No one loves old Fords more than me, but I’m glad we don’t have to deal with this anymore LOL

Hi Adam,

In my opinion the worse motorboat sound was the old Thermactor Air Pumps.... On the 460 in the Econoline HD there were two of them, mounted on top of each other with a tiny V belt between them. Since they were three bladed vanes the pulses would beat against each other and create a very annoying whirring sound. I was an NVH Technical Expert at the time and was tossed this to solve. Rule of thumb was to separate noise generating devices by 10%, so I had a pulley made that slowed the top pump by 10% and it worked. Now the problem was that the air pumps were an emissions device so the whole darn process of recertifying was required and at that time was very time consuming....Good thing for HD vehicles it was just an engine on a dyno.... Once we got the rescertification...all was well and I received my "attaboy"...

best,
Phil
