    PPG or Riva ?

    Who is having the best luck out of each kit?

    I like the design of the Riva exhaust and filter kit but do not like the idea of cutting the hull.
    This leads to which intercooler will work right?

    I belive I have made up my mind on the Riva grate and sponsons, still do not know which way to go on the bolt ons.

    I wanted to get these ordered, as I pick up the boat next week.
    New Red 05 RXP ( I hope it is one of the fast ones)

    Thanks Guys

    David

    BTW Cool Board!

    David, welcome to our site!

    The Riva kit looks really good, but it's too soon to tell what the results will be as the first batch of Stage 2 kits just shipped. I would imagine by the end of next weekend we will have some real world results on that setup.

    You are going in the right direction in installed the Riva grate and sponsons.

    David,
    Installed Riva's stage 1 last fall and it performed as advertised for me, I will be finishing my stage 2 install this week and hopefully be on the water this weekend, stay tuned for the results!

    I suppose the biggest differences between the kits are the IC and the exhaust. I like the idea of not cutting the ski to mount the Riva exhaust and IC, but if there is a huge difference then the Riva may be the way to go.

    I will use Riva's air intake as I like their kit better. With the hood it should flow a lot more cool air than PPG's

    The only other difference is the opas block offs. Is the Riva professional kit worth the extra money?

    Thanks

    David

    I like Rivas OPAS kit because it uses an O ring seal.

    If you have the extra money I would go with the Pro O.P.A.S Kit , Talk to Richard he has them cheaper than $300

    Jerry, how funny. It was that statement that got me banned from the PPG site.

    Did I mention how much I like the lack of censorship on your site today?

    That's exactly what pushed me into the Rotax Racing kits. That and the RR kits were designed and tested by the same company that built the engine and they are a little less expensive for the same parts.

    The things I like about the Rotax Racing setup:

    It's designed and tested by Rotax
    It's less expensive for the speed parts
    It opens the door for more mods if wanted (ECU)
    It raises your rev limiter allowing for different props to be used. Meaning smaller props with better accel that rev up to 8400+ RPM and still get great speeds.

    Things I don't like about the Rotax Racing setup:

    The clutch has the potential to be unreliable once touched
    The ECU is unknown factor (no BUDS, no info on it)


    Things I like conceptually about Riva Stage II:

    BOV / Don't touch SC clutch (although some say BOV causes more wear)
    It's an all in one kit
    Cleaner install
    Using stock ECU removes some unknowns
    Thru hull exhaust cleans up hull

    Things I don't like conceptually about the Riva Stage II:

    Stock ECU with no ability to raise rev limiter / increase A/F ratios for more performance. More potential for lean conditions. (Although they have mentioned a Stage III, so they must have some way around this)
    Have to cut hull for exhaust
    Have to run taller prop to make claimed speed (this has proven not so successful on RR kits, polus taller prop should diminish accel)
    Kit has some unneeded parts like the wedge

    After all the work testing we've done on the skis, I am having a hard time believing the Riva Stage II will hit 75 MPH with blistering accel with stock ECU. I am sure people will post that it does, but after my experience with the Riva Stage I and the RR Stage I, I would have a hard time believing it without seeing it. But it the kit actually lives up to its claims, it would probably be the way to go from a simplicity standpoint.

    ya im callin bs on riva doin 75 with a stock ecu as well, teh only way is if they have a super tall prop but it is still unlikely, unless they are testing on a river....lol

    They did their speed testing when it was cool out. Lets see what the summer heat brings
