On fuel burn, a good comparison is the Bonanza A36. It sports a Continental IO/550, 300hp engine, the same basic platform as the SR22. The newest A36s, with the Raytheon Special Edition engine, trues at 179 knots at 75% power. Most Bonanza owners like to fly at lower settings . . . 23 inches/2300 rpm. That’s where I fly my 1994 A36. It’s a nice quiet setting. With it, you get something like 153 kias and 166 ktas at 6,000 feet. Running rich, you suck 15 to 16 gallons per hour. Running lean, about 12 to 13.
The A36 max gross is 3650 poounds. The SR22 looks like it will max gross around, what, 3200 pounds? Both are clean designs — which is cleaner, I have no idea, a retracted A36 or an SR22 with straight legs.
The bottom line is that the SR22 should go maybe 5+ knots faster than the A36 on the same fuel flow or slightly less.
I couldn’t find anything about the SR22 on CD web site. Do any of you have any information on the specs/performance and prices or when this will be available, also converting a SR20 PO for a SR22. I am now concerned about Take off performance in our hot and humid weather around here. I was flying a TB200 XL this week and at 200 lbs below gross our climb rate was in the range of 750 ft/mn.with OAT of 34 C and high humidity and I think the Take Off distance of the TB is better than the cirrus.
Any way you slice it, the sr20 is a rather heavy plane for 200 hp to haul around. CD has done remarkably well to wring the kind of performance they do get out of a 2900 lb–soon to be 3050 or 3100 lb–airplane with only 200 hp. With tuned induction (I think?) and tuned exhaust the sr20’s engine probably delivers a larger portion of its “rated” hp than do other installations (Cardinal RG or Arrow for example) of 200 hp fuel-injected engines. Perhaps also some owners are having max rpm set to 2800 to capture an extra 10 hp?
Nonetheless it could certainly use an additional 25-30 hp, or perhaps a turbocharged 200 hp (diesel?) engine, to provide an extra performance margin for high/hot situations, not uncommon in the Western third of the U.S.
The 300 or 310 hp engine in the sr22 should make it a screamer, but watch out for those 16-18 gph fuel burns! Still, I have always been wryly amused by pilots who spend $180K+ on a new plane and then worry about an extra $2-3 per hour for fuel…:-)…Here’s to 75% power!
