I was wondering what is the best engine for maximum speed?

I think Malcolm Campbell proved a big **** jet turbine was the go. Maybe 25000 shaft horse power would do it, maybe a GE LM2500 then.

But whats the context?

for a roundie dumbo - do you think that makes a difference given that they are more aerodynamic than those bluff fronted ones?

Must be some drag coefficient calculations out there somewhere...
Beyond that, I suppose there's no substitute for cubic inches.

There's not much difference in drag between a roundy and the `Ford fronted' ones. They are both pretty poor CV, but better than a Moke (with or without the tent erected).

I would think a Mk 1 or Mk 2 1275 engine. I did read as a bog standard item they'd reach 100mph or just under.

but not all 1275 are created equal. Would a tuned 1100 beat a boggo 1275?

I feel that a supercharged 1098 would beat a stock standard 1275, but thats assuming the block has in fact been painted red to make it go faster.

What do you base that on? Wouldnt a blown 998 be better than an 1100?

I had my std cooper s upto 115 mph once, it said so on the speedo and can be backed up by the fact that this story is now on the internet, and therefore must be true

must have been a big cliff

you could blow all four piston rings like i did taking the speedo off the dial, bouncy bouncy i dont want to go any further, the needle said to the car.

A couple of little stories from the 70's. I was in the National Service at the time, I had a 997 Cooper that I had modified quite a bit, it had an 1100cc block with a worked head, Wade 140 cam, weber and a few other bits, I thought it was very quick until another Nasho said come for a ride in my 1275 Cooper S, it was brand new, about a month old, at the time I could not beleive how quick it was, I was shell shocked, within 2 weeks I had traded the Cooper on a new Cooper S. The fact it was a brand new car I think made a big difference it was so much faster than my 1100.
That same car was a very very good example we compared it to my then new S and his was always that little bit better all round in performance.

As to top speed, back before the hume freeway was built in Victoria there was a big hill called 'Pretty Sally' near Seymour, we had 4 Nasho's on board the S and he wound it off the clock going down this long long hill, I remember the needle wound right past the 120mph mark, it was down hill though. His was a very good stock S though and he could readily pull 100 even on a flat ground but there was nothing much left in it.

By the way there were no speed limits then!

Back in 1969 (no fixed open road limit in NSW then) a Mk2 Police Cooper S was good for 106MPH, downhill. So said Mr Plod when I slowed down for a town, and he finally caught up.

My problem is by the time you have hit 100mph you have done half a lap of the island.
