1971 Firebird Build ("The Other Woman", a.k.a. Project "T.O.W.")

[Panteracer]

I was always told you want a high volume
Pump not high pressure. Maybe dry sump Ls type
is different. I had a high pressure in one of my Poncho
motors and it washed the bearings.

Pantera has a high volume pump that the engine builder
prepped before installing with an Aviad pan With a mech
gauge shows 60 psi almost all the time. Motor is 10 years old
and sees track and autocross turns at 7500 rpm with steady pressure

Best motor I have ever had and I have lunched over a dozen
in my lifetime. But it is a dart Ford. Flame suit on

This is where I mounted the LS7 tank in SWs Camaro

Peterson 2.5 gallon on a LS in that location.

Isn't that a 1st Gen F-body?

What's up Eric! That's another proven location for a tank. Stielow and others have placed it there AND thrashed on the cars successfully.

Yes it is - it was just for context. Here is Finch's 2nd gen (he built that green 69 pictured as well) with the tank in the same location.

From the people I have spoken to, this doesn't work. You want the oil to have time in the tank to remove the air (via the baffling in the tanks), and a smaller tank allows less time to do that. I also can only run a single pressure stage, I'm not sure how / if I could even plumb 2 tanks.

It's really easy. Larger line (double the size) below the fill and suction line between two equal sized, baffled tanks. You're talking with Stefs. Ask them. They did it for my truck.

I think you're over thinking this.

But how do you deal with the return? What type of pump did you have? Separate suction/return stages dedicated to each tank?

Oh, and wouldn't be the first time!

Bob,

Maybe I have this all wrong... I have been avoiding the High Volume pumps as I assume those would make the problem even worse. Am I wrong on that? When I read high volume, I'm thinking that pump will suck the pan dry faster and push the oil up into the top of the motor. Is that wrong?

I have a phone call in to Schumann's who sells a ported and modified LS wet sump pump. I've read good things about them on various LS forums. I want to see what they have to say. They only do HV pumps, so maybe I'll learn more there too.

You know that I know you can make it work. But the inner fender and core support in that area are very different on the Camaro and Firebird. I was starring at it last night. I considered having Stef's build a rectangular tank to fit in that space also. We'd have to move the AC components, but that wouldn't be a huge deal. Just new lines...

There. You convinced yourself. Go dry sump. See, that wasn't so bad.
