wastegate question

[usmusclekiller]

This probably sounds stupid but are wastegate flappers able to be pushed open by hand? I have a ihi turbo that has an internal wastegate and when i try to move the flapper open it wont budge.

On some turbos you can move it by hand, but it is kind of difficult. On my car I can't move it, but on my friends Grand National I can move it with quite a bit of force. I guess it depends on the type of internal wastegate and maybe the amount of boost that it is set for.

connect the wastegate actuator to the wastegate flapper.. apply about 12-14psi.. It should open then
