Maybe but I wonder how much boost can they really produce? I think that is why you see the compound turbo set up more with diesel because they can handle, most of the time, far more boost and air volume than their gasoline counter parts and I think an s400, s480, ht3b etc would flow more air than even two smaller chargers working in parallel. But I am not a turbologist so I am not too sure. Yeah you can get 35 psi from an hx35 and an s480 but the s480 is pushing a TON more air. I am not saying it would not work I am just thinking return on investment.
I like everyone else here loves how Patracy thinks outside the box.
You've got to remember we're not looking for boost PSI, we're looking for FLOW. 800cfm at 20psi is better than 640cfm at 20psi.
I'd have to venture a guess that we're concerned with getting it to spool. But wouldn't "half" an engine with massive sticks provide plenty of the thermal energy needed to spin one turbo? I know my HX35 will launch into the stratosphere with just the ADR turned up.

I have thought about this setup also cause you can find another one fairly cheap. I beleive this is how Woodruff uses them in their triple setup two parellel being fed by a big turbo. With some bigger sticks shouldnt have no problem. Also Outlaw diesel has a setup on their 12 valve like this said they saw 600hp with out Supercharger but then they added the supercharger fedding the twins. If you do this let me know how this goes cause I have been thinking about the same setup.
not. the guys name was tim. he used to be a diesel mechanic for Blue Chip Diesel when chip was in hudson, nh (that business was sold to ben, a former employee, who now runs it as Northeast Performance Diesel). at the time he was running bully dog 8s which if you remember were extremely smokey and smoked at idle. the twins hit 50psi, but i don't remember what size they were. he did make good power, but a good a good set of compound twins and the newer injectors out there would have out performed this system.

oh, haha, i see how i worded it that you thought it may have been mine.
i forgot to mention that he had cut up 2 12valve manifolds and welded them together. i dunno why, since it's a 24v (the port shape issue), but they didn't leak. the pressure hose was radiator hose used for testing i believe. but i didn't see him much after that day and then i eventually saw that the truck was being sold...stock..

It would work if you were looking to make 500 to 600 hp.
A very crude way of sizing a turbo is to look how much power it will support. An HX35 will hold about 250 to 300 hp. So, if you were to make around 600 hp, then yes… 3 cyl could push the turbine. Now, as far as lag goes… you would have the same lag as a stock set up. But, if you were pushing that kind of power… then a big turbo isn’t very laggy. But a smaller turbo has less mass… so it will spool faster than one big one. (simple physics)
One thought… you would want to get a turbine housing without the divider in it. A large T3 type may work, or a set of Banks quick spool housings possibly.
I’ve built a bunch of “Log” style manifolds that flow well. If you can get someone to cut you a flange (1/2 inch steel) you can make the legs from cast steel pipe from McMaster Carr. It is very strong, very weldable, and cheap!!! Plus it will take the heat of the diesel. If built correctly… they look good, and wont crack.
