  I haven't got my IVP done yet but if I were to do it over again to maximize
  for speed I would:
  1) put high compression pistons into my tsio-550 (helps cooling at least)
  2) get the engine blue printed and balanced and make sure the valves are
  perfect
  3) replace the intercoolers with a couple of tornado-alley intercoolers
  4) buy oversized compressors for the turbos
  5) (for climb) buy the cooling kit from Steve Martin
  6) get the extended exhaust tunnels from Jack McCallister and straighten out
  the pipes
  7) consider a cooling plenum
  8) bury all my antennas (oops, requires a new airframe and not tcad)
  9) get the fastest prop out there (?aero-composites? although the new
  Hartzell is not bad)
  10) wire the plane with redundant power so it's ready for Prism
  ....and be careful not to overboost
