MMR cooling head head mod

[WildHorse]

Does this mod even do anything? I dont see it.

Does nothing but drain the wallet.

I take it you think its bs that the number 8 cylinder in the coyote and 5.2 get much hotter then the others. I guess the detonation issue’s on that cylinder don’t exist as well. Plenty think a bigger radiator is a waste of money to. Makes no difference to me if someone installs the bypass or not. You guys can look it up yourselves, or not.

What data is available that supports "stop the hot spots"?

Well prove it instead of preaching it. I never seen anything unusual in my logs. #8 plug looks the exact same as all the others as well.

id like to see proof its a benefit. i thought honeybadger was going to have a sensor installed in line but i believe he pulled it out but left the oil crossover tubing in place.

Not to change the subject but WildHorse, I miss your mustang-emerging-from-a-cloud-of-tire-smoke avatar.

Carry on.

Oh.. Well hoping to hook up with a hot chick.. Ain't panning out. I'll put up something else. Haha.

I take it you take things as they are presented to you. How does crossing over at the back of each head solve this issue? Makes no difference to me if you cannot provide this data, i just figured id ask.

I'd have to see a 3D of the cooling system and how it flows. I admittedly bought and installed (the motor was out and it was cheap add) based upon speculative information (no real hard data) but on the flip side, it's more than just MMR touting that it helps reduce the problematic #8 hot spot.

I'll concede we haven't seen any real data to back it up, but I suspect it helps to provide lower temp coolant to the 8 hole where it's probably the last of the hogs eating at the trough and the coolant is warm(est) there without some sort of crossover to help balance it out.

How does crossing over at the rear of the cylinder heads solve for the issues mentioned? Where can one find the data showing a reduction in temperature at the back of the heads after this kit is installed?

To my way of thinking to get more flow at the rear you would run the hoses from the back of the head directly to the radiator inlet.

Now we're talking.

Did you actually read my post? I'm conceding I've never seen any data. If it exists (doubtful) we're both in the dark about it.

Your point is taken, there's nothing concrete to support the claims.

And yet, the same also cuts the other way. Do you have any data to refute that it doesn't help temps in #8?

And 3D I meant of the channels in the heads and block.

If coolant returns from the radiator and enters the motor/heads, by the time it reaches the furthest point before being sent to the exchanger, it will be the hottest point. Temperature gradients are quite common in mechanical and chemical processing systems where cooler material enters heat constant heat transfer and by the end of the line, the coolant's capacity is diminished.

A crossover would be a sort of recycle to balance out the coolant temps at the beginning of their run vs the end and result in less disparity between points of the linear system.

This is admittedly all speculation until we see some real testing.

I find your skepticism healthy but also a bit zealous.

You are correct, there's nothing to say this works. Now prove to us all it doesn't work.

That wouldn't create more flow, it would just rearrange the current flow.

I suspect it's simply to send slightly cooler coolant to the back of the line and end up with less gradient between the start of it's heat sink and the end.

I can post some pretty interesting stuff on reverse vs standard flow in thermal exchange.
