For sure, thanx to you both, then If the pump adds anything substaintial (in addition to the UDP install), I may have to treat myself to one for the holidays (pick one).

 

My car has the Shaker 1000 system in it. I would doubt that it draws nearly the power that 1 or 2 large amps running a couple of big subs would, but it's still a 1000+ watt setup which I am sure draws a good current to power-up.

With the headlights and fog lights on, heater running, and stereo running on the higher end of it's ability, I've not noticed any dimming of the lights or the volt gauge dipping or fluctuating, so it seems to keep up pretty well. But like I mentioned above, a "BIG" set-up probably draws a lot more current than the Shaker 1000 does.

Also, my car does have the factory Anti-Theft Alarm, which includes an upgrade to a higher-capacity battery than is standard without the alarm.

 

Another belt number is size 990K6 from autozone at a cost of around $23. That would be a Duralast belt.

I do not have numbers for the pulleys and pump together. Because of timing and my schedule when I did the pump I was not able to do a before/after on the same day and I installed 4.30's at the same time. I can tell you though it did add power that I could feel and the car did make more on the dyno. I just did not get to do a good before and after with only the pump install.

Meziere and Steeda are both top names in there industry and I wouldn't worry about quality. Because both companies are good if there ever was an issue they support what they sell on pretty much a no questions asked basis. They just fix the problem. That is why I work with both of them.

I also agree on the stereo issue. I have always told customer if you are going to set your car up with a crazy aftermarket stereo you are worried about charging dont get pulleys. If you have a stock car that is loaded it never seems to be an issue. Actually even with the stereo what you get is dimming at idle and it still charges fine when driving for the most part.

 

I was also wondering the same thing. Will someone chime in on this? I remember some threads a few months ago talking about how it UDP's are dangerous b/c the replacement crank pulley is smaller than the stock one.

I don't know much about cars so I have no idea about this.

 

Well, I can tell you that I have two Kicker KX650.4 amps in my car and my lights do not dim one bit. I also have a big azz cap that sits between the amps and the battery that has a distribution block on the top of it and digital voltage readout. At idle, with the stereo turned up to a painful volume, the amps have +12.5v going to them and no dimming at all.

But then again if you are going to run a big stereo you should have a cap in the system, just good sense.

 

My system will be around 2-2.5kw so I will probably skip the pullys.

 

I hate to hi-jack this thread, but this is the first I've heard of this. Can anyone confirm? Is that documented anywhere?

 

Since everyone is saying they are happy with their UDPs, what kind of gains are you actually getting?

 

There is a quote in the Media/Press Release Ford issues on the vehicles. It states "....and a high-capacity, 60-ampere-hour battery that sounds the alarm longer." Here is a link to the press release. The quote is on page 3 under the Safety & Security" section of the page....

Also, in the owners manual, there are 2 different batterys listed in the parts number section. They are...
Battery -- BXT-96R
Battery - (with High Electrical content) -- BXT-40R
That quote is located on Page 228 of the 2006 Owner's Manual, and here is a link to that.....

A little something extra most people don't even know they have.

 

Well that sux. This means I don't know everything. j/k

Thanks for the info, Kenny. I love learning more about my car.
