I tried to use Cadmium/silver, when we were using the high oil pressure (60/80 lbs) but the bearings were flaking. Looked like they had chicken pox. Also the filit radius of the crank had a slice it it caused by cavation erosion. This was cleared up by increasing the side clearance and reducing the pressure to 40/50 lbs. The oil we used back then was Penzoil 40W . Track racing is much differant than drag or straightaway racing. the engine doesn't run long enough to build allot od bearing heat. Except when under Hi boost or nitro/nitros, Not sure how to keep one of them togher

This business of bearings is a long and frustration joinery . How do the NASCAR bearings stand up to 500 miles of FULL POWER runs?? I'm building an oil cooler for the roadster.
