Chill out with CSF.

If I don’t keep to my monthly “to do” lists, I would be all over the place with projects. I wanted to focus on the radiator, oil cooler, and core support in March.

First on the list was to mount my CSF R1 Competition Radiator. If you follow time attack racing or road racing, you will notice a huge hood outlet(s) on some of the cars. The reason is to add down force to the front of the car. I’ll be running a pretty big wing and diffuser on the rear. A front splitter and canards won’t be enough to balance out the rear. So I’ll be ducting air flow thought the radiator and out of the hood to create down force. The GT2 Corvette below is a good example of how it works.Imported from MIFF image: 35656641.X

I needed to build a core support that I could hang the huge CSF triple bypass radiator and the oil cooler on. So I rolled out my trusty 150HD bender and slipped on the 1″ bending dies.DSC02468

A few tricky bends later, I finally came up with with the core support that I envisioned.DSC02282

I wanted to make the core support easy to remove, so I created these interlocking mounts on top.DSC02470

To secure the core support to frame rails, I fabricated my own mounts and used 1/2″ allen bolts to secure it.DSC02471

It was pretty simple to mount the oil cooler with pre-fabricated “trick” tabs.DSC02476DSC02284.JPG

The CSF R1 Competition Radiator is made for serious race applications. I fully expected to have to modify it considering I’ll be angling it. The radiator came with some really thick AN fittings for fluid inlet and outlet, but the chassis was fighting for the same real-estate. To keep the car simple, I decided to run more conventional hoses. This meant that I needed to cut off the AN fittings, cap them, and weld on new aluminum ports.DSC02386


Mounting the radiator was very easy. CSF gives you plenty of room to mount your radiator. I wanted to isolate vibrations to the radiator, so I ordered up these high temp 1/4-20 isolated studs.DSC02371

The hood is going to fit pretty close to the radiator, so I wanted to give the radiator some breathing room. I sunk the mounting points in the front of the core support to retain as much room as I could.DSC02390

When I originally ordered my CRS Performance billet aluminum thermostat housing, I ordered the wrong outlet. So I shelved the 1.25″ inlet and installed the 1.5″ intlet.DSC02477

The next project is to plum the radiator and oil cooler, then eventually make a shroud for the fans. You will notice the radiator does not have a radiator cap. In most racing applications, the radiator is going to be in a odd location. A perfect example is pro drifting. It’s pretty common to angle mount them in the rear of the car. Since the radiator sits lower than the water pump in the Z, I’ll need to run an expansion tank. That’s all kinds of witchcraft that I’ll get into later.DSC02399
