Performance Head Build - Some Assembly Required
UNDER PRESSURE
Not too many home builders are willing-or able-to drop six-and-a-half bills on a full-fledged bench-top valvespring tester. Luckily, Powerhouse Products has a low-buck alternative. This mini spring tester is easy to use. Simply place a spring and the tester in a vice (as shown), then compress the spring to its installed height (or the height you're checking), as measured with calipers. The gauge will give you the spring pressure-in this case, 110 pounds. Nice. An inexpensive flange allows the tester to be used in a drill press.
