M90 Supercharged E90
1-of-1 custom Eaton M90 build. Assembled and dyno-tuned end-to-end in our own shop.
Velocity stacks, supercharger kits, Cosmetic upgrades, and the 22RPD upgrades that put the N52 platform into the 500HP+ territory. Engineered, tested, and validated on our own builds — not catalog-flipped.
Velocity stacks, diff covers, charge pipes, cooling & chassis.
Carbon paddles, spoilers, LED markers, push-start & more.
Hoodies, tees, flags, mugs & beanies. Wear the build.
Inspected, tested, photographed. Pulled from real builds.
MSV70 / MSV80 DME remaps. Smooth power to 7,500 RPM.
ESS-based supercharger kits making 300–500whp+, plus wet 35–150 nitrous shots.
A throttle-body-delete intake that runs straight off the N52's Valvetronic. Runners optimized for flow and a wide powerband — so they wake up the top end without killing low-rpm drive.
1-of-1 custom Eaton M90 build. Assembled and dyno-tuned end-to-end in our own shop.
22RPD throttle-body-delete stacks beat the N54 intake manifold peak and erased the mid-range dip.
Linear powerband from idle to redline — no turbo lag, no surprises. Equally at home on the street and at time attack.
Real speedo + tach pulls — no overlays, no editing. Filmed in the gauge cluster.

N51 is the SULEV variant with lower compression, extra emissions components, and tune. Most of our parts fit both.
Our ESS-based N52/N51 kits come in Base, Stage 2, and Stage 3 — each with tuning, 60# injectors, and matched spark plugs. With supporting mods they make anywhere from 300 to 500whp+, depending on pulley, fuel, and methanol. We charge a $125 consultation deposit to spec the right kit for your goals; it comes off the final price.
