Got bored today and started fabrication on all the components of the liquid intercooler and chiller for the turbo. Others have stated from 50-75% reduction in temperature using the chiller setup. Front you can see the additional radiator (precooler), on the left is where the chiller will sit (powered by an additional A/C core) and on the right you can see the intercooler exchanger (just outside the fenderwell on the driver's side).
Routing will start at the chiller, pass through the intercooler core, then through the radiator for precooling again, then back into the chiller. If you would like to use a similar setup without an A/C core, you can set up a barrel (like a one-gallon bucket for example) with a ice/water/salt combo with a submerged oil cooler core inside.
Current concerns are that by running the A/C in advance of (not during) the race may cause condensation to drip and get expelled from the staging line
The following image is a mock-up before final install to make sure everything sets where I want it and all the lines can be routed where I need. If you'll note, the radiator is mounted forward of the cross brace to give ample room for the dual 2" fans behind it, and also so it does not sit directly into contact with a 200 degree engine coolant radiator.
