for some reason my turbo has a v band flange on the charge side going to the intecooler. most of the people that i talk to say that is odd setup some body had to swap the housings I dont know anything about it cause i got from a guy who got it from a guy. so the thing is i got to do something . don,t want to cut it off the housing are to expensive to monkey with.so my neighboor works at a machine shop[ and is making me one out of billet . so now the ? is in order to make this flange and v band clamp work together the flange he machines has got to work with a v band is the lip on that tapered and do i need a gasket?

 

vbands dont need gaskets... thats the whole point of a vband is its two matched rings that are clamped together reeeeally hard by the clamp

 

okay but is the lip tapered so that the more u tighten the v band the tighter the two flanges mate

 

correct... the backside of both flanges is tapered, the more you tighten the clamp, the more it squeezes the two flanges together; so you will not need a gasket. thats the whole point of a vband setup, simple an effective and no need for gaskets. hope that helps.
