However, I still kinda like DG's earlier proposal of allowing open boost
controls, so long as the turbo(s), oiling systems, and housings are not
modified.  Or something like that.  Simplifies the rules considerably,
and gets some goodwill from the turbo community (though those who have
already built DSM's with backdated turbos will still have to spend some
money).

I agree, because a turbo is NOTHING more than an air pump.

And since SP modifications allow as MUCH non-mechanical modifications as
possible to increase intake airflow, then that surely matches a turbocharger
being allowed to move as much air as mechanically (stock) possible.

As much as FS is really designed for the GM V8, the same will eventually
come of the "cheatin' turbo" cars as well.

Right now, BSP looks to be a promising home for these cars.

Within the design of the stock housings, let the turbo guys/gals move as
much air as they can.

The downsides to this will be that some cars will be prone to serious lean
conditions, overheating, or any number of problems, which THEY will have to
live with as manufacturing issues that none of us can do anything about.

Second downside..the more air you attempt to move thru a turbo (past stock
values) the less efficient it will become, adding serious amounts of heat to
the intake charge.

So..the 'magic' power in this open upgrade is NOT all that much.
