vn pulleys have one more rib than the sc14 supercharger, i supercharged my old vn v6 with one of those sc14's and i had to machine an extra rib on the supercharger pulley so the vn belt would match it

what supercharger are u using sc12 or sc14????

 

y do u want to change the pulleys to run more boost or to adapt it so it runs on the 4k?

Hi,

I have done this setup my self well its not on the car yet but..lol

 

Get a dual V-belt pulley for a 4K that had air con. You can use a normal single pulley and put a normal one bolted to it will work just need to cut the shaft for the crank off the one that is on the front. This will give you the space for a second V-belt.

 

Then you need a single row sigma air con clutch. I had a dual V-belt sigma air con pulley and it was JUST to wide for my liking as the pulleys were a bit thick so I felt on the SC14 shaft the nut wasn't screwed on enough.

 

Then just get 4K air con mounts or make your own and then bolt it all up :y:

 

So in short get a dual 4K crank pulley, single grove sigma air con pulley, and a air con mount for a K motor OR K series engine power steering pump mounts also work then your done :dance:

P.S. the SC14 I have the clutch on the front was stock and made by nipondenso and there other clutch pulley they has most run similar bearing sizes adn work as it is a industry standard so if you can't get a sigma pulley look at other aircon units and you will get something as the centre bearing size is sometimes the same.

Oh one more thing when I got my SC14 that has piping setup for a 5K the guy gave me a pulley that bolts to my crank one that is the same as the stock SC14 pulley so I can run a flat belt he said it was off a VW but not model so if you want the whole flat belt look at VW pullies.

cheers man i will have to look in to that!! did you have to change all your pullys to suit the flat belt? if not howd ya get around that cause your altenator would still be a V belt?

Hi,

I changed SC14 to Vbelt so no change to alt or anything.

 

But the VW flat belt pulley bolted to the front of the crank vbelt one so if you go to that option you wont need to change other belts either.
