Yeah my SU used to ice up all the time. Solution: I no longer run an SU

Heh, I used to run twin Amal Monobloc bike carbs on a 1058 Mini motor. They didn't ever ice up either! Must be an SU thing....

For the Mini Minor racer i have the heater matrix in the cabin with a bilge blower on it. I'll just add a bit of ducting to the window so the cabin doesn't get too hot Not a good look for a road car though

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

I was running a Holden in a 24 hour race about 10 years back and the tripples on the Holden didn't ice up but the Webbers on a lot of other cars did!
I think it depends a bit on the under bonnet temp and the temp of the air into the carbs..

Hey Chong, I was going to buy that, but didnt have enough cash. Good score mate!

By the way, I saw you on Sunday. It didn't click until after I had left that it was you. Next time I will say g'day.

Anton.

Yeah mate, I thought I was supposed to see you there and Makka did mention that you were there but it didn't occur to me to ask which one was you! Next time!!!

I run a motor very simular to kevs, but less compression, bit more cubes, but less headwork, bit less power, although im sure some of that is to do with Kevs fastigeous engine maintenance.... Anyway i did originally have a cooler on it but after a nasty cranksnapping incident i needed a rebuild, Graham Russel told me not to waste my time with an oil cooler (and asking for trouble using the old one, nomatter how well i flushed it out), and definately not to bother with fancy (read: expensive) radiators, he also told me my car would likely run too cool with the minimatic heater core i had installed (like kevs) so i pissed it of, before this i was driving blind (guageless) so i had no idea how hot the car was and what my oil pressure was doing.... Incidentally, when i quizzed him about thermo fan settings for a customer the other week he mentioned he cant get cars to run hot enough when using thermo fans

So I just got my stock radiator flushed and it is fine, having said that though, after a few hours of hard driving on the weekend my oil pressure dropped quite a bit (i currently run HPR30 oil btw), but the temperate was ok, so on a worked street motor that will see some hard driving (like track days, and serious sunday runs, lke me, kev and the crew have )i would probably stick a cooler on it, just to be safe..... Although mini's run hottest usually in traffic, and i doubt a cooler with do much good then, without any air rushing through it, what im saying aswell is coolers wont fix an inadequate cooling system

Sounds like your motor doesn't really warrant a cooler, and as mentioned it could be considered a little insane to put a second hand cooler on your fresh 1275, there is no way to recondition coolers aside from flushing them out... The risk isn't worth the benefit in my opinion

But thats all this is. my experiences and opinions

An oil cooler will NOT make the motor run any cooler, in traffic anyhow. If I didn't run mine at the track I'd probably take it off.

But IMO the best thing you can add to a big bore road motor is a heater matrix of some sort under the hood.

I had an original `68 Cooper S- I know what it's like sitting in the 40C traffic with the gauge heading north and the heater in the car on full, as it sez in the handbook...

In 9 years now with a MiniMatic box under hood, my current 1310's never got too hot, at all.

What about in traffic - surely the matic heater would have limited effect when you're not moving?

Oh the cooler is new old stock, not second hand (ie. never been used). It looks like clean shiny metal inside...

Naah i won't be fitting it in the 1100. Besides it makes a nice shelf item and good conversational topic when friends come around "cool what's that?"

It adds another litre or two to the system. Lack of water is one of the Mini's perennial problems. Anyhow it works... BMC said the heater MUST be used on all MiniMatics (they were hard to keep cool)

My van used to run hot until I fitted a clubman heater matrix behind the grille, just above the starter. It fits very neatly there.

Hot water goes through this matrix and then in to the cabin heater (Mini MkIII under-dash type). In winter I remove the grille and blank off the undebonnet matrix with a piece of aluminium, so the heater inside is more effective.

My oil pressure is normally 50psi at idle, and 70-75 on the move. But I have noticed in summer it drops to 25-30psi at idle and 50psi on the move. Not dangerously low, but a little worrying...

The Moke's A+ 1275 Auto came with cut-off oil cooler hoses. I found out the Metro donor had an oil cooler ex factory. Never seen a Mini Matic or 1100/1300 Auto with a cooler, but figure I will need one if the factory fitted one. Maybe a 13 row S one will be good enough?

I had 2- 1300 autos, no cooler, no need.
But, the MiniMatics all had a fresh air heater fitted stock, both the Leyland workshop manual and `69 drivers handbook say don't take it out!!

I don't think it's the oil that gets hot, but the motor- you've got your right foot up it all the time!

Maybe the later Autos needed one, why else would the factory fit one??

Found this on e-Bay, its the right one for my motor:

But I guess I can find something similar sized here in Oz.

50 at idle at normal operating temp - isnt it way too high?
