i take my dp off so damn much im going v band. my question is this, can i tig the v band flange right to the exh housing? ive never attempted tigging cast. i know its prob not optimal but can it be d\one? or should i tig it to a 4 bolt dp flange and bolt that down

 

turbonetics does it.....

 

The v'band flange they put on cast is thicker then the standard flange.

what are you saying? they have cast v band pieces? so they are welding cast to cast?

explain further

 

My Innovative turbo has the vband welded to the housing as well...The flange is definetely thicker than a normal one used on an exhaust. Not sure where they get them from. The cast iron will still have to be preheated in order to weld the flange to the housing.

That would be the easiest way instead of having to go through the trouble of welding to cast.

Lucky for you, PT has done all the work for you! T3 exhaust Vband flange

 

i ordered a 3 inch stainless v band kit. im going to tig it to the exhaust housing...

 

every t3 housing i make a downpipe for gets a v-vand on it... its just so much easier than a flange... i use the standard weld-on pieces and have never had a problem with one... i think iv made a total of maybe 2 downpipes using flanges... i personally hate flanges

 

i just finished a turbo kit for a guy who had done it.looks Mig'd to me-but definitely not from the manufacturer.

thanks guys agreed flanges suck teh ********

 

where can i get the weld flange for the turbine v-band...you dont use a regular pipe one!!!?!?!?! also what filler rod do you use? thanks

 

to weld cast iron to steel you use a nickle filler. comes out really nice

More specifically, use Hastelloy W filler. There are about 50 different types of "nickel filler."

If you're welding what I presume is a .040" thick sheetmetal v-band flange (aka Marmon flange) to a ~.250" thick cast steel turbine housing, I hope your welder is good for 200 Amps. It's going to take a lot of heat to get that housing to melt.
You might want to fab up something like the PT flange posted above if your turbo will allow it.

 

i have a lincoln precision tig 185

i think it will be able to handle the task

 

i've done it b4 w/ my lincoln 100, argon/CO gas, and L56 wire .. welded a 3" steel vband flange to my sc61 housing.. its been holding strong to this day, 16k miles..

 

i already did it, its holding up beautiful

 

So what procedure did you use to do it?

 

i hit the housing with a wire wheel to clean it, then i tigged it on 150 amp draw with a 308 stainless rod.

 

can we get some finished pics? i wanna see this. i am also thinking about this going this route.

 

yeah i got a pic....

Then post it numb nuts, we wanna see lol

 

heres a 4" vband that i welded for Acosta Motorsports 3-rotor RX-8:


we use 3SMW or NiRod44, both are high nickel content.

preheating is key.

be careful welding these with 308. i tried 308 once, about 3 years ago on my personal car, and it didnt last very long. i havent had problems with any ever since.

i do 1-2 of these daily, if anyone has any questions feel free to pm me

 

Do you guys offer this option for t3/t4 turbos?How much extra is it?

for the t3/t4 turbos we generally recommend our vband adapter.
we offer the vband adapters in 4 and 5bolt, 2.5"($140), 3" ($150).
the adapters include a stainless vband TIG welded to the 4 or 5 bolt flange, stainless vband flange (downpipe side) and a quick release clamp. with the quick release clamp you only have to loosen the bolt and flip the latch

is there any particular reason you don't recommend welding a V-band fitting directly to the T3/T4 turbos?i'd like to do this,one of the main reasons being to eliminate the possibility of leaks developing between the turbo and flange.the ability to quickly unhook the downpipe isn't a really big concern to me.
