Not sure how they can state their "opinion" that it's more robust and reliable than a brushless motor. It's my opinion that flying coach is better than flying business class or private charter.

Dunno Bosch doesn't advertise it's pumps but it well know the dw400 is a rebranded Bosch pump. Thing is that 540 lph is open flow, you're not going to use a pump like that it has to at least be rated at 3 bar, which is a more apples to apples comparison. Hell my fuelab pumps can do like 700 lph open flow but it doesn't mean much.

  • Complete 1500 hp Fuel module / direct replacement fit
  • Electronically controlled pre-programmed PWM System
  • Integrated 4 Venturi Pumps with refill valve system
  • Internal design fuel pressure regulator
  • 2x high performance Bosch Racing fuel pumps
  • High flow canister, distribution manifold and fittings
  • Easy fit high amperage wiring/connector kit
  • Supports standard power and up to 1500 hp
  • NO surge in all conditions and fuel levels
  • Eliminates the need for voltage boosters
  • Eliminates the need for return style systems
  • Eliminates the need for surge tank systems
  • Cool dense fuel creating extra power and economy
  • Optimum pump life
  • 100% compatible on all fuels including E85 Ethanol
  • Easy hassle free fitment
  • Fitting and calibration instruction included


KPM 1500 hp Fuel Module

The KPM 1500 hp Fuel Module is engineered utilizing 2 x high performance Bosch Racing fuel pumps, all housed in an OEM style high-flow fuel canister and distribution manifold. The KPM fuel module is mounted and immersed in the vehicle’s fuel tank as per OEM design and for ease of fitment.

The development and testing of the KPM module was focused on supplying guaranteed delivery of cool, dense fuel to support 1500 hp at the engine on pump fuel. Our objective was also the supply of solid fuel delivery in both everyday road driving and extreme track conditions, regardless of fuel level in the tank

To achieve these objectives, our KPM Fuel System engineer designed and incorporated a four Venturi pump and refill valve system designed to scavenge fuel from both sides of the Mustang fuel tank and permanently keep the fuel canister full.

This means that you can run the KPM fuel module at any fuel level safely across all conditions without the risk of surge or fuel starvation, including during spirited driving, circuit days, or drag racing.

The fuel pumps are 100% gasoline, ethanol and methanol compatible and able to deliver massive amounts of cool, dense fuel at standard vehicle voltages.

This equates to optimum tuning and power levels up to 1500 hp (flywheel rated on 94 octane)

Controlling fuel pump current will keep fuel cool and dense preventing vaporization, retaining maximum energy for optimum power.

Advantages

  • Cool dense fuel
  • Prevent atomization
  • Full upgradable to run up to 4 pumps for future use
  • Prevents long cranking times
  • Maximum engine power potential
  • Repeatable and predictable engine performance
  • Ease of tuning
  • Extended fuel pump and fuel system reliability
  • Relieving the electrical system of excessive load
  • Extended long idling and driving periods
  • Provides maximum fuel system and engine reliability
Features

  • Direct plug and play fitment when used with KPM 1500 hp and 2200 hp Fuel Modules
  • Easy fitment with instructions provided
  • Pre-programmed settings to suit supported vehicle make and model
  • OE programmable when used on vehicles with a Factory Fuel System Control Module (FSCM)
  • 2 driver outputs at 40 amps each
  • Ability to run 1,2, 3, or 4 x high volume pumps
  • 4-gauge outputs 0-5v able to monitor e.g.: fuel pressure, temperature, pulse width, amperage
  • On-board temperature protection sensor
  • Everything provided for a hassle-free fitment

Less fuel pump current = less heat = cooler fuel = more power

Supplying fuel to support 1500 hp and beyond requires two or more high flow fuel pumps, housed in one or more in-tank fuel modules. The drawback to this scenario is that two or more fuel pumps can generate quite a lot of fuel pump current meaning increased heat.
This transfer of heat needs to go somewhere and therefore, heats the fuel in the tank.
This is generally not a concern however, if the vehicle is idling or being driven for long periods with a low level of fuel in the tank, the fuel may start to reach a point of losing its full energy potential or start vaporizing in the pumps or fuel lines. This can cause long cranking times and hard re-starts. In the worst cases, the fuel pumps will start to cavitate, lose pressure and not supply fuel as intended.

The KPM PWM controller is pre-programmed to monitor your vehicle fuel pressure across all engine loads which in turn allows the controller to calculate the required level of electrical current to your fuel pumps. This in turn delivers the correct amount of fuel to your engine as required in all conditions.
It sounds and looks like a great system?

Yeah that was my problem as well. The link. Is the only pump I could find similar , but 540 is open flow unfortunately and not 40psi+.

Nearly all pump manufacturers do this marketing trick. The flow is advertised in either free flow or the "typical" industry standard is 3 bar (which again, isn't sufficient to capture what the flow is at typical operating pressures, especially when boosted).

Looking at their product data, this is almost certainly a DW400 rebranded or extremely close to it. It flows around 380-390 gal/hour at 70 psi, which is right in line with most of the other pumps on the market, give or take a few units.
