was in the market for some light weight pulleys . jus wanted to know if they really serve a purpose power wise??????

I haven't used one, but this article mentions some hazards:

As for the crank pulley, stay away from them unless they are dampened. As for the others, they are far lighter than the stock pulley's, and thus lower rotating mass and in theory COULD make a difference, but nothing that your going to feel.

waste of money...the gain in hp is damn near non existant....

i have one siting on my desk gathering dust.

You're not going to pick up any noticeable power with pulleys. Mentioned earlier, don't not replace the crank pulley without out a dampened one; the motor will tear itself apart.

You save 1-2hp per pulley, they are more for look.

There won't be much of a hp gain but throttle response would be a little better.

Is there a company that makes a full kit, with a HB?

Unorthodox Racing makes the pulley set for the 2J; Water pump, Alternator, and Power steering. Also, as some have stated the Crank pulley needs to be a Dampening one so please don't put the Unorthodox Racing Crank pulley on.

save your money and use it on something else
