I have been considering the 180hp 170B as a backcountry bird, but I recently saw several videos of a "210hp" 170B with the TSIO-360. It looked less than impressive. It made me think of this thread to see if there were any hard numbers on the short field capability.
Do you all think that a 170B with the 360 or IO360 with the Sportsman kit and VG's is capable of 500' at gross?
Yes, I can get 500' at gross, wth IO-360M1B, Sportsman, MT and 29's. (No VG's). But I'm guessing from your username that we're operating at very different DA's.
Then there's this:
The M1B is a new certified engine from Lycoming in 2002 and comes under new FAA rules that state that the engine has to put out 5% greater hp than published so it can maintain the rated hp thru it’s 2000 hr TBO. So it’s published hp is 180 but on the dyno it shows about 190hp.
You also have the option of roller tappets if you want them, and there are murmurings of a GW increase in development for the C170B/ IO-360M1B. I'm not holding my breath, but it would be a major consideration if it comes through.
Here is a video of another IO-360M1B 170B takeoff on floats.
