Wouldn't have even thought about it without energy saving devices the airplane was equipped with like GPS, nice autopilot, and the rest during the final fuel stop. That and only the last leg was IFR..
Below is a comment sent on the Mooney mail list with regards to speed mods but it addresses the issue you raise about energy saving devices:
N9208M has no speed mods, per se. It does have the oil cooler relocation mode that I think reduces cooling drag, and certainly helps in keeping the engine cool.
It obviously has the Monroy long range tank STC, that adds 36 gallons to the normal 52 gallons. This may be the best "speed mod" because it can eliminate the necessity for en route fuel stops and extra climb and descents.
There is the issue, also, about other upgrades that made a 13-hour flight feasible and reasonable comfortable. Foremost among this is an autopilot with altitude hold that basically allows the pilot to sit back and monitor the flight rather than hand-flying it all the way. I have an Stec 30 with altitude hold.
Second is a smart GPS that makes navigation "automatic" in that the entire route can be entered and, once again, the pilot only has to monitor progress and note the time-to-destination readout. I have a Garmin 430W.
Third is a fuel totalizer. This is, in my opinion, an essential item. It allows accurate fuel management to the 1/10 of a gallon and is an invaluable tool for leaning the engine to for the ultimate efficiency. I have a JPI 450 which is also linked to the GPS showing fuel requirements to destination.
Fourth, is an all-points EGT or engine monitor. This is necessary, along with the fuel totalizer for accurate leaning of the engine.
Fifth, is in flight weather monitoring. I have a portable Garmin 695 with XM weather mounted on the pilot side yoke. This can portray Nexrad weather ahead, forecasted winds aloft, and destination weather. Also, it can do a dozen other useful functions including receiving XM radio (I don't use the latter function).
