We bought a new 2007 FL to use for 7-speed transmission development work. The first thing we noticed was how hot the damn thing ran. In traffic, we could see those little heat wave squiggle lines (maybe a flashback) coming off the motor. The 4-qt capacity, unchanged since 1993 (when the 80” motor made 49 hp), seemed inadequate.

So we designed a new pan in SolidWorks with a 5 qt capacity by going wider not deeper, hence the +1 Oil Pan. Taking a closer look at the stock pan we discovered it has the oil pickup and return in the front of the pan within 2” of each other. So we put the pickup in the rear of our +1 Oil Pan and the return in the front for better oil circulation.

- Cast oil pans are 1-piece design and made with A356-T6 aluminum
- Billet oil pans are 2-piece design and made with 6061-T6 aluminum
- Feed and return on the stock pan are within 2” of each other. BAKER pans have feed in the back and return in front

Anatomy Of A BAKER Oil Pan
The +1 Oil Pan replaces the stock plastic baffle system with integrally positioned baffles as part of the pan, casted in on our cast pans and machined in on our billet line. We also have the feed location moved to the rear of the pan and kept the return location in the front for a more complete system circulation. Looking at the images below you can see how the oil would flow through the BAKER pan and the internals of the baffling system. The Factory Oil Pan uses a removable plastic baffle system which can cause wear on the inside of the pan from engine vibration. The oil feed and return areas on the factory pan are within 2 inches of each other located in the front of the pan. This can cause the tendency of hot oil getting sucked back into the motor by seeping around the plastic baffle.

Stock vs +1 Pan Temperature Readings

Oil Temperature
Temperature of your motor oil plays a big factor in the life and longevity of your motor. The temperature data chart shows an average of 14° drop with the BAKER +1 pan vs. stock.  It also shows the longer and hotter the ride, the bigger the temperature differential. Some of our customers have recorded up to a 30° temperature drop in the Nevada desert during the summer where temperatures can reach 110° easy.

Stabilizers
After getting the speed wobbles on a high speed sweeper, we realized the need for this pan to work in conjunction with stabilizers on the market, so we tested it with both types – It really worked, no more speed wobbles! So we incorporated two bosses on the bottom to directly bolt the heim joint of both types of stabilizers to the oil pan.

BAKER +1 / S&S Adapter kit
We highly recommend the +1 Oil Pan for S&S© T124 applications. It makes a lot of power and a lot of heat. The oil feed and return on the right back of the motor is unique so the following adapter kit is designed specifically (and required) for the +1 Oil Pan and the T124 motor. Special adapter block to route the oil lines for the BAKER +1 Oil Pan;  PN 5QT-1160

Note
If you are installing a oil temperature sending unit on the oil pan; install the sending unit before installing the pan on the transmission housing.
