cliff notes: underdrive pulleys and black magic fans are poo poo.

i used to have a difficult time driving my car to work. i drive 30 miles one way (about an hour) and during the warmer months, which here in florida accounts for about 10 out of the 12 months, my car would run very warm.

without the a/c on she would run about 190-200. with the a/c on... well, i'd have to shut the a/c off when she hit 215 or so. that was usually about half way home. that sucks.

so our first purchase was a high flow water pump. didn't help.

our next purchase was an upgraded flex-a-lite black magic fan... the black magic extreme. didn't work.

i was left sweating in my car and scratching my head. i was not happy.

so we decided to go back to square one. i have underdrive pulleys on my car. we designed the turbo kit with them on. john decided to put the stock pulleys back on the car to speed the water pump back up. well we couldn't get the stock crank pulley back on because of the down tube, so we settled for just putting the stock water pump pulley back on.

then john did a test on the black magic extreme fan. he took the radiator and fan assembly out and put it to the paper test. we were actually disappointed to see how weak the pull of this fan was; how close the paper had to be before the fan would suck it up. and the pull was almost non-existent on the outer edges of the radiator.

john got an idea about dual fans. so we bought regular old summit brand dual 11" fans and installed them. we did the paper test with these fans as well and they pulled the paper in from farther away and the pull was almost as strong around the edges of the radiator.

the results? the other day i drove her to work and the weather ended up being 96 for the high and on the way home in late afternoon traffic with my a/c on she got up to 188 degrees at the hottest.

now thats what i'm talkin about!
