Fuel pressure regulator

  1. #1
    Hi Guys

    so ive seen a few threads and remember from looking into it before that the vtr FPR is 3.5 bar and the vts is 3.

    while i understand higher pressure is better for acceleration but not so great at constant speeds, would half a bar make enough of a difference to make things start going wrong? i.e, will a standard engine run ok on a 3.5 fpr or will it choke drown and die? will the ecu deal with it or would it need remapping?

    i did intend to turbo the vts if and when funds allow, i imagine the pressure would have to be matched to the injectors, so would i be better off running a 3.5, or would it be easier to set up with new injectors etc etc with the standard 3 bar?

    thanks
