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 :D 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

judgie was the crank damaged. Whats the reason for the regrind and polish.

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.
