Correct the 8x10 Barrel which is the largest stock model they offer. They also custom build anything. - Not sure what # means but its dims are 8"dia x 24" lg (thats o/s to o/s - which includes app 8" for the inlet and outlet) So the actual 8" diameter where the core is would be app 18" - would make it app 450ci I think
I use engine ice, it's got several different names depending on the company. I've seen it called Water wetter, Pro cool, and a couple other names. Engine Ice is about $40 a gallon. Don't know about the others.
How about dry ice. When it melts it doesnt leave water is what i have always understood. And its suppolsy colder then regular ice. Sorry for mis spelling guys spell check aint on this computer.
