i'm piecing together a single kit for my fd(t04s, 60-1, 1.0 hotside, ptrim). i haven't purchased the turbo yet and am wondering if it is worth paying a little extra for the v band? what are the advantages with the v band vs. standard flange? thanx in advance-garrett

 

with the v-band it allows a little bit of flex for the down pipe

 

so it basically acts as a flexable downpipe? do you have to weld a flange on the downpipe where it attaches to the turbo or does the band secure it?

 

It allows very minimal amount of flex, not tons. You have to weld a flare on the downpipe for the clamp to grab onto, or maybe there is a place that can flare the pipe?

 

Here is a bad pic of the components used to have a v-band connection

 

Depending on the gauge of thickness used for the pipe that is welded to the flange, you can have small cracks if you remove the downpipe often (like myself).
I've often seen small leaks with v-band connections over time unless the area has good support for the downpipe to minimize vibration.

There isn't much room for flex. It's not a flex joint or flex pipe. It's just a bit easier to slip the band around the flanges when they are mated together.

I personally do not think it's worth the extra bucks. Ol' bolts and flange with a gasket works just as good.
For my next project, I'd use a bolts n flange set-up.

i think i'm going bolt n flange. thanx for the info.
