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)

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



Detailed AFR for Dyno Runs




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

Dyno 1:
Stock Ecu with Performance Intake+ Performance Exhaust



Dyno 2:
Stock ECU with 3 Stage Manifold + Performance Intake + Performance Exhaust



Dyno 3:
AA Stage 2 Tune + with 3 Stage Manifold + Performance Intake + Performance Exhaust

Awesome post. Have you got a chance to run 0-60 after modifications?

Thanks.

Unfortunately, I never thought of taking a 0-60 vbox run stock. If it helps, I can do a 0-60 run with all my mods and post it (have to borrow a v-box from a friend). I should have taking a stock 0-60 run, but forgot about it.

How's the BMW Performance Intake you got? Is it worth getting? Any noticeable gains or sound with that?

[Spensaur]

Extremely informative post, thanks for sharing!

[pupa]

Very nice info!! How many miles did you put on the AA tune/manifold when you dyno it?

I love it. You probably get a few hp, but not enough for me to really feel it. There is a deeper louder sound but not as loud as the AFE.

I got it on a a sale price which made it worth it for me.

Thanks. I notice a lot of graphs were missing baseline dynos which kind of missed the point when doing a comparison against a stock and tuned file on the same car.

Thanks!

With the manifold installed, I put on about 1000 miles before hitting the dyno. For the AA tune, I put on about 1000miles before hitting the dyno.
Gave it enough time to adapt to the modifications.

Great thread and results! For an XI you've got some good gains and numbers going on

Thanks Des for this post! Congratulations on the gains and being happy with your mods.

216awhp! Nice!! I can really feel the disa valve turn on in my car too, but it doesn't happen when you're constantly accelerating / driving hard, the dyno isn't good representation of actual power curve in the real world, unless you swap from granny mode to hard lol

[MonsterM]

Any idea what would be the hp/trq difference, if any, between a RWD and Xi model on the same dyno?

all things being identical, AWD clasically uses 5-10% more power... soo 10-20whp at least.

[engotski]

Awesome!

Nice work, and results!

I'm just outside of my warranty now, so I'm looking into sourcing a 3-stage manifold and the AA swap. I'll have to have a chat with you on who the AA rep is that you worked with (I'm also in GTA).

[accel]

Interesting. This visualizes the dip reported when 3 stage with no software is installed.

[BoogeyMan'sBMW]

Congrats bro, lookin good!

Where u from desi bhaii

[MonsterM]

How bad is the linear power delivery affected by the AA tune and 3 stage manifold in day to day driving?

[mapleridge]

Desi any plans for primary and secondary delete? That should be 15-25 HP.

[3002 tii]

Nice to see proper dyno showing true deltas. Not bad for auto + xi.

Thanks bud for the comments. Took some time, but it was totally worth it.

Thanks bro. Have to be happy, cause if you are always trying to be the fastest car, you will be very dissapointed and miserable.

Although the dyno shows it, under WOT you dont really feel it. If you feather the throttle and work its way up in the rpm, you feel this power kick in (not a jolt of any type). That is my favourite part TBH.
The AA tune does a wonderful job of shallowing out the 2 dips to keep that power running strong over a longer period of time.

On this dyno, I have seen an rwd get about 10whp more over mines (same mods).

Exactly! Definately have more loss in power due to the addition of the transfer case. But the TC is very helpful when it comes to launching against an RWD
