If you've picked up your copy of BEAST, you're already aware of Patrick Morgan's superb CAD illustrations. However, those are merely static representations. Patrick also provided animation of the valve train movement from the pushrod engine. It's incredibly difficult to make a pushrod valve system that is very low friction at high RPM while also remaining intact somehow for 500 miles! It was also a source of many early failures and a constant source of worry all the way to the finish line. (If you've read the book, you know the dramas of the needle rollers - which are seen in the animation...)
Here is a slo-mo look at the unique valvetrain of the Mercedes-Benz 500I.
As always, I recommed you check out the fine work of Patrick Morgan's company, Dawn Treader Performance. Click the link to see just some of the amazing and historical race cars his company owns, maintains or have restored. Some amazing machinery.
If you have not yet grabbed a copy of BEAST for your very own, order it direct from Octane Press, or fine locales such as Amazon.com. (As of today, May 12, Amazon has sold out - but more books are quickly on the way.)
