I can pick up a real turbine from the scrap yard for $150, fabricate my brackets and pipes for pennies on the dollar, and THEN you would see a real improvement starting at 5 to 9 pounds above ambient pressures. Half a pound of thrust for that kind of dough is just....silly. But that's just my opinion. The problem is, you're not going to find anyone wasting time and money on this to research it all that deeply. That is such a minimal ROI it's *almost* laughable. But try this....
Instead of blowing that kind of money on that setup, one can easily get more than a pound of boost at WOT on one of these engines using a 12v battery powered leaf blower. Put a micro-switch on the throttle bracket that will spin the blower up from a fused power source tapped off the battery. You can do it for less than $40 between parts stores and the pawn shop for a used blower. Do you own research this way before you spend the dough on the "professionally packaged" kit adfter you have decided that it is worth it. You won't be so sorely disappointed when it *doesn't* work as expected and more than a $100 richer when you ditch the parts.
