Care to enlighten us as to what CAD package you are running for the design of these Porsche Oil Coolers? Also, what CFD package you are running for your flow analysis and heat transfer calcs?

I'm not calling BS... ok maybe I am... just a little.

Over selling products is a far cry from engineering or design.

In case someone has plans to modify a Mazda Cooler or similar and wants full flow, I have these M30 Alum Weld Bungs available.............



To convert a Mazda Cooler to a Flow-Through design, I also offer this in M30............



Here is a hose being made up to connect the factory front fender cooler with a second center cooler........



With the correct Crimp of course...........



Please email me for information......

Unclebill, thanks for annoyingly sharing your resume and you seem to be stuck on this Mazda cooler option. If you must know, I have degrees / certs in manufacturing engineering, industrial design, quality control, machinist work background, Unigraphics / Siemens NX / Solidworks / CMM, etc.. and I've been in the Porsche and Motorsport industry since around Y2K. It's kind of what I do... I continue to not care about your choice of heat exchanger. If I was bullying you, you would know it. Stop playing victim and don't test me. Instead, watch your tone, be cool and constructive in here.

Now based on my experience I don't require FEA reports to form the option that having a small feed and return fitting is a smart choice for this application. Yes the factory oil thermostat has internally smaller I.D. ports about the same size as -12AN. That is larger than 9.5mm. I respect the original system engineering and value it's baseline performance. That being said, I'm open to all more efficient options.

Ken, I looked to see if I still had the boxes for my oil coolers to get the part numbers for you. I do not have them anymore. I looked on Summit racing's website, and found these. I do not know if these are the exact ones I have or not, but these look close to what I have. Mine are dual pass as well.

Another nice oil cooler you can get in a salvage yard is the one from an old Jaguar sedan with the 6 cylinder engine. I got one real cheap in a local U pull it salvage yard years ago.

I filled it with mineral spirits, shook it around until I was sore to clean it out, made up some aeroquip stainless braided lines with 90 degree fittings, and installed it in a hot rod BMW 320i with a 3.5 liter 6 cylinder motor I used to drive around.
That car was black with no AC here in S. Florida so summer driving sucked but it was fast.
These days it's rotting away in my driveway and I store stuff in it.

I had another thread on here using an aftermarket new Mazda cooler and len's fittings and lines, modified to run straight through...

Drove on it 3 times so far, works great. Car never goes past the first line, at least at 70 degrees. 1st track day this Friday.

New cooler, $80 or so.

Looks very stock. My oil pressure actually went up. That I don't understand. Used to have a smudge below 4 bar most of the time. Now it's a smudge above... Must be the oil temp drop.

The Mazda cooler can not be fender mounted, it is for a front center location.

For a cooler with AN-12 fittings do a search on eBay. Lots of inexpensive choices from the UK, though most likely they are made in China.

For one made in USA look at the Earls or Mocal products, they both have many to choose from. AND, the AN-12 Fluidyne cooler from Summit Racing posted by turbobrat (Brad) above looks like the best of all.
