Years ago I had a 4 cylinder Ford (Mk11 Cortina) that I tuned. It was very reliable but every time I took it for a long drive it would blow the alternator after about 50 miles. Drove me crazy. I fixed it permanently by bolting an thick aluminum plate to the block and then rubber mounted a similar block to this. The alternator was bolted to this. This eliminated the high frequency vibrations that kept destroying the electronics.The holy trinity is heat, vibration and RPM.
