Ebay Under drive pulley install help.

[toomey200]

I just recieved my after market ebay under drive pulley. I was doing the installation and noticed that my OEM alternator belt wont get tight enough. With the new pulley is it possible that I have to buy a new smaller belt?

"under drive pulley" always requires a smaller size belt.

You HAVE to buy a smaller one since the pulley its lighter and smaller

Ok thanks... Ill go run to the store now...

instead of guessing at the store, ask the person whom sold it to you if they know what size the belt is. Otherwise if you know the size of the original pulley, the size of the new pulley and the size of the old belt, you can do some math and figure it out.

When I had an Unorthodox underdrive pulley on my old car I went to Advance. I told the guy behind the counter that I was putting on an underdrive pulley and he brought out a few belts. He told me how to read the numbers on the belt. It was pretty basic, something about the last two numbers being the length of the belt in mm (I think...). Anyway, he gave me a few to try out, and they fit perfectly.

Is this worth buying to free up some hp?

There are many other things you should do IMO. I think that the car was designed with a harmonic balancer, and the EBay underdrive pulleys most likely are not correct for our cars. Fluidampr makes a nice one.
