    like it s been said above it was written when the oem 16v came out
    so it was nt as cheap

    and he mainly didn t like the oem head because of the vertical exhaust valves
    and the 90 bend exhaust port
    which is true is a dark side
    and yes he did try to promote the drake head
    but looking at the graff head seems like this one is really really good would love to see one in the flesh

    after many years of R&D now we can get as much power of an OEM head

    what about if we modify as much the drake , graf or oettinger head???
    with nowadays technologies and fuel

    but they are so rare not much people is willing to play with it

    by the way the oettinger head on 1.6 race preped is good for over 200 bhp
    with standard valves size 30 inlet and 27 exhaust and a big 8mml stem
    not bad

    on the big bhp head OEM 16V you already have bigger valves then that (as standard) and sometimes need bigger no???

    This is the 16v 'Austrian' head brought in by Autocavan in the 1970's. Valve covers were plain , no markings.

    That's what I'm thinking, but I'm not completely familiar with these.

    There is also a head cover in the top left of the middle photo :thumbup:

    Neal, this piece of info is what I've been looking for since the start of the John Button thread.

    From the same thread:
    My reading of that is John Button had one, 240 brake, and the other went to Levics.

    Absolutely brilliant to finally tie that up after over four and a half years. There is nothing this forum cannot answer :clap: [​IMG]

    Hi Mk1, haven't heard from Tony B for about 25 years ,but I think he's still in the Frome area.
    Didn't someone on the thread (had a Mallock?) keep in touch with him. It would be interesting to hear his slant on many things!!

    You called?

    What would you like me to substantiate 25 years after I wrote it? Sounds like my comments about the OE head being crap. Who knows...it's been too long to remember what I wrote (without re-reading it).

    I think the point was that in 1985, the state of the art technology was as follows:
    2010cc VW 16v racing engine was 210 DIN HP.
    1935cc Drake 16v racing engine was 295 SAE HP.

    DIN HP will typically be a few HP higher than SAE -- but that really depends on the weather conditions being corrected. It sounds like today's state-of-the-art is 250 HP on the VW 16v racing engine -- 25 years later. I think there's very good reason to believe that the Drake 16v wouldn't benefit also from similar advances in technology (and tuning) if it were done today.

    EDIT: Corrected Drake VW 16v engine displacement. I incorrectly stated it was 295HP @ 1995cc; it was 295HP @ 1925cc.

    Thanks Chris for the welcome.

    I know the articles I wrote 25 years ago have been posted in many places on the forums and other private web sites on the internet. I've re-read bits and pieces of what I wrote, and for the most part, I think the articles have held up pretty well over time. I took a lot of pride working at Drake, and that probably came through in some of the articles. It's pretty hard to know exactly how the landscape has changed in the past 25 years, when I'm not a part of it. Certainly there have been changes in technology and advances made along the way by everybody.

    Speaking of the Drake 16v heads...

    Stewart Van Dyne was the chief motor builder at Drake, and he bought the rights to the Drake 16v head (among other things such as the Drake "Offy") when John Drake retired. Stewart is currently building my BMW M3 motor for my attempt at a 200MPH run at the Texas Mile. I spoke to him the other day about the Drake VW 16v, and he informed me that he has 5 or 6 of them available, and one complete motor (with unknown compression ratio). He's willing to sell the 5 or 6 he has on hand, and remanufacture the Drake VW 16v head if demand warrants. The intake manifolds are available for carburated or mechanical fuel injection. The best approach is to take the carb manifold, and attach ITB's, EFI, and a modern ECU for tuning. If anybody has an questions about the Drake VW 16v, I'll be happy to answer the questions. Anybody who wants to seriously inquire about the purchase of one (be prepared for at least $5k), please contact Stewart Van Dyne @ (714) 847-4417.
