I have searched around and called a couple of different shop and I have not gotten a really firm advice from anyone. I am looking to see what other people are using to get an idea of what size pulley I want to run on my new Novi 1200.

So if you have a Novi 1200 can you please post your pulley size and PSI that you are running.

Thanks

3.8" should hit roughly 10-11 lbs of boost. Call SOS. I have a 1200 and ordered that pulley. It is not installed yet.

 

I am interested in this as well. Chris@SOS mentioned that 3.4" would be a good starting point for 12psi at 8200rpms for the 1200 in my setup.

 

I have called SOS, Chris at SOS says they dont deal with the Novi 1200 all the time so they can only guess. He sold me a 4.2"

I had the Novi 1220 with a 3.8" I hit 9PSI before it blew up. (Self Lubrication is fail IMO) Sent it back to Paxton for a Novi 1200 Oil Fed.

I am under the understanding that the Novi 1200 moves a little more CFM so pulley sizes are exactly the same from the Novi 1200 to the Novi 1220.

Thanks for the input.

I considered going down this path as well (my 1220SL failed once) since I want to go to HPDEs. I exchanged emails or phone calls with SOS, my tuner, and Vortech last week. You can look at the compressor maps for the the Vortech Si and Sci trims at

Jamie@Vortech stated that the Vortech SCi trim is the same thing as the Paxton 1220 and that the Si trim is the same as the 1200. This includes the internals.
