I'm about to buy a pressure release kit and their are 2 rating available, just wanted to see if i anyone has any info on which kit is preferred on a standard C/R YB as more isn't always better?

Kit's are:

75psi cold or 85psi cold

 

75 psi is more than enough, I have 100% bog std pinto pump on mine, all of Ł24, same as the one that was on it for 200k miles!!

Tab how do you get the cover off or is it just damage it to get it out as you have a new one to go in?

 

Is there actually any need to have a high pressure pump? sure i read some where Sheedy dont use them???

 

No imo there's no need on 99% of cossies for a HP oil pump, if I was doing a lot of extended high revs in a restroked one I would but not in std/modified.
