Audi V8 4.2 ltr petrol. Well spotted Trigger.
Fascinates me the complexity of it compared to the engines of the forum. Apologise for the thread drift though Julie's pictures inspired me to offer the comparison.
But also, for all its modern spec and development it has more or less the same BHP / litre figures in it's most potent setup as that 400 Four engine. Just shows how remarkable these little Hondas were when originally made.
I think they are a truly inspired piece of production engineering.
