Only had about 4" of rise from turbo to waterline so made a new riser and mixer. All T316 stainless steel, machined flange to fit new turbo housing. With this I will be about 12" so hopefully save the new turbo housing..

1st pic is what it was..
Others are as I fab it.

FWIW

Very nice looking job.

Curious - any consideration or need for putting in a support on the downhill side, somewhere near that blue material? I have no concept of how heavy the piece is, just wondering.

Nice looking installation. You will want to watch your temps at lower speed to make sure that water is getting to the top of the spray ring. If it is running warm at lower speed close up some of the open area at the bottom to boost pressure at the top of the ring.

Highest temps will probably occur right before the turbo kicks in.

It really is not heavy and the bulk head is right there, maybe 6" from mixer so has support from there.

Will check for hot spots.

In my eye, truly works of art both yourself jwalka and others nice to have the knowledge and resources. Would having your water inlet up top help disperse the water more evenly and possibly avoid hot spots? nonetheless pretty work

"Inlet on top" the idea is to keep the water down hill from the turbo

I wondered the same but I think he meant put the inlet itself on the highest point on top instead of coming in at the side as the pic shows. Kinda makes sense if you have the room. On the support concern, if the engine is on soft mounts, being close to the bulkhead would add stress I would think.
