    Get a Synapse Engineering BOV. I had an HKS on my 500hp turbo car but it wouldn't activate until 12psi. Then I got a Synapse and it was light years better. The Synapse is like a pneumatic cylinder and activates at <1psi. Much more efficient and easier on the turbo. If used as a bypass valve (output run to the intake before the TB), it will allow more air to the engine when not under boost, further increasing efficiency.

    Do you plan on upgrading the IC? if so just do them both at the same time, if not you can get the R&D Tial BOV kit for your SVHO and be all set. Best way is to tap the manifold for the vacuum line but if its stock and just a BOV then you should be able to get away with a splitter.

    are the BOV necessary for these motors ?? any gains besides a sound?

    I know it sounds like a stupid question but I was told not to get one on my old seadoo because they will make the bearing wear faster on the SC... I would love to pick up a BOV for my new svho..

    The BOV will increase the life of the SC. Every time you are at full boost and let off the throttle rapidly the TB closes and the air then has no where to go other than the SC compressor wheel.

    Is it 100% necessary... no not really. But here's the thing, a BOV (I recommend HKS) will prolong the life of your clutch. The Yamaha and Seadoos have very different superchargers, so even tho adding a BOV isnt recommended on a seadoo, it is a smart investment on the Yamahas.
