearly identical, despite the significant
difference in peak power figures. That's why we always say
that chasing (or focusing on) a peak value is the wrong way
to compare vehicles or products, and you should instead be
focusing on delta gains and area under the curve.



More info on reading/comparing/tracking gains can be found
on our "♒ TWO Dynos - HEX Tuning ♒" thread. ← (here)

I disagree as per my post on this thread

http://f87.bimmerpost.com/forums/sho....php?t=1496455

2016 M2 on stock tune with the right bolt ons can yield good gains

Stock 369/400 power/torque at crank
Same car on same dyno with just Fabspeed DP 393/420
Same car with DP as above and intake hardware changes 424/440.....

Thanks those links have valuable info. Great points!
