    I'd raised the question elsewhere Mike and the 7064 was suggested. Highly recommended by all.

    See where the weld is really close to the holes ?

    You need to grind that away a little, otherwise the nuts / washers won`t be able to sit flush against the flange and you`ll get issues with the gasket leaking as you can`t tighten them up properly, the weld will stop it pulling against the flange. :thumbup:


    Looking a rather high spec build, what`s the use, Drag ?? I`m guessing it won`t be for the track with that size Turbo lol

    Yes Nige, being built for fast straight line road use and drag.

    Do you understand what I was getting at about the weld ?

    I do, I've already noticed it'll be a problem. I'll make sure it's addressed.

    The new 7064 arrived today, here's some comparison pictures. It really isn't to much bigger, but is very chuffing heavy and is going to require bracing from underneath and the top...I've a couple of ideas.

    What do you mean it's not much bigger!! What was you expecting, look at the intake size compared to the smaller one and the size of the exhaust housing!

    Could also tap a thread in it and use a high grade stainless stud and a K nut. Depends on the clearance on the turbo side though.

    Looks like it will be a cracking build! :thumbup:

    Welding on that collector is tight!! [8D]

    That one in the picture, will be modified to take the t3 flange.

    Gotcha!

    Just looking at the holes in the flange. You are using M10 or M8 studs or bolts?

    Hello chaps, what's your views on performance cams. What's the best out there...schrick, Kent, piper, integrated engineering, cat cams. Would like an all out aggressive cam for big power.

    ??

    It is an open ended question, that could only be answered if you know :-
    What is your perception of a fast car and along with road use, how fast you plan to cover the 1/4mile and at what power to weight.
    Is the component combination you have bought already suitable to achieve the desired ET and trap speed?
    Is rpm of maximum power matched by target trap speed.

    As a result there is no 'best' brand of camshaft, but a camshaft profile that matches what you wish to achieve. This could even be standard

    For example, I can tune a stock ABF engine in a Golf MK2 to achieve 14.4secs @ 96 mph on factory CZM 02A gearing and ~ 975kg of weight. 60 ft was 2.4-2.7 secs
    Such a car is perfectly happy to drive everyday in heavy traffic as well as attack a track with some vigour!
    Similarly, a MK1 with even less weight @ 830kg, a 16v 020 with a 4.25 FDR and maybe a tad bit more power from an engine with less friction, would do the just under 14 secs @ 100 mph with a 2.2 60ft
    However if I was more focused to break into 12s with the same engine, gearing + more engine filling at higher rpms will have to be considered and a camshaft based on previous data could be used to achieve target. And I am being over simplistic deliberately.

    These tasks are not just based on best brand parts, you go buy, fit and that is it.
