Correct Setup For Boost Solenoid

[GTR_Legend]

Guys,

After reading many threads and trying to find out how to connect my boost solenoid back up, i have done it but just want to ensure it is correct.

It was setup to bypass the boost solenoid l(hose from top nipple to bottom nipple) on the solenoid.

Below is a pic of what i have done, is this correct?

Any feed back would be great!

Also, While i am on the subject of boost solenoid's, is there any benefit of using an R32 GTR boost solenoid on my R33 GTST?

I was using it on my VL i used to own!

That looks correct. From the aluminium piping it goes thru the T piece to the turbo actuator. The T'd off pipe goes into the solenoid (as you have it) and then the other side of the solenoid goes to the intake pipe (ie it bleeds off pressure that the actuator see's.

Not sure if its std piping from alu pipe, but note that you need to have the restrictor inline between the T piece and alu piping.... else it wont work.

thanks fastrotor,

i ended up trying it on sunday anyway, its all good. The restricter must be in there as it is boosting correctly, 5psi then 7-8 @ 4500 and when the solenoid was bypassed it was hitting around 11-12psi. Feels alot more responsive and smoother now than what it was just bypassing the solenoid, just not as quick

Looking at getting a profec b now so all is good.

cheers mate

Glad to hear it all works ok mate. You could also look into a plug in computer that does boost control.... save spending money on both !

I use a link, and it allows you to program what boost you want at what revs. This is great and once setup, works great. I run 11psi on mine and at about 6000 rpm + i roll the boost off to 9psi.... i did this as on the dyno it would nose over in power...... so regulating to a lower boost keeps the wastegate open instead of closing and trying to mantain a boost level thru a small housing...... thereby extending your power curve due to keeping the turbo to motor backpressure lower.. So instead of dropping power at 6500 rpm i lowered boost and it maintained power to 8000 rpm !

Some helpful hints hopefully
