Dynoed my 135i!

ajvee · 03-29-2010, 08:36 AM

Guys,

Last weekend, I took my car to be measured on the dyno (Dynojet). The entire experience was fascinating, as I've never seen a car on a dyno before. I just wanted to get a baseline and I am quite happy with the numbers.

Car Specs:

BMW 135i
Year: 2009
Transmission: 6MT
Mods: Stock
Miles: 3400

Thanks! Are you surprised that the VANOS event at 4.5K looks pretty smooth?

As a 2009 car dont you have an N54? N54s dont have VANOS.

EAS · 03-29-2010, 12:52 PM

Impressive numbers!

MFIZZLENYC · 03-29-2010, 12:54 PM

good numbers about 10 more hp compared to my 275 whp on a Dyno Dynamics and about 10 less torque though compared to my 295 hp...

This is news to me. Can you explain why the 2009 cars don't have VANOS?

Back when the n54 was first developed BMW decided that thy couldn't make vanos work with turbocharging.

The n55 is the first turbocharged engine to have vanos. The n55 only came out a month or so ago

You mean Valvetronic

VANOS has been part of the N54

ohh...whoops...nevermind then.

If you guys notice, the AFRs are pretty lean down low (15+). I think it is pretty interesting that a stock car runs that lean. I would imagine for safety, they would run a little bit richer. Then again, I am just learning about this stuff, so a discussion on this would be great!

Irishace · 03-29-2010, 06:35 PM

Really solid baseline numbers!

Smac355 · 03-29-2010, 07:33 PM

so what's the typical expectation for bone stock? I havent seen to many bone stock dynos for the 135i.

Winston Wolf · 04-01-2010, 04:02 PM

I would be more concerned with boost numbers than A/F. The car will do what BMW wants it to when stock. It's tough to get an accurate mixture reading with a sniffer behind cats. You need the wideband before them, so I wouldn't get too worked up with what they gave you. Did they take your boost readings?

Well I am not sure if this counts, but I saw about 7.6 psi of peak boost.

The BMW engine is a lean burn engine and intentionally runs lean for fuel economy purposes.
