Radiator mounting

Seeing as this is a high-power car which will see track time, the cooling infrastructure needed to be updated. The radiator which I chose is considerably larger than the factory radiator, and the stock radiator mounts were removed to make clearance for the drivetrain to conveniently go in and out of the engine bay. Some new radiator mounts needed to be made. The design which I chose for the new mounts is simple, light, and very strong. The lower mounts, that the base of the radiator slips into, are much stronger than radiator mounts need to be. The mounts are overbuilt because they will double as mounting points for a belly pan and splitter. Once I dive into aerodynamics, this car will likely end up with a splitter capable of generating considerable downforce. The splitter and belly pan also need to be strong enough to not deform under small impacts. i.e. the car bottoming out over a tall speed bump or steep driveway. My lower radiator mounts should be more than up to the task.

These are the lower mounts. 1″ diameter 1/16″ wall steel tubing runs down from the frame rails and is held securely in position by gussets. The pockets were made from sheet metal.

This view is looking in from the opening in the front bumper. Sheet metal was used to create a surface for the radiator to lean against and more of that same material was used to triangulate those surfaces to the frame rails, adding significant strength.

Rubber bumpers were later installed on all of the mounts to isolate the radiator from potentially harmful vibrations. The radiator is slanted for three reasons. The first two are so that the mass of the radiator can be lower and further back. The last and perhaps most important reason is to create clearance for an air intake pipe to pass from the throttle body to the front bumper without having to cut a hole in the hood or use a smushed pipe.

What you have seen up until now allows the radiator to conveniently slide in and out of the car for the sake of easy serviceability. The radiator is also held in place by what are essentially L brackets that bolt into the frame rails and apply enough pressure to the back of the radiator to hold it securely.
