Hey all,
As some may know, I am in the process of fabbing a way to do the AJPTurbo boost regulator mod onto my EPP charge pipes. To my knowledge this has yet to be done.
I will not have this complete until sometime in January but wanted to share current progress.
I ordered a TiAL MV-S wastegate for the wastegate. Per the specs, the inlet Vband should be welded to 1.75" OD pipe... this is where the issue occurs... the Vband is stainless steel and must be welded to stainless steel, the hotpipes are aluminum... what to do?
To correct this, we need a way to connect aluminum and steel. This is where I struggled, I started by thinking of just using radiator hose as many have done on stock pipes, but was not feeling it. Then though of getting matched vbands , one set in stainless steel and one in aluminum to mate the pipe, again this seemed like it may not work, and would cost atleast $60 to test.
Cue the third idea... small section of stainless pipe, welded to the wastegate Vband, pre-bent aluminum pipe welded to the charge pipes, and a silicon hump connector with tbolt clamps to secure the pipes!
Today I did some prefab work, as I finally have all the parts (I can share the info on the parts later, with links, if requested).

I have attached some mock up photos. I will need to shorten the aluminum pipe, and weld one side to the charge piping. On the other I will need to either weld back the section with the bead roll, or bead roll at the cut. For the stainless joiner I will simply put one end in the clamp. Yeah other end will be cut and welded to the Vband.
The hump connector is rigid enough that everything should be supported with ease, but will allow for slight movement with the engine as well as slight misalignment of the pipes.
Pics attached. Comments and suggestions welcome. I will update once more progress is made.

2x Hose clamps for the brake booster line to secure on the barbs
1x Hose clamp for boost gauge line to the cross barb (I left it unclamped on the gauge, and have seen no issue)
To be honest, with barbed connections, the clamps can probably be skipped as a whole, but I feel better using them, just in case.
