Wow, thanks a lot. Mesh is a question - it will stop garbage, but it also loses pressure significantly at high speed.
About radiator, I got it. I have a feeling that it makes sense to remove radiator from condenser and put it horizontally on top of the box. Since it's large it can work with just a static pressure of air. But that allows to give more cool air to condenser. Considering that they already running compressor on overdrive, I believe it's way more important to cool down condenser, so less restrictions at input and output and no front heaters.
Condenser is hotter and therefore better heat exchanger than radiator.
Another problem, though, that top opening going to lose static pressure, so flow through condenser might drop. Anyway, keep us informed - it's very worthy project.I t's great MPP is working on that. I am a supporter of stock look, so I hope we won't need bumper drilling
