Finally took it for a test drive today :-) very happy with the outcome, more power and Tourqe throughout the rev range. The engine is very smooth and not too noisy in the cab.
All the charging and vacuum system is working really well, the little vac pump on the alternator pulls more vacuum than the petrol e gone did and coped with the servo operation just fine. Cooling system works a treat, left it running for a few hours in the yard and the temperature never went above 85c , very happy.
More testing over the weekend. 😄
