just a normal 50mm tial is all im lookin for
what spring rate for the 50mm you looking for
im not sure i dont really know how the spring rate stuff goes on a bov…i never had that kind of set up all i know is im looking to run like 18-25 psi on my new set up
spring rate is for vaccum at idle, go to ebay and search for a link. they have a link in their ads to tell you which you need specific
example i run a 9psi spring since i have low vaccum at idle
it says i would need an 11 psi spring cause i have vaccum from 18-21
