Hello,

Yesterday I vistited a more or less local tractor pulling event. There were several Merlin, Allison V-1710 and Griffon engined pullers, but also one powered by a huge Isotta-Fraschini 18 cylinder W-shaped engine. 72 valves and 57 litres!

Just wondering; does anyone know if this engine was used in a plane, if so, what type(s) or if not an aero-engine, what use did it have? I talked to the owner as short while, but he didn't have much background info either. Except that it weight so much alone that he had only 500kg left in his weight class to build the tractor from!

Any suggestions? Don't have a photo, sorry. http://ubbxforums.ubi.com/infopop/emoticons/icon_frown.gif

here is a link to an Italian sea plane with the engine you asked about.

In the picture, one of the 24 Savoia-Marchetti twin-hull S.55X seaplanes
with two Isotta-Fraschini 18 cylinder water-cooled engines each,
mounted fore and aft above the monoplane wing, which took off
form Orbetello (Tuscany) on July 1, 1933, landing in Chicago (navy Pier) on July 6 1933,
at the orders of Italo Balbo.

It might be one used on italian motor torpedo boats during ww2.

Sweden bought 4 boats from Italy with Isotta Fraschini IF 183 engines: 18W 57L 1150hp/2000 rpm 87 octane petrol, weight 1450 kg. The fuelconsumpion is listed as 250 grams per hp/hour. 125 hours between overhauls.

The later Supercharged IF 184 had 1500 hp at 2000 rpm.

Thanks for the info guys! I found it a very impressive looking engine, it also has that typical hard-to-describe Italian look and sound.

In this case, without an exhaust stack (just 18 dented L-shaped hollow pipes!) it really did SOUND! http://ubbxforums.ubi.com/infopop/emoticons/icon_biggrin.gif http://ubbxforums.ubi.com/infopop/emoticons/icon_wink.gif

Next time I'll go to a pulling event I'll try to get some video/sound footage to share on this board.
