 For my part its because I'm stuck a statement by Jack Roush. paraphrased:
"It takes 5psi per 1000rpm to ensure enough oil is supplied to bearings to
ensure an adequate bearing film and cooling for the valve springs. At least
10psi per 1000 if that engine is used in Motorsport." I submit that Jack
Roush forgot more about internal combustion engines in the last 5 minutes
than you or I will ever know. After all the work he did making some of the
worst oiling engines ever built live through 1000 miles races he should know

 Bernie, I understand your flow vs pressure logic but I'm not willing to
accept oil pressure losses the way you seem to be.  With the tight clearances
in these engines pressure is required to have any flow. Given that the cams
dont use bearings the last thing I want is a pressure problem eating a head
and possibly breaking a cam, btdt. When these cars were new they showed a
certain amount of pressure, I want as close to that as I can get. My car
pushes nearly 5 bar just off idle when hot and running 5w30 synthetic.  That
tells me my pump and bearing clearances are still tight. If I see a drop in
pressure I wanna know why, immediately. A filter that causes me to lose
pressure is a defective filter, period. A  sensor that starts giving bad
readings needs to be replaced, period. An engine that cant hold a fair
percentage of its original oil pressure needs work, period.

 Now please explain something to the list......... How is it that you are
dead set against using a key in your door so you preserve $30 in potmetal,
and are so worried about a minuscule alignment problem that you design a
strut brace to correct it, but are apparently willing to ignore possible oil

Just curious,
