Where to buy a vband for a GT47 compressor My GT47 has a v-band outlet on the compressor. Are there any places to buy a flange and v-band that works, or do I just get a 3.5" aluminum v-band kit and use 1/2 of it 
I found a source for the 5" turbine outlet, but haven't found one for the compressor yet

I'm not going to use any silicone couplers, except for at the TB interface

Problem I have is I can get a whole aluminum v-band kit (2 flanges and band) for 53.00
(or can order flanges for $22 and the band for $11)
That thing ATP sells (just one flange and band) is $69.00
Does a standard 3.5" vband flange work or is there something special about the GT42/47 that requires a different flange?

The one from ATP and the one from precision(the one I have) both have a locating flange(inner, slips into the compressor housing) and are O- ringed, so they are different than a standard 3.5 V band. Will a regular V band flange work, probably but not too sure.

wolfe's bands are intended to connect 2 pipes it appears. I'm pretty sure frcefed is correct, I recall seeing a locating flange on the compressor outlet which most v-bands dont have a provision for. Better safe than sorry 
Wolfe does have some nice 3.5" to 4" v-bands which I will use for my IC connections (I'm running 3.5" piping and the IC I have has 4" outputs)

I bought 90% of the parts, and they are fabbed it up, much like you are having your friend fab up your car. I have pics on www.psj.ls1tech.com, and can take more if you are interested. Brian M. from Precision Turbo has also been helpful with with questions about the GT47-88 in competition and it's max power potential.

My setup is quite different in positioning, especially since I opted to go with custom headers in lieu of manifolds. I have most everything either in hand or identified, this was one part that I wasn't 100% sure on...
All jabs aside, Speed Inc. sources parts froma lot of companies, so unless one was a ton cheaper and they it would work they most likely got it from Precision Turbo, since that's where the turbo came from.

ATP's part is much less....I'm trying to save a few bucks here and there....it adds up over the gazillion parts needed

That ATP kit is pretty nice
