    Dyno Results 328xi (Stock vs Modified+AA FLASH)

    **Had this posted on the "other" site. Figured a few here would like to see the differences in power when modifying certain parts on the N52 platform.

    Hey Guys,

    I had the chance to do comparison dynos on all the mods that I did on my car and figured this information might be useful for some folks looking to follow the same path.

    The difference with my dyno results is that I was able to do a baseline dyno followed by several additional dynos after adding mods.

    What you will see in the graph below are 3 dynos with the following mods:

    Dyno 1 (RED): Stock Ecu with Performance Intake+ Performance Exhaust
    Dyno 2 (GREEN): Stock ECU with 3 Stage Manifold + Performance Intake + Performance Exhaust
    Dyno 3 (BLUE): AA Stage 2 Tune + with 3 Stage Manifold + Performance Intake + Performance Exhaust

    One thing to note is that Dyno runs 1-2 were done in nice cold climate, 15 deg C (59 deg F), where Dyno run 3 was done in 29deg C (84 deg F) with 80% Humidity. With that being said, I reckon that I should be able to extract about 5-7 more hp and ft-lbs if the temperatures were the same as runs 1-2.

    Overall, I am very impressed with how my car has handled the modifications. The manifold alone definitely complimented my car even without a performance tune. The AA stage tune helped to smoothen out the 2 big dips that occur when the DISA actuators engage and also tweaked the AFR to get some more mid-range power.

    I have been working with an AA rep to tweak the car and this is pretty much the best we can get for my car (that makes sense). The blip you see in the later stage of Dyno run 3 was due to the wheel speeds registering different speeds on the front wheels and the transfer case locking the wheel to get them to rotate evenly.

    The way the car responds is definitely a massive improvement over my stock setup. The power delivery is strong and the throttle response is very sharp and crisp.

    The best feeling is when you pass 3500 rpm and the car seems to just pull really hard. One thing for sure is that these cars really run out of power after 6500 rpm.
    I have managed to run in line with an 2009 Acura -TL SH AWD (310hp) and both times I took him off the line and continued to open it up (beat him by 1.5 car length).

    As for modifications, this car is done and I have no reason to add more power. I am happy with where I am sitting at right now and just going to enjoy the car and maintain it.

    My car from the outside is pretty much stock, as I was never into cosmetic modifications. I was more driven with modifications that would benefit the driver (wheels, suspension, sports wheel, and performance modifications)


    Now here are some details on the car.

    2007 328xi AT
    75, 000km (46, 602mi)
    e90

    Enjoy the results and if you have any questions, please post them below.

    Dyno Comparison (All three runs)
    Dyno 1 (RED): Stock Ecu with Performance Intake+ Performance Exhaust
    Dyno 2 (GREEN): Stock ECU with 3 Stage Manifold + Performance Intake + Performance Exhaust
    Dyno 3 (BLUE): AA Stage 2 Tune + with 3 Stage Manifold + Performance Intake + Performance Exhaust

    Here are a few runs for each dyno did above (did about 3 runs per dyno)

    Dyno 1:

    Dyno 3:

    ****EDIT****
    Don't have enough rep points to post links of Dyno graphs.
    Here are the numbers, Once I get enough rep points, I'll post the dynos.



    Dyno 1 (RED): Stock Ecu with Performance Intake+ Performance Exhaust [awhp 195.7 torque 184.13 ft lbs]

    Dyno 2 (GREEN): Stock ECU with 3 Stage Manifold + Performance Intake + Performance Exhaust
    [awhp 212.3 torque 195.7 ft lbs]

    Dyno 3 (BLUE): AA Stage 2 Tune + with 3 Stage Manifold + Performance Intake + Performance Exhaust
    [awhp 216.8 torque 209.5 ft lbs]

    Bring over as much as you want.

    Not a lot of N52 love unfortunately, good to see.

    Yep. Unfortunately it isn't easy to obtain 335 type gains with an NA car.

    The key is to buy the mods at a steal deal, which make the gains more appealing.

    Thanks bud. Great talking to you and Zak.

    Also, has there been any updates on the tune since I got it? I am good friends with Bimmersport (AA hub) and if you are looking at tweaking a few things, let me know. Send me a PM if you like.

    Unfortunately, i didn't consider getting one at the time. I would guess that I would be about 5-8whp lower without the exhaust and intake.

    when its comes to n52 desi is the man. those of you who want a good bump in power should get the stage 3 intake manifold. its an easy project to do.

    slow - probably would have a similar dyno graph! Hopefully Cobb can help change that!

    Thanks bro. Couldn't have installed it without my asian friend and his little fingers :-)

    thanks bud, anything is better than the stock form it comes in so I have low expectations - will have to hit you up soon for some coding after I get the Aero kit put on...

    Thanks Dzenno.

    Yea you can see how hard the stock ecu is trying to keep the AFR on the lean side. BMW really tried to make the 328 a fuel efficient car.

    Hey Andrew,

    Are the AA tunes ok to run in cars where the temperatures are -4degF?
    I know colder air is better for the car, but their is always a limit.

    if you go with headers, would you keep the secondaries in tact or get rid of everything?
