double grooved oil bearings on crank:
I'm building a new motor soon and im doing some research. Has anyone used the two grooved halfs of the bearings so that their is more oil being tossed on the crank? So you would buy 2 sets of bearings but only use 1 half of each set.

Re: double grooved oil bearings on crank:
I know having the bearings flipped around can cause "oil starvation" on the load bearing side of the journals. In theory you'd get more oil flow all around the journal... but, do you need it and is your oil pump stout enough to keep up with the extra flow/loss of pressure that style bearing would lead to?

I think the problem is actually something to do with oil starvation while cornering, so ill put a nice crank scraper on as well as a windage tray. If i have the money m aybe an accusump.
