I would think about that.  YMMV. Might be a possibility, but I haven't consumed that Kool Aid....yet. Gamechangers that I have experienced: Garmin 430 30% or greater speed increases Air Conditioning Foreflight/Garmin Pilot coupled with a tablet Satellite weather and Satellite radio Probably not in that order....I would put A/C first

I think you are right Michael unless he is quoting a rate for an EMS helicopter operating off a platform in the Gulf

There is a huge barrier at 200 kts.... My Rocket is just over 200 kts... My Baron is just under it....
It really is a math problem.... So, lets look at it... Lets say you want to go 250 ktas...
Ok to do that at 10,000 ft you have to indicate ~208 knots.. That is a really big number...
If you are willing to fly at FL180, it gets much easier, 183 KIAS...
The next question is, what stall speed are you willing to accept? If you want to limit yourself to a 61 kt stall speed, then at 183 KIAS, you have 9 gs available at cruise and that is going to be an airplane that rides rough but acceptably in turbulence.... If you want to do that at 10,000 feet, at 208 KIAS (almost 12 Gs available) the ride would be unacceptable.... And you will need lots of power and a VERY small frontal area....
That means to get to a reasonable ride at 208 KIAS you need to raise the stall speed up to 75 KIAS Now you have an airplane that will cruise in excess of 200 KIAS and yield 240 KTAS at 10,000 feet and since it is supercharged it will maintain that power up to 18,000 feet where it will cruise around 275-280 KTAS... Sounds pretty cool right? Well it is because I have just described the P-51 Mustang.... To be strong enough to take that kind of flight loads it weighs 7000# empty with a 1500 hp engine and at 205 KIAS it burns 60 gallons per hour....
I spend lots of time in single engine airplanes with 75 KIAS stall speeds and highly stressed engines..... I DO NOT fly the IFR or at night, and most of the time, I am sitting on a parachute.....
I have a Rocket because 50 KIAS is what I believe to be a safe stall speed in an airplane that I can comfortably land on a road or in a field... It indicates 173 ish on 12.5 GPH and that will usually yield 205-206 KTAS but if there is turbulence, I have to slow down to 150ish KIAS or get shaken to death.... It is the maximum performance out there without raising the stall speed..... A TN System would be incredible in it!!!! But there just isn't room for it under the hood.....

Clearly you need a variable sweep wing on the Rocket (a la F-15) :-) Whenever I read about TN on Van's airplanes, I think about this write up: http://www.vansaircraft.com/pdf/hp_limts.pdf

If I TNed my Rocket, it would be very close to the TAS Vne at cruise... Aircraft design is one big compromise.....

My MU2 insurance (at $600K hull value) PLUS all my fuel for 125 hours/year (35,000 nm) adds up to about $40K. Mike C.
8% has to be a mistake.
If you figure the math, time value of money, deductible, casualty loss, etc, an 8% premium would pay for a new plane in 8 years.
I think twice about insurance for toys when it hits 1.5 to 2% of hull, which is paid for in about 20 years. If I was betting that I could have a hull loss every 20 years I'd give up on flying and take up boating.

Maybe the TN 550 Malibu would be just the ticket. David, The Malibu/Mirage is really a tight plane to get into. I'm 6 ft, 195# and too tight for me.

I'm roughly the same size, and I can get into and out of a PA46 with relative ease, but I'm very uncomfortable up front. For me, the seat won't go back far enough to let me stretch my legs out very far, so I end up with my knees around the yoke/control column. Doesn't take very long like that to become uncomfortable/stiff.

The later planes have a bigger cockpit. I am 6'2 and 200, and fit in my Meridian with ease. In fact, I actually bring the seat forward 1 click. There is a technique to get in position, but that is the same with many cabin class aircraft. Starting in the 2011 time frame Piper started making some interesting mods, the latest iteration have a couple of inches extra hip room, more headroom, and the seat back now rests behind the wing spar giving more leg room. So you would have no trouble in a late model PA46. Even in a standard PA46 6/195 should not be a tight fit. I wonder if the seats were set up right. Not only do they go back and forth, but they raise up and down, and recline. Really should be able to adjust that comfortably.

Malibu airspace has a seat mod for the earlier ones that adds head room and leg room. My 6'4" 230# friend fits just fine.
