The SUPERDECK I system is ERL’s feature product.  The SUPERDECK I system replaces the stock cast iron sleeves, with Ductile Iron sleeves and strengthens the block with a fully machined billet aluminum deck support.  The Ductile Iron sleeves are proven in race engines to hold over 40 psi of boost.  The SUPERDECK I deck support constrains the  top of the sleeve in an open deck block to prevent head gasket failure from sleeve movement.  ERL machines a recess into the deck and around the sleeves that precisely matches the deck support.  The machining tolerance held in this operation is ±.002” to achieve a precise press fit.  The deck support is machined from aluminum because aluminum conducts heat 7 times better than ductile iron. The SUPERDECK I offers the cooling capacity of a stock engine (open deck block) with the strength of a racing engine (closed deck block).
