    Advice on my 05 RXP

    I have done some research but am fairly new to modifying skis. My 05 RXP is finally out of warranty so now i can play with it a little more. I was looking to hit the high 70's low 80's without draining my wallet. I know everyone has a different opinion on the best way to do this so i was wondering if anyone would tell me what mods they would do to make this ski run that fast.

    High 70s and low 80s can be a big difference. How much are you looking to spend. Is 77ish enough or more looking for 80?

    I was intending on meaning the cheapest way to do it. I know its not cheap at all. I was thinking between 77 and 80

    The bare minimum for mid to high 70's... X charger $700, XS IC kit $430, 42# injectors $200, RRFPR $360 (will probably need a high volume fuel pump for the regulator to rise properly $90), 15-20 prop $300 (plus pitch if needed), 4" air intake $??? depending on what you decide to go with.

    ^This^ is exactly what i have done to my '05 RXP, minus the RRFPR (but plus the waterbox mod).....and Im GPS'ing 75.9 with 2-3 bars of fuel at 1100ft elevation. I picked up the XS IC used and everything else was bought brand new. I paid about $1100 (parts only, not for installation). Also, the prop surprisingly is hitting the factory max RXP's dead-on (8100) with NO pitching required

    edit: I originally started with only the SS wear ring (and at the time a 14/19 prop), rideplate holes filled and Riva intake grate...was GPSing 69mph.
