    Another RRFPR stage 3 setup question

    I also dont have a LM1 yet but want to get this setup for the weekend for impeller testing. I picked up a RRFPR off of the classifieds and was wondering what I should set it at until I can get a LM1. Heres my setup
    4" Kanaflex, Rude 1, 50# injecters, Riva ECU, Riva 2nd Gen IC, Jerrys waterbox, Rotax Racing thermostat, 68* water with about a 90*-95* air temp. What would be a safe setup until funds allow the LM1 and time to take the J pipe off to get the bung welded?

    many have had success with the setup you have and just the stock fuel system.

    Yep, stock reg should work or set the rrfpr to 58 without a boost line hooked up and you should be pretty close but of course its best to check A/f to be sure.
