My thought is as big of a tank as you can fit behind the dyno, then run flex pipe or softwall rubber exhaust hose through the upper portion of the tank above the water line, then install a large "squirrelcage" fan/blower in the top of the tank and vent outside. This should take all the fumes out and keep the water in. Then simply run a valve/ fitting at the top of the tank that will run up and feed the sea pump. I would be concerned with the water heating up quickly that's why I would say build the tank as large as possible. I would also run a large line with as much pressure and volume from your water supply to the building into the tank and run a drain off the tank to the outside right above the stagnant water line. This will allow fresh water to run in the tank while you are running with the hot water hopefully running out of the drain. Obviously you probably won't move enough through it to keep it cool for hours but I would think it would be enough to cool it for a few good pulls? I'll draw something up to illustrate what I'm trying to explain lol.

Smitty, I have heard that Tyler Crockett runs wet exhaust on his dyno. Maybe you can run over and check his setup out.

I'd run the exhaust water across and under the st into a shallow pool and watch all the fine ladies in the winter get into Smitty's Hot Springs.
Just a thought. (.) (.) I mean

Not to sound ignorant but how would you get at AFR or EGT wet?

Prior to the point where the water mixes in with the exhaust gas stream.

So that makes sense with dry exhaust, I still don't know how you read in a full wet scenario.
