Turbo/blower Vs. hair dryer?

I was recently thinking about how the turbo works for gas engines. It forces air into the carburator, correct? Cold air+More fuel=More power, right? So, how much air really comes out of this turbo/blower? Is there really a great amount? When a tractor has the intake hose coming into the carb., how much pressure is really being inserted through the venturi of the carb? I was thinking that with the hot air module removed from a hair blow dryer, then put directly infront of the intake of the carb, it would act as if it is a turbo, right? I'm just a cheap farmer! Don't you guys think this would maybe work? Thanks

I have a turbocharged continental f162 in my massey harris 20. I tried unsuccessfully to blow the turbo through the carb. I balanced the pressure in the float bowl with a tube from the boost pipe. The floats slapped around like crazy, and then after 10psi, they turned into raisins. The throttle shaft will puke fuel all over the place because it is not sealed. If you get serious about turbocharging, convert your tractor to run on propane. This is already a pressurized fuel system already running over 14 psi. The propane convertor also has a port that can add more fuel under boost. plus, propane is about 114 octane, which will help protect against detonation.

pete 1468, procharger makes a super charger for the CARB Chevy engines and all the induction is what they call a "hat" on top of the carburetor where the air filter used to be. it is not boxed in. i dont know how an old tractor carb would take the boost though...might just blow it apart but i saw an "m" with a turbo on at red power roundup , but it was not inducted threw the carb. he said he was running about 10 pound of boost.

Pete1468 is right, you would need a pressure compensated carb. like on an airplane, otherwise you need more fuel pressure than your boost as your boost will keep your needle& seat closed, draw air through a carb

Think about it this way. Suppose your engine needs 500 cfm of air for its maximum power. CFM stands for Cubic Feet per Minute. That 500 number is very conservative but we'll use it because it's easy to work with. Think about about how much air that is. Imagine an air matress 6 inches thick, 5 feet wide, and 200 feet long. That's 500 cubic feet. Have you ever seen a hair dryer that would blow that matress up in a minute? It would have to be able to air up a matress 6 inches thick, 3 1/2 feet wide and 5 foot long in ONE SECOND. Better hang on to your hair, especially since I've used a very conservative number of 500 cfm.

i wish you good luck with that one. a average size turbo will pump more volume than a big air compressor.

i think it would restrict airflow, a blower/turbo takes a LARGE amount of air and compresses it into a tiny space. and it would have to be capable of making more then then 14.7 psi since that is sea level (average) atmospheric pressure.

Good luck blowing through a carb unless you have a pressure box around the carb. You can only draw air through a carb.
