Well, I do need to start working on my oil cooler...
http://suzukisavage.com/cgi-bin/YaBB.pl?num=1247791900/0On cold start up, you got 50 psi of oil pressure, at idle believe it or not.
That dwindles away when hot. Why? cause aluminum expands faster than steel and the cam journals start flowing lots of oil.
But at 5k rpm, you still have 50psi and lot's of oil flow.
as far as a electric oil pump goes, you're gonna spend about $300 for a decent one. And the only time you need to run it is at idle.
