Your blow-dryer would be woring more like a supercharger, not turbocharger - but it's too small to be useful. It's not "Cold air+More fuel=More power". An intercooler, if used, cools air so it's more dense and ergo, more will fit into the same area and raise compression.
A turbo forces more air into a given space by pressure instead of cooling it, and this, in turn, raises the compression ratio. That's why they used to be called "altitude compensators." They were often used in high elevations where air is thin, which lowers compression, to compensate and get the horsepower back to normal. Now-adays, they are more often used to exceed the normal spectrum. Either way, for a good horsepower increase, the fuel delivery needs to be turned up as well - well - turned up in a diesel, or with a carburetor - rejetted, larger venturis, etc. Also, a turbo-charger is twin-turbine - one side being driven by exhaust gas, and the other charging the air intake. They are not equal sized - but are sized such that the exhaust driven turbine is of less volume than the turbine charging the intake - so the charge air always exceeds the exhaust flow. As RPM increases, the difference becomes greater and boost pressure rises - to a point where no more is wanted and it is relieved though a safety valve, aka "waste-gate." I am not an expert, perhaps someone else can explain it a little better. Rest assured, a blow-dryer will not provide enough flow for any gain.
A similar concept though, that does work, is a supercharger. It does the same thing to intake air as a turbo, but is NOT exhaust driven. It uses mechancial means, e.g. a belt drive or gear drive. Detroit Diesels have gear drive superchargers. Back in the 50s and 60s, add-on supercharger kits were poplular for cars, e.g. the "Paxton" supercharger. It was belt driven and actuated from a control rod inside the car.
