Oil Pan for Curves

    cray1801 Too much is just right.

    After converting to my new setup I've experienced oil starvation when pulling higher G's. I first noticed this during skid pad testing, it will loose all oil pressure when approaching maximum lateral acceleration. I'm currently running the standard TA deep pan, which is more setup for Street/Strip. It is baffled at the front and back only. At first I tried an extra quart of oil, that did not work.

    I curious, has anyone tried to address this with a custom pan with more baffling? I would like to see a photo of the sump to get an idea of what it could look like.

    I also had another issue, gear oil would come out of the vent tube when making a hard left hander. That was an easy fix, with a "custom tube" with a drain-back feature.

    SRE, steve reynolds can make you a nice custom pan for your purpose. I have his custom pan with a belt driven oil pump. Far superior to stock oiling.

    Think John Lyons runs a dri sump system in his pro tour Riviera

    Pulling the motor this weekend.

    Will be following this thread to see how it all works out. Also what is incorporated in the SRE pan thats different from the rest.

    Understand, and I'm no expert:):

    The the lower sump of the pan for the curves will have baffles added, sometimes in all corners at about a 45 deg. angle. These baffles will likely have a trap door to help control the oil. Above the baffles there could be a short shelf that extends out to also help trap oil in the lower sump area of the pan. In addition there can be side kick-outs, protrusions in the left and right sides of the pan down low. Kick-out size will be dependent on available space of the installed pan. I'm guessing the kick-outs will extend about 2", and will be about 2" in height. The combination of baffles, shelves, trap doors and kick-outs will help to accommodate and maintain more oil volume for a better supply to the pick-up.

    Often times a windage tray can be incorporated into the pan or bolted to the bottom of the block, it will minimize the crank whipping the oil around, causing aeration and drag.

    I received the pan from Steve weeks ago but just now getting back to this project. I cleaned and painted it last week and hope to get everything back together and in the car before the first of the year. Big thanks to Steve Reynolds for coming to the rescue with the design and fabrication (and banging out the damage I did)!

    Project Complete!

    I am very happy how it all turned out. Here are some photo's if the engine/pan installation.

    Big big thanks to Steve Reynolds for the custom modifications to my old TA pan.

    About 3/8" clearance at closest point :)

    Thanks Craig!! Looks good installed! Glad we could make it work for you...……….. you did give me some "awesome" measurements to start with!! Good teamwork!

    The car looks stellar, BTW!

    Hi Craig,
    A bit off topic, but... I noticed in the pictures you seem to have the same Ridetech coilovers and suspension I do. Do you recall what weight spring you have in front and rear?

    1200 lb/in in front, I was concerned it would be too stiff but works great. Very happy with how it rides and absorbers bumps. Bumps do not upset composure of suspension when loaded.

    The rear is 140 lb/in I believe, need to double check that. Note that when lovering rear ~1.5" you will need to change your IC, I did this by lowering the UCA pivot point at the front by ~1". I show this in a previous thread.

    Have you had a chance to see if the modified oil pan solved your oil starvation problems?

    Hope to do a quick skid pad test this weekend if the weather clears up here in Raleigh.

    Must be nice to have that option. Cars are garage locked here in Chicago they salt for ice like crazy. It's pretty corrosive stuff they use. Not metal friendly. I'm excited to see how it works out. I had a T-style pan on my cobra and liked the ground clearance as well as the extra oil capacity. Good luck
