    Best twinscroll turbo?

    Looking for advice on the best twinscroll turbo suited for a nicely responsive 400-450 bhp

    You know the answer to that already Matt.

    Owen Developments 71mm compressor twin scroll version.

    A very unstressed 450BHP and as much torque mid range as you dare to push your stock internals, assuming you are keeping it stock.

    Hello,

    With the famous Chevron's turbo.
    This is mapped safely, only with 98 RON Fuel and AVCS pulley problems (I changed it).
    Mapped with 1.4bar max. She spent 4 hours on the dyno on hot day, so we were not able to hit the 8500rpm and had spark issues.

    Next step will be E85 and little more agressive MAP (1.6 bar or more) and change exhaust, mine seems to much restrictive.
