Supercharger Kits - MGB

Supercharger Kits - MGB

Superchargers have been used on cars and piston engined aircraft since before World War II in order to obtain maximum power without losing vital torque. The Moss supercharger kits give increased torque and horsepower throughout the rev range without adding extra stress to your engine.

Our supercharger kits use an Eaton MP45 charger unit that features a by-pass valve. During light throttle conditions this valve remains closed by-passing the compressor, but then opens to feed the charge through the compressor to give maximum power when required. This system gives good drivability and maintains economy during light throttle conditions then boosts the charge the moment the throttle is pressed, giving an instant boost of power.

Our engineers designed an intake manifold that provides equal airflow, pressure and fuel mixture to each cylinder. By optimizing the distribution in the manifold for each cylinder, you can run more boost pressure without the chance of harmful detonation. The Moss supercharger system produces 7.5- 8.25 PSI of boost at sea level. Bolted on to a standard engine you may expect a horsepower increase of 40% at the flywheel. Just hold on to the steering wheel when you decide to press the pedal!

The kits include an MP45 supercharger, intake manifold and SU HS6 carburettor, alternator (1968 on models only), special pulleys and a serpentine drive belt, K&N sports filters, fittings and comprehensive fitting instructions.

To optimise the performance of a supercharger installation we offer a special high lift, short duration camshaft. This camshaft is only available new/outright.

To maximise the full benefit of the supercharger we recommend that you fit the 8° static advance distributor (TMG10771).

Please Note: These systems are designed to supplement an engine in good condition, not make up for lost power in a tired one. If your car has an old, tired engine you will need to overhaul it first.
