Stock Nissan Solenoid Ratings?

Does anyone know if these solenoids can handle over 20psi???

[sewid]

I don't see pressure being the deciding factor instead it's probably duty cycle.

[mad082]

wat solenoid are we talking about? the boost solenoid? are you wanting to use it to boost from say 20psi up to 22psi?

[Robo's]

Sorry guys, yes boost solenoid

I think sewid is right, its not about what boost you can run, but the max duty cycle of the solenoid.

The boost solenoid would probably handle 100psi, but the second it is running at 100% duty cycle ie. it is always open, you wont be able to bleed off any more air, therefore wastegate opens and you reach your boost limit.

How do you test the duty cycle of it?

Problem is, im trying to close it with my IEBC but its not closing.

my sr20det solenoid has a duty cycle range between 8-92% from memory. solenoids do have pressure limits.

your having a different issue altogether though. what do you mean your trying to close it ? its a normally open solenoid isnt it, as in with no power connected no air flows through ? the IEBC should be opening it. if you have a normally closed solenoid (opposite operation) you need to make a jumper change from memory, but im quite sure nissan solenoids are all of the normally open type.

Im trying to close it to get more boost. The thing closes at idle but doesnt close under load. Trying to elimanate all problems to run more boost.
