And... recommended? Not worth the money? Thanks.

These coolant manifolds are just replacements for the OE manifold. If your blower has been ported by Kong and you are still running the OEM manifold you are not taking full advantage of the increased coolant flow that their ported passages offer. This manifold directly replaces the OEM one and is opened up to match the flow that the ported passages offer. Nothing more, nothing less. You could still run one in stock configuration, but you'll likely get nothing additional from them outside of anodized CNC bling factor, which will lose its dark black coloring in time anyway and turn to a dingy black with brownish coloring to it because that's the way anodized coloring fades over time.

I have one on the way with the dual 3/4" -12an fittings to replace the smaller 5/8" OEM fittings. I had the RM individual port setup with multiple hoses feeding each port and it was a great setup but the fittings are poorly designed, the -10AN fittings are too close together and due to the design, there is not enough clamping load when pushing hard on the track to keep the driver's side from leaking.

I plan to install it even though my SC is stock and not yet ported... I just picked up another LT4 SC and plan to get it ported with sensors to measure actual data not the basic PIDs from the ECU.

If you really want to remove all the air from your system... and increase flow, our system is unmatched!

Thanks, my SC was X-ported by Kong so I suppose it will work better with, isn't it?

Only if it was ported recently. He started porting those water ports this year. Mines has the port I haven’t noticed a big difference, but to be honest I don’t have a before temp to compare. I’m sure It’s not hurting me though. But like one of our Camaro brothers stated without the port it’s just bling.

Correct, so long it was recently ported by kong, as this service was only recently added...

Before he did, and when my blower was off the car 2 years ago, I had hand ported those passage ways also, just not to the extent KONG did. Even with that porting in place, once I removed the restrictive OEM crossover tune, and added what is now our GMS Crossover Delete Package, I was surprised to see a 20% increase in GPM flow. Likely even more now that we have the manifolds ported to match the 20% larger water jacket circumference curtesy of KONG.

That said, and without testing the KONG crossover tube, I would assume at least a 10% increase in GPM flow... assuming less, as it is still not a dedicated in/out system.

I agree, it looks great, should flow more especially when paired with his new port work.

Also know, that KONG will upgrade from his older X-port to the newer X-port for around $1,200 +/-

In short, there seems to be (2) options for addressing the OEM crossover tube restriction to date. Both work, both look great, so it's really about which you prefer... I think the KONG unit is going to sell well, and is a great addition to the aftermarket options.

WOW!!! I haven't seen anyone post that porting before! It, definitely, seems like those should help with flow moreso.

I'm not sure how much that stuff really helps, but I'm of the believe making those little changes couldn't hurt. While the stock Magnuson plumbing works, I tried to do something similar in trying to smooth the flow as much as practical. I replaced the "T"s they had with "Y"s (which weren't cheap, lol), and tried to reroute some of the lines. I'm not quite done, because it's, still, not symetrical - I don't think it can be unless I change a lot more, which I'm not planning on it. But - what Kong's done looks 100X better! The manifold's probably, equally, improved!

Indeed, I agree those are the first photos shared...
Please note, the BEFORE photos are not from my car (I already ported mine 2 years ago) this is from the blower that I cut in half for top secret reasons HAHA

Forgot I had these also... for those interested...

The x-port was done in february…

Porting the water passages is cool to have a better fitting crossover, but unless the flow restriction of the actual bricks is eliminated, the returns of having the blower cooling passages is simply for aesthetics. I think people are obsessed with Flow and moving more water, but not focussing the attention to what actually pulls the BTUs from the Supercharger's Bricks. Moving the water too fast in the circuit will not reduce the MATs, as there is a balance of flow and keeping the coolant in the SCHX long enough to drop the coolant significantly enough to pull higher BTUs for each of the water molecules.

Factors Affecting Heat Transfer Rate over Time:

• Temperature Difference: A larger temperature difference between the water and the aluminum will result in a faster rate of heat transfer. This is why I designed my SCHX to get 100% of the water/coolant to touch the entire surface area before going to the DS Aux and then to the SC.
  
• Surface Area of Contact: The greater the surface area where the water and aluminum interact, the more efficient the heat exchange... nothing better than a triple-pass that holds 1.6 GALLONs of water!
  
• Flow Rate of Water: Increased flow rate of water over the aluminum can enhance convection and improve the heat transfer rate. Flow rate with added convection time is a double win. However, passing fluid rate too fast, slows convection!
  
• Thickness and Shape of Aluminum: Thicker aluminum might take longer to heat up or cool down, impacting the overall transfer rate. My SCHX end tanks are large, thin hydro-formed to improve convection while keeping flow rates high.
  
• Phase Changes: If the water changes phase (e.g., boils and turns into steam), a large amount of energy (latent heat of vaporization) is absorbed, which would significantly affect the overall heat transfer over time. Any Phase change is absorbed in the Expansion Tank and regulated at 5-psi so there is no loss or introduction of more air to the system itself. Self-Bleeding!

To calculate BTUs transferred over time, you would need to consider:

• The mass of the aluminum.
• The mass of the water.
• The specific heat capacities of both materials.
• The initial temperatures of the aluminum and water.
• The final temperature after a certain time interval.
• Any heat losses to the surroundings.

The dominant mode of heat transfer (conduction, convection, radiation).
Wrapping this up, water has a much higher capacity to absorb heat compared to aluminum. However, aluminum transfers heat more readily due to its higher thermal conductivity. The actual amount of BTUs transferred over time will depend on the SCHX design, ability to remove air bubbles and the heat transfer time involved within a closed loop.

Hope this helps!!

Yeah. THPSI went into that a bit when Magnuson released the 2650. Saturation in the huge intercoolers and such, and how they didn't want the water to move too fast but enough such that the heat transferred. He was their President at the time, I belive.

All interesting. All I know is my MATs fall 10 degrees on a 4th Gear pull every time, even 100* heat.
