We’ve got some exciting projects in development at 22RPD.

Currently working on:

• S54 intake manifolds
• S52 intake manifolds
• 8HP70 bellhousings for M5x, N5x, and S5x engines (No adapter plate needed)

Designed and CNC machined right here in the USA.

More updates coming soon.

Turbo E36 M3 on the dyno.

Engine built by 22RPD.
Custom A/C setup by 22RPD.

Currently set up for 500hp since the owner didn’t want much power, but there’s plenty of headroom for more.

This setup will easily do 700+whp on ethanol, and with a bigger turbo, 1000whp.

Peak numbers don’t tell the whole story.

A stock turbo N54 and a boosted N52 can both make 500hp peak, but the N52 can still be the faster car because it holds more power for more RPM. The N54 hits hard down low, but up top it starts running out of breath. A supercharged or turbo N52 keeps carrying power through the higher RPM range, and after each shift it lands right back where it’s still making power.

That’s why the N52 can be faster than people expect. It’s not just about the biggest number on the dyno- it’s about area under the curve in the part of the powerband you actually race in.

Same peak power doesn’t mean same acceleration. Once you’re WOT and shifting at redline, the car making more power across more of the RPM range wins.

The best of the best is here.

Our V2 production N52 velocity stacks are officially moving. The mold has been finished at the manufacturer, the first batch has arrived, and everything passed QC.

The manufacturer is now producing more units to fulfill pre-orders. Now that the mold is done, verified, and producing good parts, things should start moving much faster from here.

We appreciate everyone’s patience. These were built to be worth the wait.

“Too weak to boost” aged pretty badly. 575whp turbo N52. On pump gas. Tag an N52 hater.

05/05/2026

N52 turbo results are in.

575whp / 440wtq on pump gas, first session.

This is just the baseline. We’ll keep refining, but the foundation is exactly where we wanted it.

Manifold + turbo are doing serious work.
These will be hitting the website once we finalize the package.

Next step: stacking our custom code (speed density + flex fuel) and heading back to the rollers for more.

Blame for the delay…
Thank him for the edit.

Stay tuned.

You asked for a filter option, so we made it happen.

22RPD velocity stacks for N51 and N52 are now offered with an optional ITG filter. Same proven setup, now with a filtration option that keeps things clean without taking away from performance.

N52 swapped 335i with an in-development 6262 turbo setup.

This is a custom setup built from the ground up, featuring an in-house designed manifold that will be offered with our production N52 turbo kits.

More to come. Stay tuned.
