REFLECTOR: Mag cooling

[slvegl99 at aol.com]

I have an XL FG with IO540 and the mag got so hot that it required rebuild. I have considered adding a heat shield but have not figured out how.

David,
The air from my armpit scoops is directed, via plenum, to cool the cylinders 
nd nothing else.  I have a Franklin with the alternator, mags and fuel pump 
n the accessory case.  I enlarged my belly scoop to provide cooling air to 
his area.  No problems so far.

> My Tech Advisor asked me to ask if anyone directs cooling air on to the
 magnetos?  I have two of them on the back of my IO-360-C1C and they
 currently get no air circulating over them at all.  Seems easy enough to
 bleed some off the ducts bringing air into the plenum. Is magneto heating 
 a
 problem for anyone?
