I still cling to the scientific principle of repeatable testing to prove or disprove a theory. If people with decades of doctorate training and expertise can be surprised by results of actual testing instead of conjecture of "common sense" I'd still think that I could also. Even the dumber sounding "acetone improving fuel consumption" idea was tested and disproved. Without actual testing nearly all ideas will be shot down and forward progress of anything will be slowed exponentionally.
I agree it sounds like it would useless and a waste of time, but I refuse to come to a hard and fast conclusion without testing. If anyone can find the or do the actual testing we'd all be better off.

Better off as in back to the already known "It does not work".

Would an eletrical supercharger help the turbo spool up faster I know you not making any boost but it could help the turbine turn a little faster when your at sand still. Am i right or wrong...

A VGT would help your turbo spool faster. An electric fan might help it spool, but then it would act as a big restriction.

Wrong, it has airflow but no pressure.

Even at idle the OM617 is pulling 40cfm. By 2400rpm (When the engine should reach full boost at WOT) the fan is already a restriction.

This is about as close as it gets. A 3.0L dodge.

Is installing a VNT Turbo easy???

No. But considering there is zero value in an electric "supercharger" and a VNT makes a huge difference in performance across the board, a VNT is a far better value.

It's not hard once you get an adaptor plate.

I don't think an echarger would be a means to get real power but I do think it could be installed in such a way that it could help spool the turbo faster and not obstruct the air flow on the top end. Every year when I install a new air filter there is a definite difference in off the line performance as well as quicker spool time. If you connect the echarger to its own air filter and run it in parallel to your existing air filter you can reduce your air intake pressure drop at lower rpms and possibly maybe 1/20th a psi off the line (even though it would blow some air out the primary filter).

You could also use a double pole double throw relay to activate it and while its active kill the field coil in the alternator. This would eliminate alternator parasitic losses . Of course it would only be good for short bursts but once you get the turbo spooled these engines aren't that bad with out any assistance.

The air filter would be the path of least resistance for the "supercharger's" airflow.

If your dirty airfliter is that restrictive you should consider changing it more often and/or getting a filter minder.

Well the point is it would take some positive pressure to push air out of the primary filter and there would be positive pressure up until the engine demand equaled the air flow provided by the echarger. even after engine demaned exceeded the airflow provided by the echarger it would still reduce the slight vacuum created by the primary filter. This slight pressure instead or reduced vacuum would help build boost. Since boost helps build boost you would have a turbo that spools more quickly.

You would have better results to put it before the air filter to help overcome the pressure drop across the filter. Even that is a waste of money.
