My Railton has a girotor style oil pump (actually from an old Mini-Cooper) mounted on the front cover and driven by the nose of the cam. It draws out of the standard Hudson pick up and pan and pressures oil through a remote full flow oil filter into an oil cooler mounted under the radiator and back into the motor from a log manifold parallel to the oil pan that has nine 3/16" tubes feeding through fittings in the side of the sump at each rod position and into the timing gear case. The oil pan is post war deeper style and the dipper tray is late step down configuration, that is high oil level. The little tubes enter through the wall of the sump and go into and are stayed in holes drilled in the dipper tray pieces that were designed to "catch" the oil slung up by the rod splashing through the puddle at bottom dead center. The whole point of this is to insure oil supply at each rod position all the time, to filter, and to cool the oil which is heated tremendously by the splashing at high revs regardless of cornering forces created sliding around the race track. I generally have observed the oil and water temps to run about the same (190 degrees) at the end of a 1/2 hour sprint.



This was brought on by a rod bearing failure the first time I raced the car, my reading of the history books about Hudson's rod bearing failures with the then new 8 cylinder at Indianapolis, and Australian Frank Kleinigs very fast Hudson 8 powered racer which had similar modifications.



Hope that's sort of clear--ask if not.

Attached are four images--I'm afraid they are too small. If you can't see what you want . let me know and I'll try to make them larger.
