guys

i need some 2.25" vband clamps. ive seen a few people say obx vband quality is pretty decent.

if i really have to pony up the 80 bucks x2 then i will, but those obx's are a lot less

race parts solutions dont have 2.25...

thanks

What part of your turbo setup will the clamps be used.

I've used the cheap ones on my exhaust, and they work fine, but I wouldn't use them for a joint that will be under pressure (any coupling pre turbo).
I don't have any experience with V bands for intercooler pipe coupling.

They will advertise they are 100% stainless including the flanges... The flanges are not.
WTF?.... They really make ones for $80. ?? Wow.. what kind of precious metal are they?

ill be using these on the truck manifolds and pre-turbo piping

i think i want the stainless.. read somewhere stainless matches the "cast iron" of the truck manifolds better

keep the ideas coming

thanks

Pretty much everything they sell is junk.

Not necessarily. I've had good luck with ebay brands of stainless VBands. If you want it to seal and positively locate against the other one, just make the pipe inside the vband stick out from the end of the face of the flange and recess the pipe in the other one. That way one is essentially male and the other is essentially female. Much better seal that way.

LOL at that statement. I assume you have overpaid for something and now are jealous of those that have had good results with OBX

I have used the OBX v-bands and had good success with them on my manifold turbo setup. They worked great. Only issue i had was the t-bolt and nut giving up after multiple uses or torqueing down on them. I just replace that and am on my way.

Use them for pre and post turbo applications in various sizes from 2" all the way up to 3.5"

No issues.

As i said in the PM, the OBX Vbands that i bought with the alignment ring inside were twice the quality of any vband ive used before, thick flanges for the clamps, and thick extensions to weld too, means less prone to warping during welding.

I think i gave like 25 bucks a piece or something for them and would buy them again in a heart beat.

I used them on my hot side and like JAX04 said, they were real nice, the alignment ring fit perfect and they welded great. I used the 2.5" and got them on ebay

Plan on using them soon. Got to have the alignment ring, without it its a pain.

Cast irons have a lower rate of thermal expansion. Stainless steels (304) have a 30% higher rate of thermal expansion than mild steel. I'm building my manifold with mild steel flanges.

Using the OBX flanges as well. Only mild steel I found in 2.25". Mine came with the male/female alignment feature. Fit tightly together.

im using 2 obx vbands on my turbo kit.. working perfect

No need, just assemble your pipes like this:

I like this, it accomplishes two things in my eyes.

1. alignment

2. strength for when your hanging something off of it.

The v bands I was using before had a step on them to locate the pipe and you couldnt push the pipe through. I definately like that though, looks like it would be much stronger.

I welded MS OBX to my truck manifolds, over a year ago, they work great. Just dont over tighten them, I destroyed one clamp trying to use a 3/8 impact driver to tighten it. now i use a little lube and 1/4 drive ratchet. No problems.

killernoodle

You usually won't be able to push the pipe through as it sits. I always had to cut a couple slits in the pipe to shrink them, hammer them through the ring, then weld the slits up. I don't really trust a butt joint on a v band connection, I'd rather have a lap joint there and use the tube to positively locate the joint.

If you are doing that, wouldn't running a 2.5" flange over your 2.25" 16ga tubing be easier?
