Title: Cooling the engine between rounds
Post by: GlennLever on June 27, 2018, 11:11:04 AM

Fans yep.

I know you do not want to suck air through the valve covers due to fire hazard.

I want to blow into one side and have it come out the other, what do you use?

Cheap electric leaf blower works for blowing thru engine.

i have been told the duty cycle on the leaf blowers do not hold up when the flow is reduced to flow through the burn down tubes?

Put more fuel into the engine and remove valve covers after a pass.  We use a leaf blower formerly to cool our converter now we cool our clutch with it has to have at least ten years on it!

Maybe because its now antique but my craftsman elec. leaf blower is about 25 years old. Well I think its actually been used to blow leave 2 or 3 times unless you count the ones that blow into shop.LOL

Glenn,

Wayne Sears has a small fan he made using some sort of blower motor.  It slips into the burn down tube, really nifty.  I made a light duty one from a cheap battery powered fan that I stick in between rounds, but I hit it with the leaf blower at the end of the day.  Kinda surprised somebody hasn't addressed making and marketing something.
