I had most of it apart while installing the BMS OCC & changing plugs, so it didn't take much longer. Maybe 30mins? I had Mattyv's help with the CP & DVs and he'd fitted his not too long ago.

I might have a crack at it myself... being the long weekend. Ian your thoughts on DCI? Giac seems to think it is a good thing? I am pretty sure their mapping go over 15psi with their stage 2.

[micha3l]

I've tried both, and honestly stock airbox is fine, Ive run 18psi with the stock airbox.

DCI will be fine with the cold weather at the moment, but come summer time you will notice a drop in performance IMO

[Ian///M]

DCI are waste of time IMO... Stock filter is fine and paper filters protect engine. Cotton filters fine for track, but few HP increase not worth dirt in engine.

Thanks guys!

Nice thread and feedback mate.... FMIC & CP are next for me. Once i have the hardware setup, a Cobb. Unfortunately my bike needs new headers and some $, so 1M has to wait until summer for her goodies.

Just want to have an update on the Forge. I emailed them and they have been very helpful and big thumbs up. On the other hand, I asked for some information on tunersports and they didn't bother with the reply.

Heard good things re Forge support & products on other posts. So are you running stock DV's on the CP at the moment? I am interested to know the effects of both CP & DV independently?

Yes, I am running stock DV at the moment. Since I put the fmic and cp at the same time I am not sure which affects what. I have also changed the oil at the same time so it is difficult to separate everything. I would like to install one thing at a time, but that increases the cost involve.

I felt more power, especially in the earlier rev range and especially in second gear. I also found better response. The response would probably due to both as the Wagner and the ER CP would have less pressure drop. I doubted I would be able to report much difference with the DV, but I am start to log some data so to see how the pressure is holding after the DV change.

Upgraded CP or DV/BOV does nothing for performance. It's a preventative mod to stop either the CP blowing off at the throttle body or the DV popping off. These are the flaws of the stock setup. I personally have only had an issue with one specific DV popping off at 14.5psi. Most people don't upgrade these parts unless they experience one of these symptoms or they install it before other power mods as a precautionary measure.

[BBK]

Indeed Vinney, CP's are only really needed for higher boost applications and provide no performance boost at all.

[BMW86]

BMW actually revised the charge pipe design from May 09+ 135i builds to a 1 piece design as it incorporates the elbow section. The problems I mentioned can still be experienced though. That being said, I only recommend changing the CP if you experience these problems already or plan to run big power in the future. Or you could always get some electrical tape and tie down the DV's

[Ian///M]

Wonder if the part #'s for 135i(N54) & 1M are the same then?

It's the same.

Tbh, for most daily cars, it's probably not necessary unless you are already experiencing boost leak.

Imo, reasons for upgrading in order of priority:

1. You'll be visiting the track or enjoying spirited driving and want peace of mind that your charge pipe won't blow off - potentially leaving you stranded or damaging something in the engine bay,
2. To eliminate boost leak,
3. You want to run meth, and/or
4. You personally like the sound of a blow off valve

Just want to requote this. Although, practically there probably isn't much difference.

I personally have the CP because 1M was known to blow off its CP, and whilst I am at it, decided to have the Froge DV as well for increase boost for later mods.

I love presenting complete data - so theoretically the CP may increase response due to the above reasons, but practically it might not be significant.

Vinney, have you got any delta on your IATs? Silly me haven't logged them before I changed it over.

A while ago I ran another 135i side by side to whilst we both ran some logs and my IAT's were significantly lower, the only difference being my FMIC too. It definitely works.

When are the IAT's too high? ... over 45 deg?

I don't think it's a case of IAT's being too high, but more so about keeping it as cool as possible to minimise heatsoak and improve consistency for back to back runs.

[BBK]

Was that with me Vinney? If so, I remember yours being at least 20degrees cooler...

Yes, that was you Rich. It was a while ago, don't really recall the conditions etc but the difference was quite noticeable.

With the P3 gauge it is interesting to see how long IAT's take to drop on repeated pulls.

On the track with cool flowing winter air, IAT's do stay low.

FMIC is definitely on my list, probably the ETS 5" in summer.

Just want to say thanks to Florian at a-workx for all the help and information on my selection on the brakes. Good to see a company concentrates on weight savings rather than power with their mods. Looking forward for them to come in .
