    bhp and afm reading

    horse power at the wheels


    my new custom map spec is as follows as of jan 2008

    apexi airfilter

    custom aluminium intake pipe
    apex type 1 front mount intercooler
    HKS ssqv dump valve to atmosphere

    apex turbo back 3 inch decat system.
    koyo race radiator
    greddy profec b boost controller
    and of course a H-dev custom map

    i am very happy with the results but i seam to have a slight boost issue

    im running 740 injectors with the smaller gt2871r .64 housing on a jez custom map

    the hks actuator is set to 16 psi

    boost was set to 1.6bar ish but tails of to 1.3bar and thats under investigation at the mo

    you can feel the engine has a flat spot at high rpm, and that shows in my graph.

    desired max pressure 1.6bar (23psi)

    profec b high boost settings.

    set 75%
    gain 5%
    set gain 19 psi
    warning 24 psi
    limiter 10%

    (i think i have the first three the correct way round lol).

    i havent had it on the RR again yet but i have adjusted the set gain to 21 psi now and it feels as though it is pulling better at top but i cant be sure what the engine is doing.

    any ideas would be appriceated as to why the boost is tailing off and how i could over come it.

    my new flywheel power figures


    my new boost and afm reading plus power at the wheels

    Here's the graphs

    A nice 300+ ft/lb of torque from 3,500 rpm to 6,000 rpm


    Power at the wheels, Christian said they should've just squeezed the last .5 out at least for the graph but didn't realise until later



    NEW GRAPH @ Interpro 27-05-07 (Car was strapped down hard which may account for the higher drag reading, very pleased though)
