Peter Pan Coolant Reroute
#101
Ok, here is my thought, what do you guys think.
Hypers design has one flaw. the mixer is broke. No circulation when the thermastat is closed. Therefore, no heater, no turbo cooling.
If he puts the thermastat in the back, it is nothing diferent than a normal reroute.
But so far I do like some of this design. But my next thoughts would hinder heat up times in the winter.
Iinstead of piping the heater out into the thermastat, bypass the thermastat and hook the return into the top radiator hose. The mixer isn't broke. water flows, but the motor will take longer to warm up. Since the thermistat is being bypassed partially. But for the race application, who cares about heater.
It comes back down too, do you want a race car or a daily driver.

Thats going to be alot of water trying to get thru the heater core and small hoses. Not to mention you are now FEEDING your turbo the hottest water. I think it gets even worse. After you feed your turbo the hottest water, the turbo will heat it up even more and then send it back into the motor. Probably a small amount but still.

Yeah. The big issues here are:
1- When the thermostat is closed, the only way water can circulate through the system is through the turbo. Since this is a small and restrictive path, flow through the front of the engine will be reduced and flow through the rear of the engine will still be virtually zero.
2- When the thermostat is open, total circulation through the engine will be less than with a rear-thermostat reroute, as the primary cooling path is more restrictive.
(and of course)
3- He hasn't actually implemented this, he's still running with no freeze plug and zero flow through the back of the block.

You know, this whole thing really reminds me of the airplane on the treadmill argument. No matter how long it goes on, you still have one group of people trying to explain basic physics to the other group of people, while the other group of people think the first group are retards who are overlooking some presumably obvious fact yet are unable to clearly describe what that fact is, until somebody finally mans up and appropriates a C-130.

Think about this again. This is exactly what I don't like about the BEGi "Re-route."
Moving the heater return to the radiator inlet causes the flow to lessen (pressure differentials) and warm-up to time dramatically increase (lack of recirculating water).
Turbo inlet and outlet stay the same....water flows from the waterneck to the mixing manifold, not the other way around, so the coolant is still always the hottest there.
What I'm trying to figure out is why we don't use the coldest coolant source on the block above the factory oil source, as seen here: http://boostedmiata.com/blown_engine...nebuild001.jpg

Brainack, Oh yea, on a cold morning you would be screwed with the no mix. But for racing on a hot day, and reroute this way, and use the colder coolant to the turbo you are talking about. You should be better for the track.
But I bet my car doesn't even get a re-route. Unless my girl goes to work full time and I decide to track race. Otherwise I'm good. I mainly tool around.
I need the heater, and definatly the A/C!!! If the car has no a/c I will put it on, or sell it!
No one likes a sweat dripping person coming into work.

There would be no more cooler coolant to the turbo than without the heater core bypass.
Water does not reverse flow through the turbo because you magically decide it should. It will flow from the front of the motor, into the waterneck, through the turbo, into the mixing manifold.
The only way to get truly cold coolant, is to source directly AFTER the water pump...You gotta think of the pressure differentials. If you tap into the mixing manifold (before the water pump) then your exit needs to have less pressure....there's nowhere this exists.
If you happen to tap after the water pump as your source (higher pressure, low temp), then you make the outlet before the water pump (low pressure), then you'll have you best turbo and oil cooler source.
