I'm still loosing boost when getting to high rpm. I pinned my crank. Changed the actuator to back of the blOwer. And still didn't help. Any more options ?

 

what does your air inlet and airbox setup consist of? Pictures would help

 

I don't know how to post pics bro. Has the k&n box. With the Maggie intake tube

 

Just use the manage attachments button in the advance reply.. Prety simple.. Or you could save them in photo bucket, then copy the image code from the pic.. What size pulley you running, are you still on a 6 rib belt?

 

The stock pulley with the TVs1900. Yes just 6 rib belt

 

here are some of the pics idk if that will be much but i can get more on here

 

Got it pinned and still the same. I sprayed sum belt conditioner and that help a lil bit. Is it possible my tensioner is slipping

 

How much boost are you losing? What is max boost? Is your bypass valve hooked up properly?

 

I see in another post Tarinitup, and Blown Chevy already asked these questions in another thread.

4psi down to 0, and tried pressure on the supercharger bypass.

I would try to wire the bypass completely closed just to eliminate that as a problem.

It could be the belt, but 4psi doesn't seem like enough to cause belt slip. Maybe I'm wrong.

When you lose boost, does it slowly bleed off, or does it chug like a belt slip problem?

 

My max boost is 4 psi and getting to higher rpm and slowly start to loose psi and when getting to 6000 rpm the boost is 0 psi it might be the tune
