JB Performance case porting for 99-03 Ford Lightning M112 Supercharger porting. The entrance is eyebrow ported extensively to allow more air to enter the supercharger. Port timing is not altered. A double arrowhead design on the bottom allows a large amount of air to discharge, allowing for cooler discharge temperatures as well as increasing the efficiency of the supercharger.
Port timing is not altered. We do not epoxy silencer holes. Epoxy just works loose overtime causing significant damage to the supercharger. Dyno results have not shown any HP increase by altering the silencer holes.
Supercharger must be fully disassembled or extra labor fees will apply. No warranty is provided on supercharger porting as no components are being serviced. If you wish to have a warranty, please choose a rebuild service with your port job.
