    rxt top stock speeds??

    I was under the impession that the SC rxt's were pretty much ALL close to 70 mph, at least on speedo...I was looking at a 2010 215 hp the owner says he had it up to 63?? sounds pretty disappointing to me...I know there are mods that can be made but to start this low? my 04 sc gtx touches 60, thought the '10 would do almost 70 stock???....Also considering an '09 rxt...guessing this should be about the same?
    ETA- after a little more searching it looks like this is pretty close to correct, bummer...I was thinking it should be more as my 05 rxt touched 70, again, at least on dreamometer

    average 215 RXT's run 63-65mph. The 215 RXP's run 67-69 in stock form.

    thanks guys...a little disappointed...thought my stock 05 was around 70?(at least on speedo!) don't want to go slower with a newer one....I was recently on an rxt-x and rxp-x they were both 255's and about 70....guess that's what I'm needing!

    T-X 255 is a wonderful platform for speed as is the P-X

    OK, I know I can do a lot of research and I'll try... but if someone knows a close guess off the top of their head I'd appreciate it as time may be a little important here....I can maybe get a good deal on a very low hour '10 rxt....anyone want to throw out a ballpark cost to get a solid 70 mph?
    I'm thinking, wheel, injectors, maybe flash and/or external IC...2k do it? thanks!

    no, a drop in wheel and 42 lb. injectors will not add 3-4 mph to a stock RXT. Wheel or x charger, external intercooler, 42s and solas 15/21 solas impeller will get the job done with room to spare. A good stocker will run 66-67 with good conditions here in Michigan with a correctly pitched stock impeller at 700 feet elevation with an 80 degree sunny day.

    hmmmm X-SC 42s and ebay intercooler I was seeing 70 all day long(free mods included). ET 127 pushes more boost across the board with less maintenance. It depends on fresh/salt temperatures, humidity etc...
