The CJ-6As turned 2100 RPM to stay up and burned more fuel and oil. Of course we could have increased our power a little maybe 72/74 % and left the C6-As behind, that's what the dark side would do, but we pulled the power way back so we all could stay together.

Aeroshell products are very easy. I have about 9 litres of the phillips left, and was wondering if I'm doing any harm/commtting a sin if I add some Aeroshell w100. Or would you recommend I drain all the phillips before.

Dennis Savarese" Subject: Re: Yak-List: Housai to M14P Conversion And how many horsepower does the Housai develop at 2350? 285, right? Now divide 2350 by 2900. What percent is that? 81%. Now multiply that percent times 360. What horsepower is that? 291 horsepower to be exact. Hummmm....aren't they amazingly close? Same cubic inches. 620 cu. in. Only 1/10 point difference in compression ratio too. Specific fuel consumption for both stock engines at the same power settings is going to be pretty darn close. It's the nature of the beast, unless of course there are custom modifications to the engines. Propellers do make a difference. Put a pair of Chinese prop blades into a Russian hub, (the blades are interchangeable with the Russian paddle prop blades). Then go fly a specified test plan at the same percent of power (Housai 285 and M14P powered CJ6) and document the results. I'm sure everyone on the list would be interested in the results. I think some of the folks on the list thinking of making the change will have difficulty justifying the 50K upgrade, particularly after the results are posted.

Before that, I had the pleasure of doing some initial training in one with the larger M14 and a two blade prop. I think that I can be objective. My take as someone new to this airplane is that there is a significant difference between the two engines, especially during vertical maneuvers. Climb rate and speed are way better with the M14. With the Housai, the CJ is a docile, lovely aerobatic airplane that is a delight to fly, but I wish it had a better climb rate. The M14 I flew several weeks ago was a noticeably more powerful platform. When I can afford it, in several years I'll probably be hanging a M14.

The 50k you mention really isn't the cost of the upgrade. If you subtract what a housai engine would cost (18-20k), the cost of the upgrade is really only 25-30k. I don't think you'd be dispointed.

Undeniably the conversion will provide a significant increase in climb capability, but when you operate out of Petaluma at 87" MSL, this benefit is of marginal usefulness. >From a cruse speed perspective, most note a 5-10 kt increase, maybe more/maybe less. Assume a 10 kt increase - that's $5,000/kt increase, and if the new President's planned tax increase passes, you's need to earn and save about $8,000 for each increased knot. A good wax job and tune-up will probably give you a knot or two for substantially less! If supplemental stimulus or TARP funds are available, why not...if not?
