    Any more R&D C5 results out there?

    Interested to see if there are any C5 results out there that have been keeping quiet.

    Does this wheel setup compare to a Rude charger? The boost numbers seem similar.

    I have decided to keep the Rxp. I raced a friend on his SHO all weekend, and had a blast (beating him). He is planning to mod his, so now I'm motivated to do a few little things to the ski.

    I'd like to keep the stock IC for now. I've messed with the aftermarket IC setups a few times, and just don't want to get that crazy right now. I was thinking of running a Rude charger or R&D C5 setup with a 15/20 4 blade and stock IC. I have a 4" front intake on the Ski.

    Would 42/50lb injectors be enough for this setup, or should I run a FPR?

    To run one of those big SC's with the restrictive OEM IC wouldn't be a great idea.. maybe even a bad idea.. If you don't want to get crazy, try a green wheel or Riva (gen 2). These two have been run with OEM IC's with no problems.

    I thought about that, but I though I saw that JD1 was selling an RXP with a Rude charger & stock IC last year. It was running the stock air intake and stock injectors if I remember correctly.

    I've had the Rotax high boost in the past with the stock IC---I liked it. Just looking for the most Speed with the stock IC for now. I'm sure I'll eventually upgrade to an XS.

    I thought about that as well. I actually had an x-charger I was going to put on my ski this year, but sold it b/c I was going another direction.

    How does yours run?

    I've also had the Riva S3 (w/ Xs IC)---last year.

    What are your Gps #'s? I'd like to keep the Front air intake for now. I was getting some water ingestion with the Rear air.

    Im pretty pleased with how mine runs out. I was getting 76 out of it trimmed dam near all the way down. I had no choice on that because I didnt have my RE's yet. Im going to try next weekend or maybe this week for better numbers now that I got my RE's on and can get my trim up. But overall im happy with the X.
