Let me know if anyone has any questions

makes for hard welding oil returns now

Nah. Welds the same as the sheetmetal pans

what is the difference in this and your current model (assume both for ej25)

Since these are now cast, are they going to be cheaper than the current welded units?

Yesssssssssssssss! Racecar was in need of an upgrade!

We're not a company known for doing anything on the cheap. The advanced casting process we use allows for thinner, stronger, and lighter products.

A good comparison is look at our intercooler end-tank inlet/outlet. We can have a horn shape taper at the edge, a thinner wall provides a larger opening (more flow), and the thin wall means better exposure with less turbulence going into and out of the core.

For the pan is means no tapered walls, which means no compromise to oil capacity, and an small improvement in strength, without a significant weight tax.

From a performance perspective, there's no change. Both versions can handle anything you can throw at them. The cast pan is now our mainstream product, but we are still making the weld-porn fabricated on a made-to-order basis.

Perfect. I'm speculating here, but since you're starting to really dip into cast aluminum fab and are more race-centric are you going to possibly focus a little on the rear of our cars in the near future... you know in the diff area

Are these shipping already with your 3-piece ej25 pickup, pan and baffle? Thanks

Rear end? Like what specifically?

Yes they are!

I'm not insinuating that you are a company that does things on the cheap. I could only make the deduction that since you no longer have a skilled professional slaving over welding up these oil pans from individual pieces of aluminium, and you can now knock these things out like proverbial sausages, savings might be passed on to the consumer. Would you say that casting the oil pans is a more labour intensive process than your previous construction technique?

I think you are solely looking at material costs and assuming after the pour they are completed. There is far more process time that goes into the cast product than the fabricated version. The machine work requires a CNC operator with some experience, so you're also trading welding labor for CNC labor.

Castings require a material cert at melt (samples for the mass spectrometer), the pour, band-saw trimming gates/vents/etc., x-ray inspection, grinding gates/vents/flashing/etc. flush and any other abnormalities, inspection, heat treat to T5, test, heat treat to T6, test, bead blast, then off to machining, post machining inspection reports, welding the baffles, final fitment and QC checks, then washing.

With the previous process the sheetmetal certs from the supplier (made in the USA of course), laser cut, inspected, CNC brake, inspected, fit-up, welding, finishing, final fitment and QC checks, etching, and washing.

We are trading labor for materials and process. The costs are within a few dollars of each other (not including the +$30K we've got into casting tooling costs). The fabricated version price will go up though (and only available directly through us), since they will no longer be production batch made, but instead MTO, so there are losses in productivity.

You are X-ray inspecting these? Have you found any defects? My earlier comment about harder to weld, Is the fact that cast is a dirty metal and much more difficult to weld, 90% of time cast isn't welded its replaced

In my opinion this is an absolutely critical step, especial early on when you're optimizing gates, vents, etc... The casting software simulations have come a HUGE way since they first came out, but nothing replaced real world testing and verification.

It's not harder to weld? It requires some adjustments, but lots of cast aluminum things get welded, like our cast endtanks to our intercooler cores We make three different kinds of headers that use a cast collector section as well.

A whole lot of sportbike motorcycle rear swingarms consists of cast pieces welded together.

Billet is just a huge chunk of cast metal.

You are 50% correct, Billet is also formed by hot rolling as well as continuous casting.

Have you found any defects in your castings yet?

Gummy bears are awesome, and so are KillerB parts

So.. how much are these?

Wow some manufacturing experts maybe should build there own! Just my 2 cents billet has to be cast first before it can be rolled or forged.
And the quality of a cast is totally dependent on the person and process doing the cast. Last but not least, go buy that other companies cast aluminum subie oil pan if you think your getting ripped off. Oh wait what company was that?

ARC made one.

-When will it be on your site so we can check cost?

(edited, somehow missed the capacity)

-Is it lower down than the oem pan / less ground clearance?
-Does the oil pickup tube have to use adapters to lower like on your other oil pan?
-What do the internal baffles look like?

No casting is perfect. If you've seen enough billet, even it can have imperfections. The casting process we use produces parts on the high end of the casting scale in regards to capabilities and quality. At this point we've processes just under 500 units and there were 2 units that had a visible void beyond my comfort level. So we hit them with the TIG torch to see how they react. So far, it's been uneventful, adding a dab of filler rod and all is good. a 'bad' void will have contaminants or may be so deep it can blow through the thickness once you apply heat. We've not seen this yet.

As far as QC goes, the parts pass through several hands for visual inspection and x-ray inspection. Anything questionable gets evaluated to determine a coarse of action; back into the pour, scrap, or rework.

Having worked with many castings over the years, I am really impressed with the process. As far as durability goes, I would say these are stronger than our fabricated version.


Same price. The fabricated pans will be having a price increase probably around the 1st of the year. They take a ton of time to make.

Yes they did. It was widely accepted too.

If you buy through the site, you will get a cast pan. We're going to be updating the pics soon.

Yes. It still fit under the OEM bellypan though

Yes, when going to a deeper pan, the pickup needs to be brought down with it. We've been using this setup since ~2010 without issue.

Same as on the fabricated units, flow through style. This design performs much better than anything we've ever seen or have test data on. The flat baffles (or worse baffle plates sandwich between pan and block) are horrible, some performing worse than OEM.

Cool deal. Anyone have a photo of one installed yet, and ground clearance?
