A/C and AIR system removal

Well, my a/c has never worked, and the engine bay was so cluttered i couldt even change spark plugs. Plus i live in western washington where we get mainly rain and clouds. Id say it dropped probably around 40 pounds off the front end of the car. Im not sure if it made any HP gains, it was on one belt as opposed to the 4th gens whos a/c is on a seperate belt, I guess the previous owner installed a custom a/c kit that uses the stock thirdgen a/c components. One thing i did notice is i used to have a thumping noise when the car would run, now its gone, must of been something to do with the a/c.

So here is what i did.....

First i went to the junk yard and found a NON-A/c car, took the heater box from the firewall out of it. It made ALOT more room under the hood.

then i removed all the lines and canister.

then yesterday i removed the condensor(?) which was easier than i thought it would be. Im very happy with the results and am going to change spark plugs today lol.

I also removed the AIR system when i did my header install.

Before


After


Im thinking of getting some corvette fuel rail covers now to clean it up even more.

I've been wanting to do this forever. You're the 10th person to tell me it will take off 25-50 pounds depending on how much of the actual AC system you remove.

How long did it take you? Did you need to get a shorter belt?

well, I did need a shorter belt because my A/c was on the same belt as the everything else, so i asked around on ls1tech about what size belt i would need for a stock ls1 with a 25% underdrive pulley (since 4th gen ls1's a/c is on a seperate belt.) ordered the belt for like $30, went to the junkyard and got the non ac heater box for the firewall for $25.

took it home, painted it.

the removal and install of the firewall piece was the hardest, it has like 5 bolts, a couple you have to peal the carpet back from the pass floor and take them off there, the others are from under the hood, the hardest is one next to the heater hose, i removed the heater hose to make it easier and put it back on when i was done.

then i took all the lines and fittings and the canister, make sure you have it properly drained or you know for a fact it IS drained. this step was very easy.

then the main head unit, condensor, i thought it would be harder, i just unbolted everything and put the pulley in the place of one of the rollers, pulled the tentioner down and it just went right together, seems like it idles smoother and and doesnt make the thumping noise that it used to, not sure on the weight reduction, but ill be weighing the car on the way to the drag strip next sat, im thinking 3100.

I'm always on the look out for the A/C delete box but can't find one. Anymore in the junkyard that you go to?

Removed the rest of mine over winter, ive had the compressor off for three years tho. I just used a delete pulley in place of it. Then i made my own box out of sheet metal.
