doesn't look like you have it seated all the way. my pipes on both sides cover the square edge of the inlet/outlet. once the pipes are flush with the edge, i placed the clip

I've tried to pull it over further on that side till the charge pipe opening has even overhang around the full circumference of the FMIC exit flange and it rocks back to that uneven position.

On the FMIC intake side the lip of the charge pipe has even overhang around the full circumference of the FMIC flange, and doesn't have nearly as much play, and won't rock back and forth.

The clip on the FMIC exit side is fully in the groove (both the front and rear sections of the clip). I'm wondering if the groove on that side was made too large, allowing for the play.

If the clip is locked, then it's installed correctly and seated all the way - that's the point of the clip... If you tug on it, and it's not coming loose / apart from the intercooler, then it's locked.. All things manufacturing have a tolerance (both the intercooler and and the boost pipe), might be on the outer tolerances, but that's what the O-ring is for, to seal.. If you have any further problems, or think you have a boost leak - then email me please. info@csfrace.com

Email sent. I'm seeing some symptoms of a boost leak.

I ordered a new o-ring from the dealer to try, but past that I'm not sure what else I'd try besides seeing if it's possible to reduce the groove's width with a shim to pull the clip/charge pipe further over.

Anyone else getting symptoms of boost leak?

OP how are you liking the CSF intercooler? Any updates?

i haven't had any issues, but then again i haven't really driven it. i did take it up to some local mountain roads and didn't experience any issues. seems pretty solid, but the real test will be when i can get some track time. I'm still sorting out an ignition problem though.

can't go on Friday. needs to be on a weekend

[FaRKle!]

Just wanted to post an update.

I tracked my car this weekend at Laguna Seca on Saturday and Sunday. Saturday I ran with my OEM 328d intercooler, and Sunday I ran with CSF's. My charge air temps were significantly lower on Sunday (beyond just the ambient air temp difference). Max I saw with the OEM intercooler was a bit above 140F, while with the CSF I never even reached 100F. The 328d boosts to 26-27PSI. I will post some logs and plots later.

One thing to note, is that the angle of the inlet/outlets on the CSF IC are different than that on the OEM one. Despite this, CSF has told me there's no issues with the popular charge pipes (ER, and others) in their testing and customer experiences. An M235i owner and I compared OEM IC inlet/outlet angles and ours were identical. Even though the angles differ, my logs show me hitting my boost targets, and the car doesn't feel like there's any loss in power, so it doesn't seem to be causing any boost leak issues.

Thanks for sharing, waiting for my CSF now.

Waiting for my CSF also--wish they would expedite getting them made!

Agree!

Just got my CSF FMIC and VF stage 2 tune, waiting on my Fabspeed Sport Cat and deciding on which charge pipe I want to go with and then I will be able to contribute my thoughts. Living in AZ the M2 is pretty hindered during the summer so I am hoping this will help resolve some of the heat soak issues I experienced last year.

Let me know if i can hep with the charge pipe

if you are looking for an upgrade on your charge pipes. don't look no further. Quality on these are perfect /// Charge pipe and Boost pipe aka cold and hot side.... FTP motorsport ftw!!!

Most of fellow suggested to do cold site is enough, so it mean I just consider the charge pipe?

[FaRKle!]

As promised here's a plot of my data showing the charge air temps between the OEM and CSF IC's at Laguna Seca.


Along with lower overall temps, note the difference during the sharp/short peaks starting at ~160sec with the OEM IC and every lap after. That peak was the front straight, and typically the highest temperature with the OEM IC. It was well tamed with the CSF IC.

The ambient air temp on Sunday (CSF) was about 15F cooler than Saturday (OEM). Below is a plot with that delta subtracted from the OEM CACT (I know it's not totally accurate to just do it that way, but it gives a bit better of an idea).

Thanks for sharing! Happy to see the narrower range of temps with CSF, too!

hi all

does there need to be any cutting out of the OEM front bar or any other piece to fit the CSF into the m2 or is it a plug-and-play feature. looking for any issues for installation i.e. requiring custom work or new charge pipes etc.

Cheers

It's a direct plug and play intercooler. The only issue currently is not even an issue in itself, but the OEM bolts which hold the intercooler do not fit properly. You'll need a couple washers to spread the load onto the CSF intercooler. CSF is fixing this / providing the proper hardware in the next batch of intercoolers.

Waiting to here on the group buy for the second round. I gave all my info. Hope I hear soon.
