I do appreciate you measuring the springs for me - I'll take all the information I can get.

Mine has 7 turns also...maybe the spring got compressed over the years it wasn't in use?

Anyway...how much is one of them Tial wastegates, anyway? Just kidding. :)

It is possible that the spring "relaxed" over the years, but usually the spring material is pretty resilent. It's possible though....

Glad I could help with measurements. I'll get some better measurements with my calipers after the holidays if you would like.

The Tial's are really a quality piece. I had no intention of getting one, thats why I bought the 1bar spring, but when I got headers installed, all the studs on the wastegate broke off, and at the time I didn't want to deal with that, so I decided to bite the bullet and I got a super deal on the Tial. I still have my old one that I am going to rebuild someday and sell when I get some time.

Colin,

Here are the measurements of my stock spring.

6.75" length
.202" wire dia.
2.75" od

This spring let the gate open around 11 psi

Good luck
