SFPH is proud to announce a C&L Performance truly unique and innovative product for owners of 1999-2004 Lightning and 2002-2004 supercharged Harley trucks. This new upper intake manifold replaces the stock unit that delivers air from the throttle body to the inlet of the supercharger. During the development of this item, we found many improvements could be made over the original design. The most obvious of which is the fact that the opening at the blower end is actually smaller than the supercharger inlet. Roots style superchargers are extremely sensitive to restrictions on their inlet, and their actual efficiency can be improved by simply reducing airflow
restrictions at the inlet side of the charger.
After flow testing this new design, we are happy to report that it has exceeded our expectations. We have supplied a flow diagram below so that you can understand how this new manifold can benefit your particular application. Most people who have already upgraded their factory throttle body to a single blade design have reported gains in performance ranging from between 7 to as much as 10 additional horsepower. Flow testing has shown that this arrangement increases airflow through the stock upper manifold by 10.9%. People who already have the single blade throttle body and upgrade to our new intake will see a nearly 20% greater improvement in flow, for a total flow improvement of 29.8 % over the stock throttle body and intake combo. For those people who do not have an upgrade throttle body and would like to upgrade the intake manifold, you will be rewarded with a 14% increase in flow over stock, which is greater than the improvement that people have seen in the past when installing a single blade throttle body. Intake Configuration Flow Rate % Increase Over Stock Stock Plenum/Stock TB = 850 CFM (Baseline) Stock Plenum/Single Blade TB = 943 CFM (10.9% Increase) C&L Plenum/Stock TB = 970 CFM (14% Increase over stock!) C&L Plenum/Single Blade TB = 1103 CFM (29.8% Increase over stock!) Dyno testing of this new manifold has already been performed. Both tests were done using mildly modified Lightning's, and the results were similar. When using a single blade throttle body, the test vehicle saw a peak HP gain of 21 and a torque increase of 30 ft/lbs. The same test on our local '99 Lightning test vehicle posted a 20 HP gain and 25 ft/lbs of torque, although we were unable to see the maximum torque gain in our testing, as it took place in 3rd gear where the RPM's are above peak torque levels. When testing the upper manifold alone with the stock throttle body still attached, the results were an increase of 14 HP and 24 ft/lbs of torque over stock. Testing this intake by itself on a 600 RWHP Lightning with an upgraded supercharger and a single blade throttle body previously installed showed an increase of 18 more rear wheel horsepower. The gain over the stock intake and throttle body was at least 25 RWHP. In case you were wondering, installation is very straightforward and can be performed by anyone who is capable of changing the throttle body. The first production units are being shipped now and you can order directly through us or any of our distributors.
