Anyone using a stock pan on their stroker with a high volume pump?

I went all last summer with the stock pan clearanced and a High volume Melling with no problems or drop in oil pressure at high rpms.

Also read a couple of articles on the net that say you can't run the motor dry but some people say otherwise.

I'll find the links.

 

I am still running the stock oil pan with my 383 stroker with no problems.

 

Me... stock pan, stock pump, 80psi spring.

George Baxter (1,125HP).... stock pan, stock pump, 80psi spring

John McMullen (975HP).... stock pan, stock pump, 80psi spring

Those are 3 examples I can think of.

 

The reason I ask is because I'm thinking of possibly getting a Canton Pan but I don't see my oil pressure drop at all at higher rpms.

 

Melling Hi-Vol Oil Pump

You do not want a high volume pump unless you also have a high volume oil pan. The stock pump is fine... get it blueprinted, tack weld the pickup, and use the "white" high pressure spring if you are planning on revving it over 6200rpm. A high volume pump on the stock pan will tend to run dry. There are 1000+HP LT1's running stock pump and pan.

Fred how many times have you heard this happen? I have this pump in my new motor and now i wanna cry. If i suck my pan dry on a 8k motor ill die. I have only heard this one other time. I asked at the machine shop about this and they said no way. Im reving 6600rpms maybe bring back down to 5800 and up the boost. can i put and milodon or canton oil pan with the motor in the car? room issues?


Fred i pulled this off the other thread.

Thanks bill

 

Same here No high volume pump, just heavy duty stocker

 

A lot of local engine guys say you will not run the oil pan dry because the sensors in the newer motors won't allow it to do so. They say it was an issue on carbed setups.

I'm not sure myself but I have a Melling High Volume pump with a massaged stock pan.

 

My pressure never drops but im worried now. The machinest did not even want to build unless i had a high vol. I trust him but fred sure knows his stuff and his opion is very trust worthy. What to do? If i can put a larger pan on with out jacking motor up i might just do it to be safe.

 

Yeah exactly.

My engine builder told me not to worry because he'd built them with stock pans before.

I just don't want to mess around with attaching the pickup to the pump.

Lots of people kill their motors when the pickup falls off. Thats my biggest fear of going to an aftermarket pan.

 

I have a melling HV pump with stock pan and my pressure drops at high rpm. I'm about sick of it, I don't even go full throttle anymore because of it, I can't afford a new motor.

 

Remember, not all oiling system are the same. Where the oil goes, based on clearances, and how fast it returns to the pan - restrictors, etc - will affect whether you have a problem or not. In all honesty, I have never personally seen the problem.. but I know it has been discussed at the shop that does my work, and I know there are people who have posted first hand experiences on Advanced Tech. If you have not had a problem, would appear your particular setup can live with it.

I do not agree that:

what sensors? The low oil sensor is wired to the idiot light, not the PCM. The low oil pressure light comes on at about 5psi???? And there is no input to the PCM from the sensor. Not sure what sensors you could be talking about.

 

Arg Camaro37 now im very worried, but have not had this problem yet. How many rpms or what rpm does it drop at? Like i said i m pushing 6600 and since rpms dont matter to me i might just drop them up the boost . I still dont like a possible time bomb though.

 

I have run a HV mellings on my 93 for about 6 years now witho0ut a problem. I didnt opt for the white spring that came with it. I also noticed that there are two different types of mellings HV pumps, one has a larger pick-up tube than the other but both have an HV before the part # on the body. Mine has the stock pick-up. I run 6 inch rods, ported heads the CC305 w 1.6s and 11:1 comp shift just past 6 and have no problems.
(Stock pan)
But on the other hand I have seen people have problems, dont know if i'm just lucky or if when I rebuilt my engine and I enlarged all my drain back holes it makes a big diff.

 

I've no clue what sensors either but thats what was said.

I'm wondering if it has to do with the weight of the oil as well.

I run 10W40 or 15W40 oil.

 

I run 10W 30.
