    Rude Supercharger Results

    I recently installed my new Rude supercharger that I purchased from the online store and must say it has exceeded my expectations X2!!

    Since I am located in South Florida I stopped by to see Brian (bttek1) on the forum and purchased his fuel controller to go along with my Rotax Racing ECU. He already had his fuel map programmed for the Rude charger and all I had to do was to install it in the boat.

    My first run with the Rude/Rotax ECU and fuel controller got me INSANE acceleration along with a top speed of 81.8 MPH using a skat 15/19 with a 80mm nozzle. Max RPM's were 8500-8550!

    This setup absolutely blows away my previous Riva Stage 3 in both acceleration and top speed. With the Riva I was only able to manage a max speed of 78.9 MPH and that is with me trying every prop and nozzle combo that I had.

    The bottom line is that the Rude Super charger is a winner!! This along with the Rotax Racing ECU and fuel controller is a MUST for those wanting the ultimate accelerating/top speed boat!!

    Nice numbers, you beat me by .8mph but I am using a 81mm turning 8550 with 1mm added pitch. Just put in thermostat and riva intercooler pipes. Hopefully will get 82mph with 81mm ring.
    Are you using a stock 15/19r impeller? let me know... The Rude with the 81mm feel nasty...Love it!!

    81.8 MPH using a skat 15/19

    Is that prop bent or modded anyway or just OUT THE BOX?

    Hello Jerry.. Frank is a local customer that purchased one of the first Rude chargers. I referred him to the online store but I think he used his dad's credit card so this is why you probably do not recognize his first name.
