Vband clamp help/issue

I have a issue with my vband flanges for my turbo setup. I ordered standard 2.5" dia vband clamps and the dia is fine, its the clamping part, my flanges are not flaired out as far as normal flanges that i usually see.

I have a few pics here to help.

Its hard to see in this pic but the flange on the left is mine, compared to another one on the right. Mine (left) does not 'flair out' as much as the one on the right.

To help tell that the 'flair out part of the flange' is diff heres another pic
Mine:

The other one (more flaired out)

and because of this issue it leaves a gap from the edge of my flange to the outside of the vband clamp. Here is a pic showing the gap, my issue because my flange isnt flaired out at far as normal ones ive seen.

Gap circled in red

So my question, is there a vband clamp that will work with this style flange? ive looked and couldnt find anything. thanks for any input

i have the same issue with my old turbo and down pipe. when clamped down, it never leaked, never moved. worked fine
 
Mine are the same way- I don't know of any other clamps that will correct the gap, but I have had no leaks either.
 
spray some copper gasket sealer on the mating faces before you tighten em down, they wont leak
 
There should be a gap, that means there is more room to tighten if need be. If that gap was closed completely that would mean the clamp is at its limit and cant be tightened anymore

no, you are mistaken on what gap im talking about, i understand that gap part, in that pic it is not tightened down all the way, im talking the flange to the outside of the clamp.

im bringing this back up, ive been in the process of modifying the headers for my car. got them all done, kit back on the mock up block.

some of the kit was a bit off, after i completely tightened up the clamps, i could still twist the pipe around. so again i think these are some weird flanges, unless a smaller dia clamp will work? im using a 2.5"

dont know if its twisting because of the shorter flange, or because the clamp is bottomed out still not all the way tight causing the twist.
 
Did you buy the on3 hot side? I read a thread on a guy with that kit and he had to grind away part of the clamp to get it to fit correctly. could possibly be the same problem your having :dunno:

no its not a on stage 3 kit, grind part of the clamp? not the flange part, b/c its like i need more flange, like the first pic of the 2 shown next to each other.

let me clearify

this gap is what im asking about:

not this gap:
Even though the clamp is bottomed out (not shown here), and the pipes will still spin with when i try to move/twist them.

now is this issue cause because the clamp is bottomed out (it is bottomed out, just not shown in this pic), so i need a smaller dia clamp? or is it because the flange part is odd/wrong and i need to change flanges or find the odd ball clamp that fits these? or is it normal to be like that?

I see what your saying. My only suggestion would be to buy a new marlin flange that matches the other and have it welded on.

my concern is if thats really the issue.. i want to avoid that because that causes me to cut apart the welds, putting new flanges on and hoping the kit all lines up when im done, a lot of work.
 
You try contacting some turbo kit manufactures or companys who install and sell them and see if they have any ideas on a v band that will work for your set up.

not really because i dont think its a turbo specific thing, and its really had to explain the issue over the phone with out seeing it, it was a lot to explain it in this thread with detailed pics and i still think i may have some people confused.
