I was just pointing out that the water pump on the lower front of the engine is the inlet and not the outlet. The water goes into the block there and out at the back of the head.

No I get it...front to back. We're splitting off some of the incoming cool water for the turbo. Theoretically the coolest water will be available right after the radiator and before entering the block.

Our turbo exit line meets up with the rest of the hot water after it's exited the block in the back, so hot turbo water doesn't have to go through the block before first going through the radiator.

The fact that you posted this makes me terrified that you've actually made a driving tube frame car.

Yup, you'd be reversing the flow you think you're going, feeding the hottest water to your turbo. Think water pump, then think pressure differential.
Now if you have an external pump before the coolant enters the block, and feed coolant to churbo right after it, then cool.
Edit to add: my track car was plumbed the exact way you're describing, but I used my heater core in-line before the turbo acting as a radiator. Yes it got hot in the cab... but I never had fogging issues

Where is the thermostat?

Correct but theres no water pressure where you connected your inlet. You want that inlet to be on the other side of the water pump.

If I see correctly you have the best source for cool water right next to your oil feed (MSM/94/GTX block).


(Water feed is the one without the red circle )

Tap in there and you have the best routing for your turbo water lines. Feed from the block and return after the thermostat to the KIA cover/upper hose.

The thermostat is at the back of the block.

Here's my thinking: it's a closed system. The pump keeps the water flowing in a circular motion, even to the point where the water is seeing pressure at all points.

Vuti

If you have a closed pipe with two identical (low) pressure points at each end, does the water flow through the pipe?

Good point. I was just picturing "flow".

Vuti

Just change the pickup for the block port and your system is golden...

No, if you were seeing equal pressure at all points, the water would not be moving. The pressure before the pump will be lower than the pressure after the pump, otherwise the pump wouldn't be working.

I made this car in collaboration with some of the best builders in their field. I listened to what they had to say and then incorporated their knowledge into the design, which is what I'm trying to do here. Most posts here have been helpful...

Same here, with the heater core supply being before the thermostat of course.

Cordy is just having a brain fart, it happens to us all. 'tis friday, afterall.

Thanks Tim. Happy to have given you your 100th prop.

One thing that's been pounded into me with this build is that "failure" equals progress, if you know how to react to it. It's the application of the scientific method where you're supposed to test a theory, have it fail, learn from your mistakes, and then adjust the theory with the lessons you've learned. That to me is a huge part of the satisfaction of the build process.

But getting to watch some members of the peanut gallery uphold the reputation of MT.net, not so much.

Hey, what would we be without our reputation?

Looking forward to seeing this project completed, and seeing the car in person in September.

Not true.

You also disassembled the best looking car on the forum creating much sadness.
