WMI set up qestion

[GOFAST]

i had tested my car on the dyno.
but the results where not good, as you can see on the dyno sheet.
torque in low rpm did improve.....but my turbo had to much ware in the journal bearings.
and the compressor even had contact with the compressor house.



so the red curve is on diesel and the blue curve is with WMI on !!!
even I had a bad dyno run and I had to replace the turbo.
my question "does my WMI system work ? " is answered.
my tuner was amassed by the result with WMI.

well the turbo is replaced but I do not want the next step to be a bigger turbo.
so I am going to build a turbo compound system.
it has far better response.

this is a example from a system like it.


one of the biggest disadvantage is the heat it produces with double compression of air.
I was thinking interstage pre turbo injection.(injection before each turbo)
has anyone seen some one do this before ?????
I want to know if it's a good idea because there is no room for a intercooler in the second stage.(low pressure turbo)
and I do not want the heat of the first stage eider to compromise the heat of double compression V.S the heat produced by a single stage turbo by the same boost.
some were between 36 / 43 psi.
