1098 quoted power output?

The quoted output for the 1098 Moggy seems to be 49BHP at 5100rpm.
The quoted output for my boys' Austin 1100 is 55 BHP at 5500rpm.
Same engine, carb, air filter, manifolds, similarly strangled exhaust.
Where did they find another 6 bhp from? Is there thicker carpet in the Moggy stopping the accelerator going right down??

Morris Minor 48 bhp - and Austin 1100 also 48 bhp! The 55 bhp was only for the twin carb/3 branch exhaust/12G295 headed engines- in the MG/Riley/Wolseley versions - was there a Wolseley - can't remember! If there was - it certainly just had the same size (and hopeless!) brakes as the others !

48bhp for the Minor and 1100 was my understanding. there was an MG 1100 with 55bhp. This had twin carbs and a larger valve head.

What a prat!! Looking at the wrong specs!!
Had me thinking the 940 head etc had been a bit of a waste and there was an easier way to get more power

Wolseley 1100/1300 was fitted with hopeless brakes?....discs of course

Yes - discs - but with small pads. Actually - it was generally the wheel bearings that let it all down - they were too small - and NOT taper-roller type, and the disc soon started to flap around - pushing the pads back and giving a very 'long' pedal.

This one has the "swing" calipers with tapered disc pads- never seen anything like it!! What on earth was in the mind of the designer?
Don't know about their efficiency, but the chap I bought it off had driven it home when he had collected it, and not noticed that it only had pads in the l/h side caliper!

The swinging calipers were a leter addition - but I don't think the pads should be tapered! They may wear like that - but I think they start out flat ?

Definitely tapered from new, straight out of the box!! 16mm to 10mm!
Unbelievable waste of material, apart from anything else!

Don't remember that - but many years ago since I worked on them!
