i saw pullys for our cars and does any one have them and what kind of gains did they get and it is worth the money???????

 

Here's you go.

 

I have the Racing Beat set the dual Alt and Main. You can kinda fell a difference in acceleration but not much. Is it worth it? I say yeah why not.

 

a slower water pump will not cavitate because of high speed, and the water has more time to pick up heat and carry it to the radiator. the pump and alt bearings will last longer. power increase ? not much but alot of little bits add up. down side= alt output is down ,so hook up a battery tender each night .

 

Or use an Optima red top

 

I have the ones from http://www.revolutionrotary.com/

Under Driven Polished Billet Aluminum Pulley Set.

I like the way they look, work great with electric fan setup... runs much better, I felt a little more pickup.. but that's me I'm not sure if it was because of the pulleys or not....

I'm happy with them....

If you want to see them on my car go to http://www.rotaryrx7.com under my rx7 link.....
