I know 3 pass radiators have been discussed before, and some are advertised as 3 pass but aren’t a true 3 pass design. @Fabman has a nice write up on how he modified his Fluidyne by welding plates in the end tank. I ordered Fluidyne part #FHP30X-05MU-3P, which they advertise as a 3 row, 3 pass. This part number has the proper plates welded in the end tanks similar to Sal’s.

Bingo, that’s it! I didn’t know they made those. Kenny Brown offers a radiator like that but this is the first I’ve seen besides his and the ones I make. Great find!

Nice info on the radiators here. I bought the Kenny brown triple pass after learning from your teachings on the subject Sal. Thanks by the way! Anyways, the Kenny brown triple pass is the fluidyne radiator a couple posts up. Branding and all. Looking forward to seeing how it does.

Short block is scheduled for delivery tomorrow. I ordered it December 2nd. A bit longer than the 3-5 week estimate, but not too bad considering the holidays and they were closed between Christmas and New Years.

What a time suck the oil cooler and ducting turned out to be - pretty much spent the entire weekend to get it mocked up. I started with a mount that I bought from 06mach1 which hangs the cooler from the radiator support, fittings on the bottom. The 948 is large enough I wanted the bottom of the cooler secured as well, and I wasn’t keen on the AN fittings hanging down in the open section of the lower grill - right where 80% of the road debris comes blasting in. By turning it sideways, it was possible to move it back closer to the radiator. The angle iron added to the radiator core mount doubled as a bracket for the ducting. It’s been 10+ years since I’ve fired up the MIG torch, so I spent a fair bit of time getting back up to speed and building a lower frame for the ducting. Add 3 trips to the hardware store for this and that……hard to understand why this project drug on!

Here’s a few shots of the the mock up - still need to blow it apart and spray paint the bare metal brackets. I won’t put it all back together until the engine is back in the car.

Now that has to be one of the cleanest home built solutions I’ve seen.

This is absolutely gorgeous. Great inspiration but also makes me sad because I have so much extra crap in the way (oil cooler lines, P.S. lines, ac condenser lines, etc.). I spent a good 10-15hrs on doing my ducting and it didn't come out good.

Also, what BTU is your cooler? I've had issue with 160°F mishimoto tstat not opening while driving on the street....the oil never gets hot enough. So be sure you've got the 180°F or 200°F t-stat because I know you still drive this guy on the street. You probably know this already though ;)

Thank you! I still have to add the -12 oil lines on the drivers side of the cooler so it will clutter up a bit. It’s all built out of gloss black Alumalite, so the white protective layer will come off after final assembly.

Setrab lists the btu/hr rating at 69,000-96,000. Had to read the footnotes for explanation on the big range:


“EOC hp and btu/hr range based on specific performance parameters that if varied may result in different performance results. Low EOC hp and btu/hr range based on typical wet sump high-performance application and typical variable parameters. High EOC hp and btu/hr range based on typical dry sump high-performance application and typical variable parameters. Wet Sump Parameters include: oil flow rate, 5gpm; 20/50 engine oil or similar; 130ºF ITD; 60mph airflow. Dry Sump Parameters include: oil flow rate, 8gpm; 20/50 engine oil or similar; 140ºF ITD; 80mph airflow.”

The new engine is leading to other mods including long tubes, so my street miles will be greatly reduced once the plates expire in May. I’m going the no thermostat setup - using the Ford Performance adapter plate, remote mount filter and -12 lines throughout.

Oh no, another s197 street car bites the dust! Haha.

I know coyotes put more energy in the oil than a 3v, but I'd definitely keep an eye on oil temps, I've got I think a 50kbtu cooler and I sometimes struggle to get the oil up to temp in the colder morning sessions here in socal (30-50°F ambient). I sized the heat exchanger to get 280°F 50wt oil down to 230°F on a 100°F day, completely not realizing the consequences of how it would behave while driving on the street on a cold day.....:ohdamn:

Looking forward to seeing this thing in action
