Red Alpha Performance RA405 HPFP kit for the 3.0L VR30 twin-turbo. 47% more fuel flow over stock with 250 bar operating pressure — the big-bore option.
The Red Alpha RA405 is the high-output HPFP option for the 3.0L twin-turbo VR30 platform, delivering a substantial 47% increase in fuel flow over the factory pump at a maximum operating pressure of 250 bar. Where the RA338 serves as the entry-level upgrade with its 22.3% flow increase, the RA405 is designed for owners pushing significantly beyond stock power levels with upgraded turbos, built engines, and aggressive ethanol tunes.
Engineered with a larger piston diameter, premium welded construction, and CAD-designed / CFD-optimized internals. Each pump is individually bench-tested for flow rate and pressure control before shipping. The kit includes all accessories for installation. Tunable on EcuTek. This product is sold exclusively through AMS Performance — please visit amsperformance.com to purchase.
