    Supergill radiator

    You have probably heard of my Supergill radiator for the Stag, this was developed by me back in the late 70’s, over the past few years some companies and traders have been advertising Supergill radiators, they are NOT my Supergill radiators, I have had several conversations with unhappy Stag owners that have bought a so called Supergill radiator and found it to be no better than the old radiator, and in some cases worse than the one they have removed. I have now register Supergill Radiator as a trade mark to try and stop companies and traders from misleading their customers. The only people that can sell and fit my Supergill radiators are myself and Enginuity in Acton.

    Would you care to explain what is special about them?

    (I know), but it's quite possible many people don't.
    The secret is in the core design and the actual internal surface area exposed to the water.

      From what Tony has said, the Supergill radiator I was sold by a Stag Specialist is not one of his. I bought it a few years ago and was told it was a Supergill radiator. Might dig out my old receipts and see what that says.

        The difference is in the core construction, some radiator remanufacturing companies try to fit as many cooling tubes as they can, net result is smaller tubes, restricting water flow through the radiator and as the tubes are closer together this restricts airflow, my Supergill radiator core has cooling tubes that allow belter flow of coolant and in line not staggered, staggered cooling tubes can restrict air flow, the cooling fins around the tubes are a concertina design not straight up and down, this allows better air flow, the spacing of the cooling tubes is also slightly different allowing better air flow through the core, the core is about 20% more efficient than the original standard core.

        There are some core manufacturers that make cores of a similar design, they are not the same as my Supergill core.

        The reason I developed this core back in the late 70’s was that a good majority of my customers were based in London, my garage was based in Fulham, traveling across London on a hot summers day in heavy traffic would cause the engine to run hotter than you would like, and worse on late Stags with the square side tanks. My late brother bought a new Stag in 1977 and it ran very hot in heavy traffic in central London, he went into the BL dealers on the A40 in Acton and explained it ran hotter that was healthy and asked if he could fit one of my Supergill radiators, they said no it would invalidate the warranty, he asked them what would happen if the engine overheated and caused damage, he was told, that’s not a problem, we would fit a new engine for you under warranty. And we wonder why BL had so many problems.

        The standard original core was fine and did the job under most conditions but sit in a traffic jam on a hot day and the temperature would rise, sometimes to an uncomfortable lever.

          Thanks for the explanation.
          That is highly informative.

          Would you care to comment on the relative efficiency of the latest all alloy designs?

          Copper conducts heat better than aluminium (and electricity by the way....).

          Most modern car radiators are made out of a mixture of aluminium and plastic.

          Why do you choose copper for yours?

              Probably best I don't comment on the alloy radiators, you said it all.

                I bought a supergill radiator in 1981 for my 1978 Stag. It cost £120 + VAT then.
