Has anyone tried a 928 motorsports impeller? UPDATE: Pics of the old impeller->
Obvious boost leak- it can't make enough pressure. There are a total of 5 chips. I'm done buying used parts. I'm sick of everyone thinking they have premium parts, want top dollar and its been hammered to death. Either the seller Wild Bill (guy i bought this from) knew this kit was toast, or just doesn't have a clue and didn't know any better. Not to mention it was missing a critical $60 oil feed fitting, random hardware, and came with items that didn't even fit. When I sell someone a "mint" item, I make dam sure i've gone completly through it and that nothing is worn/failing.
Got my new impeller installed (not easy) and last part I need is my smaller pulley that I've been waiting a month for. This car better run like a raped ape or I'm gonna be pissed.

Hello, I bought a used Vortech kit a couple months ago. When I finally got it all hooked up, it made 1/2 lb of boost. So I pulled the belt off (used for 10 minutes) and got the car working NA because its my daily driver. When time would allow, I checked all connections, hoses, leaks and never noticed anything that would leak so much boost. Well, over the weekend I think I've found my problem. I inserted my snapon fiberoptic cam into the output of the volute and there is chunks missing on the impeller. I'm praying the inner housing isn't destroyed. I'm obviously pissed that I got screwed because I was told "this kit is good" and "made 7-9psi all day long".
I'm not shipping this to Vortech cuz they will want like $1100 to fix. I found this company on ebay (928 motorsports) that makes an impeller for my V1, Just wondering if anyone has any feedback on it? Is my LT1 a counter clockwise or clockwise rotation blower?
Thanks,
James

Just look at your own to see which rotation it is.
And I cant see them going to the trouble of CNC'ing something like that up for it not to work ?? Looks pretty cool

That's not good, wonder why it would lose boost?? Was the comparison done on days of same temp/etc.? Mine was only making 1/2lb before so i'm hoping it can only get better 
I'm not looking for more than 6psi, this car needs to be reliable.
Went to measure what belt length I need with the smaller pulley and the dam idler threads stripped when I rotated the tensioner. And of course its reverse thread, so i need to go buy a longer bolt/nut when if I get time next week. I hate aluminum threading!

how long does it take to get a pulley.I just couldnt wait for you to give us some answers so I finished installing my 928 motosports impeller into my powerdyne charger.fired it up and drove it to work this morning.you can definitly feel a difference. or I have been driving it with no charger for about a year now and it just feels great. hope to get some boost #s this weekend.the old setup was only putting out 4.5# of boost.
