  Jim,
  
  I have a Performance Engines IO-550-Exp in my ES. I've had no problems at
  all getting oil pressure. The longest I spent was when I preoiled the engine
  by pulling top plugs and spinning it on the starter. It took 8-10 seconds
  before pressure came up. Even after several oil / filter changes its never
  taken more than a few seconds. I'd guess something is wrong. Have you called
  Ron?
  
  As for horsepower I have the same question you do when running ROP. The
  Contenental engine manual doesn't seem relevant with the high compression.
  On the other hand, I did get data from APS/GAMI on operation LOP. For 10:1
  compression the HP = 16.6 x FF(gph). That is a significant jump from the
  14.9 factor for the stock 8.5:1 compression. I'm thinking efficiency in
  cruise is another big payoff for this engine.
