Powerflow exhaus t, o r electronic ignition. The ignition is a little cheaper, but I imagine take s more time to install. Is this correct? Which do you think gives the best bang for the buck, exhaust or ignition? I have both the PowerFlow (since 2006) and the ElectroAir (since last Novem ber). IMHO by and large the claims by their manufacturers are true. A power flow rep/expert just listed the high points of a power flow installation h ere yesterday. I wouldn't willingly go back to an OEM exhaust OR dual magne to system now but none of that is the crux of Brock's question. The questio n he poses is which ONE to buy with limited resources. If an exhaust system was blown out or a mag was bad at inspection it would make it simple to chose. I wouldn't replace or repair a failed OEM exhaust system with another OEM unit while at the same time replacing a good magnet o with an ElectroAir -- if I was on a budget. It just wouldn't make sense. And if both were in apparent good health now and I was going to chose whic h upgrade to do NOW I would probably chose the ElectroAir just because that mag could fail on the next flight while the exhaust system will more than likely last to a normal demise. Barry covered some of the additional expenses for a PF installation and som e of the same "hidden cost" issues exist for the ElectroAir installation. W hen you install the E-A, in addition to installing the supplied kit you wil l want to the point of need at least 4 and maybe 8, new plugs, a modified o r replaced ignition switch, and rerouted ignition harness for the remaining mag. None of this is real expensive but will add a few bucks to the bang/b uck analysis. Bottom line, I would make a decision, exhaust or ignition, on which system I felt would need major maintenance next - and upgrade that system. If I th ought both were absolutely equal in that evaluation I'd go with the Electro Air upgrade just because I have had more unplanned mag problems develop ove rnight than exhaust problems. If I misunderstood the question and budget isn't an issue get both next we ek and throw in an MT prop and Gary's cowl while your at it - you'll have t he whole package.

To avoid monopolizing the list, I was trying to condense my post as much as possible. Some other factors in the "it all depends" category would be the type of flying you typically do: If you normally operate out of an airport with long, paved runways and/or do a lot of cross country flights at higher altitudes, I'd have to say that (absent an unlimited budget, as Brent points out), you'd probably be better served by doing the Electroair upgrade first. If you fly out of a short, rough strip with crummy approaches or you do a lot of "puddle jumping" at low altitudes, I would make getting the Power Flow System a priority. Of course, Gary's cowl will look, work and fly great no matter what type of flying you do! All the Best! - Jim Shafer Power Flow Systems, Inc.
