Subaru VF43 Single Scroll Turbo Process West Manufacured from pulverized lava rock

Manufacured from pulverized lava rock and stranded into a fiber material which is then woven into a proprietary weave

they are then heat treated

Our added Performance Fuel Pressure Regulator will allow maximum fuel control with absolute minimum flow restriction for engines up to and exceeding 1500 HP

In a fully machined piston you don’t get any true grain flow structure as you are using the material as it is cut from the bar

the case is loaded and fixtured back into the VF-4SS after reaching room temperature
