Would reversing the lines going to throttle body have an adverse affect on thermowax? The typical route goes fom rear iron to thermowax then back from top of TB and to the nipple on front cover. Would flow from rear iron to top of throttle body then from thermowax back to front cover disrupt anything? Here's a pic of the stock flow

No issue. There are no one way valves or checks in the throttle body.

i'm not sure why you'd bother, but i think it would work ok. off the top i think the coolant just goes around the wax pellet, so it doesn't care which way. unlike a thermostat, where the wax pellet is on one side, so if you flipped the hot and cold coolant, the wax pellet would never see the hot

Not exactly, but the end result is the same, so I'm just being that pedantic *******.

The coolant enters a chamber in the thermowax body and exits via the other end of the chamber.
The themowax pellet is only exposed to the fluid on one end...the other end is what you see when it expands. It's in contact but not immersed in the coolant. So it doesn't matter which fitting you bring water in and out, one way or the other, it hits the wax pellet.

All blather aside, that's how it would work on a NA, you apparently have a turbo and I'm not sure.

Thanks for the clarification guys.

that is an S4 T2. it makes that hose to the iron really short, and while its easy when the engine is out, its not easy when the engine is installed.

they fixed that for the S5's, and the nipple points backwards, so the hose is like a 3D question mark, and its easier to deal with.

the S5 pellet goes right on the turbo throttle body, not sure why that isn't a more popular thing

Yes. This is s5 motor with S4 intake. Since I'm using non factory hoses I need to find routes with least bends etc.
