im wondering if any of you are using a Tial 50mm bov on your sr?


-i just got my motor running the other day
-got the bov flange welded to my cold pipe.
-i have the vacum source from the throttle body t'd into the wastegate
-i start the car and the bov is wide open dumping all the air (i can feel it)
-when i pull the throttle gently it stays open,
-when i flick the throttle quick i can see the bov close and seal, then it opens again when i left off the throttle,
-the bov immediatly opens up again when the motor comes back down to idle.

anyone else ever have this problem? howd u solve it?

im thinkin the spring i have might be too soft and its not able to hold the bov piston down against the vacum, i duno

any opinions or insight are appreciated

you prolly have the wrong spring

you need the 11psi spring, if u don't have it already
