oem oil pump?

[j dawes]

i just bought a motor [87 GT] to put in a future [fingers crossed] CMC car. i plan to 'go through it' and install some new parts for reliability's sake. i looked at the rules concerning oil pumps and didn'd see anything, so i'm assuming the OEM one is the only one allowed [if not in rules, assume not allowed].

 

plus, one that flows 25% more may not make that much difference, right? just asking cause it's basically the same price at partsamerica as the OEM one.

 

thanks!

Ok,

DO NOT put in a high volume pump,stick with a stock one or oem replacement.

I'm not only saying this because of the rules but the HV pumps pump too much oil which causes problems.

Jon you might want to read the rules once or ten times more

8.18 Oil Filters and lines may be replaced or added. Dry sump lubrication systems are prohibited. Any oil pump that fits in the OEM location is allowed.

I'm in the process of going through my future motor as well. Mine is a 25K stocker I found from a kid that swaped a 351 stroker in his 89. Anyway I will be running the stocker, I too have heard of issues running the HV pumps.

 

The big Q is to run an accusump or big pan. Possibly both?!? I hear the accusump systems are a huge engine saver so I'm leaning for that. Anyone not run either without issues?

[Tony G]

If I had the choice for one, than I would choose the accusunp for many reasons like cold engine start up with oil pressure,constant oil pressure and a reserve of 3 more quarts.

The oil pan is great too,but I have seen some issues like baffles broken off, leaks etc, so now you know why I have a accusump and not a pan.

Only my opinion.

TG,

on the 3 qt, what pressure to you like to put in it?

You know, on the air side.

Manual or auto valve?

 

thx,

For the accusump operation, is there any advantage to using the electronic vlaves and sensors? My understanding is you have the tank pressurized by air to xxPSI and the engines oil system uses/replenishes the oil side pressure as necessary. Before you kill the motor you turn off the hand valve to save the pressure/oil in the accusump for startup correct?

 

Where are you guys mounting the resevoirs? In cabin or under hood?

 

Thanks!

I wouldnt run the high volume pump unless you like replacing distributer gears. A NEW replacement pump will work just fine. I dont trust some of the aftermarket store brand pumps that have been rebuilt. yuck.

 

I'm also interested in the pan vs acusump debate.

no more than 6 ( six) lbs of air

use bike tire pump w/ value open on tank

mount in pass seat area where you can reach value

use only braided hose in cockpit area

cylinder gits HOT during operation

I dont have a oil cooler

but figure it helps to have this extra 3qts

[Tony G]

5-6lbs.

The engine oil pressure actually fills the cylinder and keeps it at 40-60lbs all the time,and I use the manual valve,as I have heard of the elect one going bad which is rare but can happen, only thing with the manual valve is that you have to remember to turn it on before startup, and cycle the motor up in RPM before you shut it off so you build some nice oil pressure for the next start up procedure,its actually really easy once you do it a few times.

Location of mine is on the pass side tunnel where the seat used to be so I can reach the manual handle and keep an eye on the bottle pressure.

The valve does not have to be attached to the Accusump cylinder. You can remotely mount the valve near the driver and put the Accusump anywhere in the car. I have mine in the right rear of the hatch area.

[mitchntx1548534714]

So you guys have a kettle of hot oil under 50 pounds of pressure in the passenger seat?

 

[K Shaw]

Those where my exact words I said to Rich when we where discussing this on the phone. I once (key word) had a line rupture to a oil pressure gauge and had some nice toasty hot oil all over my feet. Not goin to happen again.

Don't use the electric valve, I have a NEW bad one in my shop.

Lasted about 4-8 sessions!

Being electrical, Canton said SORRY!

i've also heard plenty of storys where the end of the tank blew off due to stripped threads.

[RichV]

Has anyone ever tried running a system like a nitrous setup? Run the lines outside the cocpit, mount the bottle in the back, mybe rig up a ball valve with a extended handle through the passenger floorpan. Leave the ballvalve under the car and just run the handle inside. Should be legal, I would think.

[Tony G]

The shorter the oil line to the motor the better, so in the back would not be a good idea.

crap, i should have seen that! well at least my rookie question had the side benefit of starting a conversation.

 

thanks guys.
