I have confirmed it fits in the 6 speed oil drain plug. I will be confirming it fits in a diff hopefully tonight.
Thanks for posting this info. Though did you just remove the magnet? I want to do this but am worried about not having the magnet. Potentially I could move the drain magnet to the fill port to keep it, though that's not ideal.

CSF has a new dual-pass 8 row fluid cooler that has the entry and exit on the same end. It should make for tidier installations.

Has anyone data logged temperature differences of diff or trans fluid with and without flat bottom undertrays that cover the entire unit? Or any tests with flat undertrays with NACA ducts specifically pointed at heat sink fins on the diff or trans?

All I know is that Brian from Goodwin Racing apparently said he got away without the use of any coolers, and that the general MT opinion was "the diff runs hot as is". I've not found conclusive DATA, but the top folks apparently do run designated oil coolers. Dunno, maybe it's a matter of local climate, or personal preference in which religion you want to believe in? Will additional coolers help? Likely. Is it worth the complexity IMHO? probably not, I'll stick with homemade NACA ducts. Because I'm a lazy bastard.

Updated the OP with some more data and info.

Parts sources

The Genesis (motorsports) pumps are much nicer (and more expensive) than the generic ShurFlo RV/Marine pumps. Tilton a few other companies make even higher end pumps but the Genesis seem like 80/20 to me.

A few of the Setrab fanpack options. Other good heat exchangers out there but Setrab are world class and still affordable.

Are there any recommendations as to what size of cooler and fan is needed for say 280whp in a location with no airflow (attached to rear bulkhead on opposite side to fuel filter).

I'm not sure whether this would be enough, or something much bigger needed.

I know this forum doesn’t like to spoonfeed, but I’m having difficulty working out how to get the lines from the gearbox ports to the rear of the car.

The route to the front looks much easier, but the only place I can put it there is in the front right wheelarch, which is
1. More weight up front
2. The lines would have to pass through intake side of the bay, which is a bit of a crowded disaster on my RHD cars with a reroute, dual feed rail plus regulator etc

The route to the back is less straightforward. I saw the supermiata video that put the lines over the top of the 6 speed before the shifter, but this seems too tight on mine (drop mounts on the supermiata car? Mines stock height) and also I’ve still got the stock center console so all of the screws for that stick down and would destroy an oil line.

it looks like I could follow the PPF the whole way back and pass it through the rear subframe, but this puts the lines close to the diff flange (should be ok once secured, but doesn’t look ideal) and there’s a long length exposed to radiant heat from the exhaust.

Does anyone have a clever (or obvious!) routing I have missed? ( I blame my facilities, trying to do it laying on the floor in a 1 car garage with no lift)
