Jeff at SOS says no chance. Nate at CT says no prob. I guess we'll have to wait to see what CT says when installing the SOS pulley for Greg

 

Lol, it should fit on the shaft. Im thinking with it not "fitting" means it will need to be shaved or washers added in order to align it with the crank pully.

 

I'm in the same boat. Looking to run 11-12 psi with the CT kit with Novi 1200. Any updates on this?

 

I bought the 3.6 SOS pulley and sent it to CT. They machined it to fit their blower. I went to Evans and made 375whp at 10 PSI. So it is possible just needs a little work.

 

Thanks for the update. Any info on exactly what they did to make it fit? Was the mounting plate modified, different bolts used etc?

 

Thanks for the info... also in the same boat!!!

what pulley size would i use if i want to hit 12-14 psi (400whp-ish)

 

The only difference betwee the Comptech 12 series plate and the sos upgrade plate are a few of the sc mounting points and the center holes close to where the sc shaft is.

These holes close to the shaft are recessed so the tapered bolts sit flush with the mounting plate.

It would be easy to just drill the Comptech plate to do the same.

 

So essentially its a clearance issue with the mounting bolts of the blower to the bracket? Not necessarily an offset issue of the S/C pulley lining up with the crank pulley?

 

So you saying you just need to taper the mounting holes so that the bolts can sit flush with the mounting plate???

Does anyone know of a good place to get a pulley for my ct1220sl would like to be around 12psi

 

i thought about counter sinking the mounting holes on the CT SC Plate but was in a rush to finish the installation so we didn't have the time to make it work.

I have a SOS NOVI 1200/1220 series 3" pulley for sale. Brand new, Never used. $20 cheaper than buying it directly from SOS.

Per SOS website notes, it puts out about 12psi on NOVI 1220 units.
