Electro-polished valve springs?

ss wannabee · 10-02-2007, 11:24 AM

I've been hearing a lot of good about these... What if you already have the springs you're running....can this process be done to the springs you have....like the dry-film coating? Or, is it done as the spring is manufactured, and can't be done later? What about the cost and performance of this method vs. coating the springs? Does it matter what material the spring is made from? Who does this? Thanks!

No responses? I was leaning toward HPC to coat my springs anyway....Thanks for looking!

SS Wannabee,
I worked at a lab that had an electro-polish tank. We used it to for stainless lines for ground support systems on the shuttle. Think of electro-polishing as the opposite of plating, as it removes a very small amount of surface material. (the higher points) The stainless would come out looking like it was chrome plated. I understand the process is usefull in adding strength by eliminating locations where stress risers might form that lead to cracking. (Like polishing rod beams)
The process was done in a tank (can't remember the solution) and an electrical lead was attached to the part and another to a couple of plates. As the current flowed through the part the electro-polishing would take place.

(at least thats the way I remember it from 31yrs ago)

I had a set of used dale earnheart industries springs that looked chrome they were polished so nice . The one race used spring from a restrictor plate cup car outlived a set of k motion springs by 28 passes . Of course they werent the same brand the dei was a Psi spring and the other was a k motion
65 runs from the k motion before I HAD to change them
I got 93 runs on the DEI -PSI polished spring before they HAD to change them .
