    4tec SCIC dyno figures

    Stock...209 HP @ 8100 RPM

    Riva Stage 1...211 HP @ 8100 RPM

    Riva Stage 2...229 HP @ 8100 RPM

    Riva Stage 3...295 HP @ 8500 RPM


    So I would venture a guess that you're a little over 250 HP.

    Riva's dyno figures for their stage 3

    ...you are lacking ECU and 50# injectors for sure, air intake and exhaust add a few hp,....at 8100 they are about 270 h.p. .....but I think their ECU and larger injectors contribute a good deal more hp even at 8100 rpm....I would venture to say that a setup like yours (and mine with Rear Air Kit and thru hull exhaust) would produce between 250 and 260 hp....but this is some 'redneck' math and engineering I am using...there are others who certainly could answer this more accurately

    however you are on a GTX...your ECU may be different and not allow quite as much rpms? REALLY unsure about that!

    So if you stock hp is 185, you should be in the 225 to 250 range, maybe a bit more (I'm just guessing). I know your pistons are a little different, but I don't know about the cam and ecu.

    the gtx ecu only revs to 7600rpms and the pistons are cast.
