2011-2013 Mustang GT Cooling Head Mod by MMR, eliminate the #8 cylinder failure today

No Problem!!

Now does this really a make a difference on a stock engine?
Or is this more for forced induction setups where you get tons of heat?

Looks like a fun and beneficial project I can do on one of my days off. But like a couple members have stated, is there any data logs showing the cooler temps by this mod and possibly a write-up of the installation? Maybe one of the members who have already done this can shed some light.

My boss is lightly modded and probably doesn't need this at the moment. But I support MMR and their quality products

This mod is certainly beneficial even on stock engines, the parts benefit is not so much the temperature but the ability for the ecu to make calculations based on the coolant coming from both heads instead of one (because we have joined the banks right at the point where the ECU takes its readings). So no only do you have better coolant flow around the #8 cylinder but you also have the ECU basing its calculations on the actual coolant temps coming from the cylinder in question. (and to be clear the ECU uses a head temperature sensor- not a coolant temp sensor but they work in a similar manner.

MMR,

I have a question So I am reading this right, it can be installed while the engine is in the car? Do you have any pictures or links so I can see this? Iam swapping my transmission soon and would like to do this as well I just want to know how to do the install with the motor still in the car. Thanks

 

[Modular Racing]

Correct, it is more difficult but can be done. If you are changing the transmission it is a breeze if done at that time.

How much pressure can that back hose take before it pops off without clamps?

 

[Modular Racing]

The hose is a pushlock design, designed for 350 degrees and 120psi , to put things in perspective the cooling system makes 16-20 psi max and runs in the 220-230 degree range. The hose used is the same type used for fuel injection systems and is a clamp less system.

Ok well I'm putting in a Boss intake so... Who here has some directions how to do this while the engine is still in the car?
I figured I'll do it and get it out of the way while the intake is going on!!

I'm interested in this but would like to see some data can you pm it?

 

[el jefe 302]

^ Good luck

I asked for data in DEC 2012.... still waiting...

Look at page 1.

 

[Modular Racing]

What type of Data are you looking for and perhaps we can post our findings. For the most part it is a very simple item that balances flow between cylinder heads and also allows the ECU to take a more accurate sample of head temperature - this in turn makes sure that the calculations are based on the higher temps that we tend to see coming from the driver cylinder head which does not have a temp sensor in it.

On here it says 189.99 on the link it say 199.99

 

[Modular Racing]

fixed , the price on this thread was the old sale price - current price is $199.99 for the kit

 

[grabberblu5.0]

Ok thank you I just wasn't sure which price is was
