I found the variable main jet discussed on thesamba.com. It's out of production and it was for the 30 PICT. I've got a 34 PICT. Once I've got a mileage baseline, I'd like to try the Gene Berg Jet-A-Vator. It's a restrictor plate, plus.
aerohead -- So far I've found Full-boat-tail trailer with gap-fillers for Toyota T-100 pickup and 2011 Prius to get full boat tail w/ faired trailer that spun off from it, but I haven't found the earlier post referenced on the first page. But that's 38 pages anyway, so I've got some reading to do.
I've given some thought to taking engine air from a horn shaped scoop that runs along the drip rail as it departs from the template line. I tried to picture it in Photoshop but I wasn't satisfied. I need to get back to modelling in 3D. Until then just imagine sucking up to 600 cubic feet per minute of the air that's trying to spill over the edge. Do you think that could kill vortex formation?

The vortex formation will be triggered by shearing forces of tranverse flow where slower,higher pressure air alongside the body attempts to bleed off into the faster,lower pressure air above the drip rail.
The VW Transporter,as a 'square-back' type body won't produce vortices,and the configuration of their cooling air inlet scoop allows for outer flow attachment downstream of the ram opening.
With the boat tail,it will provide an exo-duct diverging nozzle outside of which the streamlines can even better blend together as they gain pressure.
On my bus,I never modified the inlets and the boat tail was just integrated into the existing curvature,especially on the roof.I drilled through the rear drip edge and used it as a hard point for attachment of the tail's skeleton.
