Anybody know the orifice size on these? How much Hp would they support on a dry shot? I am going to get some use outta mine as a dry shot. Are most purges(nos,nx,tnt) the same size orifice?

 

old purges were .063 new ones are .078.

Thanks Ricky, what kinda dry shot hp will those sizes support? Is there an easy way to tell the new from the old? I had this on my NX wet kit but decided I needed a second stage and picked up the parts to make a NOS 5176 for cheap.

 

anyone?
