C172 0-540 Conversion

[Jim Lynch]

Looking for information on Cessna 172 0-540 STC conversion. Has anyone ever seen one?

I think there's 3 different O-360 conversions, and a diesel, but I've never heard of a -540 conversion. You'd be out of fuel in about two and a half hours with standard tanks.

There was also a Franklin conversion, but last I heard, they were out of business.


Edit to add;

There's at least two different companies doing O-520/550 STC's for the C-182

at 50 gallons an hour, you'll be out of gas well before that.

I'd double check that figure.

Yes, you would be, fortunately the O-540 only burns a small fraction of that

Could a 172 handle the torque of a 540? Probably rip itself right off the firewall!

If it could work, it would climb like a homesick angel though. Love to see it

In the chieftains I used to fly we had turbocharged 540's with 350 HP and they would burn around 18 gallons/hour(each) at 65% power and 50 degrees rich of peak, not that you really wanted to know that.

Yea, but they don't burn that on departure before you lean for climb...$$$$

I'm kinda curious why you would do this. Climb performance would be craptacular... but you still gotta observe V speeds. I'm all about bolting big engines to small vehicles but this just seems like a waste. I did train in a c-152 about 12 years ago initially getting my PPL that had a 160hp 172 engine in it. That thing was fun....

A 152 with an O-360??? That sounds like alot of fun. Just curious, what's the most "Over-Engined" POS anyone has ever flown in here? And another question, anyone know if it was the Lockheed LodeStar that had the 2800's on it?
