2002 330ci Dyno Results

[NightWolfe]

Had my car dyno'd about a month and a half ago, but I finnaly got my hands on the WinPEP files so I could get the proper graph .. but anyway ..

Car is stock except for my Kpeng special exhaust :)

We only did 2 pulls, so I had them do the first pull in 3rd and the second pull in 4th

1st Pull - 3rd Gear:

Temp:106.13°F
Humidity:19%
Correction: SAE
Max Power:201.72
Max Torque:198.69


2nd Pull - 4th Gear:

Temp:105.68°F
Humidity:19%
Correction: SAE
Max Power:203.48
Max Torque:205.02

I'm pretty happy with it considering I'm not a ZHP and only have exhaust done .. plus the car had about 88k miles on it at that point ..

nice :thumbsup:
pretty good for a stock 330

[skipole]

Excellent numbers, especially in that heat.

[DJ Reminisce]

Good numbers, especially for 106 degrees!!!

:thumbsup:

Makes me want to get mine dyno'd!!!

[MJRMatt330]

nice numbers! its good to know that an stock 02 330 with decently high milage can throw some pretty impressive numbers! I wonder what mine can do with headers and an intake... :4ngie:

[NightWolfe]

Thanks guys .. that was at around like 1pm, and it was hot as **** in that garage .. that is corrected data though, which I beleive compensates for the heat, but am not sure .. need more mods now :)

[skang330]

wow nice numbers

[skang330]

Hey how much does it cost for a dyno run?

[NightWolfe]

A bunch of my friends and I had a "Dyno Day" .. I think we had 15 cars .. and we paid $40/each for 2WD for 2 pulls .. and I think the AWD cars were $45 or $50 for 2 pulls .. generally around here I think they do about $50-60 for 3 pulls

and thank you :thumbsup:

Not trying to thread jack

I want headers, just dont wanna get em if I have to remove them for smog :bawling:

That would make the performance aspect complete for me :banghead:

Maybe I'm just naive, but as another 2002 330ci owner, aren't we supposed to have 225 horsepower? Not 201, not 203, but 225? Where'd the other 22-24 hp go?

225 at the crank I believe, not to the ground

DO IT! I have got to see those numbers.

the 225 is BHP .. which is measured at the crank

the dyno reads RWHP (Rear Wheel HorsePower), which is what you are actually putting down after all the drivetrain loss .. I beleive about 15% is the average for a manual ...

so judging by my RWHP I would be around 238 BHP .. so I picked up roughly 13 BHP from my kpeng exhaust that everyone makes fun of because they are pissed they spent $700 on an exhaust :D

[wlmmn]

Ah, I see. Thank you for clearing that up guys. So, why don't auto manufacturers measure horsepower that actually goes to the ground?

Because higher numbers sell more cars, and the average consumer doesn't know the difference .. sad, but it's true

....soooo, you're saying you picked up 13 BHP by cutting off the muffler and resonators? :hmm:

Not knocking the exhaust, I was planning on doing that mod as well, just seems like that claim may be off a lil......correct me if I'm wrong

[zhp pilot]

what were the uncorrected numbers? what kind of dyno? i.e mustang, dynojet, etc.

[jamesthebikeguy]

nice brah

[skipole]

:werd: +1 - find out what kind of dyno you were running on as each type tends to have different results.

Also, I *highly* doubt that your exhaust gained you 13bhp. More likely, the drivetrain loss was less than 15% or the advertised crank power numbers were off.

Well .. it says "DYNOJET RESEARCH" at the top of the graph, so I didn't think I need to say what it was .. but it was a DynoJet ...

Uncorrected was 201.47HP and 202.52TQ .. my numbers would of course been higher if it wasn't 106° out, so the corrected numbers are probably pretty close to actual .. 2HP and 3TQ loss from heat sounds right, hell it could have been more ...

just picked up my 330ci the other day. Love the car. My other car is a 97 civic dx with Intergra gsr motor, turbo @ 9psi, hondata engine management etc. and that thing put down 320 at the wheels!!!! thats around 360 at the crank and the car weighs 1000 lbs less than my 330. I know you all hate hondas but damn does it pull hard. Thinking about making some upgrades to the 330 though, which engine management seems to have the least bugs for bmw?

[simsima325]

good numbers :)

i kinda want to get my car dyno'd, wish I had done a baseline tho when she was stock.

[SL Blak Soldier]

damn those numbers aren't bad at all. i thought we were running about ~190whp stock.

[NickG]

Here are the results from my 2001 330ci when it was bone stock.

Conditions were:
Temp = 92.5F
Humidity = 28%
Pressure = 30.45 in-Hg
SAE Correction Factor = 0.99

Thanks man .. I think my car may be a bit of a "factory freak" .. either that or my kpeng exhaust really does the trick .. I know it should since it's nice and free flowing .. Once I get my headers I'm gonna dyno again and see what my gains are
