35is Dyno'd

Dr Stig 2 · 10-14-2011, 10:51 PM

Guys & Gals,

Had the Z4 dyno'd this morning with the local guys from the 1Addicts forum.
2 Z's turned up.
A 35i and a 35is. I didn't hang around for the 35i but...

Below is the Dyno chart from the 35is - making 215kW at the wheels. (Multiply by 1.32 to get flywheel)
In comparison, at the wheels a 1M made 219kW and a stock 135i made 187kW.

Dont try to convert the N to Nm. Its just there for show.

so what's that in hp s?

Dr Stig 2 · 10-14-2011, 11:01 PM

Multiply by 1.36.

Which hp?
I have quoted you metric hp.

215.5 kW comes out to 293 Hp at the wheels, or about 380 Hp at the crank.

Very good baseline dyno

I disagree with that last statement. Most manual (or DCT) drivetrain losses I've heard are in the 15% range, that's 345 at the crank.

But a good showing none the less.

Good show!! I wonder whats making the 1M run that little bit stronger? Manual trans with less loss?

PS: Seems like BMW underrated the Z4 35is slightly.

how can this car have 380hp at the crank while bmw claim 330 think you speculate to much! try to be objective.

Here's the link to all the info including graphs of all the cars dyno runs:

Actually, I don't speculate. The multipliers were the claims of the dyne operator.

But, if it was only 15% I'd feel ripped off because then I'd be getting less than the 250kW claimed by BMW.

At the end of the day it is what it is.

drop a Jb4 in there

my z4 35i baseline (IIRC) at 287wtq, and around 286whp
then with Jb4 Alpha (first DCT N54 to get tuned and dynoed with a Jb4, maps have improved now) I got 351wtq (IIRC) and 349 whp. it's been almost a year, so do forgive me if I'm not exactly right, but I won't be off by more than 3-5 whp/wtq

I for my 0-60, but I think it was 4.2? 4.3? I only did it twice so I don't remember.
