Hey PorkChops. I'm talkin' to you.

[Slick Goodlin]

That’s a lot more airplane than I want but what a machine!

[Colonel]

I wanna know what Juan Browne paid for that 1959 C310 …. I’m guessing peanuts, from some old guy.

[Big Pistons Forever]

Buying an old airplane is the cheap part. Getting it running and keeping it airworthy is when you start spending serious coin…..

[digits]

Ah, only an S1C... That means it should be cheap....


Not sure if it is impressive or scary they are getting 248 HP out of a lycoming 360....

[Colonel]

782 pounds and 248 hp. You do the arithmetic.

I was intruiged that he got that power at only 2700 RPM.

One must wonder what his BMEP is. And how much power it makes at 3300 RPM!

Recall that a stock TCM GTSIO-520 runs 3400 RPM every takeoff with 3/2 prop ratio.

A friend of mine tried running a turbo on his 4 cylinder Pitts. It didn't last long - I presume
the bearings weren't happy with the precession. The Pitts didn't last long, either - anyone
remember the Ottawa airshow in Carp in the late 80's?

[Colonel]

Interesting comparison.

Certified TCM GTSIO-520-K puts out 435hp or 435/520= 0.84 hp per cubic inch

Hotrod Lyc 360 on the brink of destruction puts out 248hp or 248/360= 0.69 hp per cubic inch

Generally the smaller engine puts out more hp/cubic inch

So what you are saying is that they could go for even MORE POWER

[Colonel]

Well … if the Lycoming 360 made the same power per cubic inch as the Continental it would be over 300hp.

Just sayin’ … the cylinders are roughly similar dimensions… about 90 cubic inches per jug, and I’m guessing rhe bore and stroke and combustion chamber are similar.

With the same BMEP and the same RPM, volumetric efficiency might be the only big variable.
