Triple Turbo Compounds Are Done!

Very interesting set up. You don't know what the sizes are though? any idea? Are they 3 medium sized turbos, two big and 1 medium sized, all 3 different sizes? Definitely takes the cake for innovation. Looks very clean too. Good job, I look forward to hearing more about this.

i'd like to see the routing of these things... i've seen one other tripple set up as a prototype online... there was a small high pressure and a medium high pressure turbo... i believe the medium one then force fed the large charger... could be wrong... which is why i'm surrious to see the routing deffinately amazing... roughly 650 hp and virtually smoke free... i love it

routing is in his picture really. The 2 atmospheric chargers both directly feed the compounding charger. which stays in a close to stock location and that feeds the compounded air into the IC. On the exhaust side, the smaller secondary charger is fed first and wastegated. And then the the exhaust exits into a hot pipe that feeds both atmospheric turbos and is also wastegated.
This set up isn't double compounding, its just using two chargers to provide air for compounding.
This is where I'm having trouble seeing the practical effectiveness, and would like to know a little more information. With 2 larger chargers feeding 1 smaller charger, it seems like there would be a bottle neck in the charger air side of things resulting in relatively high pressure in the first stage of charge air plumbing. If the pressure gets high there, then both chargers will have to work harder to supply air at that pressure and efficiency goes down. It seems like you would want like a 64mm and 2 71mm or a 66mm and 2 74mm chargers at most. and even that might be much. Since the 2 atmospheric turbos are running 4" and don't say schwitzer on the housing, I'm going to guess they are k31's. Probably with a 71mm wheel.
I'm just thinking out loud, seems like a cool set up, but like it might have some tuning/pairing issues to get it dialed. Definitely a good/interesting start. I'm also interested in the double compound idea like mentioned above as well, but it seems like you'd hit some bottle necks there too. And I know its been tried without much success, I looked into doing that before building twins a few years ago, and got steered away.
