    The friend of mine who's already had it installed a few weeks ago unfortunately didn't go on a dyno before he had the intake installed. I didn't either because I'm still in the process of figuring out the ideal COBB map for my RB turbo powered car. I have done tons of logs though with the stock pipes, and will do more with the pipes installed which may give you an idea where improvements can be located. IMO the gains will be even higher for people with upgraded turbos, as it's in particular in that case that the engine needs more air.

    My garage called me yesterday and said that there are some complications - as the front tubing is larger than stock, my additional oil cooler from AR Design will have to come off, as the oil lines are in the way. As I still have an improved stock oil cooler with roughly double the capacity that should still be fine.

    Another problem was that apparently the end of the front tubing that goes into the turbo is just a little bit too short and does not slide 100% into the turbo connector (it's only on the first of 3 clicks apparently). I hope to receive some photos so that I know what it looks like, but my mechanic says that he believes this not to be a problem.

    And although this is OT - don't get me started on the clutch / flywheel. As you may have heard, I had a ClutchMasters FX300 with a new stock flywheel installed a few months back, and now it appears both the flywheel and the clutch are scorched / glazed over. As a consequence, not only do I need to install a new clutch (HPF Feramic stage 1) which I wanted to do anyway, but I also need a new flywheel. The strange thing is that the problems I experienced with the CM clutch were there from the start (strong juddering when going into first gear and reverse), which means that the damage to the flywheel / clutch was also there from the start (as I did a proper 1500km break in procedure myself). I have the suspicion that the guy who installed the CM clutch (who is different from the garage that is currently working on my car) stepped on it from the start (also because the RB turbos were installed at the same time) and damaged both parts. Quite annoying, and a couple hundred $$$ lost again.

    With regards to your comment about the clutch, i hope your HPF stage 1 turns out better than mine. What you described your FX300 doing is exactly how my HPF stage 1 drives. I dont think you can find a non chattering clutch that will hold the torque of a highly modified N54 without dealing with the chatter.

    I drove a HPF stage 2 a short while ago and it was much, much better than my clutch. So I do have hopes that this one will drive better. I don't mind a little chatter and agree with you that it is probably unavoidable. But from what my garage told me, the clutch and flywheel were both damaged by heat which seemed to have led to most of the problems I had. I hope to avoid that with a proper break-in of the new clutch and flywheel.

    But of course it's also possible that the torque with the RB turbos now is simply too much for the OEM flywheel to cope with. If that is the case, I may think about a single mass flywheel although this would of course chatter quite a bit in neutral.

    if you have been running a stock flywheel there is no reason for you or lulz_m3 to have chatter. the whole point of the dual mass is to stop the chatter. most people only hear the horror stories online, unless a person is doing a review of some kind. good luck with your HPF clutch alpina, i hope it works out well, HPF is a great company.

    lulz, if you're having problems/annoyances don't live with it. complain, try to get a refund if possible, and find another solution. it's not right that you have to coop with a $#@!ty clutch (maybe a bad install, bad individual part, who knows). there is a lot of competition and i'm not here to sell you something but if you'd like we can continue in PM or in the N54 clutch thread and discuss options for the N54 further as to not take this thread OT.

    It actually seems to be getting better, especially after some abuse at the track. Either way im stuck with it, and definately wont be paying labor twice for the install. I install everything myself, but a clutch is just too much of a hassle without a lift in my opinion.

    Looks really nice and high quality. Looking forward to your install, and I wonder if they'd fit on a 335is. Good luck with your other parts as well!

    Got the car back yesterday. The box looks great. Here are two photos:

    I can't give more detailed impressions because, as mentioned before, I also got a new clutch installed and have to break that in first before I go WOT and do some logs with the new airbox.

    The HPF clutch is quite a bit heavier in pedal feel than the ClutchMasters I had before. There's still quite a bit of judder when engaging the clutch, but I'll wait for it to break in before I give a final feedback.

    Looks really good. Does it do anything (good or bad) for the spool sound of the RB turbos? I quite like the sound of those with my open AFE filters.

    About the HPF clutch, mine seems to get a little better with the judder over time. It now has about 1.500 km on it, and if I give just a little more gas than I used to when starting there's no judder at all in 1st, still a little in reverse. And queing in start-n-stop traffic for extended periods is really no fun (never was, but much less now...) with the required pedal pressure.... Click here to enlarge

    Looks amazing, does the intake connect to both kidney grills? Also how close does the intake get to the Forge DV? Just curious cause I am wondering if they'll fit with the larger turbosmart BOV/DV

    The filter box connects to the stock intake snorkel that goes to the kidney grills, so yes it connects just like stock to both kidney grills.

    The box comes very close to the Forge DVs, but it's manageable.

    As I've mentioned in other threads, I have recently acquired a replica of the intake system that Alpina uses for their Alpina B3 S Biturbo, and which features aside from a carbon-look airbox - which is slightly larger than the stock 335i airbox and inside smoothened out with less edges - also the two inlet tubes that connect the airbox to the two turbos (the OEM part no. of the original 335i parts are 1371755654 and 13717556550). Alpina has widened these intake tubes as they are quite pancaked due to the restrained space in the engine bay, and have in particular made the inlet diameters larger. You can see it here:

    Attachment 19228

    Unfortunately the original Alpina parts are not available as Alpina does not sell them to anyone not owning a B3 S Biturbo. As a consequence, they have been replicated by a shop specialised on manufacturing fiber-glass reinforced plastics called Gfk-Technik Glück: http://glück-gfk-technik.de/airbox-135i.html. They have taken the Alpina intake system, made the inlets even a bit wider, applied carbon for the lid of the airbox and used aluminium machined connectors.

    This shop usually does not retail this product but rather sells it to tuning shops such as Tuningwerk or Manhart, who then sell it on (for a substantial margin). The German tuner Motorsport24 for example sells the airbox for 2500 EUR (see here: http://www.motorsport24.de/motorspor...box::2027.html), Manhart for 2800 EUR. The manufacturer himself sells it for around 1800 EUR, which gives you an idea of the margin that some tuners obtain for themselves.

    Due to requests of some of you, I've made a few photos of the airbox which will be installed in my car in the course of next week. You will also see on the photos that you need two hump hoses and four clamps to attach them, in order to connect the upgraded inlet tubes to the stock intake system. In addition, I've made a photo showing the stock airbox besides the new one.

    Here we go:

They have all the equipment and we're hoping to make a version of these pipes, although in some sort of metal (not plastic), and offer them to those interested. We're looking for other ideas and possibly also doing another catch can based on the knowledge gathered through my PCV research but we'll see. I'll post up some photos of the shop in another thread when I get a chance.

    Looking forward to seeing how those pipes feel to you on the car. Good luck!
    How are the parts making coming along? Do these inlet pipes yield a big improvement over stock pipes? I am assuming/hoping that it doesn't take too many hours to change the inlet pipes.

    I like the smoothed out airbox. I've been planning to do this for a long while with mine. It will reduce air turbulence inside the airbox.

    I also like the turbo plumbing. The smoother the plumbing the less restriction and therefore the easier the turbos will work. The turbo inlet pipes are the only components I'd consider purchasing. I can smooth my own airbox Click here to enlarge.

    I know that @rick@defiv was working on enlarged turbo inlet piping -- Here's the thread with some pics of how it turned out: http://bimmerboost.com/showthread.ph...Upgraded-Stock

    Doesn't do anything for the OEM airbox, but that's easily addressed with a BMS DCI or any other of the mainstream intakes

    Changing the rear inlet pipe is not trivial.

    If anyone is interested in this, there is a possible group buy for this product in a german car forum.

    http://www.e90-forum.de/sammelbestel...ml#post1000648

    Just use chrome to auto-translate! Its still a bit steep for about 1200 euros, but half its original price, and currently the only airbox with upgraded inlet pipes!
