@Alessandro,
don't use those shims. Keep the turbine in parallel with the mounting rails, and align it with the pipe only.
I've talked with a lot of people about this, some with lots of viper experience
The intake seems to be off-center, thrustline with the rails and pipe in one line is ok and inline.

Hans is impossible for me align it with the pipe.
I've done a scheme... terrible!
