    255 engine

    i was thinking why not put a 255 engine in a 215 hull because the stage 3 package has the same hp rating

    the comparisons are as follows

    Hull

    Length- Rxp 307 cm Rxpx 307cm
    height- Rxp 118cm Rxpx 116cm
    width- Rxp 122cm Rxpx 122cm

    The engines are basically the same

    Engine

    displacement 1494cc
    bores x Stroke 100 x 63.4 mm
    compression ratio 8:4:1

    i cant remember the supercharger psi ratings of my head now but what do yo guys think

    Just add the X charger and an external IC to the 215

    Most notable difference is on the intake grate area...

    rxp

    i would think that the rxp hull would be faster ad not overstuff like the rxpx also i have seen two brandnew rxpx and rxtx with cracks in the intake area. this seems to be a big problem with the rxpx's

    but i remember reading somewhere in the forum where someone mentioned that the x hull was really made for holeshot because of some venturi design

    so what does this larger tunnel allow for, a decrease in top end and an increased holeshot

    Higher pump volume & higher pressure that can cause a dangerous overstuff problem causing an unexpected swim
