On the Dyno
We had hoped to test JLT's new 12-inch Next Generation High-Boost Cold-Air-Intake Kit on an '03-'04 Cobra making substantial horsepower with a bigger supercharger. Unfortunately, said vehicle wasn't available in our time of need, so we elected to bolt the big tube onto a relatively stock Cobra and see what type of effect it has on horsepower and torque. With the air filter relocated in the front fender and the element itself being so big, we were confident the system would help produce impressive power gains, despite its high-boost requirement.
Study the dyno results closely, the impressive gains on a mostly stock '03 Cobra are good indicators as to how well this system will perform on the stronger Snake. "JLT1" represents the JLT Short-Ram CAI that was tested after the factory airbox and inlet tube. Data for the new high-boost intake is listed as "JLT2." We also made one unofficial glory dyno pull ("GLORY") at the close of our test. While all of the data for this all-out hit is accurate, it's important to understand that it was made with the Cobra--and moreso its supercharger--set up for achieving maximum power with the new setup (engine cooled for one hour, supercharger iced down).
The comparison information for this project does not include the numbers achieved during the glory run. While the glory run's 428 rwhp is outstanding for an otherwise-stock Snake, the real data point of interest is the overall boost increase that the high-boost setup promotes, which is measured between the OEM and two JLT systems (without the cooling tricks).
With most "new" performance hardware for '03-'04 Cobras being power-adder systems, the JLT 12-inch Next Generation High-Boost Cold-Air-Intake Kit is a cool and affordable new addition to the upgrade selection for Terminators. We saw it first-hand--this cold-air kit and a Blow-By Racing tune is all that was necessary for a 50hp gain!
