    jims open loop plate results 2012 RXPX260

    jim asked if I would post my recent open loop plate results. first off for starters the ski has a torx stage 2 cam. riva gen 3 ic. 15/20 srz. riva open loop and motec m130. I am using the bone stock air intake and exhaust, stock charger, stock grate. my max speed before the plate was 75 mph on the motec log. the dash read 76. after only installing the jims open loop plate max speed on a 10 second wot pass just passed 77 on the motec log. the dash read 79. I think I can squeeze one more mph out of it I just ran out of smooth water today. the ski handles better than I expected, if anything the handling improved at all trim positions. with the stock plate the ski would bounce at full trim over 70. with this plate the ski doesn't hop at all at full speed and trim. also I can feel the ski has come up and out of the water when it is trimmed but it never feels too loose. I was extremely impressed with how well the ski handled with this plate. I though I would lose some hookup in the chop but its actually the opposite. all around this is a great bang for your buck mod. I will update speeds when I get out in the smooth water in the morning. not many that I know of have tried this mod and ones who have tried it are staying silent about it. as far as the pump stuffing concerns with these new hulls. I will be installing a tunnel sensor to see what kind of pressure I am running and then see if I need reliefs in this hull. cant complain!

    Also for what its worth. I decided to back timing off. On the 75 mph run I was at 38 and I ran at 36 degrees with this plate. I had decided to back it off just to be on the safe side as I was getting close to my limit with the fuel I am running. So if I put it back to 38 and get some glass water I wouldn't be one bit surprised if it is more than a 3 mph gain from the stock plate

    Am amazed at your findings. Amazed that it didnt bounce and that you liked the way it made the ski handle, I personally hated the Riva plate on my 06rxp and vowed that I would not go that route again. Might have to reconsider.

    Evan,
    Does he make one for closed loop as I don't want to go open loop.
