is it bad to have too much oil press? i started to pay attention to my oil press gauge since ive been keeping up with the "should i really switch to GC/amsoil/royal purple/redline/walmart brand/anything but m1" threads. i havent noticed any "sewing machine noise", and ive never had oil consumption problems. it gets m1 full synth 10w-30 every 4k miles. i just noticed since ive been paying attention in the last week or so that my press guage reads 48-ish at idle, 2k rpms cruising reads around 60-ish, 4k rpms cruising reads around 73-ish, and on a hard pull all the way up the tach its nothing for it to peg the gauge...any thoughts? im just trying to make sure somethings not amiss before i have bigger problems...

thanks

Mine is kind of similar. I have around 40-50 when at idle, 60 just cruising, and at WOT it gets close to the 80 range.

Wish I had that problem. I cant get mine over 10psi at idle or about 25 -30 psi around 4k rpms

There is a point where you'd spin a bearing as the oil is moving too quickly past the bearings to lubricate them. But that point wouldn't be reached until well after 100psi. The 03/04 Cobra 4.6's run very high pressure, a little higher than your car. If a mechanical guage does indeed verify your high oil pressure readings, the clearances must be pretty tight. If it were my motor, I'd just run a regular 30wt synthetic like Mobil 1 5w30 year round.

Just for reference:

Cold start = 70-75psi
Warm = 60psi
Hot/cruise = 50-55 psi

Ported LS6 oil pump.

LS6 pump here...and for reference:

~60 psi - cold start
~40 psi - hot idle
~65 psi - WOT

Here are Oil articles by an MD/Biochemist/Car Guy that might change some peoples mind. 0W-30 for me.

Cold idle: just over 60 psi
Hot idle: just over 40 psi
70+ psi anywhere over 3000 rpms.

NastyTA easily pegs his oil pressure gauge too and he's running 7-800 hp with his turbo. I'd say you're quite fine.

the new LS4 oil pump is better then the ls6 ported or not and its only 60 bucks from fred beans...

75psi - cold start
55psi - hot hot idle
75psi - WOT
65psi - cruise anything over 1200rpm
