Direct bolt on. Just a little bit of problem measuring for the new belt. And taking the damn alternator off. I'm very happy with it. I'll post pics as soon as my camera is back in my hands.

You can pick this up at autopartsperformce.com. Total came out to $53.50 shipped.

 

Do the lights dim at night (or even in the day) at stop signs since the smaller pulley isn't able to toss out more juice?

 

It's an oversized pulley and the lights stay the same.

 

does it add hp

 

was it alot of problems installing

 

Guestamating 3-5hp gain, and no it wasn't hard to install.

 

I tried that website but I got an error.

 

driverfx.com also has it but you will pay like $5 more for shipping.

 

Don't get the pulley, severe belt slippage. I took it off and adjusted it, same slippage. Returning mine tomorrow.

 

Why would a Alt. Pully add hp?

 

I was wonderin how that works as well

 

Any pulley in the car whether it be the accessory pulley, alternator pulley, etc, takes power from the crank to spin. That's power from the crank that could be spinning other things...like say...the wheels perhaps? So you're reducing functional loss by either lightening the pulley or making it smaller.

 

You reduce the amount of power wasted on accessories such as AC, ALT, or PS, when the replacement pully is LARGER (not smaller) than the original. The larger pulley means that the accessory in question spins at a rate LESS than stock. Hence the term "underdrive."

Just think of the diameter of the crank pulley vs the one on whatever accessory you're looking at. Small pulley on alternator means it spins faster than the crankshaft so the car can generate sufficient current, especially at idle.

Don't screw with pulleys. There was another thread out there and even ROCK said he's not a fan of them.

 

Freakin' leverage *slaps self*

 

im installing my Moroso pulley tomorrow... ill let you know how it turns out
