I know it's a bit soft but I was kind of keen to keep the a/c so that makes space at the front of the car very tight.
My current thinking is a large-ish radiator mounted flat above the gearbox with a blow through fan mounted underneath.
I have a supercharged engine cover to help fit all that in
I think I read somewhere that the air flow on adubs is from under the car, past the engine and out through the engine cover - given the shape of the car the area behind the rear window looks like it would be a low pressure area.
I would maybe need some sort of divider to separate the hot air from the turbo and manifold from the intercooler and radiator.
Actually, just had a thought - the Corolla I bought had a narrow but thick Koyorad radiator that took up just over half the width of the standard area. The turbo and wastegate sat in the empty space on the drivers side. If I could do a similar thing I could create a vacant space for the W2A heat exchanger.
Could maybe even use the radiator from the Corolla
Hmmm some serious conceptual thought is required......
