Steve Brown,
2) If you have a spring that is the correct rate but it has an OD that is smaller than the spring pocket are locators necessary? What do you suggest?
3) How do you determine the fuss points or surge frequency points?
4) How do we obtain the premium springs (which generally have very high pressures and rates) for profiles requiring less pressure? For example, in a marine application for a BBC I may have a hyd roller cam 236*/242*@.050 and .610/.620 lift. Not a radical cam. Only requires 140# seat and 340# open, but I will run it for say 45 min at 5000 RPM. I need a bulletproof endurance spring but the competition parts don’t usually come at those rates. What are the alternatives? Special orders? What is a minimun run for a special order diameter/rate
5) What can be done to increase fatigue resistance? Coating/polish?

Can anyone order dirrect from PSI and whats the minimum order for a custom spring ?

What are the best quality materials for springs that don't loose pressure?
