Dyno results - low power 330i E93 2007

[Spook]

Hi Guys,

Went to a car show on Saturday in Midrand - there was a dyno test as part of the show so I decided to put the Beemer on the rollers.

My car is a 330I E93 2007 - 200kw version.

Car produced 110kw on the wheels. That's an extremely poor result from my assumptions.

The guy running the dyno showed me a few dips in power on the graph and said it was possibly the O2 sensors that are causing this.

Dyno is a Rightway Developments on Richards drive in Midrand.

What do you guys suggest I do going forward. Who would be the best person to assist me with getting this corrected.

Regards,
Sugen.

That dyno under reads horrendously! its a 4 wheel drive dyno if i recall. :hammerhead: Go to Kar or Fr&R it will give you a better indication of what you car is putting out and those are also the benchmark dynos in Gp :coolShake:

That's what I also heard. A buddy of mine has a G6 Gti and he put his car on the rollers. Car is stock and he put out 135kw.

If I use that as a benchmark then my car is definitely under powering or am I looking at this the wrong way?

Was very disappointed - car seems to be performing healthily - engine runs smoothly and no warning lights etc.

Maybe I must take it for dyno at one of the places you mentioned.

Definitively looking at it the wrong way, post a pic of the graph, looking at numbers doesnt give a clear indication of how the car makes its power. you could go one step further and find a few 330i's to harrass and see how you do against them in different scenarios :rollsmile:

Unfortunately he didn't give me the printout.

Car outran that same G6 Last Saturday on the highway - in sport mode - anything above 180 the Gold couldn't catch me.

Strange - going to take the car in for another dyno.

I'm just a bit concerned cause he showed me that the car dipped in two places on the graph and he says that's what the problem is.

Quick question - if there is a fault with the sensors on anything else on the car are the guys at KAR and FR & R able to diagnose and fix or at least diagnose ?

 

[Oldman]

There are several factors for a dip, the car slipped on the Dyno, the engine corrected the power, or the octane was not good enough, look at the graphs at the Dyno day. Secondly the correction factor may have been set lower than that of another Dyno. A Dyno is good to get an idea, if your car does not misfire on the road and behaves contrary to the Dyno, just take it as a measure in time all 5 seconds in the Dyno run and did they run a fan...

If you want diagnostics done speak to Gert from OBD Worx but as i said you reading to much into this. that dyno under reads like crazy and i have seen stock and healthy 135's make 150kw on it.

 

[Spook]

Thanks guys - feel much better.
Car goes well on the road - no backfiring and runs smoothly.
Runs pretty strong as well compared to other cars - even though its a concrete block ( it's a drop top)

If it truly puts out 110kw then it really is horrible. My e46 330 (170kw fly original)put out 113kw the day I bought it and it was in a horrible condition.

Go to FR&R or any other dyno and try again.

Please go to another Dyno place and redo it

If yours is only 110kw then what is my pre face E90 330i, 190kw doing.

Please go to another Dyno and redo it, pretty please

Sounds like the dyno is not being truthful. As for the dips in power, some N52's do suffer from some dips in power through the rev range, but you would feel them when driving and not "need" a dyno to tell you they're there (it will of course show you where in the rev range). I would go to another dyno and see if you can take a few 330i "friends" along... :rollsmile:

 

[spawn616]

tell jokes at the races you only make 110wkw,

then put money

then win then give that dyno centre number so you don't get harassed that you lied

:biglol:

I just want to step in here with another lane of reasoning:

Seeing that this model is a 200kw car at the flywheel, with the losses on the drivetrain, and of course due to altitude, and let's say some mechanical degradation, then take into consideration the heat on Saturday, is 110kw at the wheels really that far off??

Sorry to be a wet blanket, but I wouldn't say you could expect heaps more of power on this car. :sorry:

Fuzz remember that dyno from Zwartkops where you dynod the M?this is the sister dyno:hammerhead:

Highly unlikely. See my previous post. I had 113wkw when I bought my e46 330 and it was in horrible condition, from pcv to fuel pump damaged. I wouls say this one should be around 140 to 150wkw

I say 135wkw if the the E90 200kw 330i is stock, is abt the right number. Then again so many factors come into play that the result can be obscured.

Best is to run another similar on the road. Judging from the run against the G6 I don't think the OP should stress too much.

 

[spawn616]

well stock healthy e36 ms only make 135wkw at budler and thats depressing

but i would still own one and love it over my 200wkw plus honda,

dyno figures are just figures, if you really enjoy the car then numbers mean nothing unless it made 80wkw then numbers mean something

contradictory contradiction lol

Hi Guys,

Car really does run smooth. No misfire nor any dips in power that I feel when I drive.

Just for comparison - a F80 M3 made 190kw on that dyno on the same day.

So - ya - dyno not being very nice.

I will definitely do another dyno run and see what the outcome is.

Please keep us updated :rollsmile:

Noted Boss, but the E36 M is rated at 210kw and E90 330i at 200kw, so if both are healthy, the figures should be almost the same in my opinion. Unless u talking abt the 228kw or 236kw versions.

I too was very disappointed at making only 157hp/205nm at our last dyno day after making 180hp/266nm when the car was tuned.

But when I ran another friends Golf 5 GTI which I use as my reference, I realised that dyno figures were just that, dyno figures. All what matters is what happens on the blacktop ::coolShake:
