|ERL K24 Sleeved Blocks|
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).
