Spool Performance is a top name in the BMW Forced Induction industry. Their team of young and intelligent engineers pair their passion for the industry with a rich education background, which results in a high-quality enthusiast-minded products. Spool Performance's state-of-the-art upgrades for your BMW fueling systems are a surefire way to make more power, reliably. The Helix from Spool is simply a planetary gearbox for your High-pressure fuel pump. The particular configuration of the gears and their spatial fixturing allows an axial increase in shaft speed from the input to the output of the unit. The early N55 high-pressure pump is a very capable and over-engineered piece of hardware. As we start tuning and pushing more power, we start seeing drops in the high pressure. What is happening here is that the high-pressure pump is not able pump as much fuel as the injectors are injecting into the cylinders and hence causing the rail pressures to drop. The pump at this point is running out of displacement volume. With a rotary pump like the continental HPFP, an easier way to increase displacement is to spin the pump faster which results in an increased number of delivery strokes per cycle. The Helix helps you do exactly this and thus helps overcome a big limitation in early N55 fuel systems without the complexity of a secondary port injection system.
