Oil Pan Baffle

Wilhelm Raceworks Oil Pan Baffle for 2GR-FE
Wilhelm Raceworks Oil Pan Baffle for 2GR-FE Wilhelm Raceworks Oil Pan Baffle for 2GR-FE

The Wilhelm Raceworks oil pan baffle for the 2GR-FE V6.  Designed to prevent oil starvation due to hard cornering, while being both cost effective and easy to install.  Consists of laser cut steel baffles with rubber oil control flaps.  Data from my own track and autocross sessions with the 2GR-FE has shown oil pressure drop on right hand turns, which this helps to correct.  I recommend over-filling the pan by about a half quart (1/4" to 1/3" on the dip stick) for best results.  See this article for more detailed information.

The baffle is designed to be a close fit to both the upper and lower oil pans.  This enables it to be fixed in place with a bead of RTV around the perimeter of the upper baffle.  Welding is not required, although the baffle can also be welded in place if you have the means and desire to do so.

For those who previously purchased the baffle and want to add the drain baffle piece to it (as described in my blog), it is available separately.  This piece is included with the purchase of a baffle as of October 2022.

One of my customers made this very nice video showing the assembly (baffles are shipped fully assembled unless requested otherwise) and installation process.  Thanks Russ!

    Do your rubber flaps need to be replaced every two years or 18000 miles, as recommended in the owner's manual for the OE baffeled pan?

      Not as far as I know.  I have had the same set of flaps installed in mine since 2018 and they looked fine last time I had the pan off (a couple of months ago).

    Do you know what kind of rubber? (Silicon, buna n, nbr, etc) the flaps are made from?

    And any interest is providing a +cost option with metal gates (even drill your own holes and rivet yourself) for the folks who worry?


    Fair amount of the lotus community is put off by the rubber flaps I think due to the GTs coming with OEM rubber flaps that are known to stiffen and get more brittle over 2-4 years of operation.

      The flaps are hydrogenated nitrile butadiene rubber, which has very good resistance to both oil and high temperatures.  Mine were in perfect shape last time I had the pan off, which was after about 4 years of use.

    Does this work for drag racing?My logs show oil pressure loss during launch and between shifts resulting in spun bearings

      I haven't specifically tested it under those conditions, but I would think that it would help.  The baffles will reduce oil slosh in the front to rear direction as well as side to side.
