I am having a problem figuring out the theoretical heat the xflow can dissipate the website states rated for 1732.5 KCal per hour.

Well, which model, and what are you looking for, heat in terms of watts?

Black Ice XFlow 3 (3 120mm fans)
On the site it has the kCal number stated above...I have figured it out but it doesn't seem right. And yes...heat dissipation in watts.

Yeah those conversions are a pain in the butt. Trying to find one that will do calries to watts. Everything wants to go to joules.

I estimate it can only cool like 180-210 or so watts...I may be wrong in my guesstimation.
I am cooling a Q6600 with 1.375v and at 3.33Ghz...I estimate that to be around top end for this 3x radiator (i am only using 2 fans...no shroud...each with around 65cfm)...am I wrong in these calculations? I used the innovatek heat output for my B3 and it says at max I could be producing 165w of heat.

There is no way this thing can cool 2,000 watts...that would be better than the Thermochill PA120.3

Well, using the number you gave above.
(1732.5)(kcal/h) x (4.184)(J/cal) x (1/3600)(h/s) = 2.01355 (kJ/s) = 2013.55 W
(1732.5)(kcal/h) x (4.184)(J/cal) x (1/3600)(h/s) = 2.01355 (kJ/s) = 2013.55 W

My brain hates math today.
But you also have to consider at what kind of air flow is that measured at? Is that just passive? If they strap 3 deltas or panaflos to it, and start cranking 400+ cfm through it, and then measur eit, yeah you get a big number.
It's still a damn good radiator.

I agree, 2000 watts sounds ridiculous. It is possible that the number is a complete lie. More likely though, is that it was calculated from the surface area and thermal conductivity of the materials used. The amount of heat transfer depends greatly on airflow, coolant velocity and the temperature delta between the coolant, the radiator, and the air passing over it. If the temp difference between the coolant and the air was a hundred degrees, dumping 2000 watts of heat wouldn't be a big deal. However, when its only a few degrees, the numbers fall pretty quickly.
Making a calculation for the heat transfer of a PC radiator using only thermodynamics is pretty much pointless. There are too many variations between installations to come up with a number that is useful.

Couldn't have said it better. That's why all the side by side comparisons are so invaluable. They can actually give you a real world picture.
@ OP
I REALLY wouldn't worry about your radiator being able to handle the heat ouput though.

A single pass radiator is not the greatest...as I have learned since I began watercooling a few weeks ago 
When I add my graphics card to the mix...I think I will be pushing my limits with this. Also the radiator is extremely restrictive when it comes to airflow. I think I am going to purchase the Swiftech MCR320-QP and radbox (for mounting) just to quiet this thing. I wanted to go water for cooling and quietness
