Dry Sump Questions - CB vs AC & tank placement

[type1.racer]

Autocraft vs CB
Looking for opinions on the CB dry sump pump vs the AC 2 stage. Not sure the pros/cons on one over the other. Aside from the AC pump eliminating the factory pickup and pulling from an included sump plate. There is quite the price difference between the two aswell. The CB pump seems to have some really good reviews and for the price its hard to beat. Just curious what the AC pump offers to justify that high price tag, is it worth it?

Mounting Location
Also curious where people are mounting tanks that aren't custom made. Really hoping to buy something off the shelf (ebay probably) and mount it. Inside the car is the easiest although seems a little scary if something goes wrong. Plus I need to lookup rules around having an oil tank in the car with no separation to the driver. Other option would be in the trunk but that would be some LONG lines. Right now im thinking cut a hole in the package try and let the tank sit maybe 3-6" in the car and the rest hang down by the trans. Then have a small box built to go around it.

Quick Car Details
Car is an IRS bug, fully caged. has an 091 6 rib, and an oil cooler mounted to the down bar of the cage on the driver side (where its welded to the frame horn). Not much room under there. Passenger side i have nothing, inner fender well on the passenger side is also clear. Although im not sure if there will be enough room in the fender for a tank (fenders are +3 in the back). Really I need to get out and take a bunch of measurements however i'd still like some info from those of you who've done it.

I have 4 cars with dry sump set ups on them, but none with autocraft pump so hard to answer on that, i do have a cb pump on one as it does the job well [but its only a mainly road car, for a track car think i would use something with bigger gears and more scavenge sections]and allows a reasonable size pulley still, not sure the autocraft pump does? I also use a dailey pump on couple cars and it is very good piece, but price reflects that.
On 2 cars i have tank where back seat would be on opposite side to battery, one is generic Steff round tank and other i made to fit the space so back seat fits still, i do have one car with tank up front and apart from weight balance its just not good idea

cheers Richie

We race two dry sump cars, both with the CB pump. The Autocraft pump is excellent, but the CB has really proved itself with us. Our Ghia, is a sprint car in Historic Sportscar Racing, which means 7000rpm at times, and our other car is a LeMons 12 and 24 hour Super Bug endurance racer that we try and keep at or under 6000rpm. We're in our 9th year on CB dry sumps.

The Bug has a custom made square tank that fits where the battery would normally be in a street car, under the back seat. The Ghia has a standard round 3-gallon tank mounted in the same position as on the Bug, with a circular hole cut in the floorpan to set it as low as possible and let's us reach the tank drain plug.

Round tanks provide swirl to the oil and aids separating foam from liquid oil, but our square tank baffling and plumbing has never created a problem.

Last is the issue of catch cans. Porsche never used catch cans on the 4-cam Spyder engine or the 911. Our Ghia vents from the alternator stand oil filler (whole cap area) on an 16AN line directly foward and down to the tank, right through the firewall. The tank has an 10AN vent to filter (atmosphere) line to get rid of dry sump tank pressure. The Bug still has a ventilated catch can that empties to the dry sump tank via a 12vdc pump, when the driver can remember to do it.
