Anyone thinks their car runs cooler with the pulley change? I know there was a thread and the topic of "Cavatation" came up but with no real answers. I dont have an underdrive pulley but thinking of geting one. My thinking is in addition to the 1-2hp gain and cavatation issues might the engine run cooler because the coolant is staying in the radiator longer and able to get cooler?

 

I doubt very much that it makes much difference even if some cavitation is present with the stock pulley .

 

I have the Agency underdriven pulley and don't notice a difference

 

Thanks Guy!
^Jon316G how much city driving do you do? While in the city howz the AC? Still as cold?

 

i've got the onorthodox underdrive pullies, and to be honest all it does is add more throttle power. My AC is the same as when i drove it off the lot....

 

Mainly ~20 miles city and ~40 miles highway (work and back) and I don't notice a difference in temp going from the highway to city streets.

 

Thanks again!

 

it is a known fact that our pumps cavatate at about 6K---how much time do you spend over 6K? Up to you.

an over drive pulley only way to go

 

overdrive ?

 

I have the SR motorsports pulley set. I picked them up (at a bargain price) from someone here on the forum because he was selling his car.

After installation, I noticed absolutely no difference in anything! However, I realize that underdrive pulleys for this vehicle are a "feel good" modification and I can never seem to get enough of those.

The Agency Power underdrive pulley seems to be a favorite, go ahead and try it.
