One thing that I was surprised while at Roush is that take all the new Eaton blowers and put them on a shelf before they change to the Roush housing. There must have been 100 sitting there but they actually mix and match parts - blue printing to get them right. Then they run them on the test fixture to 16K rpms for 10-30 secs with all kinds of sensors hooked up. Then they run it again at a more normal speed. Don't know what Eldebrok does but it would make sense. Wish I had taken pictures of that while there.
