Or, you could spend the same amount of money and order a custom aluminum finned oil pan from Perry Mick (yes, it is finned both inside and outside). See pics. Paul Conner
The finned pan is another one of those ideas that absolutely must work, but leaves a big question of just how much good it does. I have to admit that I've been trying to figure a way to put an oil/water cooler in the new pan, or maybe some fins...
Rusty (still would like to use the small oil cooler)
How much good will it do? Just like we're discussing with the rotors, 5% here...10% there, and all of a sudden a marginal system turns into a performer. I can't believe a few fins would put the weight on par with the steel monstrosity that Mazda provides.
I've been considering a finned aluminum pan for a while (you know it takes a lot of planning to design a pan that won't fit in your mount, Paul 8*). I've been leaning to buying a slab of heatsink material. There is a class of products that feature a high density fin composed of folded aluminum or copper sheet. The base of these sinks tend to be fairly thick for some reason, but it looked like it would be fairly simple to weld on some sides and a flange (except that I don't have the equipment to weld aluminum).
My other investigation has been to weld up a pan out of .035 4130 and then rivet a heatsink on as the base. This is attractive since I've developed very good skills welding thinwall 4130. Differential expansion, dissimilar metals, corrosion resistance of 4130...lots of questions about this approach.
My other oil pan solution is to just weld a patch over the piece that I had to cut off to make way for my mount. But I'm really hoping to loose some of the weight from that thing.
If it would fit, Perry Mick's pan would be the simplest solution.
