    Supercharger inlet

    I'm planning to make my own intake for my 2012 FZR Sho and was wondering what is the supercharger inlet that way I get the correct coupler for the 4" intake piping

    Use a 3-4" elbow coupler (reducer). I recommend you use a thick rubber one, not silicone. The silicone ones tend to collapse of you're sucking in enough air. I used one like the one in the link. I found it for less somewhere else, but can't find it right now.

    Silicone ones are good for positive pressure, but are soft and tend to callapse when air is getting sucked through.

    I ended buying all the parts locally down here in Miami. and just got the 3-4" 4 ply silicone reducer and seems to work fine. and the fitment good. all I did was cut off like 3/4" from the 3" side of the coupler and used a 90 degree 4" aluminum pip and fit perfect with a 8" length air filter. feel like I got a lil mid range. but now I have cavitation out the hole.

    DId you resolve your cavitation issue? also do you have any pics of your set up. I am trying to help a buddy with his so curious to see how yours looks.

    I ended up buying a R&D cone and that helped but didn't eliminate the cavitation 100%. but it did help. haven't done anything else because my ski is in the shop
