Under cowl A/C unit design input thread and gauging interest, replacing behr with burrr! Options

[Chris914n6]

Dusted off another one of my projects from when I first built my waterpumper. Heater and A/C replacing the factory fresh air blower unit.

History. I built the unit using a tube/fin core from my Uncle's buddy Dave @ Hotrod Air. HRA went under in the recession and so did the company that actually made the cores. Oddly enough this is a benefit despite having made some really nice wood vacuum forming bucks.

The good news. For version 2 I went with separate heater and evap cores. The heater is off the shelf, I just need to trim the tubes. The evap I'm having made by a company I met at the 2013 SEMA show and is modern plate type. Blower is a 3 speed.

The nitty gritty. Uses stock controls and stock air deflector boxes. Hoses run Pass side like DPD/VPC. I did design a setup for modern controls and deflector boxes with a separate side vent path, but it's a bit complicated to make.

I have plans to offer 3 versions.

Model B - A/C and heat for us waterpumpers. Runs recirc through the heater tube holes so no cutting. Unit is too tight of a fit for fresh air. I'll have an optional drainage piece for those that don't seal the grill.

Model A - A/C only for aircooled cars. Because the heater tube holes are being used for heat, air intake will be from the grill opening. You could cut a 2.5" hole in the cowl for recirc instead if you wanted or use just one heat exchanger.

Model H - Heater only for waterpumpers. Same unit as the A/C only except that recirc is possible through the heater hose holes OR model B with no evap, haven't decided yet.

In the kit - Main unit, mounting brackets, air hoses & clamps, blower wiring, expansion valve, instructions.

Options - Cabin filter. Grill water drain.

The other pieces...
Condensers- it depends on the radiator you using and what you can make fit, no point in me trying to keep an inventory. The exception could be a replacement to the DPD/VPC Condenser unit for air-cooled cars, I haven't gotten past doodles yet.
Receiver-driers of the universal type can be had on Ebay for under $15 shipped, I'll pick one out for you, same with the pressure switch.
Hoses, too many variations and too much overhead for me, but Vegas has 3 places that will build them on your car so I assume that's practically everywhere. Prices trend $100-$150.
Hard lines- Research has spec'd it as 6063 aluminum. DPD/VPC used hard lines along the rocker and up the wheel wells.
Heater hose- nothing special about it but it's long and 5/8"ID.

Prices... about the same as the Hotrod kits. Manufacturing time is unknown and the biggest factor of course.

I will have to buy 50+ evap cores to make this happen, so even if you are a year or more away from buying one speak up.

Any feedback and who wants one?
