Mr Joe, although it is unfortunate that you sometimes have to represent your employees, but one of your sales staff certainly did tell me in person that the D would not pressurize the plane. It was less than a year ago, and in fact that conflicting remark as well as it seemed that he took additional time to critisize the Diemech engine,, has made me delay the decision about the engine. If you don't want to be thought of as disingenious, I suggest you have a sales staff meeting and get everyone on the same page. When someone you employ speaks, certainly on issues such as this, the guidance must be coming from somewhere. On the other hand, your statement about "high temperatures" from the flow pack is WRONG. On this issue, I have some knowledge first hand. Flowpacks are used by manufactures because they don't want to bleed too much air from the turbine. You take just a small amount of bleed and a bunch of colder outside
air, run it all though an intercooler and you have air that is not hot at all, and even better, the engine has plenty air left for power. Your EXE engine on the other hand, is pulling plenty of air from the turbine, (and yes,, this air is high temp) and my guess is that you have to run it through an intercooler (so much for your statement about cooler air),,, So, as you say, it is difficult and more expensive,,,, hmmmm.... I am quite certain now, that any of the EXE planes will be plenty slower than the D planes, just because of this issue. I have spoken to more than 4 EXE owners now, and I can tell you,, that the owners report poor to very poor support from Walter. Most of their problems seem to be installation issues and Walter does not support that..... According to a professional builder in the mid west,,, quote "there is nobody to go to for help". He was installing an EXE engine.
One other builder I spoke to, used a FACTORY LANCAIR test pilot for his EXE powered plane, and YOUR pilot overtemped and oversped his engine. (I wonder how much support Walter is going to give for that). The TSLM clearly showed what the pilot did, and he is now afraid to fly the plane. How can he trust the engine? Lancair doesn't want to replace the engine, Walter doesn't want to replace it... Let me ask you this, since you were the one that brought up the issue of support,,,, Would you want to fly in this plane after you knew it was overtemped and oversped??? How do you think your customer feels???? D

There are a lot of differences that would make one Lancair faster
than
another. Sometimes it is the weight, sometimes it is the addition of de-ice
and sometimes it is weather conditions. True airspeed should be close with
either the "E" or "D" engines. I cannot speak to Mr. Cooke's aircraft as I
have never seen it.
If someone at Lancair told you that you could not pressurize your aircraft
with a "D" engine, they would be incorrect. It is just a good deal more
difficult and expensive as you would need a "flow-pack" to reduce the
exceedingly high temperatures that will come from the high pressure/low volume
air that the "D" engine produces from its bleed port.
Your comments about my being a liar are truly disturbing and unappreciated.
If you wish to buy a "D" engine from Diemach or anyone else, that is your
decision. If you wish to buy a factory remanufactured engine supported by
Walter at a discounted OEM price, ("D" or "E") your option is then limited to
purchasing it through
us.
