I'm redoing my downpipe with a tight radius bend to allow more room for a proper radiator and fan setup.

I'm not sure which flange I have here... as it seems a bridge between 2.5" and 3".

The OD on the flage (where the clamp locks) is just over 3". The ID of the actual outlet is 2.5" (allowing a 2.5" pipe as shown). I'm using a 3" clamp to hold it all together, which is weird as I would assume this is a 2.5" setup.

Should I be looking for a 2.5" vband flange or is this something different? I would love to use a 3" setup which I already ordered... but Im not going to be able to get the bend to turn without hitting the radiator

Thanks!

Edit: It appears the clamp i'm using is more like a 2.5". I ordered a few 3" clamps and flanges from ATP turbo and the clamp is huge on this flange.

 

What turbo?

 

Precision PTEB505-6765 (Billet wheel, 6765, Vband)

Turbine housing is a TH-GT2-65

I have a 3" vband clamp and flange here at the house and both are quite a bit larger than the vband flange that Precision sent me.... and their flange mounts up perfect to the backside of the turbo.

 

thats just a generic vband flange, if your running a precision turbo vband outlet, then it uses a specific vband flange you get from Precision. Precision vbands are tapered on the inside and meant to have the tubing slide over it.

 

precision t3 v-bands are 2.75"

 

this is what i use for my PTE5857 with T3 V-Band...it's a perfect fit to the Precision Turbo, and has the ability to either have a 2.5" pipe slip fit and welded to it, or a 3" pipe welded onto the little step you see in the picture...works great

 

You can use the below flange and clamp from ATP for the vband outlet t3 Precision housing or you can buy them straight from any precision dealer.
