Top Seven Reasons to Consider an Automobile=20 Conversion

 

  1. Cost to install. When compared to the = cost of a=20 new aircraft engine, a fully installed and properly functioning = automobile=20 engine can run 25% to 50% of its certified counterpart when compared = new-to-new.=20
  2. Cost to rebuild. When rebuilding an = auto=20 conversion, it can typically be brought to zero-time with all new = parts for=20 what a used yellow-tagged aircraft crankshaft costs, that=92s if = your core is=20 serviceable.=20
  3. Cost to operate. Most auto conversions = can be=20 operated on automobile fuel, cutting the per-gallon cost nearly in = half.=20 Modern auto conversions have tight tolerances eliminating the need = to add=20 oil between changes.=20
  4. Cost to maintain. Aircraft spark plugs = range from=20 $26 to $60 each. Automobile plugs are one tenth of that and = typically=20 require half as many. The same can be said = for virtually every=20 maintenance item.=20
  5. Convenience. Nearly every part you = might=20 need to repair or maintain your auto conversion can be purchased = from any=20 number of suppliers in your home town, even on Sunday, or are a = short drive=20 from what ever airport you might have landed at.=20
  6. Smoothness. Virtually every auto = conversion is=20 noticeably smoother than its aviation counterpart, reducing fatigue = on=20 components and occupants.=20
  7. Because you can. Why are we building an = airplane=20 in the first place? If all you are after is the performance offered = by=20 homebuilt aircraft, why not just buy one second hand?

There=92s a great amount of satisfaction = that stems=20 from standing back and saying, =93I built that.=94 The same applies = for an=20 automobile engine conversion, especially if it=92s never been done = before.=20

And remember, there are a lot of experimental = aircraft that=20 were designed (and proven) from the beginning to use an auto = conversion, so=20 many of the points for a certified = engine aren't relevant,=20 and many of the reasons against an auto conversion also apply to those = who=20 would consider installing an aircraft powerplant where an = auto=20 conversion is specified.
