A/C delete

Putting a cage in the car this winter and while I have the rear clam off going to pull the front and do the radiator change and some other things. Im adding some weight with the cage so need to remove some too! Posted this on FB but there does not seem to be to many mechanically inclined people there. BOE Phil as usual can always be counted on for some helpful advice. He suggested pulling the whole HVAC system and gave me some advice on the belt however it dawned on me I live in the South. The always jungle humid south, and while I may not need heat, I need defrost or defog in this case almost every day, especially when the car has sat in the paddock all night uncovered. Did several searches and came up with a few threads that had minor info. Maybe some other track junkies will have some advice.

Want to remove A/C parts only from a 2007 Exige S.

What specific parts do I need to remove and what do I leave in?
What will this do to the radiator fans? Will it see the A/C on with everything removed and constantly run the fans? Can I or will I need to jumper it?
Know I need to change the belt, does anyone know of a source or part number for a stock SC Exige?
Did anyone learn some good tips or tricks from doing this?
Any good write ups on front clam removal on PDF out there? Everything I have found so far is for an Elise.

Thank you.............

Using A/C is the best way to defog a car... loads quicker than heat. While you will save some weight taking it out you might lose more functionality than you want.

True and thanks for the input!

Its a track only car that im not admitting is a track car. The AC is the last stronghold!

AC has not been used in 3 years and I have time to let it run and defog at the track. Wish it was like aircraft windows and have a heating laminate!

Thank bro!

Do you have the HVAC section of the shop manual? If you don't, you need to get it and study it. Learn how the system works and then remove what you can. You won't be able to remove the AC lines from the passenger door sill areas but you can get most everything else.

I removed the compressor, rear lines, front lines, condenser, and dryer. You will not have a factory location to mount the radiator fans because they are attached to the condenser so you'll have to fab up some brackets. Should be easy. The fans will still function as normal.

After all these years, there is no tutorial for the AC delete on our cars anywhere that I've found (including thelotusforums.com). We have some threads with good tips, but no step-by-step. Gunpilot, I see you helping out the community real soon.

You could delete the heater core and airbags while you're at it. Definitely hold onto these parts for a re-install if you ever sell years from now.

I know Phil has had several clients request it. I'm definetly flying blind on this one. Planning on deleting the passenger airbag, drivers is gone already. Have to make up weight for the cage install. Going to leave the heater core in mainly for defog. It's very humid down here.

I know when my mechanic was telling me how much weight could be saved with the AC delete he also stated that with the AC removed the battery could be relocated to the front and the heavy cabling could also be removed. Something to consider.

I could also leave some of it in place for Kill Switch wiring too!

I think the whole point is that with the AC out of the way the battery goes up front and the heavy cabling that ran from the front fuse area to the rear battery is eliminated. I can't comment on how thick the kill switch wiring needs to be but I would think it would connect in the front of the car given the above scenario.

If you move the battery to the front of the car you still need the heavy cable running to the back for the starter motor.
