    Maybe we should contact http://www.chrfab.com/ I had a set of cams from them in a northstar, 4 cams, under $600 shipped, with springs/retainers my motor revved to 8,000rpm and made a delta of 150whp (320whp before to 470 after).

    No reason for cams, even on rare DOHC platforms, to be expensive. Just saying.

    They just wrapped up their M157 turbo kit that is now officially for sale. Let me guess, that's vaporware too?

    I would like to think so but for modern BMW's I wonder why it always seems to be Schrick and only Schrick...

    i assume because they're the only one who stepped in when the market was small, and it's still (relatively) small

    not like nissan/toyota/honda/domestics where every second owner (not literally...) has a new set of cams for performance so you have 5-10 people who have off the shelf setups and all of them will make a good amount of profit from it.. same question as to why there's only a small handfull aftermarket turbo/sc options shop wise for M-motors compared to an evo/chev/supra/silvia/skyline where every country has 10 or 20 almost haha.. (how many are there for the S65).. not like IC's or exhausts where everyone wants one

    renntech seems to think it's possible to make a set of cams, and i can't see why it wouldn't work out well?

    Yes but I'm more saying we have 1 dedicated BMW cam specialist. There must be something to it.

    well we'll find out soon enough if renntech have too much trouble getting them to perform well, if not.. hurray! it doesn't look like schrick plans on making any N54 cams any time soon? (has anyone contacted them about it at all?)

    i love how every time cams comes up (once a month or so) we have exactly the same discussion Click here to enlarge

    sticky: there has to be a reason why only schrick makes vanos cams
    me: i cant see why, i wonder why?
    sticky: eeeeehhhhhhhhhhh
    me: eeeeeeeehhhhhhhh

    haaha

    Agreed, I mean I don't expect that cheap of cams. All I'm saying is there is simply no good reason for tons of $$$ I can think of, other than R&D, but really now these aren't exotics. And computer sims have come a very long ways. Maybe there is no perceived market, maybe there is no market, maybe R&D scares people. But if you look at Rob Beck, Terry Burger, and Tony Vargas... it's kinda obvious that the platform isn't impossible if you have some motivation, and is profitable if you price reasonably.

    Premium pricing products will never make as much as the mainstream alternative over time. If you can monopolize the mainstream, fewer companies will see the value of competing, and then you take the market. It's just business.

    I know but I'm speaking strictly about the cams. I remember a tune telling me a while back only Schrick has the resources to get things done correctly with modern BMW cams.

    Who knows, but I figure we should see many more cam upgrade options out there yet we don't.

    I'd love to know a reason why, I mean if it's DME related fine, proefi needs a fire lit in that case. But I think it's more just companies are too busy with their own niches already and this society is so risk averse these days. JMO.

    My thought is any cam should not be a huge deal for most top name cam makers. They have the programs, the skill set and they understand every little subtlety on what happens with cams whether it be VANOS/VVT, VTEC, DOHC or OHV cams. Most cam companies tend to start off on the reserved side and offer something with only slightly more lift and duration and go from there.

    Its been almost 2 months with no update at all. I wouldn't really call that impatient.
    I don't keep up much with MB stuff, sorry.

    I just would really like to see some cams come out. I really liked the Schricks I had in my M3, made a world of difference for that car.

    http://www.co-ordsport.co.uk/attachm...Price_List.pdf

    i emailed schrick and got a pretty quick reply... their cams seems to have a LOWER duration than OEM N54 cams though? (245/261 by the tech sheet i found) - not sure on the other values :/ (lists .3mm more lift :/ )

    0476A1521-00 252/119-?/10,65mm/0,0,32-?mm exhaust
    0476E1501-00 234@1,0mm/117,2-?/10,0mm/0,55-?mm intake

    site above lists 2 exhaust and 2 intake cams?

    are they just OEM replacements or what?.. or a typo from M54 or something? quite confused.

    There's only 1 exhaust and 1 intake cam on the N54. That is from some V8..

    i know there's only one of each being a straight 6...
    but.. so...
    darn a typo then Click here to enlarge. damn schrick lol.

    ED: though it lists 2 exhaust and intake as totally different part numbers.. and even if it WAS a v8.. it's not like you have two exhaust cams of different spec, they have to be identical or the motor would run like 10 kinds of ass?

    and it has separate extensive listings for S65 and other BMW V8's.. and it DOES specifically say 6cyl 4v?

    i sent them another inquiry to be sure lol

    In a v dohc motor, the intake and exhaust cams for one bank can be different lengths than the other bank because the cylinders in one bank are offset rearward from the other bank. This is likely why they need four unique part numbers for a dohc v8

    Well, Dimitri it's a matter of concentrating in things that can pay bills & sustain R&D. The whole PAW N54 camshaft project got on hold not because it didn't make power. We had some other concerns & how much it time it requires for proper install + need NEW camshaft ledges to be used (As you don't want an infamous camshaft ledges wear if you don't install it right). Also, costly production using hollow hydro-forming vs. less costly hollow billet production + type of cam bearing seals (carbon or steel) to be used. And, also more profiles of intake vs. exhaust lobes to be R&D. That's right, the camshaft lobes for intake vs. exhaust ARE different in lobes sizes & not just in paper (If anyone have free time... take a look at a stock intake & exhaust camshaft and you will see what I mean)

    In the end, a final production complex camshafts you have to figure out how much time & support a company need to sell to break even. So, for now I prefer to keep this camshaft as a private use for now until cost comes down. BTW, it's not a BMW tax price like how some would think, it's the amount of trials & test it requires during a period of at least 1year test that this will need to be validated. Just like the RENNtech AMG63 biturbo upgrade, we've tried 3 versions of turbos for a period of 1 year to get into a conclusive logical option.

    Will give you all an update.

    Those kindalook like E36 M3 US S50/S52 cams. The 252* cam matches, but I cannot find a BMW application 234* cam.

    After looking at VAC & Turners website, it doesn't appear Schrick sells N54 cams, let alone any other E9x 3-series cams except for the S65.

    ahh fair enough, yeah that parts list does list 4 cams for the '63 and '65.... but it lists it as L0 L1 R0 R1.. where the 'n54' list just has -00 -00 -00 -01 and mismatching part numbers... i'm sure i'll get a response today clarifying what they've done lol.

    if you search (google) for the part numbers it shows up about 10 european vendors selling them as a brand new part it seems?

    the specs are the most confusing part to me because the values look all wrong, shorter durations, very slightly higher lift, unsure other values lol, i'm hedging my bets on a 'typo'?.

    so it's possibly even 12mo+ off?

    aw Click here to enlarge. better late than never i suppose Click here to enlarge. was hoping they'd be ready in time for my rebuild which is getting closer lol.

    ED: just curious, hollow hydroform vs hollow billet... i'm guessing you'll go with the billet? haha

    Renntech is originally a Mercedes tuner and has been doing a ton of work in that market. A quick trip to BenzBoost.com would show that. They simply are working on different things right now.
