My new toy. NZ new 60k last build month with N54. Most options ticked.

I lowered it with H&R susp. trialing 4 X E46 M3 front wheels.

Will play with Alpina reflash etc.

We did the Alpina reflash in house and walnut shell blasting with Ross@ BM Workshop. Huge difference and a must for all N54 & N55 owners.

Before and after pics of the walnut clean:

Are these direct injection hence such dirty inlet ports?

Yep.

It's a way of life with di engines.

It was one of the issues that put me off an RS4 wagon.

Installed JB4 last week and promptly destroyed the OEM charge pipe. Factory plastics don`t like the extra boost. Replacement with a BMS N54 Chargepipe seems to have done the trick.

Dechromed as a sideline.

Took her for a blast on a new road at the back of Hatfields beach over the Northern Gateway. Everything behaved as it should.

Where did the charge pipe 'malfunction' by interest? After installing my JB4 I replaced the charge pipe at the same time as it is only a matter of time...

Which map are you running on JB? I was running map 5 for a good month but recently ruined 2 coil packs so back on map 1 for time being, power delivery feels a lot more responsive and smoother (although boost has dropped from 15psi to 13psi) than I ever achieved on map 5

Running Map 1 at the moment: 13psi over the stock 8psi. The charge pipe broke away at the throttlebody end - weak point where the clip holds it.

Oh yes I see! Also looks like the middle bracket broke off as well or did that happen when you removed it?

Map 1 is a good bump over stock - I haven't tried map 2 yet as heard it can get a bit rough on the turbos without upgraded downpipes

Need to be aware map 5 is constantly "learning" -

I also run the backend flash map in conjunction with the JB4 and don't have any issues....

"Map 5 is designed to be continually adapting particularly focusing on the last three minutes or so of wide open throttle activity. Upon selecting map 5 it will default to "93 octane" levels (approx 14psi peak) and adapt up or down from there. Those running E30 mixtures will see the tuning become more aggressive (higher boost, higher timing, leaner AFR) during subsequent wide open throttle pulls while those running lower octane mixtures such as 91 octane will see the tuning become less aggressive (less boost, less timing, richer AFR) during subsequent wide open throttle pulls. It's important to note the map learning is always active. So should things take a turn for the worse during a run (intercooler outlet temps rising, oil temps rising, increased engine knock, etc) the tuning will respond accordingly"

JB4 MAPS:

Map 0: Stock bypass.

Map 1: 13psi. Suggested for most racing applications.

Map 2: 14.5psi. Suggested for those with exhaust and 93 RM2 or higher octane.

Map 3: Progressive meth mapping with flow sensor failsafe. See guide to enable. Meth use isn't supported/suggested without a flow sensor and map 3.

Map 4: Stock map w/ CAN active. Allows full logging and in dash gauges on the stock mapping.

Map 5: Autotuning map. Boost ranges between 12-17psi based on your cars octane, conditions, and modifications. Fully E85 compatible. If using E85 we suggest around 30% to start. Refer to the E85 FAQ for addl info. Resets to 93 octane level adaptions when selected and adjusts itself up or down from there.

Map 6: User defined map generally only used for diagnostics or troubleshooting.

Map 7: Race gas map. 18.5psi peak boost on the G5 ISO. Requires straight 100-104+ RM2 octane unleaded racing fuel. The expensive stuff. We do not suggest using leaded racing fuel. To use this map with E85 requires the BMS E85 back end flash, inline booster fuel pump, and a 40%+ E85 mix, per E85 FAQ.

Brendon and I were testing out WOT with a a small incline when it first happened (pipe popped off). We pulled over, re-connected the pipe and reset faults and reset data logging. Alas the pipe popped off again on map one. Got it back to the workshop and checked the retaining spring clip which is just made of mild steel that has been anealed, bent it to put some strength back into the clip clamp pressure and re-installed.

Went for another hoon, this time hit full boost with no worries then tried again. Heard the big pop, this time it broken the plastic collar around the pipe. Basically the charge pipe design isn't meant for anything over stock boost. The design has no tolerance for extra pressure and I suspect the collar was circuming to expansion of the main pipe, hence the breakages being reported. I suspect a lot of it is to so with the weak retaining clip as well.

Haven't had a chance to drive and log on the new charge pipe yet, but will do shortly.

First time I road tested my chargepipe install I hadn't secured the intercooler end tight enough and heard the big pop when I built boost - luckily nothing was broken so just tightened it a lot more and has been fine ever since!

So from the pics I can see BMS dual intakes, JB4, and chargepipe - exactly the same set up as me! (I do have the BMS Oil catch can installed too). Any other mods in the pipeline?

Would be great to meet up and see what impact the weight has with 135 vs 335 on some pulls :ph34r:

Retro fitted E9x M3 Strut brace & Micro-filter housing. Coupled with M3 swaybars should improve handling a bit.

First pic compares the 2 filter housing/trims.

i cant help but think there needs to a better design for those air filters, instead of leaving them stuck in the middle of a hot engine bay with only that OEM duct blowing in their general direction.

Latest mods: E9x M3 rear sway bay, floating rotors new pads and a set of F30 Style 400M wheels.

M3 Diff,1/2 shafts and swaybar takes out most of the stock twitchiness.
