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.

This is a complete plug and play solution to replace your stock Low-Pressure Fuel Pump (LPFP) with a new E85 certified bucketless assembly.

This solution provides up to 25% more flow than our standard Stage 2 LPFP upgrade and up to 150% more flow than the stock pump.  

This pump will support up to 550whp running 85% ethanol and 600whp running 50% ethanol. 

The Stage 2 bucketless kit includes the following:

    • A custom anodized billet fitting for the pump output and stock fuel line connection.
    • Our custom billet aluminum anodized bracket for the pump and float assembly
    • Two cotter pins to secure your float assembly
    • A new E85 compatible Walbro 450 pump
    • Spare vent tube clip
    • A new Walbro filter

If you still need more flow, the Stage 3 upgrade is also available and can be added to your Stage 2 bucketless pump.

The Stage 3 upgrade kit includes:

    • A complete plug and play solution by simply adding the secondary module
    • Our custom billet aluminum fitting to run both pumps in parallel
    • A new E85 compatible Walbro 450 pump
    • Wiring harness for the secondary pump
    • Spare vent tube clip
    • A new Walbro filter
  • Recommended accessories:
    • Lock Ring Removal Tool
    • Hobb's switch 
       
  • NOTE: These kits include a basic filter assembly.  When using this filter, running the vehicle under low fuel conditions can cause fuel starvation issues. If you do hard straight line accelerations when you have less than 1/8 tank of fuel, we would recommend running our standard Stage 2, 3, or Stage 4 pump.  In addition, if you intend to use this for road course applications, you may see starvation issues when running less than a half tank and doing long high G right turns.  Again for those applications we'd recommend one of our standard pump applications.

These kits are designed to be installed inline with your stock low-pressure fuel pump (LPFP).  They provide approximately 50% more flow when combined with your stock pump.

Kit includes the following:

  • SAE J30R10 E85 compatible fuel line
  • 14ga fuel resistant wiring harness
  • Quick connect female bullet connectors (2)
  • Vent tube replacement clip
  • Nylon cable ties (10)
  • Stainless steel lock nuts (2)
  • 10ga/14ga step-down butt splices w/E85 compatible heat-shrink tubing (2)
  • Pushlock pump retention fittings (2)
  • 14ga butt connectors w/heat-shrink tubing for pump removal to return to stock if/when desired (2)

    *Note:  Walbro does not warranty this pump for E85 use.  If your application requires an E85 certified pump you may want to consider selecting a Stage 2 fuel kit.

    ** IMPORTANT:  Do NOT attempt to run this kit inline with a Stage 2 kit.  The Stage 2 kit is a higher flowing kit and this will not only restrict the flow of the stage 2 kit, it will result in failures.
