Yeah thanks figjam, I forgot to say that too. I looked at your chart and my outside temp was i think 87 F and humidity was like 36%. it's the optimal condition for a evap cooler. i converted those numbers for 110 degrees F and 10% humidity like you said and I got a 25 degree difference. so if we had...

I just made the mods you guys said. i added a second layer of pading and I fixed it so there is a gap. i had to sew up the seams to made it hold together and i even sewed the tubing so it stays centered. i'm getting a about 13 Farenheit difference now. so I actually lost 10-15% efficiency over what ...

oh right, my question is how were you able to acheive a 30 degree farenheit difference?

FIGJAM your pump's specs says I think, 87 gallons per minute at 9 volts, so ...thats about 110 gallon per minute if its 12 volts? my pump is rated at 42 gallons per minute, but i used the battery so maybe ...40-i have no idea gpm. anyways your pump sounds like its over twice the flow so maybe thats ...

I just stated test results.

no that was directed to the other 2 guys who said it leaks, not you

FIGJAM I used kawasaki titanium drill bits. I used a 5/64th inch bit, its tiny and the holes are super clean. but i'm also using vinly tubing. I'm gonna buy that thermometer you have and test it. I don't think I could have made this wrong, I'll get pictures later.

I found out why it "doesn't leak" . when the pad is completely dry it leaks for about 5 seconds, you lose like a spoonful or 2 of water then it doesnt leak any more. the water was leaking from the TOP of the holes then when the pad was soaked the wicking action stops the leak, going against gravity....

Your pads are touching the sides of the bucket at the holes. It's gonna leak! :roll: But it's an improvement. :shock: Not even a little bit. :lol: There's a lot of missinformation, and I don't intend to rewrite or correct it all. :roll: Hey FIGJAM, thanks for posting. yes please give me some insigh...

First off, I wouldnt call that an improvement, just a different way of doing it. As Figjam said Its going to leak with your foam against the holes and the inside of your car will get wet. Before trying to make something better than the original, you should make the original and see how it works. I ...

... My initial intention was to use a tarp and funnel this thing through the car window, but I think I’ll just have it inside the car. It’s hot as hell already and this isn’t as cold as the car AC so I’m gonna keep it on the passenger window aims inches from my face. ... I'm not understanding this....

I did get a leak when I did initial testing inside the house, but surprisingly I took it and set it on the concrete ouside the car, plugged it into the car 12volt and ....it doesn't leak

The CFM numbers are different from the $30 fan to the $4 fan. it's not though I kept checking and they all say abf1212she-xxx , with xxx being some different number, but all the fan models I saw said 151cfm or something within 1 or 2 cfm of that. so unless I'm missing something, they are all the sa...
