In addition, and on the advice of ZAC (Nicholas Heintz - this was the early days of the Rotax 912S in 2002, which presented new cooling problems compared with the 80 HP R912), ZAC sent me a wide fibreglass NACA vent which I installed under the main air intake aperture in the front of the cowl, right in front of the oil cooler radiator. It was necessary to cut a sort of rectangular hole through the cowl and fibreglass the NACA vent in place, but it wasn't hard to make a nice job. Perhaps ZAC still has some of these NACA vents. One important point with any of these vents: the gap between the fibreglass and the metal rad must be as small as possible without any chance of rubbing; otherwise, the air goes around the edge, and not through the rad. Thus, I suggest that you increase the outlet area at the rear-bottom of the cowl, and make a 1" lip as Bryan and Dave suggested. If that isn't satisfactory, you might pursue the NACA vent route in addition.

Most aircraft alternators are just automotive alternators with a more extensive paper trail. As far as alternator RPM is concerned, the RPM of the alternator will be the same as engine RPM only if both pulleys are the same size. Typically, the pulley on the engine is larger than the one on the alternator so the alternator runs faster than the engine. The speed ratio is the same as the diameter ratio. I don't know if my alternator is the same as the original Subaru unit or if the drive ratio is the same. It came with the engine from Stratus. The pulleys may have been selected to give the proper RPM for the expected cruise RPM of the engine.

It just goes to prove once again that we shouldn't waste time "fixing" problems before they're properly diagnosed and understood. Today I popped the top cowl, ready to remove the alternator - thinking "wouldn't it be nice if it was only a broken wire..." Only to discover that it was a broken wire! The main output terminal eyelet was broken. I'm pretty sure this happened when my friendly mechanic found my main terminal nut was not completely tight and he tourqued it up for me. But at the same time I think he bent the terminal eye back against the alternator to lie flat (I always in stall wires with a small offset bent into the terminal to keep the wire away from anything that could cause chaffing). This double bending on a large terminal must have started a crack which finally broke through completely. My repair is now a simple re-fit of the alternator feed wire or just the one terminal. Sweet. Not often problems pan out this way. While I was at it I determined that my alternator drive pulley is on the engine crankshaft end. The alternator has an equally-sized pulley so engine rpm is basically alternator rpm, which is excellent for my system. So my alternator research was not wasted. Now I know.
