Sheet metal intake manifolds are super cool when finished and a huge pain in the butt if you aren’t good at them and don’t have the ability to make the various components quickly and cleanly. There is a reason these things cost real money, and always have. Hell, it is easier to build one in 2025 than it was in 1995, that’s for sure. But if you have all the parts already sized and cut and finished and ready to weld together, it can be a fairly straight forward process. But how straight forward? Watch this Bain Racing timelapse and see just how one of these intakes goes together with an expert welder and fabricator on the job.
Video Description:
You can’t buy what we build. Watch us hand-fabricate one of our custom shotgun intake manifolds from raw materials to finished piece in this satisfying time lapse. This beast is going on a 1200HP ProCharger small block Chevy running 18 degree heads – and off-the-shelf just doesn’t cut it at this level. Why go custom?
Equal runner lengths for perfect cylinder balance CSA calculated for optimal air speed and inertia Smooth transitions that don’t kill boost pressure.
Plenum volume matched to the engine’s demands Every cut, every weld, every bend – designed around the math, not guesswork. This is what it takes to feed 1200HP properly.
