I know Joe from the Mazda forums.. he is a stand up guy

Eh, I made my own, I'll let you know how it works.

Running a $6 one from ebay. It worked to an extent. I think I need a bigger spring in my wg. I could get @ double my wg spring. Think it was a 5# and I could get up to about 11# with it.

I thought that's all you could do with a mbc, double the spring.

Usually it's right at double what you can make until you apply pressure to the top port. I've made up to 15lbs on a 4lb spring doing this.
