Here's the basis for my future A/C system for the MGB:
IMG_0035.JPG
It is the evaporator out of a VW Vanogen

Here it is in place in a '74-1/2, not the car it is to be used in but a good test for fit.

It is positioned above the cowl vent door but the wiper mechanism and windshield vents may pose a challenge

The dashboard will have to be positioned closer to the driver.

I won't be able to start on this for awhile, but I bought these parts so I can run the under-hood lines back to the firewall.

Holly crap Jim, are you looking to freeze steaks in that thing!!!
One of the biggest challenges will be to find space for all of the plumbing and wiring, but I'm sure you'll be able to figure it out no prob!

If I can ever get around to restoring my C-GT, I would like to add A/C and electric power steering to it.

I think the condenser is about 28 x 16" and around 7/8" thick. The pump is a large displacement Sanden. Evap should be big enough not to freeze up I hope. Got a 2 ton TXV on it.

Well you know, it is a convertible after all. Takes a lot of capacity to A/C the outdoors. But I do have some experience, I once worked in a hot shop in the summer where I took a room A/C unit, mounted it on a cart, rolled it up to my work station and plugged it in. Got a few funny looks for that one but I really didn't care.

Jim, have you explored mounting the evap. in the trunk and running duct to the front, or maybe using two (2) evaps. one for each side. The controls for two evaps already in use on today cars.

Agreed Carl, but mounted on the hood like that it's only going to benefit the guy behind him!
On the other hand it's big enough that I should be able to feel it up here.

Live like you mean it.

No, no no. You guys have got it all wrong. Didn't I say it was for my roadster? Not the Chump car. Not the trunk. Not the hood. Sheesh, you bunch are hopeless. Bunch a senile old...

Look it's very simple. Maximum overkill in the allowable space. Simply yank out the dash, throw all that away and there's plenty of room for A/C. What could be easier?

No! That was just for the picture! It can't go in the Chump car, that would just slow it down! In fact we should probably get rid of some weight. Do we really need that part of the body? We'll have a cage right? Maybe we can just chop out that part and toss it. And all that bodywork on the off side of the car, what's any of that doing for us? We can throw away that too, right?

It would speed it up with all that cool air blasting towards the back of the car!

Well, the under-hood work is complete. The suction run was kept short outside but will cross the dash inside where the more heat it absorbs the better.
IMG_0001.JPG
adequate pulley clearance was found by using a "reduced diameter" hose for the high pressure line
IMG_0002.JPG
The dryer was tucked in tightly against the liquid separator for the intercooler system.
IMG_0003.JPG
And the liquid line was kept short inside but is run low outside where the more heat it sheds the better.

The evaporator and dash will be a winter project, and maybe not this winter either. Lots of planning is required for that one.

Looking good Jim. Others may have different experience, but I've found AC to be useless with the soft top. So much hot air pours in around the door glass that on a 95-100 day, the cockpit is still in the upper 80's whenever I'm going about 25-30 mph or higher. That's why I got a hard top for the heat of the summer around here... But, I find I prefer the top down and only use the AC & hard top when my wife is with me.

All I want is a big vent that blows cold air in my face.

Jim, Rob agree cooling a soft top like ours is like running a warm morning stove inside the frig. Both work real hard and get very little done.

Like Jim wrote, all I want is a cool breeze in my face and maybe in the foot wells.

Does it need to be in the dash? Can you run the lines behind the seats and mount it in back?
