Built motor people I have a question

[1998silverbird]

What kind of oil pressure do you all have?? My mods are in my sig.. When I start the car up it idles at 60-65psi.. When I drive it around it is around 70psi and at W/O throttle its at 80-85psi.. Now the thing I am noticing is that when I drive around and come to a light, with the car sitting idleing at operating temp my oil pressure falls to 45-50psi.. I give it a little gas and it goes to 60-65psi but when the Rpms drop back down to 800rpms it goes back to 45-50 psi.. Is it that I am thinking about my motor being messed up to much, because 50psi is still good oil pressure at a idle or is there something wrong with this picture cause on my stock motor it never went below 60 psi.. I do have a pretty big cam and also a oil pressure booster washer.. [img]graemlins/popcorn.gif[/img]

45-50 psi at a warm idle is nothing to be alarmed about. As long as the pressure goes up as soon as the revs start to climb you shouldn't have any trouble.

I think mine is close to those numbers. So I would say it is normal.

my stock motor is almost identical to those numbers

Cool thanks for the replies.. I couldnt remember how my stock motors were so I was kinda getting worried..

Mine was doing the same thing, but I cleaned the pick-up screen when I changed out the oil pan gasket two weeks ago and it pretty much stays up around 70psi, up a little / down a little but doesn't drop that low any more. BUT, 50 still isn't an issue.

Try 30 PSI at idle and 45 at WOT...

and still no performance loss...

There might not be a performance loss, but is there a premature wear issue going on that you're not aware of. I'd be worried about not enough oil getting to the top of the motor at WOT.
