    Did you measure your speed with a GPS or was that from the odometer?
    More importantly, what were you peak RPM's?

    Your RXP should GPS 66-68 mph if everything mechanical is in good shape.

    You should be mid to high 60's on GPS at around 8100 RPM. The speedometer usually reads a little higher than actual speed. If that is your actual speed you need to take a look at your pump and prop and see what condition it is in. I would also be concerned about the condition of the supercharger and get a rebuild done as soon as possible if it's the original one and hasn't been rebuilt yet. You don't want to wait on the supercharger. If it goes, you could be looking at some really expensive repairs.

    Rpms will point you in a direction. I was chasing a huge rpm loss with my RXP. Once i fixed the rpm loss obviously mph came up.

    What was the cause? Mine won't go higher than 7900rpm but indicates 70mph always.

    7900 is good depending on air and water temp. You can lose 150-200 rpm just on ambient temp, also if your intercooler is heat soaked.
