THE FUEL OF TESTING

The next set of the engines were now put through Land Rover’s full suite of test including a 900 hour test rig endurance trill running  flat out over a range of speed and loads, followed by a full stripdown for a detailed inspections of the effects.
In vehicle tests included an almost continuous 50,000 mile track test run at high speed, plus low temperature tests in the Arctic, high temperature tests at 50 degrees C in California Death Valley, and high altitude tests at 4000meters (13,000ft).
Inevitably, that led to further development and refinements. The head gave us the most grief in terms of stooping things cracking. It’s very complex casting on the Strom engine because the pushrod operated until injectors apply tremendous loads.
They also take up a lot of space, together with the fuel galleries. So it did develop cracks here and there. The chain drive and the camshaft that drives the injectors took a lot of development because it was so new.
