The Beast of Turin or the Fiat S76 - 28.5 Litre (this is not a typo! :D ), four cylinder, four valves per cylinder, overhead camshaft lunacy.

It is intended to run this wee car at the Goodwood Festival of Speed next year. Should be fun. :D
 
Quite. 28 liter in four cylinders, they must be the size of dustbins. And man, the sound... And the way it nearly keels over when it fires up. :D

I wonder what the torque in that thing is. ;)
 
And I really like the wooden firewall.

Still had no luck finding the tech specs of this thing - like bore and stroke. Mind you it's probably something nuts like several hands x a yard!

According to this article - somewhere around 2,000 lb ft!


Edit: Found it here - Bore 190 mm x stroke 250 mm, for a capacity of 7,088 cc per cylinder or 28.3 Litres for the engine.

Christ... That's over twice the bore of my GS and nearly four times the stroke. (And twice the cylinders.)
 
It seemed to start remarkably easily....no cranking over and over to draw mixture into the cylinders. Preumably it actually kicked into life when the ignition was switched on (Trembler coils?). I remember being told by a very old mechanic some 40 years ago that it was accepted practice to start some vintage-type Rolls Royces, when warm, by just moving the manual advance-retard lever on the steering-column to trigger a spark; no cranking, no poking about under the bonnet!
I believe that, in days of yore (!), it was thought that increasing the stroke was the best way to increase power, so some engines grew ridiculously tall...... some racing Peugeots had such tall engines that the driver had to peer round them....couldn't see over the top! Must have made for some interesting overtakes :eekicon:
 
Great stuff :thumbsup: :thumbsup:


Although he's holding the starting handle the wrong way -- shouldn't have his thumb wrapped round the handle in case of backfire.

Don't ask me how I know :D
 
It seemed to be in no hurry to fire anyway, looks like they had a bit of a trick cranking it into place and only adding spark when everyone was well clear.

Bit like hotbulb's roller, except that one would have some more cylinders so there would always be one in the right position.

Still. 28.5 liter fourbanger. That's bigger than a Spitfire, with a third of the pistons. Bonkers machine. I'm not even sure if I'd want to have a go in it, especially at the advertised speed.
