It doesn't matter that it is burnign in conjuction with regular fuel - it is burning. It is also not increasing the fuel efficiency as the engineers are already squeezing out everything they can get.
'perpetual motion' is not quite the accurate description although if it worked, one could be built using the techniqu. The proper term would be 'over-unity energy' - i.e., gettin more out than you put in.
Could you supply a link to the wiki article. I tried turbo charge and turbocharge but get no hits. I may be mistaken but a turbo charger works by compressing air thus allowing burning more fuel per charge. I can't see where it would result in an increase in economy.
It all comes back to "If it worked, cars would have them on it coming out the factory door". Would save the engineers blood, sweat and tears trying to increase their mpg by a few percentages.
It still is a violation of the laws ot thermo.

Being a slow day I got curious and did some poking on the question of turbocharging. Did find two source without digging deeply, one of them from wiki.

HowStuffWorks "How Turbochargers Work"
In this article, we'll learn how a turbocharger increasï½*es the power output of an engine while surviving extreme operating conditions. We'll also learn how wastegates, ceramic turbine blades and ball bearings help turbochargers do their job even better. Turbochargers are a type of forced induction system. They compress the air flowing into the engine (see How Car Engines Work for a description of airflow in a normal engine). The advantage of compressing the air is that it lets the engine squeeze more air into a cylinder, and more air means that more fuel can be added. Therefore, you get more power from each explosion in each cylinder. A turbocharged engine produces more power overall than the same engine without the charging. This can significantly improve the power-to-weight ratio for the engine (see How Horsepower Works for details).
-------------------------------------
Note that "more fuel" bit. It comes down to: you can use a turbo to get more HP from an engine (at a cost in fuel) or you can use a smaller, lighter engine to get the same HP (from the same amount of fuel). There is no increase in economy in either case...well, I suppose hauling less weight in the engine compartment would add a bit of economy but then you have added a bit more work for the the engine to begin with so...

Turbocharger - Wikipedia, the free encyclopedia
Working principle
A turbocharger consists of a turbine and a compressor linked by a shared axle. The turbine inlet receives exhaust gases from the engine causing the turbine wheel to rotate. This rotation drives the compressor, compressing ambient air and delivering it to the air intake manifold of the engine at higher pressure, resulting in a greater amount of the air entering the cylinder. In some instances, compressed air is routed through an intercooler which cools the air before introduction to the intake manifold, as the reduced density of hot air will cause a loss in power gained through turbocharging.
The objective of a turbocharger is the same as a supercharger; to improve upon the size-to-output efficiency of an engine by solving one of its cardinal limitations. A naturally aspirated automobile engine uses only the downward stroke of a piston to create an area of low pressure in order to draw air into the cylinder through the intake valves. Because the pressure in the cylinder cannot go below 0 psi (vacuum), and because of the relatively constant pressure of the atmosphere (about 15 psi), there ultimately will be a limit to the pressure difference across the intake valves and thus the amount of airflow entering the combustion chamber. This ability to fill the cylinder with air is its volumetric efficiency. Because the turbocharger increases the pressure at the point where air is entering the cylinder, and the amount of air brought into the cylinder is largely a function of time and pressure difference, more air will be forced in as the inlet manifold pressure increases. The additional air makes it possible to add more fuel (if a turbo is attached without any other engine enhancements it most likely will cause the engine to run lean -- too much air, not enough fuel), increasing the power and torque output of the engine to about 15 to 40 percent, particularly at high engine rotation speeds.

Again note the "more fuel"
I can see nothing either source that mentions 'economy'.
