Our intercooled supercharger conversion is compatible with a single carburetor or electronic fuel injection. ![]() Commute on the freeway in your Spridget or Moggy! Increased torque means you shift gears less often and can push a taller differential ratio. Standing-start acceleration is dramatically improved, as are passing and hill-climbing in top gear. Installing a supercharger and intercooler on a stock A-Series engine can increase horsepower 40% to 50%, without detonation or impacting your Spridget’s smooth idle and street manners. Here is a video clip of the engine bay at idle:īest of all, adding a supercharger and intercooler to your A-Series powered vehicle can be done for well under $3,000-a savings of $1,600 to $3,000! If you already run a single SU HIF44 carburetor and find a serviceable used supercharger at a ‘you pull it’ auto recycler, your cost may be closer to $2,500.īut that’s for an intercooled system featuring a vacuum-modulated bypass valve from the 2002 Mini Cooper S for improved economy, reduced wear on the supercharger and serpentine belt, and smooth throttle transitions.Ĭlick here to review the installation instructions, click here for FAQs, or continue reading for benefits and an overview of the project. As a result, the amount of boost these ‘draw-through’ systems can handle without harmful detonation and back-firing is quite limited.īut now, there's another option: the Creative Spridgets DIY intercooled and dynamically bypassed supercharger conversion for the 948, 10 A-series MG Midget, Austin Healey Sprite, and Morris Minor. Importantly, none of the above superchargers can be fitted with an intercooler. superchargingĪccording to Eaton’s website, “nlike turbocharging, Eaton superchargers provide instant throttle response and torque across the engine's entire powerband.” Also, superchargers do not require custom exhaust work or a dedicated oil feed line, and they do not raise temperatures under the bonnet like a turbocharger.īut until now, only three supercharger systems fit under the Spridget's sloping bonnet: the inefficient and increasingly rare Judson setup the Moss Motors Eaton-based kit, which costs $4,600, and the High Performance Products twin-screw offering, which begins at $6,000. impacts its street manners and fuel economy.Ī viable alternative is forced induction, via a turbocharger or supercharger. Also, modifying an A-Series engine to achieve 90 to 100 h.p. The venerable A-Series engine is the beating heart of some of Britain's most beloved automobiles, but achieving a meaningful increase in horsepower means dismantling the engine and spending serious money.
