2ltr dyno results
had the 2056cctype4 on the dyno yesterday and made a awsome 145bhp at 6900rpm at the rear wheels with 129ft lb of torque
 all this from a 30 year old push rod engine.biggest prob was on the last run the dry sump pump has broke a gear and sheared the drive so starveing the crank of oil, have got all the parts to sort this bar a 3 stage dry sump pump. anyone one know who makes pumps for the type 4 still? type 1 wont fit. cheers rob

big ends had been scored when the crank was starved of oil but no visable damage to the mains so just had them polished. so theres a freah service for the new shells to bed to.
cheers rob
