I too have just put one of these in my Hyper, had a problem with the carbon clutch and standard springs but I put a Fastrax alloy ( Blue ) clutch in it with the 1.1mm springs, RB pipe/manifold and this thing rocks, i thought my Hyper 8 port was quick but this thing just lights my pro vegas on the spot, love it.

Just got to find some more better suited tyres lol.
