Ford 5.0 HO Stage 3 ported manifold vs Stock Ford Explorer gt40 manifold.

Here's a video that we made of a customers stage 3 ported HO manifold vs a stock Explorer gt40 manifold per his request. Our stage 3 HO manifolds flow around 238-242cfm bolted together and has the runners shortened and fully ported to extend the rpm capability of the manifold. It also gets its throttle body tunnel ported to 70mm and the flow is increased as well. This is a comparison test to show you how well our porting can improve on a manifold that many throw away. This manifold now outflows and will out perform many of the entry and mid level aftermarket manifolds like the TFS street, Edelbrock performer, PP Typhoon, Stock Explorer gt40 even with the lower only ported. More air flow equals more hp. Like and Subscribe to our YouTube channel and Facebook page at Bigdogs Porting for more information and contact. #portedhomanifold #mustanghomanifold #mustangmods
