 Riley M.P.H.

The Riley MPH is a rare, two-seat sports car made between 1934 and 1935.  The chassis used  half-elliptic springs and rigid axles front and rear, was based on  the car prepared for the 1933 TT races.  Side members were positioned under the axle at the rear to keep the height down to as low as possible and the centre of gravity.  Large, fifteen-inch drum brakes were used.

The  bodywork was mainly aluminium  over a traditional wood frame with an aero  windscreen that could fold flat to reduce air resistance.  Three sizes of the six-cylinder engine was offered, 1458 cc, 1633 cc or 1726 cc  all fitted with triple or more usually twin SU carburettors. Engines had the traditional  arrangement of twin camshafts mounted high in the crankcase and aluminium alloy connecting rods. The 1726 engine had an output of 56.8 PS   at 4800 rpm. Drive was  rear wheel through a choice of either  four-speed manual "crash" gear box or the ENV pre-selector gearbox supplied by Armstrong Siddeley. Top speed of the 17 hp (1726 cc) engined version was approximately 90 mph. Exact numbers made is not known ( bomb on factory records in WW2), but is believed to be 15 or  16, being expensive at £550 new. Numerous replicas have, however, been constructed fourteen original cars are thought to survive so if offered an 'original one' buy a lottery ticket then check with the club before opening the wallet.

*Not to be confused with the Vincent MPH a modern 'replica' made without harming any real Riley's*

MPH  Historic Replicas  ie using original parts and of some age:-

CPE 695 . A well executed replica of the Riley MPH.  Built about 30 years ago by the late Ivor Halbert using his genuine MPH ('JH 9506') as a guide, it is based on an original 44T chassis and still carries its original six cylinder 15T engine and its original registration number.

Info from Brightwells:-Ivor Halbert 1916 - 2009  Born in 1916, Ivor Halbert was brought up in an engineering family and was fascinated by machinery from a very early age – especially cars, motorbikes and aeroplanes. Already proficient at making things on a lathe while still a boy, he began his engineering apprenticeship at the age of 16 at Llewellyn Gears in making gears, airscrew hubs and splined shafts for aero engines and tanks.

After the war he went to work for the Bristol Aeroplane Company and by the early 1950s had acquired his own engineering business, GV Linham Ltd (named in memory of a friend and fellow engineering apprentice who had died in tragic circumstances). Operating from a purpose-built factory in Fishponds and employing some 75 staff, Ivor specialized in making precision components for prototypes and development models in the aviation and automotive sectors. His clients included Bristol Cars, Jaguar, Rotol, BAC, Rolls-Royce, Concorde and the Admiralty, all of whom demanded the very highest standards of engineering excellence.

Ivor’s real enthusiasm in life always centered around sports cars and he was soon earning enough money to indulge this to the full, owning a whole string of supercars from the likes of Ferrari, Lamborghini, Maserati and Porsche. Perfectionist that he was, he was always striving to improve the performance of these already impressive machines and he struck up a very close relationship with supercar dealer and motorsport enthusiasts Dick and Peter Lovett, buying many cars from their dealerships, improving them as he saw fit and helping them to tune and modify cars for use in competition.
However, Ivor’s abiding passion was for the Riley marque – he had learned to drive in a 1930 Riley Monaco that belonged to his father and was instrumental in persuading the family to buy ever more exotic Rileys that he would invariably modify and tune to extract every last ounce of performance. Italian supercars would come and go but, as time went on, Ivor became ever more attached to his Rileys (and the odd MG, Frazer-Nash and motorcyle), eventually owning the superb collection that you see today. It is only because of his death earlier this year, at the ripe old age of 92, that they have come onto the market at all. Also interviewed here

MOTOR DICTA By H. E. SYMONS. LESSONS OF LE MANS.

That astonishing Anglo French contest, the Le Mans twenty-four hour race, this year provided an unprecedented series of British successes. Not for the first time, an English car won the Rudge-Whitworth Cup-- the victory this year going to a couple of French men in a six-cylinder Riley-- while sixteen out of the twenty-three cars which finished were British-made. The Riley success stands alone. Six cars started, six finished. They all qualified to run in next year's final of this year's eliminating race. Never in the stirring story of Le Mans has such an achieve ment previously been recorded. When you come to think of it, the Rileys were really marvellous. The two which finished second and third, in regard to sheer speed, were only beaten by a super charged, eight-cylinder Alfa-Romeo of nearly double the engine size and three or four times the price. They properly saw off three other blown Alfas, a huge 4.9-litre supercharged Bugatti, and an assortment of other fast cars. The Rileys, of course, are not supercharged, and they have six-cylinder engines without overhead camshafts. How did they do it How do they get the stamina to withstand twenty-four hours of gruelling road-racing without the slightest sign of tiring The answer lies, I think, in the P.R." head, a cylinder-top in which the overhead valves are arranged in the same way as in a racing-car engine, with two overhead camshafts and a hemispherical combustion space. On the Riley, however, the drive is sim plified, and dead weight is saved by housing the camshafts one on each side of the crank case and operating the valves through push -rods and rockers. The excellent design of the cylinder-head enables a high compression ratio to be used with out pinking," while the engine is tuned to develop its maximum power at a very high rate of revo lutions. Rileys have considerably lightened their chassis and bodies, so that the new Imp model, on which Miss Champneys put up the best performance of any woman in the race, weighs under 14 cwt. A very fine power- weight ratio is thus obtained, and full use is made of it by providing a Wilson-type self-changing gear, by which instantaneous changes-up are always possible. The brakes, adjustable from the driving seat, are of large diameter, and the road-holding and cornering of the car are beyond reproach. The 1100-c.c. and 1500-c.c. Rileys were lapping the Le Mans course at such high speeds that they excelled the performances put up a few years ago by cars such as the 3-litre and 4 ½-litre Bentleys Sebilleau and Delaroche, on their Riley Twelve," covered 2706 kilometres in the twenty-four hours. In 1928, Babe Barnato and Bernard Rubin covered 2669 kilometres on a 4½-litre Bentley. This shows the progress that has been made in motor-car design in the last six years Even if it be true that the course is faster and easier than it was (which I am inclined to doubt), when the engine sizes of the two cars are taken into account the comparison is, I think, quite fair. As a matter of fact, the biennial cups have only four times been won at higher speeds than that which the Riley averaged so easily. The victors on two occasions were 6 ½-litre Bentleys, while on the other two, supercharged Alfa-Romeos of 2.3-litres capacity took the palm. Before leaving the subject of the Rileys I should like to mention that Miss Dorothy Champneys and Mrs. Petre, who finished thirteenth in the race as a whole, fourth in their class, and were the leading feminine team at the finish, drove Miss Champneys' own Riley Imp," with which she recently won the Ladies' Prize in the Scottish Rally a machine, therefore, that is obviously suitable tor all purposes. Lord de Clifford's car, with which he put up an excellent per formance and qualified for next year's final, was a Rapier Special, I as turned out by Dobson and de Clifford, Ltd., of Staines. Fundamentally a Lagonda, it has a special engine of under 1 100 c.c. (the standard job is just over this mark), and other features which make it eminently suitable for competition work. It averaged over 57 m.p.h., including all stops, for the twenty-four hours. The best performance on formula (which gives the right to try for an award in the final next year) was put up by Roy Eccles's M.G. Magnette," while Aston-Martins and Singers were serious rivals from The Sketch - Wednesday 27 June 1934
