5 psi max supercharger

I have been gathering info on Seadoo's supercharger they use for their RXP personal water craft. This thing develops 255 horse from a 4 stroke...Check it out......http://www.jetskihaven.com/jetskipro...hp?prodnum=500

I found a pulley for this http://www.rd-performance.com/catalo...rger%20Pulleys

Just have to figure out mounting plus correct ratio.....yes I am looking to install on my SVX

Re: 5 psi max supercharger

I have a feeling that the SC might be a bit too small to handle the CFM requirements of a big 3.3 h6 but feel free to prove me wrong

(cause if you do then maybe I'll buy one too)

Re: 5 psi max supercharger

The intake side of the supercharger is 79mm, there is an optional flange to increase the bore to 88mm. This small supercharger, with a few mods, pushes a 185 horse naturally aspirated engine to over 270 horse, that sound like a possible way to add ponies without mass modding.

Re: 5 psi max supercharger

more air requires more fuel simple enough. There will be more mods other then just bolting it on and going for hell rides.

You also can't overspeed it to make more air so you need to see what it pushes in its normal useage range and see what its normal RPM range is too.

Once again I'm not saying it won't work but I do have my doubts. Feel free to prove me wrong.

Re: 5 psi max supercharger

It's from a four stroke.
How about installing twins for more engineering and giggles.

Re: 5 psi max supercharger

This small supercharger has all kinds of after market options. Stock it turns at 45,000 rpm on a 1497 cc 3 cylinder 4 stroke twin cam ( that is just about half of our svx engine! One for each cylinder bank, is the plenum actually divided on the svx?

I realize this is not a bolt on application, a few things are required: ECU
injectors
MAF
exhaust + cats
intake tubing
2 superchargers
brackets
pulleys
new plenum air box?
blow off valve
