turbo like fan for 4stoke engines

[Rollin310z]

just curious if it would be a good idea to put a small turbo fan on a small engine, more air flow would it help or it just no good

Unless that fan can push hard enough to compress the air instead of just blowing it into the carburetor, the mechanical losses (either electrically driven or purely mechanical) will nix out pretty much any benefit to it.

there are turbo fans made for car go to ebay they are little cheap fans that supposedly give a car engine 1-5hp so if it can give that amount of hp to a big engine imagine what it can do to a 4 stroke the yrun from 9-300 buck

its not worth it

:laughr how about a little strong pc fan

Those fans they sell for cars are the biggest ripoff. They actually reduce performance by inducing drag (having to move that fan blade takes not only more power to turn than you'd get out of it, but it also does not feed anywhere near the amount of air an engine sucks in on its own, much less having any chance of compressing it).

PC fans & those dinky things they sell are by no means a viable source of boost for even a tiny single cylinder motor.

If you want more juice, build the motor to do it. It's cheaper, safer, & less frustrating.

You would be better off with a Velocity Stack

Or if one like this will not work, you can make one.

When I has a kid the older kid across the street punched a 1 inch or so hole in the flywheel cover ran a hose from the hole to the carb.....not sure it helped but we thought it was cool...

The "intake fans" are completely ineffective. Besides that, if you pressurize air going into the carburetor, how are you going to keep it from pushing fuel back into the tank? It doesn't flow by osmosis...
