Getting ready to fire up a 408 with the slp oil pump and I'm wondering what oil pressure I should have.

Thanks Raul

Should be 40-42psi @ idle and 60-65psi @ WOT.

Anybody else,Im running around 35 at idle I want to make sure I have enough oil pressure.

35 at idle is fine. What weight of oil and did you use the high pressure spring?

maybe i got a different pump then everone else... but when i did mine it came with 3 springs for pressures so it depends on which one you run i have about 40 at idle and 60 WOT

I never opened the oil pump or remember what it looked like.Because I bought it several years ago and had a friend install it.So there's different springs that it came with for different oil pressures.

I'm running castrol non synthetic 10w 30 right because it's a new motor and in the process of breaking it in.

yeah well i put one in yesterday and it has 30 warm idle and 40 off idle WTF i am pissed about to pull the cover off and check the o ring which i do not think i installed wrong

Yeah that sounds exactly like my situation on my 408.I bought my oil pump over 4 years ago I'm wondering if I just got the first cheap design.I think I'm just going to pull it out and get the TSP one.I invested to much money in this motor to let an old design oil pump break it down.

thats ok i just bought it last week from summit took my ls6 pump out and thought i was upgrading it

My brother has the TSP one and his oil pressure is way higher than ours.That's what I'm going to get before I start hammering it.

60 on a cold start
48 at idle
80+ on wot

I don't understand why you guys are stuck on needing higher oil psi? My understanding is 40psi @ idle, 60psi @ wot is plenty.

I'm not even 40 psi when cold.

The SLP pump comes with an additional spring for higher pressure.
