Twincharging, Serious discussion.

You need to read this paper: TVS® V-Series Supercharger Development for Single and Compound Boosted Engines
I have a copy on the PC at home.
The results of the study I believe showed sequential turbo charging with a small quick spool turbo and complex exhaust and intake valving and control system to be the most efficient option. This gave the largest area under the torque speed curve.

Here is a bunch more photos.
Sandblasted and ready to cut back down and weld the runners.
Ready for IC piping and we are done for now, off to the dyno for a low boost tune and run in and then sort out the blower and go twincharged.

Well, it's complicated, the owner wants to feed the turbo with the blower with some odd valving system using high speed actuators and some separate logic based on boost pressure, pressure differential and rpm.
When he arrived I said that I kept the piping simple because it would be temporary, and the then pulled some actuators out and said "well....".
So at this point I don't really understand his exact plans, I will keep everyone updated.

In a sequential twin charged configuration without compound boost, Stage-1 Supercharger and Stage-2 Turbocharger is a perfectly viable method. It has been used by several automotive manufacturers and is the preferred configuration in the aeromotive industry.
Take for example, the Volkswagen TSI twincharge engine. The video below is well worth a watch.

What makes you say that?
