For those you who use V-band clamps, do you experience any boost leaks?

I found some pictures of some high boost cars using V-band clamps to hold the piping together. I'm assuming these are the same clamps as used in exhaust apps. right? If so do you silicone them or use a gasket or not or what?

Wolfe makes some with o-rings. I am sure there are others who do as well.

I used aluminum for my IC piping to save weight. I got v-band sets with male/female sides and o-rings from racepartsolutions. No leaks.

exactly what others have said...they use an o-ring to seal...

Try anywhere that sells plumbin fittings. Or SS fittings. Not like ace hardware, but like a big supply shop. Idk how the O-ring don't melt under this extreme of temps.

orings are only used on the charge (cold side) piping.

would beading the piping be as good, worse or better than o rings?

the v-band is a positive lock...it will NOT come apart.

I've seen some use vband on the crossover. Do they use a SS or Coper o-ring?

I used nothing. Some use copper RTV. they expand when they get hot and seal pretty tight.

Im talking about on the charge side, vbands are only used on the hot side right?

Now how does that work? DId you have a vband flange welded to your throttle body? more pics of just the throttle body with the flange if you could

We just welded an aluminum v-band flange to it...

we also had vbands at the turbo outlet and the intercooler inlet and outlet ports.

I don't have any great pictures of the throttle body flange...

Thanks bud.

I would suggest always using O-rings on the aluminum coldside V-bands. Not always necessary, but they are cheap and will help seal even a warped flange.

Copper RTV on the hotside intead of O-rings.
