No 128i Love :(

You aren't going to eyeball pressure wave velocity, pulse timing, or any of the other multitude of factors that go into proper header design.

These discussions really need to be divided into two categories. Those that remove the cat in the headers, and those that do actual R&D into a performance header.

I know it's hard to believe, but Super Sprint doesn't have a monopoly on header calculators.

You can deterimine proper primary lengths, collectors sizes, angles and scavanging effects by putting in valve timing events, bore and stroke and cam size. The reason SS and these headers look similar (and probably function similar) is because the data they input was essentially the same - the execution would be where they differ. I can't imagine that a production SS header based on the same data would have a 1 5/8" primary and while the Schmiedmann would have a 1 7/8" primary (nor do I know) but I feel confident that they both produce similar power.

Notice how I specifically mentioned Akrapovic. Don't confuse me for a brand whore.

The real issue is that the market for our cars is pretty crap aside from Supersprint, not that all other companies that aren't Supersprint are crap.

I know the stock headers are restrictive, but for 1k plus are they really worth it? I'm interested but not for a while.

so what you guys want me to buy those headers too? first it was the underbody brace now this???? hahaha JK JK for that price id be tempted to try it out. maybe when i return i can pay the shop a visit and ask them what they think or if they have a dyno evidence with 130i's on the N52.

Make sure it is a post facelife 130i when the car reverted to our worse headers.

Yes please!

[kobeballer96]

Well i called today and the underbody brace is on hold to someone else. How do people run a business like that. They Told me to call again on Thursday to see if he paid or not, and if he didn't i will get it lol. It was the last one they had and will no longer sell it because ultraracing said Schmiedmann was selling them too cheap!

[kobeballer96]

ultra racing's page. i wonder why no US vendors make these? pointless mod on our cars? i kind hope the other guy buys it so i dont feel bad if i really did just buy bling.

ON a side note... My Dinan camber plates were shipped =)

[andrey_gta]

Ultra accepts best offer on Ebay. I doubt they are crawling with demand...
Their brace seems to be 200 USD and maybe some shipping cost

For future reference:

Making 135i rear brake's handbrake work on 128i:
http://www.zpost.com/forums/showthread.php?t=751080

Step 1) Must make "Supporting ring brake shoe" as bmw call it from the 130i/135i/335i/e9x xi (34216771430) for into 128i hand brake area, probbaly by replacing our version(34216771429)
$10 a side for new 135i spec: http://www.ecstuning.com/BMW-E90-335..._3.0L/ES60467/

128i version: http://www.ecstuning.com/Search/34216771429/ES60466/


May require cutting or drilling new mount holes, but I doubt it the 135i part just looks to be a larger diameter with same mounting holes.
The Knuckle does have one part near #12 which causes problems to this plan
http://realoem.com/bmw/showparts.do?...30&hg=33&fg=30
That is where the brake shoe & brakeline shoe expander mounts with bolts.
That metal tounge on 128i is too small. ( RISK METHOD = Possibly needs material added on top to make 135i brake shoes work...)

Step 2) the z4 thread had the guy weld a pieace to the brake shoes to make it work. In the 135i brake shoes need only about 2 cm from 128i brake shoe are needed to add by weld.
http://audio.home.xs4all.nl/zooi/z4/...11schoenen.jpg

Optional step 3)One step extra to make it OEM spec:
Removing our 128i 34216792239/34216792240 back plates in favour of 135i's 34216792247/34216792248 back plates. Because I had to cut & bend the 128i back plate to make 135i rear rotor not rub:

looks great. I wonder if we can replicate.


Ebay had some n52 MAF holers. the rest can be PVC pipes and such.

From carbon fiber made by the same company that makes F1's carbon fiber to Home Depot PVC pipe from China.

I think given the narrow window for gains that there is with the airbox, and the level of apparent research in this product for just a few HP, I doubt an Ebay/Home Depot hodgepodge will yield any real gains.

We have designed the main airbox so we can use it on multiple applications by have a different MAF housing, brackets and cold air feeds. On the M5 which we have designed it on the OE cold air feeds are at the front of the car which makes this intake very effective.

Are you saying with adapters there could be an application for our cars?

Make a new thread! I had one for my E36 M3 and thought it sounded great. I would love to see a write-up with development photos and such. It is always great to have more products available to us.

Probably would have had better luck putting that in the 128i section. Also, if you want to stir up interest get us some pictures!

Awesome! The M5 intakes look like works of art

Maybe an n52 aplication would be possible, the engine doesnt really like intakes
