VK56 Intake Manifold — Sheet Metal Lower, Printed Bellmouth Runners
Built to order for the Nissan VK56. The same hybrid construction as the LTx and Coyote manifolds, now for a platform almost nobody builds for: a hand-welded sheet metal lower body for plenum volume and shape, 3D printed aluminum runners with a full bellmouth entry that no welded tube can reproduce, and billet 6061 head flanges that will not warp, move, or leak.
How It's Built
-
Sheet metal lower body — hand-formed, fully TIG welded
-
3D printed aluminum runners — full radiused bellmouth off the plenum floor, sweeping into a tight-radius elbow so the charge turns without stalling
-
Billet 6061 head flanges — machined solid, VK56 bolt pattern
- Printed aluminum throttle body flange
-
Printed aluminum vacuum plate — reference and boost ports integrated
-
Port injection ready — 14mm injector bosses at the runner base, right above the flange
-
125mm tapered velocity stacks — the geometry this whole family is built on
Proven Design Language
This is the same plenum and runner philosophy that was tested at Power Fab Autosports on a supercharged Corvette — Mainline DynoLog, SAE J1995 corrected, same car, back to back: 625.9 HP stock · 636.4 HP MSD Airforce · 643.0 HP G1Pro. +17.1 over stock, +6.6 over the MSD, and still climbing where the others had quit.
On the Coyote side, Cantu Racing put a G1Pro intake with an off-the-shelf stock throttle body against a ported Cobra Jet manifold with a ported CJ throttle body — and it won.
The pattern holds: trade a few pound-feet down low for power all the way to the top. Built to pull to 8,000 rpm, only starting to wake up where a stock combination is already finished. The VK56 responds to exactly that kind of top-end breathing.
