Subject: [TPR] Grooved Main Bearings

 O.K. guys there is a reason why nobody makes a fully grooved bearing but that 
takes in to play,bearing speed,surface diameter,surface width,R.P.M. as well as 
centrifical forces . Federal Mogul makes a 3/4 groove main for performance 
applications . You see every time an internal combustion engine fires 
it actually bends the crank,not much have you but it does happen ! The downward 
force that is applied as the spark plug fires is how a engine is rated as far as 
Horsepower & Torque (so to speek) That is also the reason why the rod bearing as 
well as the main bearing is not grooved fully ! It requires that added bearing 
surface to put up with the load .It actually has very little to do with 
lubrication .There are a ton of other factors that come into play here but that 
is the general idea .
