  1. Well, I don’t trust the hype but will try a set of finewires, with a couple of LOP and ROP cruise test flights before and after the switch. If I see good enough improvement in performance, particularly LOP, then I will keep them. Otherwise I will go back to the massive and sell the finewires at a discount on eBay.

  2. The discussions and insights in this thread have gone in a somewhat different direction than I anticipated when starting it. But many of you have provided direct responses to my original questions, and the rest of the discussion has been valuable and insightful. So thanks to everyone that has participated. I for one have learned more than I anticipated. Hank Sent from my iPhone using Tapatalk
  3. I will have to investigate why the EDM-830 HP display matches the book while ROP but is quite different from the straight formula when LOP. Thanks Sent from my iPhone using Tapatalk
  4. Yes I am familiar with the formula, but does it account for OAT? I based my numbers on the EDM-830 in my panel, which I have been careful to tune, and its internal algorithm for calculating Hp. At such settings, my CHTs are always lower than at peak EGT and usually 340 or lower at cruise power. Sent from my iPhone using Tapatalk
  5. Thanks, that is the type of response I have been hoping for. Sent from my iPhone using Tapatalk
  6. Agreed and I do the same. I typically start leaning at 75% HP and 100+ ROP, then as I lean below peak the power has dropped to around 65%, but at that setting I see 9.5 to 9.0 gph, and rarely below 9 gph. My thinking, of which I am not confident, is that the fine wire plugs MAY allow for a more efficient combustion LOP and therefore smoother operations. For ROP operations I see little added value in the extra cost of the fine wire plugs. Sent from my iPhone using Tapatalk

  9. Thanks, that is exactly the type of feedback that I was hoping for. Sent from my iPhone using Tapatalk
  10. In my case it is typically 10 to 20 LOP at 65% Hp Sent from my iPhone using Tapatalk
  11. I clean, regap if needed, and rotate at oil changes every 25 - 30 hrs. The nearing the service limit is based on using the champion gauge that indirectly measures how much of the serviceable electrode is left. Mine are not cracked, just wearing out faster than expected and in need of future replacement. That is why I asked the group about experience with LOP and fine wire vs massive.

  12. No idea, my previous massive plugs lasted over 300 hours. On the current set only some are approaching the limit. Sent from my iPhone using Tapatalk
  13. For those of you that run your engine LOP, do you use fine wire or massive plugs? If you switched from one to the other, did you notice any improvement in LOP operations? I currently have Champion massive plugs that have less than 200 hours on them and some are close to their useful limits so I am considering changing to fine wires. I run 10 to 20 LOP at 65% Hp for most operations but will run 100+ ROP when I want to fly as fast as I can. Since I am considering the much higher purchase price of the fine wire plugs I wanted to reach out and ask about your experience with massive vs fine wire for mostly LOP operations. Note that I am not asking about massive vs fine wire in general, or LOP vs ROP, both topics that have already been widely, and enthusiastically discussed in MooneySpace and other venues. Thanks in advance - Hank
  14. If you remove them, then consider also removing the fairings on the lower wing behind them as the two just represent flat plates that increase drag when the front gear doors on their front are removed. I had mine removed 8 years ago and I am pleased with the decision and results. Hank
  15. Has Corrosion-X been applied to the airplane? If so, it may be the rain have pushed out some of the Corrosion-X film from inside the cowling.
