Most people have not heard of these guys but they make a nice Pump and good system.
The scavenge stages use "3-Lobed (individually timed aluminum roots style) Rotors" to remove the oil from the pan. They have been "in the game" for 50 years too. http://barnessystems.com/ Tom V. I personally have owned one of their Pumps for at least 10 years and it was nice 10 years ago.

I have no experience with them, but I'm considering using a Dailey Engineering pump (somewhere in California). They are Roots pumps, and offer an air separator stage integrated onto the rear of the pump stages. Their website has an impressive video of the air separator in action.

We've had terrific results with a Peterson R4 pump, Moroso pan (single -20 pickup) and a custom made 6 gallon tank. Last run was at 241 psi and we're going to try to get it a little higher this year.

Quality and a plan
I think all the ones listed are excellent choices. I have personally been involved in numerous Moroso dry sump projects and they all went well. I spent a good half hour talking to The Johnson family at the PRI show in December about their Johnson dry sump pumps and I will be using one of their pumps on an upcoming project.
My feeling is the design of the brackets and drive system, the plumbing and the oil pan itself are what you need to talk to a vendor about. Create a plan and implement it with a realistic goal in mind. Like Eric and Mike they have a specific application “Big power under demanding conditions” so I would say they have a very specific application and they talked to the vendor and created a solution. Again my feelings are times have changed. Most companies at least the higher end ones use a tremendous amount of engineering to design and build their products. Times have changed and so has the quality and reliability. Heck Johnson offers a lifetime guarantee.

I used a Moroso 3-stage gerotor scavenge pump on an aircraft engine test rig, running in an altitude chamber. It worked great.

Tom, agree with you, Barnes is a very well known name in the circle track world, sprints, late models, NASCAR, etc use their systems frequently. Because of the severe centrifugal forces associated with circle track racing, wet sump pickups would be uncovered causing starvation/engine failures. Windage would be the secondary consideration on this type on vehicle. Looking at their site, they do make straight line racing systems also and the founder started making systems for 392 hemi fuelers, he later branched out into other forms of racing.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
that's a dirt road...
