PFS S55 F8X Drop in Brushless LPFP upgrade (1000hp)
PFS Brushless LPFP for S55 — 1000+ WHP Capable
Looking for a true drop-in, plug-and-play LPFP that can actually handle power? The PFS S55 Brushless LPFP is your solution. No extra pumps, wiring kits, or funky controllers — just OEM simplicity with serious performance.
Supports:
- 850+ WHP on E85
- 1000+ WHP on race gas or blends
What Makes It Different
We start with a factory S55 bucket and professionally modify it to accept our high-flow brushless pump. We re-terminate the factory wiring with OEM-style precision — no splices, no shortcuts, just like BMW would do it.
Every pump is:
- Fully flow-tested in-house
- Pre-wired and pre-assembled
- Ready to install with zero tuning required
Just remove your stock unit, drop this in, plug it in, and go. The ECU controls everything.
Why PFS?
- More flow than any other drop-in on the market
- No additional wiring or controllers
- Flow-tested, road-proven, track-ready
Need more fuel?
For extreme builds pushing beyond the limits of a single in-tank solution, we’re currently offering a limited number of S55 pumps with our side chick brushed. These add a couple hundred horsepower more of fuel. Coupling the highest flow drop in brushless on the market with Walbro/Ti brushed reliability is an economical and sane way to push the limits of an in-tank system without going surge tank/external.
