JBP 4-Pass Intercooler

You just use 8 Laminovas in a parallel inlet 4 pass series arrangement. That would double the area of the intercooler. Think outside of the box !

The dual inlet runs fluid through all 4 cores at the same time, but straight through, (like a 4 lane highway as opposed to a 1 lane twisty road) so the fluid is circulated faster through the intercooler, meaning it doesn't heat up as much, and because of that is more efficient at cooling the air.
I'm no expert on this, but it sounds like that's what he's trying to say. Some e-whack me if I'm way off on this.

I will break down the properly posed questions and ignore the filler:
Whats the difference between the stock pump and jbp pump?
STOCK PUMP:
Stock Pump = Centrifugal, Butyl Elastomers affixing neoprene impeller radial design..
Stock pump flow, using metered coolant we measured to be 24.5L/min. Total Head, unknown, per m/h20.
JBP PUMP:
Centrifugal design, Bronze Impeller, Impervious to debris, damage. NPT connections and 39~47L/min flow. Pressure testing to be @ 0.15 - 0.3 bar implied. Total Head 2.87M/H20
Whats the difference between the stock intercooler and your intercooler?
STOCK SETUP:
Single Inlet/Outlet
Serial Run
Out to Aftercooler
Rubber Lines
JBP SETUP:
Dual Inlet/Single Outlet
Parallel Run
Out to Surge Tank (optional)
Out to Aftercooler
Bolts up to stock location
Braided #12AN Lines
FLOW PATTERN DIAGRAMS:
Stock flow description: I will assume that stock flow is understood by all and doesn't need further explaining.
JBP flow description: The top inlet handles the top two laminovas, The bottom inlet handles the bottom two laminovas. Output is channels into one fitting.
LAMINOVA CORES:
Stock Laminovas: I will assume that people who are "confused" have disassembled the stock laminovas, examined their material construction alleviating further description.
JBP Laminovas: GM Stock laminovas are fitted with a new layer of "material" (We CAN NOT mention) over the exposed air charge. There is also a 4 additional metered pressure orifices placed directly in the flow of coolant to maintain our desired coolant flow. Laminovas are also repositioned to achieve the pressure difference required by thermal dynamics to achieve better cooling.
Keep the proper questions coming, I'll be able to answer them tonight.

Civil post:
Why is a new pump necessary for this modification? The stock pump should not be working any harder than before. It would be moving the same amount of fluid, but the total pressure will be a tad lower due to running the cores in a different configuration. Additional pressure from the outlet notwithstanding.
I'm only guessing at the configuration, but i'm assuming they would be running in a half/serial half/parallel configuration. Two sets of cores in series running in parallel.
Also, I understand that you can't mention the material (trade secrets and all that), but you will still be limited by the heat transfer properties of the core materials, no matter how many layers of secret materials you put on.

This is why some heatsinks are made of aluminum, but the surface that touches the component to be cooled is plated in copper. It's all about using the surface area as best as you can.
At least thats how my mind is wrapping around it. Ugh...I have to go and look over my heat transfer notes now.

Geez, this is at least the 2nd time that they have "released" a part without anything to back it up. Next time, they need to wait and have proof of gains, people aren't willing to shell out money for a part, just because they claim it works.
(That would be a constructive comment... )

Besides, getting into a fight on a forum is ALWAYS a losing situation for a company, whether they win or lose the fight...
Like all products, we will know its true value once someone buys it and tests it...

Don't expect them to answer to the many morons who blindly attack (or ask stupid questions) just about every product that comes out and then whine that no one makes aftermarket parts for them anymore...

At this point our lee-time for pump restocking, as given by the manufacturer is, 4-5 weeks. At that point, intercooler kits will be manufactured upon order.

The people who want JBP's products will phone and get real time answers to their questions.
