I know that meth is the best cooling mod but I am not really comfortable doing that since I know nothing about it...and I am hesitant to inject anything into my fuel.

Later this summer I am getting a heat exchanger...but I have some questions about the next cooling mods I will do.

1.How do the colder plugs work? Do they really make a difference?

2.What dual pass setup should I use? zzp's or crate engine depot's?? Is zzp's reliable because I from what I understand they are refurbished from stock units...is that right?

 

Meth and H/E are the 2 best for the money period!

Dual pass is minimal at best!

 

Meth is one of the easiest cooling mods, imo, and perfectly safe, if properly tuned for. Nothing wrong with a dual pass that was made from a stocker, as long as the work was done well. ZZP does good work, I wouldn't be concerned about it.

 

Not really. An aftermarket Heat exchanger does minimal work. GO for a beat run and feel your H/E, it wont even be that hot.
The do a dual pas, the dual pass allows the coolant to stay in the manifold for half the time. Their for the coolant does not heat soak and it keeps transferring the heat instead of becoming hot.

If yo go for a beat run after you install a dual pass you will notice your stock H/E will become hot. The after market H/E compliments the stock H/E when you have dual pass installed.

Somewhere in the words of ss.net past someone said that a after market h/e alone made a big difference. It's a common misconception.

 

X2 Can upgrade to a higher gpm h/e pump as well

 

the one we have is good

 

it does not stay in 1/2 the time it stays the same, flow runs 1/2 the path but at a slower flow rate

 

Here's the thing - the laws of physics dictates that a dual pass end plate would do a better job of cooling. The problem arises when the coolent is going through a heat exchanger that is not big enough, nor is it in a good location to properly cool it. The benefits of a combination of an additional heat exchanger and a dual pass will far out-weigh what either of them can do by themselves.

 

I like this info thanks guy. Ill be getting a cobra heat exchanger soon and then dual pass and later on when i upgrade to stag2 meth if needed. how hard would it be go get the h/e on and what will i need to buy? any how to thread on here? i havent seen one any help will be apreciated thanks

^^
thanks alot man

 

If I take a water pump that pumps 225 gph put 1" hose a Y(like a dual pass endplate) on it changing it from 1- 1 " output to 2-1" and measure the gph out of the 2 combined its still 225 gpg just less coming out of each so you have done nothing.yes I know it stays in for half the time but is moving half the speed . for the laws of physics to dictate that you must have the same output as input .I just dont see why people have such a hard time seeing this.If you do an endplate and not upgrade your pump you are not helping with heat enough to see a diff. . but if you do a pump upgrade alone you will not see as much as with the dual pass but you will see it.

this is a great pump http://www.steeda.com/products/mezie...oler_pumps.php and will fit in our pump holders and the plug is the same as the ford lightning which is the same as ours

 

You are welcome.

I am going to disagree with you here. Stock, the collant goes in, passes in one core, out of that core into the next, out of that one into the next, out of that one into the next, out of that one and out of the end plate. In a dual pass, it goes into 2 at the same time, out of them, into 2 more and out of the end plate. The coolent is split in half, so the amount of heat it accumulates is much less. The fact is that the laminova cores it what restricts the flow of the coolant. Not saying a pump won't help, but it is not necessary to see a benefit to a dual pass.

 

I don't see what you don't understand that the coolant travels through 4 hot passages, top to bottom. By the time it gets to the 4th passage it's absorbed all of the heat that it can. By only allowing it to travel through 2, even at half the speed is that it absorbs all of the heat twice as efficiently. I wish I could make a diagram or something.

The h/e is really a compliment to the dual pass.

Really, as stated previously, they work better together than the sum of them apart

 

^ Thats kool I dont mind as long as we can talk about it and see each others view thats whats helping each other is about .
I understand all of that but what you can not be adding in is the flow rate when you split it it slows 1/2 so yes like i said it runs a shorter distance .BUT it does take longer to do so.so it gains the heat almost the same.Shorter distance lower flow <how do you get the gains?

I am not being an ass or anything so dont get pissed please. take a piece of paper draw it with the gmp numbers on each line and look at it and tell me where the gains are and I will change my mind totally.

I just think to have it set up correct and the best you need all 3

 

so do plugs make any difference?.

 

Truth be known, they don't even move more slowly. If you've seen the holes in the cores, you can see that they would slow down the flow MUCH more than splitting the hose does. Let's take house plumbing for an example. You have 1 pipe that supplies cold water to your entire house. That line splits off at the water heater and creates 2 lines. Now you have 1 hot and 1 cold. Turn on the hot or the cold and you get a certain ammount of flow. Turn on warm (a combo of the two) and the water comes out much faster. It all started with 1 cold water line, so it shouldn't come out at a greater flow, but it does. That is because the restrictions in the plumbing system itself have been cut in half on each side. A lot like splitting the coolant between the cores.

...and no, I won't get pissed. I enjoy this. I do agree with the statement about the best being all three.

 

well I am not sure but I was told with my mods run a step colder by Matt at tunetimeperformance so I would think it does
.
lol yeah I know about the water in homes let someone turn on cold water somewhere else in the house while you are already taken a hot shower and your going to see the water temp go up .(just tried it)The static resistance is less with a dual pass which is why you do get some gains THERE are just more to be had with a upgraded pump ,lots

I dont have the dual pass as of yet I am getting it but from what Matt told me about the bennifet (sp)I went with the H/E , EXTRA RES,AND PUMP first .

 

Yes, cooler plugs means they have a heat range. Less chance of preignition. Usually people go with cooler plugs to compliment a smaller pulley, since the air from a smaller pulley is heated more than from a larger pulley.

 

so witch plugs should i run?.

bump

 

NGK BRK7E

 

I run NGK BKR7E . Depends on the type plugs you like I guess. ^ you beat me to it lol Love the color of your car .when I painted mine I went as close as I could in a hot hues color

 

Just so you know. With HP tuners you can turn your pump to 100% all the time such as mine is, You can also make it run when the car is in "ON" and not running to make in intake manifold cold to the touch in about 5 minutes. Try touching your intake manifold after 5 minutes.

I think that pump tuning along with the dual pass was the most effective of my cooling mods.

 

sweet. the guy that will be doing my H/E has hp tuners and i payed him already to get the credits for my car so thats a plus

 

Where is it that you make the changes for the pump to run 100% and in the ON position in HPTuners?
