Manual, no slush for me.

I was super surprised at the result, was only expecting 160-ish like on the Shark Injector's plot. I haven't seen much info on the M-Sport package, if there's any changes beyond cosmetic (same exterior and interior as ZHP, Style 68 wheels) and sport suspension (including control arms). This dyno is a dual-retarder unit with load cells, not an inertial one like a cheaper Dynojet, but has had a correction factor applied to give figures that represent Dynojet results (so the kids can compare e-peens online). It's been pretty accurate with stock Japanese and American cars and trucks, when you add in estimated drivetrain losses.

ZHP was only offered on 330s so you have a regular 2.5l engine.
The car is rated at 184 at the crank, but Im not sure about the drive train loss on MT, but Im sure its less than AT.
Anyways, thats a pretty impressive number.

I8UrCat · 01-13-2011, 03:04 PM

I know ZHP was only for 330's, but the M-Sport package for the late coupes has the same M-Tech bodykit and interior pieces (textured aluminum trim, //M on steering wheel and shift knob and door sills, lighter grey faces on instrument cluster with different font, etc).

I'm at sea level, and the dyno is in a specially made dedicated room with high flow fans for exhaust extraction to the roof. Temperature in the dyno cell was about 2 degrees Celsius, same as ambient outside. I've got pics on my camera of the setup. I come from the VW world, and build my own race engines (I have a flowbench to boot), so I've spent lots of time on my friend's dyno over the years (and helping with his turbo builds). When I test drove this car, it felt a bit faster than the 2004 325i sedan I tested before it, and faster than lighter VW's with 175hp VR6 engines. "Under track conditions" I've hit 200kph/120mph in 4th gear with windows down and sunroof open.

I think the B25 with 45.1 might be underrated by BMW (to make the difference from B30 bigger). When I got my car dynoed (on a Mustang dyno) I asked if they had a baseline run for B25 and they found nearly stock 325 with similar numbers (178whp).
I'm a moron for not doing a base run before the SC went in.

I8UrCat · 01-13-2011, 05:59 PM

Yeah I've heard rumours of MS45.1 B25's running stronger, but didn't think the difference would be that much.

My stock A/F plot:

Stock is a bit on the boggy side of rich, leaning it out to a nice 12.5:1 would make a difference.

Iceman00 · 01-13-2011, 08:31 PM

Usually, 13.1 is better.

I8UrCat · 01-13-2011, 10:47 PM

Yes it is, however I'd like to keep some detonation resistance. I've never been a fan of relying on knock sensors. 13.1:1 is great for the dyno, but not for the street or track.

13.1 is fine for both.

This is interesting. I wonder the specs of the cams he used? ...264/248?

Thats a very good increase, but thats also a california car. Is it a super ultra low emissions engine?

Looks like a B30 with M52TU running gear

BimmerFerret · 02-07-2011, 07:32 AM

^ That actually isn't bad at all for those mods.

But why is he running an M52 intake manifold

I read the thread in his link and I think he has the 2.8L engine.

Then why is he calling it an M54B30?

Me neither. M52 intake and Vanos delete?

Actually, he is quoting someone else's car, so disregard what I said
