Now Available - New & Improved F-Body Trap-Door Oil Pan Baffle We recently released a new and improved version of our trap-door oil pan baffle for the LS1 F-Body pan. The new baffle features a third trap-door which traps oil during acceleration, so the pickup is now completely enclosed by trap-doors.
Our baffle offers track-proven protection against oil starvation for road racing, drag racing, drifting, off-roading and even rock-crawling.
Our baffle is a a 100% bolt-on replacement for the stock steel baffle and weights 1.3lbs less.
Price is $199.99 + shipping (approx $8.50) - less expensive and more effective than most aftermarket pans!

I spun my #6 rod bearing last time at Thunderhill even with a 3-qt accusump, so I was concerned about running the new motor at Laguna last Monday. No need to worry, I never saw the oil pressure drop below 50 and the motor ran strong all day. I am running 12" wide slicks on a race-prepped RX7, so cornering forces are up there. Much cheaper than a dry sump.
I highly recommend this product. It is a clear improvement over the factory stamped steel baffle.

I was not paid, sponsored, or offered any discount to write this!
Instruction sheet is professional, thorough and well detailed.
Manufacturing/production quality is first rate!
Fit and finish in the F-body oil pan is amazing!
The baffle is tight to the pan floor and tight to the forward wall of the pan! It is apparent the designer spent a good deal of time to make this happen.
In looking over this baffle from a design standpoint, it is also quite clear this was not just drawn up *****-nilly and sent to production, it was methodically engineered, every part, panel, nook and cranny has a job regarding oil control to and around the pick up tube!
For those wanting to build their own similar design, my advice is don’t waste your time. For the money, you will be hard pressed to even come close to this baffle.
My only addition to this is don’t forget to port the oil passages above the oil filter! Careful not to go too far in porting and bust through to an adjacent cavity. Just need to open the restriction at the intersections.
Thank you to the crew at Improved Racing.

The other changes we made will improve performance in road racing conditions slightly, but nothing dramatic.

The vertical guides welded to the top of the baffle catch windage oil that is being whirled around and guide it into the pickup box.
The slots cut on top of the baffle help improve drain-back into the sump, so that oil doesn't just accumulate on top of the baffle.
The small bent piece welded to the bottom of the top plate covers up a hole that is cast in the pan for the oil level sensor. Basically it just ensures that all of the oil flows into the sump box under braking, instead of around it.
The open side of the box might confuse some people. This portion of the baffle sits up against the front of the pan.
Here are some photos that might help you understand how it works. I will try to make a video explaining it or something too.
Does that help at all?

Might be a dumb question...but why is the hole for the rear trap door smaller than the holes for the side trap doors? What benefit does that add? Wouldn't you want them the same size? Seems like it would limit the amount that comes in from the rear of the pan.

See the V-shaped walls cast into the pan? Those walls funnel oil into that one hole under braking. So the trap door hole can only be as wide as that opening in the center. Also, the size is large enough; if you look at a Corvette batwing pan, there are walls around the pickup and all of the openings are about that size, even a little smaller.

This is a new model that was released in September. The old model only had two trap doors, this one as three, as well as some other minor improvements and revisions.

That hole is narrower because of the design of the pan:

this is a dumb question im sure but since this is for road racing, drag racing, drifting, and off-roading, how would it fair for a Daily driver? and whats this about porting the oil passages above the oil filter?

Porting the oil passages above the filter is something a few people have recommended to supposedly improve oil flow, however I'm not aware of any data indicating that this works or is beneficial (or harmful) to the engine. Unless I saw some kind of concrete data proving that it's beneficial, I would not mess with it, because it was probably designed that way by GM for a reason. So I don't recommend doing it.

Man, that looks like a great product. I hope you sell a lot of them; I'll bet getting one as soon as I find one more reason to jack up the motor and drop the k-member (again 
), lol.

I have had no oiling issues with my stock sump/pan/pump during road racing situations. Never saw an oil pressure drop.
I still got one! This is a great price for security. Also, it's a great addition or alternative for a pressurized reserve system. I was rebuilding the engine, and I figured that >$200 was a small price to pay to possibly save a $10k engine.

Here's a video review by one of our customers:

We will be making our own videos soon that demonstrate how the baffles work in a little more detail.
