Good afternoon all,
Can anyone share the performance charts for the 1978 P210? I only recently discovered that the 1978 P210 had geardoors, and the 1979 and later had them removed.

The T210M with the gear doors has a cruise speed of 190 KTAS at 76% power at 18,000 ft.
The T210N without the gear doors has a cruise speed of 182 KTAS at 76% power at 18,000 ft. Even allowing 2 KTAS for the extra 200 lb, that is a reasonable increase in speed.

Has anyone got a 1978 P210 still with gear doors, and does it get close to book speeds?

I have owned a 1979 and then later a 1978 P210 with about 900 hours between the two. The 78 had gear doors and I would say it was perhaps 3-5 knots faster than the 79.

There are a lot of other variables, especially the rigging of these planes, that in the end it will depend on the specific example you are looking at.

They are great planes!

I have a 1981 T210N (no gear doors). At 15,000, 30/2300, ROP I get 195 +/- 2-3kts. It beats book values. I usually don’t run it that hard though. I have heard from other owners that the gear doors only add around 3-4kts speed increase. I like the design sans gear doors for less complication in the hydraulics (less failure points for loss of fluid). The Uvalde gear doors only add delete mod removes the doors but retains the hydraulic components.

The gear doors on all the 210s, NA, T & P are good for + 6 -8 kts over sans doors.

I had a '76 NA that I called the "Wichita Bullet", no gear doors & no boots and it was fast, easily cruising @ 170K Tas and a great family hauler to boot!
