The Triumph Super 9 was first introduced by the Triumph Motor Company in 1931 at a price of £185. It continued through into 1933. It had an RAC rating of 8.9 hp.
The Super 9‘s were the first Triumphs to use 12-volt electrics (early Southern Cross’s still used 6-volt for a short period) and the first to be fitted with a Coventry Climax engine, which was made under licence by Triumph. Two 6-volt batteries were housed under the rear passenger floor, while the prototype had a single 12-volt battery on the bulk head. Many of the chassis and transmission components were left overs from the Super 7’s and 8’s.
The Coventry Climax engines are of the IOE configuration, with a bore of 60 mm and a stroke of 90 mm, giving 1018 cc. Generally a Solex side-draught carburettor was fitted. During 1931 the rear of the engine was supported on a 3/16-inch steel plate spanning across the chassis, consequently the gearbox bell housing was deep and with the starter alongside. Later cars had a cast-iron flywheel housing and a much shallower bell housing, the starter was then repositioned alongside the engine. This arrangement was used on later Super 9s & 10’s and on Glorias. The cooling waster is circulated by thermal syphon aided by the sloping shape of the aluminium water manifold on the head. The dynamo is driven by a Duplex chain with the distributor mounted at the rear end of the dynamo. A top speed of 60 mph was obtainable with a cruising speed of 45 mph. Petrol consumption in the region of 35 mpg for a car weighing 19 cwt. unladen.
Steering is by worm and wheel, the drop shaft attached to the wheel is on three keyways so it can be turned through 120 deg. to compensate for wear. Also adjustment is provided for engagement of the worm to the wheel.
Transmission is through a single 8 1⁄4-inch clutch plate along with a 4-speed-and-reverse gear box. The hand brake operated a transmission brake attached to the rear end of the gear box. A conventional Hardy Spicer prop shaft connected it to the axle. The rear axle is a worm and wheel with underslung worm, making for a low floor. Ratios 5.25, 5.75, 6.25/1. The brakes are Lockheed hydraulic acting on 9 1⁄2-inch drums with one leading and one trailing shoe on all 4 wheels. The petrol tank is at the rear, unlike Super 7’s which had a gravity tank. Fuel was pumped either by Autovac or SU Petrolift.
