    2009 JCW Clubman with mostly stock drivetrain. Noisemaker deleted, muffler
    between turbo and IC deleted, WMW
    turbo blanket, BSH OCC and PCV plug
    already done.
    I’m thinking of upgrading to a Wagner (edit: Forge)
    performance IC. The Forge (edit: Warner performance) looks
    heavier than it needs to be, and I’m
    not thrilled with how the Helix one is
    just held on by the hoses.
    On the flip side, this is my daily driver
    and I rarely drive it hard for very long
    at a time and I don’t track it, so would
    I just be doing this for bragging rights
    and ego gratification, or will I notice
    a difference that I will appreciate?

    My R58 has the Helix stepped-core. I thank it makes a difference but it has been on the car sense I bought it from Mark. I would say do it, especially if you live in a hotter climate. I put a de-cat down pipe on the car and that made a big difference! I can’t believe how much more torque it has. I put a spark plug extender on the post cat O2 sensor so I wouldn’t get a check engine light. Detroit Tuned sales a 90 deg one that works well also. On my Lotus I put an inline resistor to keep the light off. I will probably do the same on the R58.

    Correction: I thought the Forge IC was
    significantly heavier than the Wagner
    performance, but actually it appears to
    be lighter, so would be thinking of the
    Forge one.

    I ordered the Helix intercooler today.

    I’ve thought of a higher flow catted downpipe
    but all of them say they may still throw a
    CEL code, which would pose a
    problem with PA emissions testing,
    which is done through the OBD port
    and a visual inspection.
    A catless downpipe would be more
    problematic, as well as unenvironmental.

    Helix is out of stock on their 2nd gen
    intercoolers for a while (even though the
    site said 14 in stock), so ordered a Forge
    one from Way.

    You could get a high flow cat and then put the inline resistor on it so it does not through a code. I am surprised the high flow through a code, thats too bad. I wonder why they put the cat on the down pipe. It seems to me if they had moved it down more the turbo could spool better.

    Another change of plan.
    Shortage of Forge ICs that have
    the fittings in just the right spot, so
    now going with the Wagner Competition
    IC, which Way says fit great, are in stock, and are ready to ship at about the same
    price as Helix or Forge.

    Glad you found something in stock. Everything is in short supply

    You went full circle but all three choices were good ones so you come out a winner.

    Actually, full circle and a half, since I’m
    now going for the Wagner Competition
    instead of the Performance model
    (due to availability and “go for it”
    factors).
    Agree that all 4 look like winners.

    IC arrived today.
    Looks great!
    Nice black finish.
    Weighs only 10.4#.
    Will wait until after annual inspection
    early next week to install it.
    (Would hate to throw a code and
    have to get the readiness monitors
    set on short notice).

    While on this subject, the EVAP
    system is usually the last one to
    ready itself, but I found that my
    LAUNCH x431 PROS scan tool can
    run a leak test at will, and if it
    passes, the EVAP monitor changes
    to ready. I think the tank still has to
    be between 1/4 and 3/4 for it to run.
