It was one of those good-natured arguments in the pub .... which, so far, has been the UK's most powerful F1 engine of all time ?
I'm probably wrong, but I opted for Cosworth's turbocharged 1.5-litre vee-6 of 1987, which seems to have raced in Benettons with a reliable near-1,000bhp.
Now shoot me down or let's, at least, have some reasoned alternatives.
