The Serck cooler to WS.6027 in my opinion is too restricted for water flow, the inlet and outlet being about .750 dia. where as we should expect to fit a pipe of about 1 1/4 dia. since the cooler is on the suction side of the water pump. Your preliminary tests will prove the point. HEADER INTERCOOLER SERCK OIL COOLER Jnr.{Charles L. Jenner} | ||
