I was told by another member that they are made out of 80A, Valves are made out of the same material.
I have been toying with making a set of PCs based on what I have learned and was planning on using Inconel. After splitting one, I think I may do a phase 1 by just making a new upper half, with the injector lowered and angled. If I can find the time that is, lol.
I have been tuning after the swap and ran out of slot on the IP to advance the timing any further. You can run a good amount more timing with larger holes, it runs like a gasser now.
I also installed the EMP gauge and was very pleased to see that it is reasonable with the current vain setting, depending on how I drive it, the EMP is +3-5psi over boost, 1 to 1, or in third I can see more boost than EMP.
Cruising at 70mph (3500 RPM) EGT steadies out at 600*, with 4lbs of boost, EMP @7lbs. I am very interested to see how the larger elements effect it.
Ronnie, I will be ordering a sample of the new element I am considering using next month to be sure it what I want.
