Hi Dan,

Thanks for asking about my trip to Sun N Fun.  First, let me offer a
disclaimer that I am an investor in Engine Power Systems.

I flew my IV-P to Sun N Fun with the EngineAir V-8 powerplant.  The engine
ran flawlessly.  Push the throttle forward and the computers and wastegate
take care of the rest.  I averaged 250 knots true airspeed at 15,000 feet
burning about 19 gallons per hour (65% power, economy cruise).  I am using
the new AeroComposites three blade propeller and I believe it outperforms
the MT I had used previously.  Performance at 22,000 feet is much better
with true airspeeds of 290-300 knots at 65% power buring 18 gallons per
hour.  If someone wanted to go faster, they could do so by increasing power
and fuel burn.  At 300 knots, why bother?  I do indeed have the early
engine version that is 375 cubic inch and 420 HP.  The new engines, more
than twelve of which have been delivered to customers, are 400 cubic inch
and 440 HP.

As an aside, I can burn 93 octane which saves me $100 every time I fill up
with autogas.
