    Which supercharger should I get?

    I have a 2006 Seadoo Challenger 180 and I need a new supercharger, I'm wondering which one you guys think I should get based on my modifications.

    1. SRX-CD-14/19R Impeller
    2. I'll probably be changing the air intake, it's stock right now

    I was doing 47mph GPS and maxing out at 7600RPM with a stock supercharger, I'm not cavitating or anything and the boat is fast out of the water.

    Thanks guys.

    You could go with the Riva Gen II with no other modifications

    Check it out here

    Or the Riva S3 but you would also need 42 lb injectors

    Injectors

    what kind of boost does the Riva S3 SCer produce at 8100 rpms? I'm looking to upgrade my SCer on my conversion and i'm not sure what I should do. i don't want to add a RRFPR or aftermarket ECU just yet, but i don't mind changing injectors.

    sorry to hijack the thread, i think this might add some more info on your topic too.

    Thanks guys.

    also, i'd go with a 4" air intake, cheap and simple way to feed the charger more air. plus, everybody is doing it.....

    Thanks for the advice Jerry, I'd like to go that route but I don't have the money, I need the whole supercharger and the $ really adds up, it wouldn't be so bad if I just wanted to upgrade.

    Thanks Ranger, 4" it is, I'll start researching that while I wait for my new supercharger.

    Ranger, 10.5 is the norm. I've seen as high as 11 psi on a cool day.

    This would be a great option for you.

    Sorry, didn't realize you needed the whole supercharger.

    here you go: http://www.4-tecperformance.com/inde...oducts_id=1160

    it's a straight-forward installation. i know you can buy the pieces individually, but why go through the effort? plus you're supporting this site.

    I'm the one that needs the support, this supercharger failure is gonna cost me over $2,000 now. I just wanna get it done so I can take my daughter out before the damn winter gets here.

    I got a jetboat so it's probably not gonna be exactly the same parts as for a Jetski, I'll need to do some research before I do the intake on my boat.

    I think I'll be ordering the stock RXP supercharger, I assume the price on this site is reasonable. The mechanic quoted me $1200, he's nuts...
