My 2001 Firehawk has issues with the oil pressure
My oil pressure gage fluctuates.... It when I step on the gas.... If I step on it all the way I'm pretty sure it will max out and do damage.... The highest it's gone is 70 psi almost 75... I'm pretty sure it's not normal.... Can anyone help me out.... Oh yeah I forgot to mention it has a Vortec Supercharger
Re: My 2001 Firehawk has issues with the oil pressure
not sure you have a problem at all... how low does the oil pressure go at idle? Has anyone done any internal mods to the engine? As in changing out the oil pump?
Re: My 2001 Firehawk has issues with the oil pressure
Not sure if anyone replaced the oil pump.... I gotta look more into it I just got the car
Re: My 2001 Firehawk has issues with the oil pressure
I'm trying to find the previous owner to see what internal mods were done there's only 76,000 miles on the car
Re: My 2001 Firehawk has issues with the oil pressure
as long as the oil pressure does not go too low... you should be ok from the sounds of it. The old school rule of thumb is you should have 10psi for every 1k rpm. So yes, as your rpms increase, your oil pressure should too. I know on my built setup, idle is in the 30 to 40 psi range and goes to about as high as 80 or so from about 4k to 7k rpm.
Re: My 2001 Firehawk has issues with the oil pressure
Wait I was wrong it idles at about 50-55 psi.... When it's cold.... Then when the care warms up it idles at 40 psi
Re: My 2001 Firehawk has issues with the oil pressure
So going all the way to 80 doesn't mess up the car?

Sounds pretty normal to me.

Re: My 2001 Firehawk has issues with the oil pressure
The SC must be fed lubrication oil from the engine, so the cause of your unusual OP behavior may be related to whatever was done to plumb in that oil supply and/or the oil return. Can you find a set of instructions for that work?Maddripp wrote:Oh yeah I forgot to mention it has a Vortec Supercharger

I did a little searching on the net and it does sound like 80 psi could start causing some issues - filter gasket blowout, rear main leaking, stress on the oil pump shaft, etc.Maddripp wrote:fb_rider nothing happens to the to the engine If it goes to 80 psi?
It sounds like you need to learn some more about what was done to the engine - for example, was ther a higher pressure pump installed.
Also I'm assuming that you don't know what oil is in the car? I saw a couple of articles where putting a higher viscosity oil in an engine caused higher oil pressure, especially in cold weather.
Maybe you should start by changing your oil and see what that does.
Here is a pretty informative site http://www.bobistheoilguy.com

Thanks you guys.... I'm trying to find the last owner but I can't track the guy
Re: My 2001 Firehawk has issues with the oil pressure
I have no actual info on what exactly what was done to the car or why it's doing what it's doing
