The B58 Gen 1 Gauntlet HPFP Kit represents Nostrum’s latest engineering in cast stainless steel pump technology.

Maximum operating pressure of 240 bar (3,500 psi) with a geometric displacement of 1.603 cc/rev.
Plug-and-play installation requires zero hardware modifications to stock components. The kit is fully reversible to factory configuration. Supports up to 1,022 WHP on gasoline and 730 WHP on E85 (fuel system capacity). A tune is required to start the vehicle after installation. Compatible with EcuTek, MHD, and Bootmod3 calibration platforms.
