  Those of you who are looking at using the TSIO-550 engine in the ES must be
  aware that the IV cowling, intended for the TSIO engine not only has the
  "Dolly Parton" exhaust bumps, but also has a one inch larger dia. intake
  openings for the additional cooling required  for the higher power operation
  capability at altitude. I used the ES cowling on my normally aspirated
  Lancair IV and it works very well - more than enough cooling - but if you
  use the TSIO engine, you should use the IV cowling designed for the TSIO-550
  engine. My $0.02 worth.
