What is this part?



I've heard it's some type of Boost Control thing...

 

Boost control solenoid.

 

correct ^^^^

 

Ahh, I was close.

What's it's purpose? I know the 2.2L SC swaps don't utilize this.

 

Bump.

Someone PMd me asking where this thing goes...

 

I know it's wikipedia, but it might help

its mounted to the right of the valve cover

 

It is what controls the boost bypass valve i think

 

Its for the factory boost gauge on the SC models.

 

it allows the LSJ PCM to do things like boost reduction in first gear, etc.

 

no it is not. the peice shown is a boost controll solonoid, used on supercharged and turbocharged applications through various gm cars. they are turned on and off via the pcm, they controll the wastegate (turbo app) or in this case, blower bypass valve. the boost gauge is a signal comming from the pcm and the pcm uses the map sensor for that.

 

Oops my bad. I am no longer supercharged and I was certain that it was the solenoid for the boost gauge. Thanks for clarifying!
