Red lining it...

Onne,

what sort of horses are those

They may not be many but they're BIG! Sure to be measured at the flywheel so you get as high a figure as possible. Thanks for advice (and to the Cam) MikeN.
PS first time I've done quotes. Thanks Relfy.

they don't measure them like that on modern cars do they?

Sturdy 48 bhp from the 1098 - 55 in the MG 1100 with bigger inlet valves, twin carbs and a surprisingly efficient 3 branch exhaust.
Always a really good idea to have a spare engine all ready to go. If there's problems with the one in the car - get started on the spares to see if either of them is any good. 1098 engine in the Minor/A40 was never given the crankshaft damper that the East-West engines had as standard. With a damper fitted they can be revved to 7k - but not for long. Life above 6k is fairly limited. Strangely the only cranks I broke were 948 ones - 3 of them - until I discovered the crankshaft damper.

Bmcecosse,
Does the crankshaft damper make the engine feel smoother? ( I ask 'cos elsewhere a thread runs on sound deadening, and it may assist on noise reduction at high revs.) If so, wot vehcle(s) should I look for to get one and it is a straight fit? No fan belt line-up problems? Regards, MikeN.

Straight off almost any Mini engine, certainly the 1275 ones, and also the 1098 E-W engine. I helps at high revs to 'kill' resonance in the crank - but for poodling about it won't make any difference.

Bmcecosse, Wot you mean by high revs?
I realise that 70mph at circa 4300rpm may be "poodling" that you, but its transonic to me! You put your finger on it - if they have the crankshaft damper on the later E-W 1098, should we as a precaution fit to the ealier N-S 1098? I'm trying to scaremonger, I just wonder if there would be a noticeable improvement. Perhaps the later engines have less crankshaft stiffness, or strange resonances, but I'd be surprised if it was so. Or does it just rev at higher? Regards, MikeN.

Basically if you are thrashing the engine fit one, if you are just driving steadily even at motorway speeds then don't bother. Of course if you have to take the pulley off for some reason then it would not hurt to fit one.

As CAM says - if you are going to thrash it then it NEEDS the damper. For up to 70 in top it won't make any difference. But for 70 in third it will help to hold it all together - and it seems to stop the timing chain flap about so much. But if you are going for a performance engine - you will be fitting duplex gears and chain anyway.
