After the motor was installed with the balancer in place the BeCool unit was mocked-up in the final rolled forward position. Templates for brackets were cut and transferred to aluminum plate, which were cut, drilled and welded to the side tanks of the radiator.
The brackets were drilled for mounting holes that allowed them to bolt to the frame rail. Nutserts were drilled and installed into the frame rails for these mounting bolts, shown below. These initial mounts are bolted directly to the frame but about 1" of room was left to add some isolators. We will do this when we build the ducting, as well as possibly add a secondary set of mounts at the top and/or bottom.
More calculations were done and the slimmest, highest flowing pair of fans that covered the most area of the core were ordered.
These Mishimoto Slim 12" electric fans (MMFAN-12) each flow 1150 cfm. A bracket was built along the top and bottom to mount them close to the radiator core. There are more powerful fans in 12" but they were all thicker and could run into parts of the engine.
Some custom radiator hoses were built from HPS silicone hose bends and some mandrel bent and straight aluminum tubing. The front of the radiator core will be ducted to the gill openings at the front and to the hood opening behind it - we will show this later in the build.
WANGIMUS MAXIMUS
"Big Downforce" is part of the "Bigger is Better" mentality we are applying to many aspects of this build. Of course a giant rear wing was ordered from AJ Hartman Aero - a full 72" wide and with his longest 14" cord.
We have installed plenty of rear wings but on a car that could see speeds in excess of 180 mph, it needed to be a bit overbuilt.
After deciding where the uprights would be (and thus the under-mount saddles) we ordered the wing. When it was delivered we played with mounting locations, getting the element where it could "do the most work" - way up high and far back - then Ryan made cardboard mock-ups, which progressed into plate aluminum versions. We had thought about a bent upright, but that was quickly abandoned in mock-up.
We settled on this flat design that would be gripped with a steel U-shaped lower bracket, that could then be bolted to the trunk.
