I know a lot of people have successfully fitted the 50mm versions, but has anyone managed to squeeze in a 70mm alloy radiator? May need to loose the shroud but with the inner guard trimmed back it looks like it might fit ok and clear the fan.

It may fit a Rover Mini

I have a 50mm in my car, I didn't cut the body but had to take a fair bit out of the shroud on the engine side. I think you'd have to lose the radiator shroud panel off the inner guard

Yeah it would have to go but no loss really. I see MED also sell a wide 70 mm (68 mm actually) alloy extreme race radiator, albeit much more expensive at close to $600 but claimed to be the ultimate in cooling capacity.

Hi, I have a 50mm in my cooper S, no body mods at all , but I did have 2 engine mounts made a thicker one on radiator side, and quite a thin one under clutch, it does make fitting bolts on clutch side awkward, but its a nice fit. I have a 70mm on the supercharged moke, but you can lay it on an angle away from the motor. I dont think you need 70mm on a road car, and one fact that nobody ever mentions is the front height of the car, I recently tuned a supercharged car that has blown several headgaskets, they had tried another radiator for the drastic overheating to no avail. apart from tune issues I would be 100% certain that as this car had 6" wide wheels, and tyres that touched the guards on bumps, it does not have enough airflow past the tyre, and thus under the guard is just a continual red hot oven.... you might like low cars for appearance, but there is a big downside. It also had evans coolant, which in itself can make the engine run hotter, due to its different viscosity, as it does flow through the cooling system at a different rate. And i am not convinced on larger diameter water pump pulleys on road cars. Sorry if I have hijacked a 70mm enquiry into cooling system smack smack cheers Lindsay siebler

Don't dismiss the shrouds. They are there for a purpose. Properly directed airflow through a properly sealed shroud system (who still has the rubber strip attached to the inner guard shroud eh?) is a far easier way to cooling than trying to fit a larger radiator in that requires removal of the shrouds. You could find that there is actually less air flowing across the core because it is taking the path of least resistance in the gaps where your shroud used to be.

It was a pleasure ausmini. I'll miss all you misfits and reprobates

Bit of discussion about these on the uk turbo mini forum, those that have fitted them seem impressed.

I have fitted a 50mm chinese alloy to a deluxe but had to cut some away from the inner guard and modify the shroud mounts.
I also had to cut some out of the bonnet sill as my engine is about 15mm further forward to make more room for the supercharger. I ended up using crimp weld with the smallest bead I could get (like a door seal) and put it around the inner guard shroud to make a perfect seal against the rad. Big improvement in cooling. I am now running 13psi boost so was running into some cooling issues. Now sorted.
