    New intercooler and rebuilt supercharger still only get 7680rpm and 65mph

    Hi I'm still at 7680rpm and 65mph with a new fizzle xs intercooler and a rebuilt supercharger, I'm at the point of saying that's what still seadoo is going to do at stock. Any other things that could be holding her back. Now the write up on this seadoo is only say she will do 66 mph. Now if it was flat water I could see mine getting there. But is the rpm still to low

    It's A 2008 rxp-x 255, frist she was give me 7625 rpm then down to 7560 to 7200 rpm. I did see 7700 and 65.5mph once. So I took it to the seadoo guy here and he said I need a intercooler and a supercharger rebuilt. So I did that and tonight she still only went to 7680 and 65.5. Now I did a jump and I seem 8120 in the air. But nothing like that in the water.

    Yup I agree, I have worked on my polairs for 4 years and this my frist seadoo. I will learn the 4 tec engines just like the 2. And you guy are a great help. Now I see online that this seadoo should only go 65 to 66 mph. I'm all most there. But I'm scard on the rpm But if its a intake gate or a pitch in the impeller great that's a easy fixs. Now the reason for the new intercooler and rebuilt supercharger is the seadoo guy said the oil seal in the supercharger wasn't put in right or moved wich pluged the intercooler with oil and water, wich was there I seen that. How much can the intercooler take I don't no. Also he said it was leaking. Now on till I get it tested. I don't no about that also

    Regardless of your speed, your down on rpm. You still have some further issues going on here. You need to figure out what prop is in that thing!
