Long shot, but does anybody know/recognise this style take off on this exhaust housing of a mates turbo



The mating flange is curved, not flat so we are looking for ideas on how to mate up the exhaust.

We believe the turbo is off a Bentley of some sort

 

Veband fitment - plent of modern motors use them

 

V band flanges arent curved are they?
I have 1 at home and its flat and all the pics ive seen they look to be flat?

 

Stu im with you, I dont think its V-Band, I think its supposed to have a crush seal and a big clamp of some sort but finding out exactly what is prooving difficult!

 

IS there any markings on the casting?

 

Casting marks are M4 and that its a .63 housing

 

its like the opposite of a cossie housing.
that has the same chamfered flange except it comes out of the turbo, not in like the one above.
no help at all i know lol

 

I actually think its like that where the housing mounts upto the core of the turbo. Ill bring the housing into work at lunch and take a few snaps.
