I'm doing the very same Stoots IO-370 conversion to my '59 Cessna 175A. The maintenance team at KMNV just pulled it into the hangar to get started. Ordered everything a year ago, so stoked to see it get started!!!! Thank you for posting your videos.....just awesome!!
Kevin I’ve flown many Tailwheel aircraft and this 170 you have I want to check it out myself because it’s looks really fun to flying with more performance
Beautiful airplane! The 21st century flat panel displays are amazing. Any idea what penalty the big tires make on cruise speed and fuel consumption? I'm sure that the rough field capability is worth it, of course.
Thanks! Yes the new panel is way more useful. I don’t know truly how the big tires effect performance with the new engine, but with the old engine I went from 8.50s to the 29s and lost 5mph cruise speed. Yes they definitely help with rougher terrain.
We should be completing our upgrade and doing 1st flights later this week. Thanks for part 3. What speeds are you seeing with a fast cruise with everything pushed forward?
Nice that is awesome!!! Right now I have still been following the engine break-in procedure and backing it to 75% power. I know its got a lot more, I'll try to get some speeds, and that will be with the 29" ABW speed brakes on there too 😆🤣
Can you post a chart showing your real world performance numbers at cruise settings? Probably best would be at around 7,500 ft, showing IAS, rpm, mp, fuel consumtion when leaned correctly. I understand your big wheels may slow you down 3 to 5 knots so I can adjust accordingly. It is claimed 140 mph cruise is possible with this engine (small wheels). Can you achieve something close to this such as 135 mph TAS at a reasonable cruise setting at 7500 ft?
I can try to come up with some better numbers when I get a chance. I think that is definitely attainable, just not sure what the power setting fuel flow would be.
Those expand the cowl around the front two cylinders to allow the cylinders (rocker covers) to clear the cowling. The Continental IO-370 is based on the Lycoming O-360, which is a wider engine than the original O-300.
Yup you got it!! Not the same for all, but this fuel injected engine requires priming, then starting with mixture out, as soon as it fires mixture full in, to avoid flooding on start.
@@davidbrentfoster1 during a cold start turn the fuel pump on, mixture to full rich for 3-5secs, then mixture back to idle cutoff boost pump off, then start…. (Off for start) Boost pump may be needed/ used for ground ops after start but not required. So essentially just on for engine priming, then for takeoff.
I'm sitting at 1425lbs right now, it went up about 40lbs total with the conversion. The heavy treaded 29" bushwheels aren't helping things either, but still not bacd overall.
i am getting the same coversion done on my 1954 170b i also have a 1950 tha tis basically a show plane. this one is also very pretty custtom paint full glass panelw ith auto pilot. it is going to be my beater so to speak but ihav eowned both planes since 1980 i only paid for the 1950 21 grand and the 54 i paid 22 grand. both had been flying. when i bought them. so putting another 100 grand or so into the 54 is a good deal.
That’s awesome! Sounds like you are going to have too very fine airplanes! You are not going to be disappointed. While searching the 170 association forums I found a post from the previous owner of my 170 wishing they had more power, kinda cool to find he was thinking the same way!
Hello Kevin - Your airplane looks great. We are doing a rebuild on a 1953 170B that we just purchased and have a deposit in with Dave Stoots. Any chance you could send me your email or mobile so we can compare notes? Thanks
if you look to your left i will try to not remove your wings.if they endup missing do not blame me. at the very beginning of the video you look about 1 inch in the middle of the screen and ther eis something hiding in the woods staring at you

That’s awesome, you’re gonna love it, such a smooth powerful engine!
Great to see you are taking out that O-300 out of the 175 to a more powerful engine the IO-370
Kevin I’ve flown many Tailwheel aircraft and this 170 you have I want to check it out myself because it’s looks really fun to flying with more performance
Thanks! Yes I am still blown away at how well it performs after the engine and prop upgrade, the 170 does really well now!

Beauty. So hard to find one of these anymore that isn’t a fortune to buy or fix up.

Thank you, I loved this series! What's the range with the new engine?
Thanks! It’s over 4 hours but honestly we found that 3.5hrs was pushing it for bathroom breaks and a stretch! 😂🤣
@@KevinRudisill Haha good point! I thought the original tanks wouldn't be enough for the larger hungrier engine.
i am talking to the faa about maybe doing a field approval stc
what are the two protrusions on both sides of the engine cowling for
Those expand the cowl around the front two cylinders to allow the cylinders (rocker covers) to clear the cowling. The Continental IO-370 is based on the Lycoming O-360, which is a wider engine than the original O-300.
Is full mixture after the starter the book procedure for that engine?

@@KevinRudisill Do you have your fuel pump on during start, or do you prime, turn the pump off, then start?

@@KevinRudisill Awesome, thank you!! Keep you videos coming 👊
you missed bigfoot standing by the river. he was looking at you like LUNCH!
what is your approach speed and speed after flailing .
Any idea on your old vs new empty weight?

i do wish however i could stuff a 300hp in her lol make is a rocket ship lol
Haha! That would be sick!
