All,

My anecdotal track experience does not justify the extra quart of oil.  I should know, having mosquito-fogged the Pahrump track and not added oil all day, I was actual 1qt below full without problems ;-)

I instead use an oil accumulator and Gary Hall's fairly simple sheet-metal 10 Qt pan.  I also feed oil directly from the filter output to the rear of the engine, just to be sure the #5 rear main bearing and the oil gallery junction there are well fed.  The vertical-mount style from Moroso is only about $50, and add about another $25-50 for plumbing.  I have never had any bottom-end problems and have many track miles on Comp T/A R1s.

I actually worry that an extra quart would exacerbate problems by foaming the oil and introducing air into the pickup.

FWIW,
