    42 LB injectors

    Ok guy I am running 12.6-12.7 at WOT with the stock injectors and at 5-6000 I am around 14 what do you think should I install the injectors anyway or will it hurt performance or will I just be using more fuel

    also with my set up basicly a stage 2 should I be running different plugs

    Jarrett,

    when it was stock it would run 13.8- 13.9 at 5-6000 RPM but this is not a problem because there is not a load on the motor

    I basiclly have a stage 2 with the RR SC wheel

    Rodney (TNrxp) said when he did the injectors it swallowed gas. He has since removed his RR wheel and injectors so his ski would be more cruise friendly. If it was able to run without the injectors you might get the best of both worlds.

    Someone posted how airplanes used boosted engines for the higher elevations. I wonder if since the air is different at 500ft elevation that the RR SC will have a different A/F then if we were at 0ft elevation.

    Guess we will only know when everyone brings there ski down for the AWA show. Probably be cooler weather in a couple weeks though. Starting to see some high 80's.

    If your not full on the throttle the whole time with the 42# you probably won't see the tank drain too fast though right?

    no, unless you have a controller to customize the fuel curve it will use certain percent more fuel across the board - from idle to WOT.
