E90 330i 6MT Dyno Results

A shop near me Vanku Autosports in Philadelphia was having a dyno day special this past Saturday. 3 Runs for $30. Figured I would see since I have been curious.


224.5 HP @5900 RPM
223.5 TQ @4100 RPM



Full Disclosure:
-No A/F Ratios were recorded
-No baseline Dyno since I am not going for performance with this engine
-All 3rd gear pulls Edit: I listened again and think it was 4th gear
-Dyno graph doesnt look like what Im used to- what was given to me
-2 other cars (Charger,370z) Dynoed what they were supposed to so I think it was accurate
-Ambient temp was 58 Degrees
-Car was driven 40 miles to the shop so fully heatsoaked
-93 Octane Sunoco Gas
-DTC was left on
-88,000 miles on the odo
-Hood was left open per the shops decision
-Apparently a Dynocom Dyno www.dynocom.net
-This was out of curiosity and for fun and in no way to start a war on here.


Mods:
-Injen Intake
-Cyba Scoops
-Muffler delete
-CKS Coilovers, SWIFT Springs
-Style 95 wheels
-General GMAX as03 Tires
-35psi all around
-Tint
-BMW perf. SSK

Those are great results. A bit high imho though. All the 330's in Houston dyno'd about the same but were tuned for 93. Probably has to do with 3rd gear pulls (why not 4th?).

I'd love to have more info about your suspension and more pics of your stance though

Not sure. I think they were all 3rd gear but now you have me wondering. Ill have to listen to the other videos again and confirm. I though they were high too but like I said the stock charger and 370z dynoed very close (+/-5 of where they should have been according to OEM which leads me to think the dyno was very accurate. Ill post some pics soon

Listened to the video again. Does in fact sound like he went to 4th gear. Not sure why I had 3rd in my head. Listen and you can hear him row through 3 and sit in 4th then go.

Dynocom runs between 5-10% higher than a Mustang/Dynojet in most tests. It would all depend on how each were calibrated. I know you said you didn't care about baselines, but it would have been nice to see the delta's from your mods.

Great looking 330i and good numbers. The more time passes, the more I'm sure that the 330i is kind of a closet classic in the U.S.

Power numbers seem plausible but the torque is very odd. 330i was rated at 255hp/220tq so it seems unusual that your power and torque would be essentially the same. Further, factory torque peak is 2750rpm and your dyno sheet shows max torque at 4100. Maybe their calibration is off for torque and on for power. Is that even possible?

I agree man would have been nice. I never had the motivation to spend $100-150 on a stock vehicle. The mods were gradually acquired so it was never a good time and seemed like a waste of money. Now I wish I had.

Thanks! The numbers did surprise me and everyone there. I agree they seem odd as well as high, but the Charger and 370z were basically spot on with their numbers which had me wondering. I was honestly expecting sub 200 numbers when it went on the rollers. I wonder if my intake and muffler delete have moved the RPM range where peak numbers are. Also had never heard of Dynocom prior, and wish the graph were like the typical ones im used to seeing from Mustang and Dynojet.

Anyway it was out of curiosity and for fun so take these digits with a grain of salt! Thanks guys.

Edit: For what it's worth, 4100~ is actually where it begins to pull and up to 6000 or so. Just in normal driving my power is right in that range.

Suspension is First Generation CKS Coilovers with SWIFT Springs instead of what came with them. I have it set to a ride height that is low enough but still daily driveable. Spring rates are:

Front: 336 lbs/in
Rears: 672 lbs/in

Ride is incredibly smooth and stiff at the same time. If I wanted to go lower I would need to roll fenders, the wheels are OEM Style 95s and are 19x9 and 19x10 et24.

Can you tell us where you sourced them from, did the swift spring come with the package? Thx

Bought the coils slightly used from a member on here- SWIFT springs were bought from Harold @ HPA who is also a vendor/member on here. Coils can be bought new from **********s.

Nice pulls man Good to see that thing still rocking at 88k. I dont think having a baseline is all that important in this case, with an intake/muffler delete. Although, would be good to know what the Z/charger posted for comparison purposes. Anyways, good ish!

Thanks yea the thing has been damn reliable. Still feels great. Ill see if anyone there that day has the numbers from those two. just remember they were incredibly close to what you'd expect stock for the vehicles and didn't seem under or overrated.
