    Functional and optimal are two different things.

    That is true but saying it like that makes it sound like one has ultimate superiority that matters a lot in the real world and that is what really confuses people out there. Really, the place it'll matter THE most is in the price in the end

    One design does have ultimate superiority the question comes down to the cost and complexity. If a log can do what you need at a lower price point it is more practical. It isn't better though.

    Never said its "better", I said in a lot of cases it is JUST as functional and performant while at the same time ALWAYS being simpler and cheaper.

    I know, I'm saying one is a better design but the other may be more practical.

    Some people may be lumping cast manifolds and "log" manifolds together, indiscriminately. A log uses a common plenum (whether cast or tube construction), which is not as conducive to flow as a manifold that has fully independent runners and a collector (which could also be either cast or tube construction). Looking at these photos of the cp-e setup, I personally wouldn't consider their manifolds a "log" style.

    +1.
    When I post pics you will see we did not go log style, but not full tube either. We were able to keep all 3 runners very close to equal length, while also keeping them very short so it offers the space savings of a log style, and benefits of a tubular.

    Promised some last week. Actually made the post and deleted it before I posted because I wasn't happy with the design as it wasn't finished. I had the fabricator rework them, and it required ordering more Weld Els so we got pushed a week. I should have pics up very soon.

    looks nice but maybe to much for me with that type of power comes new expenses CHASIS, SUSPENSION, DRIVETRAIN BRAKES AND AERO. Power is nothing without control

    Yup Click here to enlarge And full-race is supposed to offer a kit for our platform sometime next year. So it'll be interesting to compare the two. Those posted articles clearly show solid gains. However, it may not be justifiable at its higher cost.

    What do you mean by you "did not go full tube either"? In which respect you don't consider your design being "full tube"?

    If you take a look at our protype manifold, you will see its not quite a log style yet not the coil of snakes equal length style you see. Take a look at CP-E's manifold offering from last year and you can see exactly what I'm talking about.
