in reguards to the bpv threads, that really won't make a difference because once you step on the throttle and it's closed, it's closed. 7 threads out won't keep it from closing and cause a boost leak. Hell, last fall my screw came completely out and was gone and i didn't even know it.
Keep your hand in front of the bpv and give it some gas. See if you can feel any air leaking from there.

what bugs me, is the boost graph, it looks really unstable, correct me if im wrong, but shouldn't it show as a smooth line going up? Now, thats supposed to be either a leak or belt slip right? is there any other possibility of another thing thats not working properly that can affect my boost pressure? Its supposed to be in around 20.9-21 atmospheric pressure around 8psi...anything else I can check? Im running out of options...

We already did that....at idle its leaking air, but thats normal (apparently), once you give some gas it closes

Plus, during a WOT pull on the dyno if the spring is weak and the pressure is opening the bpv you should be able to put your hand over it and feel air leaking out. I guess that is worth a try.
you don't want to,that software isn't that great.

Ok so here is a picture of the impeller, it looks perfectly fine to me....also its about 45 to 60 degrees what I can twist the belt...
Is it possible to test just the blower to see how boost it is producing???
Hopefully tomorrow i will go to the shop to test the BPV with my mechanic ....running out of options

and if your belts aren't getting hot then something's up. after some runs mine are hot enough you can't touch them for more than a couple seconds.

You have to test it at the longest belt length between 2 pulleys. Where you are testing it is like 5" at the most between pulleys. You'll never be able to twist that since they are so close.
and you have to test it directly in the middle.
did you close down the BPV bolt to test if hte bpv is leaking?

we tried to tighten the belt yesterday.. it became a little hot, and the pulley bearings began to make an annoying noise. so we loosened it again..
I was worried about the noise from the pulley bearings.. I tought the noise came from there anyways..
man I'm getting frustrated..
Binder. can I get my tuner to call you today maybe?

I don't think so. The runners are designed differently if I'm not mistaken. Also the bracket mounts to the front timming cover not the plenum. Stillen is making a supercharger kit for the HR motor using a vortech blower. Why not use that option?
