Its automatic, well i use that dyno quite often so numbers are +- ok and its crank power not whp so its sad abit Runing it now for about 6 mounths
Will flash transmision in a days also

[E92William]

Well idk what to say then regarding it being crank horsepower because then it was corrected with god knows what correction. I'd wanna see wheel horsepower numbers it gave out and compare them to the ones in that thread. If the correction was done right and your car is running perfectly then it should show 255 or so crank corrected

based on that graph, I don't think your DISA valves are working. The torque curve is wrong, there should be a torque peak near 2500rpm, and another one at 4000rpm.

This tune is identical to the 255hp tune on the 330i, so if it's not making the expected power, it's not the tune. That said, 225whp is not far off from the 330i, but the torque curve still looks like a DISA valve is malfunctioning.

Found a junkyard 330i, 2005. Not quite local so might have to ship it, but decent price.

Any issue fitting it's intake manifold to a 2007 328i? Or can I check by VIN?

And I know it's probably answered here already, but man this is a long thread.

Few things you want to check with that that manifold being that it came from a 2005 330i (I would hope an e90)

If it indeed is an early 05 manifold it most likely will have a single port pcv hose connection at the bottom instead of dual like the 328 has. So you will need to cut up a hose to make it fit on to your valve cover outlet since you wont be using the stock pcv thats outside the manifold on the 330 as your 328 has it integrated in the plastic cover.

Another bigger deal is the disa valves, what revision are they? If they say 928/929 it would be highly recommended to change them as those have weak hollow shafts and tend to break, but either way if they are actually that old they probably wont work anyway when you go test them on inpa, which you should do to save yourself the hassle of changing them later

Here's a picture of a single and dual port manifold next to each other for some context on the ports.

[Tacklewasher]

Thanks.

I found it on a parts lookup system, so can't actually see it. But the pictures did include a VIN, and from that I can tell it's a M54 engine, and the part # for that is 11617525753, vs what I think I need being 11617559523.

Found one on Kijij for $350 Cdn, but would have to be shipped.

I need to be sure I've got my engine leaks fixed first.

[E92William]

You want to make sure it is from an n52b30. An m54b30 manifold will not work for it. And the first part number shows the e46 m54 manifold when searched up

Yeah, the one from the junker is a no go for me. That's the M54 one.

Still thinking on the Kijiji one.

$350 with a solid small DISA and large one has play so will need replacement or rebuild. Plus ~$50 to ship. Picture shows both PCV connections as well.

I've already ordered the cable from Bimmerlabs and set up an account.

Pretty sure my leak was the vavltronic thing, so that's good.

I installed a 3-stage IM on my stock '07 328i wagon last week. Intake and DISA valves were sourced from a salvage Z4 via ebay. Prior to the swap, the engine flowed a peak 23.2 lb/hr through the MAF at WOT in 2nd (~232 crank hp). Operating conditions were 36 degrees F at 100' MSL on 91 octane.

Post swap, the engine flowed peak 26.3 lb/hr on the same day in the same operating conditions, indicating a gain of ~31hp (263 crank hp). Of note, the DISA vales operated as advertised using the original tune (KB# 7612318 dated July 1, 2010). MAF graphic attached below.

This weekend I got around to re-flashing the ECU with the Bimmerlabs 330i tune. Once I got that chaotic near disaster ironed out, the engine flowed a peak of 27.1 lb/hr at 68 degrees ambient, which corrects to roughly 27.7 lb/hr at 36 degrees F (~277 crank hp). Overall, I assess the intake and tune to add approximately 45 crank hp.

On a 32 degree day, with 255/40/18 BFG Comp 2's installed and traction control off, my G-tech pro recording several 0-60 runs of 5.9 seconds by pinning the throttle and spooling up the torque converter, releasing the brakes just prior to braking the tires loose (DTC off). Initially I didn't believe these results, so I subsequently tested both my 911 GTS and G55 AMG, and the readings were consistent with actual time-slips and manufacturer figures, so I trust it.

I conclude that the intake and tune are excellent upgrades, the sport wagon transfers weight better than my previous 330i manual sedan, and that the auto trans gets additional power down more effectively than a manual.

[E92William]

400 is a lot for a manifold with a bad large disa and a small one that you don't know if it works or not. Should haggle him down but a lot.

Those are awesome numbers if they're true, now that makes me want to see what my MAF reads as flow because I honestly have never checked it or logged while doing a pull, my car has headers now. This is definitely one of the best upgrades for these cars

Agreed. I paid $190 to some guy in CA, and the intake came with both (working) DISA's. In fact, it looked like a brand new part. The car must've been near new when it got totaled.

Also, take care to get the correct manifold... it looks like some could have different vacuum hookups on the bottom (1 vs 2).

Agree. The final numbers in my post are corrected to 36 degrees F so I could compare the result to stock baseline. At standard ATM it would probably be closer to ~268 crank. It would be neat to see what it actually pulls on a chassis dyno, but I didn't baseline the car before the swap so it's OBE.

I've always used the conversion: 1 lb/hr = 10 crank hp. It aligns close enough to dyno pulls * 1.15 drivetrain loss. The conversion tends to get messy if you run any power adders, especially a supercharger.

For non-euro market cars I actually prefer using the MAF reading. If the engine is running stoichiometrically (i.e., not popping a bunch of O2 sensor codes) then you get an excellent idea about how much the air pump (i.e. engine) is really working.

When corrected to HP I see you made 226.6 rwhp, or ~266.6 crank hp given 15% driveline loss.

I just did the same conversion to my car, and according to MAF in lb/hr I got 268 crank hp at standard ATM. That converts to 268 * .85 = 227.8 rwhp, just one hp difference from what you realized. Pretty consistent!

[E92William]

I should have probably done that with the stock car to see. However outside temps here are ridiculously high sometimes, today it's about 85F so I think I won't get numbers as high but I also live at sea level so might make up for it. Going to try using torque app

Huh.

It's about $200 cheaper than any I've seen, even without valves.

I'll keep looking.

Excellent work and Kudos for logging.

Are you sure about the air flow data units? My N52 recorded about 700kg of air per hour. My N54 started at 950-975 KG/hour and it's now running above 1,100 on my own tunes.

Of course the N54 does not has a MAF sensor so the airflow is calculated.

When I have manifolds on hand I sell them for 315 with reworked disa valves. So I don't know who's selling them for 600 because if that's the average asking price I'll have to make some updates to my margins lol. Talking USD though I realized you're in Canada, not even pitching my stuff just saying

Also have to make sure you're not getting something from a 325 2.5 or something like that since they had those in Canada, the runners are smaller even if it looks exactly like an n52b30 manifold. Definitely check in different places, that guy must have smoked a candle

I forgot who it was here that has a pcv hose made from a hydraulic line, probably a 3/4in or something similar. I think could easily be done to fit the single port to the plastic valve cover.

Supply up here is pretty small. But to buy off Ebay is $150 in shipping, so it does kinda balance out.

But our buck is getting stronger, so US one's are, effectively, coming down in price.

Excellent catch, Rjahl! The units should be lb/min, not lb/hr.

[Tacklewasher]

So, I'm planning on tackling this. Have a manifold coming, a K Dan cable stuck at the border and downloaded all the software.
Is a silicone intake boot a good idea? Or a waste of money?
I'll check out my starter while I'm in there, but it hasn't given me any issues so if it looks clean, I'm not fussing with it.
Do I need to disconnect the battery to do this? Reason why I ask is this is a PITA on the convertible. If I touch the starter, I will, but otherwise? Video's I've seen don't show disconnecting the big battery cable.

If the cable comes soon, I'll try the tune first. Still reading up on it.

THanks
