Iim in process of building my turbo setup. Why don't cold sides use v bands like hot sides do? Just curious. Are there limitations there? (For the 1000-1200hp setups)

You cant put silicone couplers on 1200 degree exhaust pipe.

That part I know, obviously. Very obviously.

Someone just told me "to get the entire kit v banded" yet pretty much everything I see has couplers on the cold side and inter cooler and all that, except for 2500hp outlaw cars that v band everything.

Some people do v band their cold side. Not as many people can weld aluminum either

My complete cold side has vbands. I like it a lot more than the couplers

I like the idea of v bands on cold side, was just seeing that tons of people even the higher hp guys run couplers.

Thank you sir. Awesome car you have there.

On most cars it doesnt require v bands because boost pressure isnt enough to blow off the couplers. The big powered cars running extreme amounts of boost will blow the couplers apart hence the need for v bands.

HexenLord

V bands don't pop off or blow apart at 30 lbs like silicone can. Silicone couplers are notorious for popping off in the middle of a quarter mile pass.

Ok, then we may look into v banding mine, with the potential 20-25 pounds of boost.

I like the idea too because there is no posibilty that it will leak. And on top of that pulling the intercooler pipes will be a lot easier. Silicone couplers can be a pain in the *** at times.

It's just easier to use a coupler. There are Vbands cheapish on EBAY with an Oring in them specifically for cold side piping.

i vbanded my cold side but left 2 couplers so it had some flex. 4" vbands were $60, and a silicone and stainless clamps was like $45. Worth it for the ease of never having to worry about popping one off

Personally, I like the Vibrant VanJen clamps, or Accufab Clamshell clamps. They have some flexibility as opposed to a non-flexible v-band.

im running the vibrant vanjens. think i have 11 total. Not cheap.

I have one Vband on my cold side at the turbo because it was designed for one. BW S476. When I asked, guys said they just cut it off and used a silicone coupler. I wasn't about to whack the outlet off a $1600 turbo.

The rest of my cold side uses 3 silicone couplers. Of those, the only one that could blow off is the TB coupler. The others physically can't.

All that said, I have not run the car yet, so time will tell.

My new Cold side will have 2 V bands and 2 silicon couplers.

That being said my old cold side had about 6 silicone couplers and I didn't have any issues until I was trying to go faster than my 8.62 pass. And I was only loosing couplers on the turbo side of the intercooler(it was a restriction) Probably seeing 30 psi on that side. only 19-20 at the Engine

Dont forget, that unless your engine is bolted solid, and the chassis is solid, creating solid pipework can lead to fractures.

Silicone couplers allow some movement so are better than v-bands in that respect.

I would never ever use a solid pipe system with any type of flexible engine mount.

Wiggins clamps etc would be the thing to use there, although they are very expensive. I think there are similar cheaper options though.

But certainly on 3" pipework Ive used up to 40psi boost with no issues with silicone pipes and good quality hose clamps
A lot of making them work is just common sense. Proper hose prep and clamps, or add a bolted strain relief across silicone couplers.

Obviously the larger diameter the pipe, the more force trying to blow it apart.
