+1.5 Oil Pan

Keep your 2009-2016 Touring Model cool.  Todays Big Twin engine makes a lot more power and a lot more heat than its predecessor of 20 years ago. In 1993, the 80 CI Evo engine made 69 ft-lbs torque, according to online specs. In 2009, the 110 CVO engine made a claimed 115 ft-lbs torque. More torque equals more heat, but that’s just part of the story. The engine oil capacity of 4.0 quarts is unchanged from 1993 to present even though modern engines make a lot more power and a lot more heat. To the engineers at BAKER Drivetrain, this didn’t make much sense. Engine oil does two things. It lubricates metal-on-metal interfaces and carries heat away from hot spots like cylinder heads and the underside of the pistons. So BAKER’s +1.5 quart oil pan was designed to lower engine oil temperature by using a larger volume of oil to carry heat away from the hot engine.

     Anatomy Of A BAKER 1.5 Oil Pan

    The 2-piece pan design features a co-planar labyrinth to circulate hot oil from front to rear on the top level, and rear-to-front on the bottom level. The 2-piece construction was necessary because the bottom half being much wider than the gasket profile of the transmission case.

    Dynamic Road Test Temperature Readings

    Oil Temperature Readings
    On the "Dynamic Temp Readings" picture, the +1.5 oil pan was good for an average 16° reduction in engine oil temperature and a 20° reduction in stop and go traffic in sub-90° ambient Michigan temperatures. Note the engine oil temperature went up to 315° in the stop and go traffic segment with the stock pan. It is very bad for engine oil to go above 300°. Higher reductions in engine oil temperature with the +1.5 oil pan can be achieved in warmer ambient climates in the south. 

    1/2 Hour Static Temperature Test

    Most late model 2011 Big Twins, including our 2011 Road Glide, come with an oil cooler. The Factory oil cooler works very well when going down the road at highway speeds with air flow going over the heat exchanger but is marginally effective in stop and go traffic. The +1.5 oil pan is effective in reducing engine temperature on the highway or in traffic because it works through additional oil capacity, not a heat exchanger. To test this we did an static temperature test for a half hour on each pan while checking the temperature at 10 minute intervals . The +1.5  shows over a 9° difference compared to stock just at a stand still. 

    Pan Comparison
    The +1.5 pan oil capacity, up to the gasket surface, is 4.1 quarts. The stock pan oil capacity, up to the gasket surface, is 2.6 quarts. The side-by-side bottom view shows the comparative size difference. The +1.5 is 8.053″ wide, which is about 2 3/8″ wider than stock. To aid in cooling the +1.5 has cooling fins in the front and rear giving more surface area.  The installed pan comparison image really shows how the +1.5 completely fills the under carriage of the frame; looking like it was supposed to be that way from the factory.

    To realize maximum engine cooling benefit
    Install the +1.5 pan and fill the oil sump to 5.5 quarts (+1.5 quarts) to realize the maximum reduction in oil temperature. Oil fill level on the dipstick will read the same as stock. 

    To realize maximum oil blow-by reduction
    Oil blow-by on SE 110 engines is a chronic issue for aggressive riders. It is caused by the larger displacement engine building up pressure in the cam chest and the oil sump. This forces oil up the push rod tubes, out the head breathers, into the air cleaner and all over the right side of the bike. Harley tech line is advising dealers to run the stock oil sump 1 quart low to increase the volume of air in the sump. This corrects the blow-by issue but makes the oil temperature skyrocket. By running the +1.5 pan at .5 quarts over stock (4.5 quarts) the blow-by condition can be cured with a small improvement in oil temperature reduction. 


    Fitment
    The +1.5 will fit 2009-2016 Touring Models.*
