I would have to say only around 10# WITH a bag of ice in the cooler, but being able to add timing due to ice water running through the system, I am fine with it.Originally Posted by Steel Armadillo
Yes it a giant reservoir. It is all about surface area. If you have a second heat exchanger in the cooler, there is less surface area for the ice to hit, with this setup, as soon as the water goes in, it hit the ice chunks and cools. That is why I put the output to the pump at the bottom of the cooler, to make sure it is pulling the coldest possible water out.
They NEVER get hot. After a 1/4 mile run, the water is still COLD, it blows me away as to how well this works. If it is a cool night, there will still be small bits of ice left in the cooler and all the lines running to the IC, are cold to the touch, and the front mount is COLD. And when I pull the cooler out to do tuning on the street, and turn all the valves, there is no fluid running through them. Plus these valves can handle up to 140 degree water temps, so I think I will be fine with them, but good to know though.
This is how it is all routed:
Water is pulled from the cooler
To the pump
Into the IC
Out of the IC to the top of the FMHE
Out of the bottom of the FMHE, back into the cooler
When the valves are turned off for when the seat is put in it is run like this:
Out of the IC
Into the TOP of the FMHE
Out of the Bottom of the FMHE to the pump
Pump to the IC
I hope that makes sence to you, like I said before, when I first installed it, it took me a minute to figure out my own work.
Yes, yes it is. A friend of mine runs a machine shop and makes them for the local law enforcement cruisers and he had a extra one laying around. So I put a bunch of holes in it on the mill to make it lighter and modded it to fit. Works great.
