• Updated photos showing CP-E (Custom Performance Engineering) N54 Twin Turbo upgrade kit progress - Yes, it's still coming

      Updates on this twin turbo upgrade for the N54 have not been posted in some time leading to some speculation that CP-E was no longer working on it. As a matter of fact, the last time anything was posted on it was in November of last year. That updated showed a mock-up of the manifolds and the turbos. Since then things have progressed to actually having the turbos and manifolds mounted on the motor with a mock up of the piping.


      So yes, this upgrade is still coming. The N54 turbo upgrade market continues to heat up and really the main thing it is missing with a single turbo option out (kind of, still being tweaked and no real info from the handful of customers who have it) is an option for upgraded larger twins. For now, the only twin upgrades have been to the stock turbos.

      There is no timeline of completion but it looks as if CP-E and Vargas Turbocharger Technology will have the main turbo upgrade options for larger twins on the N54. Expect debate on the forums to soon shift from which tune to get to which turbo upgrade to get. Let the single versus twin debate begin!

        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.

        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.

        Wow.... they sure looks nice... Tony, you need to drop a few x-mas stage III pics online for everyone to dream about.

        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.

        Well being that full-race charges 1,000+ for their 'engineered manifolds' I can take a quick stab at what it has to say about log style manis Click here to enlarge

        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

        BMW used it with their E63 M6 advertising when the 65 AMG's were outpowering BMW as a subtle shot.

        +100 and a decision really should be clear

        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.
