I'm a big fan of VTTO's idea back in 2015 when they release their Garrett CHRA turbo, but apparently, they failed. It doesn't spool faster than PS2 and doesn't make more power either.
A successful turbo kit is a lot more than the concept, it's mostly in the execution.

Their stage 3 kit uses a cast manifold with a custom cast turbo housing and Garrett 3670R CHRA center section. Are you claiming they are using a cast housing to make it smaller than a standard Garrett 3670R housing so it can use the stock mounting and downpipe? If so, that would make this another hybrid turbo option similar to what Steamspeed is calling their stage 2.5. |
BMW cast turbine section and manifold in one piece, most of others don't. That means if you cast turbine section for bmw platform, you need to make manifold as well.
Normally stage 3 turbo does not include manifold. The closest platform is A45 AMG which use the same BW turbo from factory but manifold and turbo isn't in one piece. Their stage 3 upgrade (top mount) do not need a new manifold.
