Put my M135i on the dyno today

[TLK]

So this morning I decided to take my M135i to KAR and put it on the dyno.

I have been interested to see for a while what the wkw would be after I installed an AC Schnitzer chip in it. I didn't however check what it was before the chip.
but
I asked the guys if they had put a stock M135i on the dyno recently, and they had. The power output on the last stock M135i was 210 wkw.

I was quite happy with the results I got.
The last run they did was 233 wkw.

Just out of interest does anyone know what 233 wkw equals on the fly wheel?

Here are some pics :thumbs:

Nice graph. 286kw on the fly

I think that is awesome result with the chip. :thumbs:

 

[Rommies]

very very very nice graph bud. you are going to give a lot of cars a hrad time with that power range. :thumbs::thumbs::thumbs:

raise: really nice graph! and good power for just a chip.

Nice! Excuse the dyno noob but according to the graph would best shifts be at around 5000 rpm?

Well done. Good numbers with just a chip.
What does the chip cost?

286kw on the fly from 233wkw, never. You can work on a +12% loss not 22%..maybe for an NA but this is a turbo application. Good power btw, grapth looks very smooth..

Calculation was done with an online calculator. And takes into consideration altitude, turbo or na and which wheels put the power down.

Still 22% is not correct. I did 194wkw Stock, by that calculation my stock N54 does 240kw on the fly..It only does 225kw, or at least that is what BMW says. I'd be doing 350kw on the flywheel with that calc.

Good figures and very nice graph!

congrats very nice looking graph smooth and keeps peak power into the high rpms:thumbs:

You got to take into consideration where the revs will drop in the power band on the next gear and work it out. Its hard to do this with that method only as the car may drop to a decent power range but the rate of acceleration might drop because its a higher gear. Best is to use a Vbox and log the G's the car is pulling in each instant.

Turbo applications still suffer at altitude.

And really you want to compare your figures to bmws quoted figures. Go look at that 328i plug and play comparison that was posted recently.

Good power Shane dynod my car there a few weeks back it made 216wkw stock running shell fuel.

So ACS gain is about 17wkw give or take

Good stuff !

:thumbs:

Thanks for the reponses. I am also very happy with the way the curve turned out. :joy:

I did a bit of research about the wheel kw to fly wheel and it seems like 15% of the wkw is a good number to add.

@Quick///M - I will have to put shell fuel in next time :thumbs:

hi bud is your car auto ? ive got a manual and did 212 wkw and 459 nm at Kar on pump 95 (stock ) for some reason the auto have less wkw and nm,nice graph how does the car pull ,have you tried to race a stock m135 ?:thumbs:

 

[Dean ///M]

What gear was the car dynoed in?

The car is indeed auto and I haven't actually raced against a stock M135i or any hot hatch for that matter!
Seems like they are all in hiding whenever I come out

I am not sure what gear they were in. Maybe like 3rd or 4th?
