Like it says. This is on an S5 FC road race car. It would be on my AST tank. I am concearned about damaging any internal coolant seals due to the higher pressure, but need to increase my cap pressure if I can. Thanks, Carl

 

On my racer 12A NA I use a 19psi quick release.
As soon as I get of the track myslef or the mechnic releases the pressure.

(Some recommend draining the coolant between meetings)

 

I do! ;-)

 

I run a 19psi cap.

 

i run a 22-25psi cap

 

Used it this weekend, found all the rubber hoses on my car that were old
