    Yeah, some guy was asking about my mods today in the store...he said the Riva Stage 3 kit was 295 hp but I know the true dyno figures are lower than that. Plus in this humid and hot air I'll get less boost.

    riva stage 3 with 14 psi boost @ 8500 RPM, exact 288 HP on the real dyno

    maybe 5 HP more with a open waterbox, as the dyno exhaust system is more restrictiv

    the orginal RIVA Stage 3 has about real 260 HP at 8500 RPM

    14 psi is not possible with the RIVA Stage 3 SC !!!!! the dyno test was made with a B-Kit SC / RIVA ECU / RIVA IC

    the orginal RIVA Stage 3 has about real 260 -265 HP at 8500 RPM

    That's very interesting, a 30hp mock-up. I'd be interested to know the true hp of the new 260hp RXT-X...
