I have the upgraded sos pump is its right bout 7gph i wana say

Meziere Water Pump

http://www.summitracing.com/parts/MEZ-WP136S

This is nearly 3x the flow as the SoS pump, but I head this pump would be overkill. Doesnt the water need enough dwell time to do its job?

Similar pump to CT/SoS

317 GPH pump (Over kill?)
http://cgi.ebay.com/ebaymotors/Bosch...Q5fAccessories

I can find these things all day... im gonna start researching dewll times and max efficiancy for the pumps and the heat exchangers. Looks like the SoS pump is the best so far.

Not sure how much engineering goes on in deciding which pump to use in terms of flow rate and the radiator size.

I have an upgraded heat exchanger already. Had it for about a year now. It's an ebay one that I got for $120 shipped. Works perfect and same size as others for hundreds more.

I will check out the Cobra one, think I had heard that recommended before actually.

I am using the Bosch pump that comes from the Ford Lightning and Mustang Cobra.

Another pump I've heard would work is http://www.johnson-pump.com/JPMarine...tion/cmco.html

So I guess this would be the one to get?

This definitely flows more than the stock vortech unit right?

Not sure which pump would provide the best conductivity and not move too much water.

Im not sure, can the upgraded SoS pump can be improved on for the upgraded heat exchanger?

Hmm im almost tempted to work it out for a given constant


To raise the temperature of 1 pound of water 1 degree F requires one BTU. If one pound of water at 62 degreesF is raised to 212 degreesF liquid, 150 BTU's would be required. When one pound of water at 212 degreesF is converted to steam, an additional 970 BTU's are absorbed. The total number of BTU's absorbed in converting one pound of water at 62degreesF to steam is 1,120 BTU's. Water weighs 8.33 pounds per gallon One gallon of water, when converted to steam, will absorb 9,330 BTU's (8.33 times 1,120)

Am I on the right path here?

But seems other conversions will be at play here to get to the final product of IATs...

I just gotta get a lazer thermometer and take before and after measurements to see what the current system yields. Take measurements of the pump rate, amount of water its pushing, IAT temps... them same measurements with the AC pump unpluged.

Then increasing the flow rates and measuring the difference should give the needed data? Am I going too far into the left field or does this seem like a decent approach.

To normalize it as much as possible, I was thinking of drving at the same intervals down the same distance during the same ambient temps.

Yea SoS's website is very deceiving. They really need to state that it does NOT come with a new water pump. I figured the complete kit would include a pump. I really paid 70 bucks more for some hoses and brackets? Their website needs to at least explain what's included.
