Where can I get a lightened stock sized crank pulley? I need to change my belts...so I might as well upgrade the pulley.

Also, I'm going to have about 1200w RMS to my sound system through two crazy amps w/ 1F Capacitor. Can I use a UDP? Can ppl with sound systems chime in and tell me what kind of system they have and do you headlights dim?

My car was recalled and I got the new alternator if that helps any.

 

You can get the pulleys from www.stillen.com or www.customenterprise.com. Also for the helping of your lights dimming you might wanna get a ground kit. You can get them just about anywhere.

 

how come on two diff brands the diff colors have been disscontinued how

And here is the underdriven crank pulley. Ultra S

Give me a call to order and get an additional 5% off!

 

why did they get rid of the other colors steve

 

At least a month and a half ago UR stopped offering the colors and they didn't have hardly any of the colors in stock for Maximas.

 

is there a reason for that?

 

Darn....I was hoping I could get one for 70 or 90 just like the motostorm one. I guess only UR makes the lighten stock sized one.

Is having a sound system that draws 1200w RMS too powerful for any UDP?

 

Your crank pulley has nothing to do with how many watts your stereo will produce. Your battery and alternator will.

 

I meant will my lights dim? An underdrive pulley will affect how many watts my stereo will produce.

If my alternator is going to spin slower due to an underdrive pulley, then the voltage of my battery will be lower. Voltage to your amp dictates how many watts are getting pumped to you speaker.

 

if you go with that UR it won't change since you are going with a light "stock" size pulley.. you won't be changing the size at all, its just going to be light....


altho they have changed the pulley on the 3.5 to a smaller one and the electrical system didn't loose any power..

 

Sorry for not being clear.

Can I run my 1200w RMS sound system with an UNDERDRIVE pulley?
Will I have major light dimming or driveability problems?

I would love to buy the UDP STOCK SIZED lightened one, but it's $180+. I want to know if I could get by with a $90 motostorm UNDERDRIVE pulley or is there any reliable STOCK SIZED lightened pulley I could get for under $100.

 

like I said...... it would only spin slower if you get a smaller size than OEM.. your power won't decrease if you get a light stock size one...

you are more likely to drop power with a smaller pulley. but like stated below they have done it to the 3.5 liter engines and even with a smaller pulley, nothing changed....



anyways, there are other ways to eliminate this dimming prob.... its called THE BIG 3 look around..

 

Yes, your lights will dim. I have an UDP and a modest system of ~ 150wrms and they dim. Also, I have the cold weather package alternator which is rated a little higher. I am debating trying to find a smaller alt pulley or buying one of the lightened stock-size crank pulleys. Check this link out http://www.motorvate.ca/mvp.php/521

 

try and get this done:

About how many hp would a Unorthodox stock sized pulley would give us??

 

Thanks for the helpful link!

So, an underdrive pulley is out of the question with my sound system. I wish someone made a cheaper STOCK SIZED LIGHTENED PULLEY.


Great link!

I know my car is 98 and yours is a 04...but was it hard for you to do?

 

i second that... u shouldnt be dimming... i have a 750watt bazooka mono amp and a 1000watt sony xplod 15" and i have no dimming.

 

nope. one bolt off, put the wires together.. bolt on, run the bigger gauge wire to the positive on the batt, all set....
