    Contact Extreme1 on the boards..he might have a hp500 for sale...you could contact Whipple and put one of their blowers on..or do like we did ..pull the 496 out and opt for the blown 588

    Do a search on here for 496 HO and start reading. This has been asked SEVERAL times and lots of the info you are looking for is already here.

    Buy a different motor. Don't waste time and money. It'll save you more in the long run. 500 HP or a 525

    Disregard that. ^^^^^^^^^^

    You can get plent of power out of your current motor without the extra cost of re-rigging the boat. A few have done was is suggested above and only gained 5mph - if that - for their trouble.

    There is alot of good attributes to the Gen-VII motor. It's just different enough from a Gen-VI to scare some peeps around here.

    Replicated cathedral intake ports.
    Better cooling.
    NO DISTRIBUTOR.

    There is plenty of good exhaust systems, which is where you should start. It will already be a gain and makes the motor ready for any further upgrades. You can't get more air IN if you can't get it OUT.

    Whipple can re-program your ECM for better mixture, timing, and power increase.

    I bought an extra set of heads to do bigger valves, since people will sell these parts pretty cheap. It's nice to have spares.

    1) change exhaust Dana or CMI
    2) do the whipple ecm upgrade
    3) get some more air into the motor compartment
    4) try a labbed prop
    I installed extra vents into the Warlock got some more COOL air into the more ..it picked up.....I did everything except the exhaust ( removed the "turbonators" off the exhaust) ....

    We put the same motor into the Eliminator and it ran good..lifted the hatch about 2 inches on the motor picked up RPM's ....We tried this on Exteme1's Laveycraft and it picked up some RPMS also...

    I was going to mention the TURBULATORS, but forgot. Thanks for bringing that up. That was a "feelable" change in mine. Sound also. It has been dyno'd at 7hp difference, but it sure feels like more. Taking a 2.5" restrictor (turbulator) out of a 3.75" hole definitely helps flow.

    Of course there's always the Raylar kit you could put on, but it's not going to be the least expensive option.

    Yeah, ask the other guy on here that went through the cost and effort to change to that - for 5 mph.

    I have 04 katchina with a 496 ho. After looking into what it wold take to make it go fast i found out nothing. The 496 ho is a great motor the way its is. Not a good motor to build up, so if you want go fast change motor. Or do what i did, I bought a runner bottom that goes well over 100mph.
