Stock dyno result :(

Chwali · 04-25-2018, 05:22 AM

I have M2 LCI manual LBB with 4k km on her. She's stock, but I wanted to check her on dyno just to see how "healthy" the engine is. To be honest I am more than disappointed. It's the first time I hear that stock engine in M car (not M engine off course) is low on power comparing with catalogue figures. We did 2 runs, 5th and 6th gear. See the dyno chart below.

Now I started thinking about power upgrade. I heard some good opinions about racechip box.

What do you think?

Why are you disappointed? That is HP on wheels right?
Then in my book it sounds right on track...
As for tune I would have a look at bootmod3 or simular, and not go for a chip.

The guy on the dyno said it was the engine power not on wheels. Otherwise I wouldn't even complain about it here.

Correct me if I'm wrong but unless he pulled your engine out and put it on an engine dyno it can't be "engine power"

M2C_PLUS · 04-25-2018, 07:46 AM

Torque looks good

DanG · 04-25-2018, 09:41 AM

Has to be power at the wheels. The figures look good.

Tell the dyno guy he is drunk!!

tutankhamon · 04-25-2018, 10:35 AM

Lol how on earth can he measure engine power from a dyno while the engine is in the car??!

Be happy with those numbers.

Lukeni · 04-25-2018, 10:52 AM

In europe its common to measure the power at the crank by multiplying with a loss factor. Since the nm is right where it has to be i assume its upscaled to „at the crank"

4fatsnake - its common in UK/EU for dyno's to give at crank numbers - evolve's dyno's for their m2 posted on here http://f87.bimmerpost.com/forums/sho...42&postcount=1

~ 308 WHP

~370 flywheel or CHP

OP's car appears to be down on power but that might be due to a number of different factors.

I'd ask about the tuning software. It may be out of date. From what I can tell Dynatech is on at least version 6, and that image shows version 3.5.9 possibly from 2004.

Also is odd that the name fabryka is on your image and also their website image. Leading me to believe you got the test done by directly them themselves. So, if true, why different software?
