snorkel to cool alternator

[Jurgen Amtmann]

Can anyone tell me where I can find the small snorkel that goes into the cooling air inlet, then connects to a hose that blows cooling air over the alternator?

I Jurgen,

Darrell Reiley (LifeofReiley on VAF) used to have some aluminum flanges for sale for 3/4" tubing which were perfect for this sort of application. Send him a PM, he may still have some left.

I used the black plastic ducting left over from wing wiring. Just drill a hole sized to capture the ducting in the air inlet ramp, and direct the duct at the alt., or mags too, zip tie the other end to anything convenient in the area.

Hello Jurgen,

I used some SCAT-4 Ducting and Aluminum Flanges from ACS both on the inlet for the alternator blast tube and on the back of the baffles for tubes to each mag.

As stated above, use the corrigated tubing left over from wiring. Located the cooling tube on the right coloing intake,above the alternator, secure with rtv and wire ties. There is sufficient air pressure available to adequately cool the diode pack at the rear of the alternator. Dan
