 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.
