    What's the most timing you have added at WOT with Vipec or Motec?

    Just trying to see how far people are going with respect to timing.

    We are using the 1000CC mapping from Riva and doing an overlay table adding 2.5 from 4k rpm to 8k, bringing it down to 2 from 8k to 9K.

    This is in an engine with Riva springs and ET18 wheel, we are planning on adding more timing on another setup with an ET15.5 but have not gotten to it.

    As I understand you want to save the MAPS with additional timing for short races/closed course.

    I don't have a Riva or Vipec but I can tell you I am running about 20 degrees at WOT and intend to keep that timing there even after upgrading to the B1 wheel.

    timing

    depends on what type of gas u run high octane (C-16)Race Gas the more timing u can run also what your static compression is

    I guess we have been conservative since we are running 21.5 at 120 KPA (17.5 psi) and 19.7 at 140kpa (20 psi) 8700 RPMS this is with 93 gas.

    We' have been running that timing for quiet a while with comps of course.
    I would love for Pete to chime in on this ...

    The 20 degrees I'm running is considered very safe for boost levels up to the E1 wheel from everything I have read from Pete and others.
