Sea doo 215 supercharger vs 255 supercharger

[skip707]

Does anyone know what the boost is on a 215 hp supercharger and what it is on a 255 supercharger

[skidoochris]

at 8000 the 215 is about 8+psi and 260/255 is about 10+

Thanks for the info, I put a riva blow off on it. Need to hook a gauge to it to confirm boost pressure, not sure if I am liking this blowoff, seems like it's letting a small continuous amount threw.

BOVs are known for leaking....at your boost levels,and the Scers we run..BOVS are a waist of time and money

[Meangreen05]

Alright, was just thinking with all the back pressure when letting off the throttle this would prolong supercharger wear.

[Snoman]

Nope..actually the opposite.believe it or not..BOVs are for Turbas not our SCers

[Meangreen05]

Ok cool, should of checked on here before spending a couple hundred...guess I'll disconnect the vac line and leave it alone.

[skidoochris]

you are correct it may help with sc clutch wear
that is still a debated subject here
but one fact is true, the hull of a pwc is a harsh place for a BOV
and you are likely to loose some boost from a BOV sooner or later
so for that reason alone I would not recommend one for a SC seadoo

IMO you should remove it and cap the hole.....maybe put it on feebay

[Meangreen05]

Well thanks, I'll get it removed...get a gauge on it and make sure I'm still puttin out good boost. Any cheap tricks to improve performance? Seems everything I look at starts around 250 and up.

what tune you running?
