Perhaps a noob question, but what's the advantage of running vband vs conventional flange?

I often see conventional turbo flanges loosening themselves after a while, will vband help with this?

 

ive never had a v band come loose. they use a lock type nut on them, and i cant complain how much easier everything is to work on/ & fab.

 

Does vband flanges come in 3"? I was told by a shop that if I want vband on my turbo and downpipe it have to be 2.5".....?

 

the main advantage is ease of service. 1 screw instead of 3 or 4.

 

vband housing come in various sizes from most common are 2.5 3.0" and 4.0" vbands most housing are going to be 3" vband

Depending on what kind of room you have you can weld a 3" vband directly to your turbo housing. As far as the shop goes. Maybe there is no room for a 3"?

 

another "noob" question...

are there any turbos that are v band compatible by default or does the hot side of the turbo need to be swapped out?

seems to me v band setups would generally be prone to leakage but I don't have any personal experience with them so who knows.

 

you can run v band on anything if you have the room. My turbo comes with a 4 bolt, and they make a conversion from the 4 bolt to 3" v-band. It's ALOT easier to work on.
Some turbos come with them, usually the larger turbos it's standard b/c they run larger downpipes. I run a full 3" exhaust and when you tear down motors alot the v-band conversion is nice cuz it's alot quicker, and they never come loose like the bolt flanges

 

most of the new precision turbos are going the vband route thy have them on the sc61 sc50 and few othr models now.

atp alos makes a stg 3 t31 vband housing

 

Thats who i got mine from, couldn't remember, atp makes all different size conversions check em out

 

If you cant get the vband hot side you can always have your fab guy do it for you

 

Correct me if I am wrong.But don't they also sell a adapter that allows you to run a vband on a 4 bolt or 5 bolt??????
