LS2 Intake Manifold Porting - LS2 Stealth Mods
|
Since the internal sealing of the manifold can't be addressed in the aftermarket, Vmax Motorsports came up with an LS2 manifold porting program to flow more air through the manifold. The runners are shaped using 1/2-inch and 3/8-inch carbide cutters, which are then polished with 60 and 240 grit roll sandpaper. Porting is accomplished using a Dumore straight handle grinder.
