    15/20r would be way too much prop for that setup unless you would add an x charger and 42# injectors then it would still need to be depitched to bring your rpms up. A 14/19 would be better for that setup

    It would sound cooler from the exhaust...hang on better from the grate...but you will need more power for sure to turn that 15/20r. might lose speed because your rpms will be way down from the prop being to much for your current set up. see my mods...air and water temp + humidity play a big roll as well...you need a bigger supercharger+++it kinda a progessive thing. ditch the power filter and dont do the prop yet.Go with the 4" fizzle intake and a catch can. a 14/19r will fit you better at this stage...but once you start changing parts the need for speed will start and probably never end. lots of good guys and info on this site. let the search function be your guide! Welcome to the hulk and have fun!

    Scrap the Riva power filter and go with a Kanaflex DIY or Fizzle setup
    you won't be able to turn that 15/20 without more power, go with a 14/19

    you would basically have a stage I setup and that would be about 72mph at 8,100

    +1 on the 4 inch kanaflex intake instead of the power filter

    I think the best beginning mods is X-charger, 42's, a 15/20 prop, Kanaflex intake setup. and either a Riva or R&D intake grate. That's the best bang for your buck.

    what would the top end speed and rpm be from that? thanks

    Acceleration will improve, and your top end should be around 75-76. Some see more/less.
