This unit was Tested and made @ AFCO for JLP We will have The Data here shortly. be not mistaken the Quality is Top Notch! And its effeciant rate exceeds far much more than the stock unit could ever do. We Believe this unit will remove the heat from the intercooler coolant as well as any other aftermarket unit or better. The size of this unit was decided after Much testing.. The size of this unit is perfect! The larger unit that was tested did not lower the temps any more than this size and it wasn't a nice direct bolt in because of the bulky size..I'm sure you will be 100% sastified.. We sold 10 units so far so we'll be getting some feed back shortly... JL

Cool, Johnny. Thanks for the additional information. I look forward to some testing data.

I hope so!!!! I cant wait!!!!!!!!


But I wish I had a GN,03 cobra and a lightning in my garage!!!!!
I wouldnt know what to drive!!!! LOL!!!

HaHa. The GN has a blown motor now so that is the out of the question. I drive whatever I am in the mood for really unless my leg hurts(like always) then it is the Bronco or Lightning. Goodluck with your truck! I hope your rip off some good times. -Mat-

I want to do this mod, but I'd like to know what kind of testing went into the design. The effectiveness of the heat excahnger is composed of the cooling surface area provided by the heat exhanger, the flow rate of the intercooler fluid, and air flow across the heat exchanger and the heat conductivity of the metal, among others. They are all interrelated variables and the optimum solution isn't necessarily bigger...

Can we get a little more data on the design of both units and some expected performance numbers from the units?

Thanks
Right, but of the variables listed above, the only one which is not constant for our application is the surface area (the metals must be very close in composition). Other things being equal, bigger is better, subject to the law of decreasing marginal returns (which just means how much better). The only real equalizer could be if the JLP design presented more effective surface area per square inch of frontal area.

Intercooler effectiveness can only be measured under steady-state equilibrium. Outside the lab, this would mean sustained high-speed driving until the fluid temperature stablizes.

I would suspect that the larger JDM cooler would work better in short runs, no matter what, simply because it presumably both holds more fluid and has more metal for the heat sinking effect. This would presumably allow the JDM exchanger to better absorb heat shocks from short-term blasts. Add a 5-gallon reservoir, for instance, and the system's ability to absorb transient heat shocks is improved, while its steady-state performance is unchanged.

But if the JLP cooler is more a more effective design, the steady-state fluid temperature could be lower than the larger JDM.

No matter what, hats off to JLP for bringing another option to the market. Looks like a very nice piece.

Instead you have to choose between a Novi 318 Cobra, a Lightning with a built motor and nitrous, or the Escalade.

Waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahhhhhhhhh

You should've gotten the 95 Wrangler instead of the Lightning!

HEHEHEEHE my moms ride is slow...... but it does make it fun being able to smoke my friends 6 cylinder camaro......
I don't really see that cobra very much cause I dont live at home ... Hopefully when summer hits and pops lets me bring it out, I will
and when the lightning gets back I will let u guys know how much fun it is!!!!!

Doesn't sound like you are all that bad off. HaHa. -Mat-

Changing the size of the internal tubing of the exhanger could create dead spots in the tubes the they are too large for the pump to keep full around the entire tube inside and would harm efficiency. Smaller than oem tubes in the core would increase velocity and could cause changes in cooling efficiency -- could be good or bad. I assume the metals are equal in composition but there are coatings to improve thermal transfer. Nothing was noted it appears to be raw aluminum, so I doubt there is anything on it.

Certainly I buy the larger tank theory, but does the larger core have larger tubing?
