Hi
I upgraded my vortech sc ..i had a 5" pulley and i upgraded it to. 3.4.
I woukd like to know if my BOV need to be adjusted?
Im supposed to boost 14 but i only boost 8-9 psi..
Do i need to tighten the bov since i upgraded?
Thanks!!

 

Don't touch it.

 

Was is my problem then? Why i only boost to 8 psi with my 3.4?

 

Belt slip? Boost leak?

Do you have T-bolt clamps at your aftercooler connections?

 

Belt slip.

 

+1 for belt slip. I always ask this question, what does your boost plot look like?

 

Wait, 3.4 pulley on a vortech, 8-9 psi sounds about right?

 

Im sure it is suposed to boost near
14 psi...!?
Would i hear a belt slip or see something if it is that ?
Yes i have t bolt clamp!

 

Also im on ap2

 

Belt slip is very obvious when looking at a plot of your boost. Did you observe this happening on a dyno? Or just by looking at your boost gauge in the car? If on a dyno, can you get the graphs from your tuner showing the boost curve?
