MP90 G4 porting

SKU: MP90 G4 porting Category: Tag:


JB Performance case porting for MP90 G4. 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.

Please note that there is an extra fee for disassembly and assembly when not combined with a rebuild. We cannot guarantee the condition of any consumable components with supercharger porting services. Remember, this is port work, not a rebuild. If you wish to have it rebuilt, please choose this service when the item is sent in, so that it can be handled by the correct department. See rebuild section on rebuild pricing and information.
