Bleed valve - which way is increase/decrease?

Just thinking out loud as ive not really played with mine that much as it come with the engine allready set.

Thanks

anti-clockwise for more boost.

try 1/2 turn at a time 'til you know how much effect it has.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

am i right in thinking that the it is basically (and i am talking basically) a screw/bolt acting as a variable restriction. so the more restriction the more boost as the wastegate will be seeing less of the actual boost pressure?

so basically the tighter the screw/bolt is in the hole blocking it off the more boost you will see?

i also heard about a ball-bearing somewhere down the line.....could anybody please shed some light for me haha

Hi,
Nope it's a variable bleed off so it works the other way, you open the restriction to bleed off more boost to stop the actuator opening.
The ball bearing ones have a spring so you don't loose boost by bleeding it off you alter the spring pressure which alters when it sends pressure to the actuator

:) got it. so you are basically opening the size of hole in the pipe going to the acuator.

i get the ball bearing one now enal woohoo

Hi,
No you're opening the size of the hole to fresh air, that lowers the pressure in the actuator pipe, which stops it opening
