Hello guys! just baught a Tial 50mm blowofvalve, Which psi spring do you guys use? havent drived the car with the new blowofvalve but when standing still and reving the car the valve dosent open it just shutters..is the standard spring to stuff for me then? i checked the diagram on Tial website and according to that i should use 11 psi spring, but if i remember correctly 11 psi comes standard?

Thankfull for help :=)

 

If you bought it new the box will tell you what spring you have, if not you match your vacuum pressure to the tial diagram and purchase that spring. if your saying you need an 11 psi spring and your having issues then you don't have the 11 psi spring.

 

It depends on what your vacume is at idle. That will tell you what spring to use.

Bingo I was to lazy to go search for it thanks Tom.

 

make sure you have 1/4" ID source directly to the manifold from the BOV, NO T's and NO using the stock connection point by the valve cover!!

 

Ok i have it connected where the stock sits! so thats is wrong? where on the manifold should i connect it? is there 1/4" outputs on the manifold? i belive they are smaller?
