I have just been reading a book giving details on the Duesenberg Model J that was made in the US of A in the period 1928 to 1937, it featured many inovative engineering pieces that would not be out of place in many of todays supercars,
Ie straight 8 engine
Twin Cams chain driven
4 valves per cylinder
Crankshaft damping done by using mercury
Low compression 5.2:1
This engine made 320 BHP
If using the centrifugal Supercharger the Bhp went up to 375 BHP
You might all ask, "what has this got to do with Pprune Rotorheads" well the fantastic performance of that superb Gangster car was created by,
Lycoming. no wonder their engines are nearly Bullet Proof!
