Boost valves

[Sal Lubrano]

I was looking around for a larger boost valve and I can only find the one from PTS which is .555 and the .500. Is there any thing in between? I believe I have heard of a .521 but I could be wrong? I can't find it.

Sal ,be patient .We have something real nice coming out.555 with o ring seals.They are made from start to finish on a Citizen screw machine and the quality is unbelievable.Inner valve is then centerless ground.We will have them within 2 weeks.We tried no make them on the CNC but you cant beat the precision of the screw machine.We are also running band pins and 4l80e brake valves on the same run of 4140 pht.
