    Question questions for x charger on 2007 rxp

    question number one is how can i lower the consumption of gas with the x charger and the 42s alone. it is eating my gas alot faster than with the 32 and the regular 215 charger.

    question number two is what speeds do you guys usually get with EVERYTHING else stock on the ski except the x charger and the 42 injectors.

    thanks guys

    Ride at 1/2 throttle...

    Seriously, the way the injectors work, you HAVE to burn more fuel... the stock 38lb injectors burn 38lbs of fuel every hour at WOT... The 42s = 42lbs/hr X3...

    So, stock is 114lbs/hr, and 126 respectively...

    With the xcharger and 42s (plus all the free mods you should have done) you could be looking at anywhere from 70-72 I would guess.

    your making more horsepower, your gonna use more fuel. My ski does 73.3 in the summer heat turning 7900rpm. I'm sure I could get 74-75 if I filled the ride plate holes and getting the rpms back up.

    I had a 15/20 but a rock did that in. Now I'm running the stock prop with 81mm nozzle until I get it fixed.
