Update, New Radiator arrived today from GPI Racing in Holland. Ordered on Tuesday arrived on Friday, cost £165 with free postage.
Overall dimensions and mounting brackets are very similar to the Docking so it will be an easy replacement, slightly smaller, with an extra bleed tapping and a couple of extra bottom lugs which I may want to cut off.
Weight wise, the Docking is 4.6kg versus 3.8kg for the gpi.
The first picture shows them side by side, and the pipes at the same position relative to the top, there is extra angled tanking on the bottom of the docking, where the GIP is flat, that must be at least in part a source of the extra weight.
Quality looks robust, welding looks good, polished side tanks, and powder coated top and bottom covers and lugs.
Second picture shows the tubes for the GPI radiator, and third, the Docking. Although the thickness of the matrix is the same, about 40mm , 1.575 in, the GPI has two tube rows, compared with the Dockings' one, so the flow resistance is probably higher on the GPI with a lower cooling capacity. Now before I fitted the electric pump, the cooling flow was abysmal, and the gauge from the engine block sensor was 90C plus Currently the block reading has been 65C to 75C with a radiator inlet of 85C, so I am not too concerned if the electric pump has to work a bit harder. I will report back once I have it fitted and up and running.
btw, in pic 3, those are the leaking tubes in the Docking, but no corrosion and no obvious sign of why.
