New SBR-G50.. Messed up flapper or passage?

[crazykid]

I just got my new SBR-G50!! whoohoo! I opted to get it internally gated, and the turbine inlet/outlet ported. While examining around the flapper and decided if I was going to port anywhere around it (as I really want to solve any creep issues now before I install it). I noticed that it looks like the flapper door does not properly cover the wastegate passage. I noticed this while shining a spotlight down the turbine inlet to see if there was any spots to additionly port to insure a freeflowing wastegate entrance, as well as making sure the door was going to fully open to 90degrees (which it doesnt.. maybe only 60 degress). I would say its mostly around the hinge side and maybe about a little more than a quarter of a circle, but less then half, you can see where the door is not completly covering the hole. Almost like maybe its slitly offset or just does not match up properly or the passage was ported open just a little too big. Its not a HUGE gap, but definently enough where you can see through it and see the light shining through the inlet.

I would love to post up a pic but I dont got a dig camera and dont got computer cables for my camera phone yet.

What do you guys think? Is thing going to be an issue? Should I send the turbo back to SB to get fixed?

The best way I can describe it is it seems like around the hinge side of the flapper door, it was ported open just slightly to big, or the entire door is just slightly offset. There is definently a slight gap there though.

Most definitely send it back and get a replacement. If the flapper doesn't cover the path completely, you'll have spool up related issues.

Call Slowboy and tell them your problem. I'm sure they'll send you a new one.

Don't put the turbo on the car. That is totaly unacceptable and will lead to decreased wastegate performance.

Like posted above if the hole is not closed then it will not build boost. I had a similar problem but on my pte 50 trim I banged the WG a bit putting it on and it bend the accuator away form the housing causing the arm to be slack just a touch. It was a total nightmare trying to figure it out it would build boost on the highway in 3rd on a long pull I guess cause I was moving enough air at that speed. Its something you want fixed forsure. Make some calls ask some questions avoid install till said questions are answered.

Thank you everyone so much for the quick responses. I just contacted slowboys tech department so ill let you know what ends up happening. Im so glad I did examine the wastegate passage and door instead of just bolting it on right away. I only did cause I was worrying about creep and reading some of oldman's post about how to eliminate boost creep as well as the tech article from another member who he helped, and was considering doing some additional porting myself.
