Default Home made/designed radiator

After purchasing a new Mishimoto radiator and unboxing it, I was rather disappointed with the build quality and poor welds. I looked at other local brands, but they too were similar in construction.
I then decided to try and build my own (never made one before). Its taken many months, but finally tonight the last piece was completed and its ready to be dropped off to the welder.
The fan mounts were 3D printed and the inlet dome end was cnc machined. Filler neck is made by speed-flow and I machined up a sleeve to match the oem overflow hose which was pressed over with a dab of loctite.

I really like the Fumoto drain valve on my oil sump, so decided to put one on the bottom end tank to make it easy to drain the coolant. Most aftermarket radiators just expect you to cover your arms in coolant when loosening the drain bung.
I drew the end tanks in CAD and then had them laser cut from 5005 and precisely cnc folded (the entire top tank is a single piece).

All the other fittings I machined from 6061 based exactly on the factory dimensions. The new radiator is still the same size as oem, but with a thicker 38mm core (its still 50mm thick which is the same width as the plastic end tank crimping). Fitment in the engine bay is perfect and absolutely no interference with the hoses or aftermarket SSI headers.

To confirm fitment I first mocked everything up from laser cut MDF and 3D printed the fittings. Lucky, as I did indeed make a whoopsie.
I find the kitchen bench is usually the best level place to work.. once everyone has gone to bed

Unfortunately with this build Iím finding that a lot. Many aftermarket products donít fit correctly and need to be modified. Sadly when contacting the manufacturer they donít seem at all surprised and simply refund or replace. I would be horrified if one of my products had a defect.

Cheers, since posting this it was immediately dropped off at the welder the following day. Unfortunately he has a huge work load and Iím still waiting for it to be glued together.

That looks great! Whos core did you go with?

We use an industrial style drain valve on our radiators. I don't see why the Fumoto won't work, it's just more expansive and takes more space; I could see it being too big to use on a GD chassis if the OEM subframe is still in use.

Looking forward to your next updates.

Iíve never heard a weld on bung and bolt being called that before (industrial style drain).
The core is locally produced in a relatively unheard of place known as Australia (some even dismiss its existence as fake news), though its not designed on any catch phrase technology. It uses an extruded tube with a 1.6mm ďheel and toeĒ (for longevity and strength).
Luckily I donít have a GD so Fumoto fitment is not an issue.

Finally got it all welded up and pressure tested. Next step to get the end tanks powder coated satin black.
Some figures comparing it to oem.

Custom Radiator (ADRAD core)
36mm thick core
84 tubes
6.2kg

Oem Radiator
26mm thick core
76 tubes
3.3kg

I made it exactly the same overall dimensions as stock, though has more tubes and they are wider.

Holy cow that is beautiful. Keep up the good work. Better yet, draw up all the dimensions and specs and work with someone like KillerB or Grimmspeed to put it in production.

Cheers. I initially had a lot of interest but using a high quality core drives the price up and peoples mindset these days is ďWhy, when I can buy four chinesium ebay ones for that priceĒ.
Killer B uses F1 technology in their radiators, so I canít compete with that level
