The design validation testing surpassed all specifications and standards! Design and development of the pump included computational fluid dynamics (for internal flows), kinematic analysis (for high rpm spring specification), finite element analysis (for structural and spring support development) as well as 120+ hours of component dynamic testing on a HPFP test bench. \u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003eQ: Is this pump compatible with Dorch lift kits for n55?\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003eThe Gauntlet pump H086-1859\u003cstrong\u003e\u003cu\u003e\u003cspan\u003e \u003c\/span\u003eis\u003c\/u\u003e\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ecompatible with the +38% N55 lift kit, as tested and validated.\u003cbr\u003eHowever it\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e\u003cu\u003eis NOT\u003c\/u\u003e\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ecompatible with the +49% N55 lift kit, as observed in an M235.

All Nostrum products come with a detailed installation guide that shows you how to install your new parts every step of the way. Any additional pieces that might be necessary are included in the box. The only thing you need is your own tools and a can-do attitude. A tune is required for this pump. When you are ready to tune, we have calibration data and tuning guides available to your dealer, installer, or tuner. We do not recommend driving or starting the vehicle without a tune. \u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eQ: Will this work on my E9x N55 or N55 with an N54 style pump?\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003eOur HPFP is NOT compatible with the early N55’s that had the N54 style HPFP.
