Cubic Inches Are The Way To Go....Here Is A 1729 Cube Racing Engine

This is the famous S.76 Fiat racing car being built about 1910 above and finished below.

This monster had a bore and stroke of very close to 7 1/2″ x 9 27/32″

That 1729 c.i. total or 432 c.i. per cylinder which is bigger than most big V-8 engines in total. All of the details are at TheOldMotor.com

 

Holy Moley.......That is unbielable, I wonder how they started that monster??

 

Thanks again, Dave, there's a lot of really interesting on the oldmotor.com, the motor people back in the early days were just plain crazy, imagine what huge weight rests on the spokes of the wheels! this thing is (by engine volume) 14 times my daily driver!! maybe if i grow me a moustache i'll be as fearless as these guys?

keep on, nice stuff! thanks, Carsten

 

an army of midgets and a big pry bar.

 

At least they have a guard on the chain...

 

WOW WOW WOW....Just like everything you ever post here I WANT one!!

 

You can never have too many Cubic Inches or too much money.
It just really hard having both.

 

whats the output? 150hp?

 

Glad you guys are enjoying this Monster. As to starting it does have a crank and may have had some form of compression relief. It was probably primed with gas on the crank and touched of by a spark coil.

As to output 290-300 H.P. is quoted by different sources.

As we speak one is being reconstructed in the UK from a racing engine from Fiat and remaining parts from the two racing cars that were evidently built.

Can't wait to see it. Go to this link and scroll down a bit to see it. on both pages 1 & 2

 

I bet that car weighs two tons? And, running on little 1910 wheels and rubber. Crazy

 

I wonder what it sounded like. I'd sure like to know.

 

That was the dirigible motor, right? One can easily envision that thing powering an old railcar.

How do you say "Nipple-high center of gravity" in Italian?

 

In this case I suspect that the torques would be more impressive that the horse powers.

 

Thats insane. Im more amazed that wimpy side mounted chain could handle ALL that torque. 131 mph in those days was something dreams were made of.

For starting, it had a decompression cam, much like other ultra large displacement engines of the 1940s and older.

 

Imagine pulling into the LARS in that thing.

 

Literally: capezzolo alto centro di gravità

 

Wow!!!

 

I got a video of what a 1310 c.i. four banger sounds like. The Blitzen Benz at the Miller Meet. The pocket camera can't capture the true thump of the exhaust though.
