You're right of course - I should have clarified my earlier statement. I was thinking A36 with rear seats removed, so comparing a 4 seat configured A36 with the 4 seat Evo. I haven't had the 5 and 6 seats in mine since I've owned it so that's my mental picture of the A36 baggage.
There aren't many planes that have more baggage space if you've removed the rear two seats, lol.

I have never felt an airplane accelerate like that on takeoff and climb. We only used 40% torque for takeoff but it pulled like crazy. Once airborne we pushed the power in and had a 4500 ft/min climb indicating 170kts! By the time we reached our final of 17,500 we were climbing at 3500 ft/min indicating 160kts so needless to say it didn't take us long to get to altitude! At 17,500 we were able to push it to 293 ktas (220 KIAS which is the Vmo). I cannot wait to see what it will do in the flight levels. That's incredible. What's the full fuel endurance on the Evo?

Well, my Evo for instance will hold roughly 195 gallons (won't know exact numbers for a while yet). Climb is very fast so I'd say roughly 15 gallons is more than enough to account for taxi and climb (A spreadsheet I created actually said the Evo would only use 8 gal in climb but I wanted to account for taxi fuel use as well). Fast cruise would be about 42gph @ 305 KTAS. So that would give you about 4 hours and 20 min till E. 4.28h * 305ktas = 1,305nm + whatever distance you traveled during climb. Let's estimate it takes 10 min to climb to altitude at an average of 200ktas. That means you travel roughly 33nm in climb so you'd have an absolute range of roughly 1,340 nm. Not what someone would actually do, but not bad for high speed cruise.

i have the -135 and the fuel capacity is 164 gallons, at 28k my settings are such that i use 28 gallons/hr and usually it takes 12 gallons to get to altitude, so the range (proven) is 5 hrs and and 25 minutes usually at 270 kts gives about 1350 n/m. with some reserve.

Yeah I'm adding in a rear baggage tank. Biggest reason why I don't know what the total capacity will be yet is because it varies. I did my calculations based on high speed cruise (max power). If I were to pull the power back I would have similar fuel flow and cruise but just with more fuel capacity.
12 gallons to get to altitude is probably about right. I estimated 15 simply because it can vary how long taxi may take. For instance I fly out of Denton TX sometimes and I've been held on the ground for 15 min before waiting to take off.

That's a bigger issue for you, 4 blade and 78% idle RPM. For me, I idle around 17 GPH per engine, 34 GPH total, so significantly less. The 3 blade prop and 65% idle make a big difference. As for efficiency, ground idle is always 0% efficient. No useful work being done! Mike C.
