    TFSI ladderframe with an aftermarket plate instead of the normal valvecover
    Be aware most alloy aftermarket valve covers/ plates are for TFSI and dont fit on the FSI...
    as the FSI ladderframe has different bolt Pattern on the 4 corners

    Great postings, thanks HPR. Is there a part number on the HPFP block off plate?

    Brooky, I know you expressed interest in this on FB from the 1/4mile?
    So an all out top end sort of motor?

    Think most of what you need to know is already posted in terms of head flow and so on.

    It is >>here<<

    Unless you need some specific cam, lifters and stuff, which is where you best PM HPR.

    ^^^ I shared already alot onhere, think more than you can find anywhere on the net, or did you see elsewhere detailed flow figures from an ex works FSI engine and much other info ?
    I have spend alot time and effort to research things,talked to companies and develloped parts as a CNC Ported Cylinderhead, an Inlet-manifold and valvetrain gear, this involved quite alot travelling abroad.
    Then bought quite some parts that didnt work out ... its learning the hard way....
    But please understand that I can`t share every detail.....online ....

    I wasn't having a go, just stating that the point of the forum is to share information.

    Nothing worse than coming across a thread on a subject that you are interested in only to find that a lot of the info ends up being pm'd between people and doesn't remain in the thread.

    I'm not sure what you're reasons are for not being able to share certain info online but if it can't be shared online surely it shouldn't end up being pm'd to people?

    I think the difference here are the different arena's we operate in. Certainly from my point of view, and Hugo's I would think, we operate in a competitive competition environment. Much of what we discuss is out there and readily available if you look hard enough, some isn't of course, but we share.

    Some of what we don't discuss isn't out there and may have cost us 1000's of or to learn/find out AND be the difference between winning/loosing either through performance or reliability.

    Unfortunately you need to keep some things to yourself or just share in in a very limited way to maintain an edge, unfortunately forums are not ideal for that.

    As Hugo says I think CGTI probably has the largest collection of competition VW information available. If Carling built VW competition info forums, this is probably how it would look :)

    If its any consolation, I will have more info on FSi based N/A race engines soon as I've one on the bench once I finish the current one that is on there ;)

    Hello HPR,

    I'm building me a FSI engine (with an old "Dx" block) for a rabbit 1 Hill climb car.
    Could you send me Pics of the chain tensioner of the camshafts. Is it a hydraulic one or is it a mechanical one ? (Bttc, S2000)

    Thank you !
