3400HP From ONE Pump! | What Do YOU Know About Brushless Fuel Pumps? [TECH NUGGET]

September 5, 2019

– Providing enough fuel for a very high
power race engine is obviously challenging. And we’ve probably all seen cars equipped
with fuel systems consisting of multiple fuel pumps mounted in surge tanks
and fuel tanks making sure that the engine has sufficient fuel to remain safe and
reliable under high power operation. Now the problem with this is when
you are faced with multiple pumps, it provides complexity both in the installation
as well as the ability for more parts to go wrong. Basically we’re opening ourselves up for
more potential areas for failure. Now a technology that certainly isn’t
new but one that we’ve been seeing emerge over the last few years is the
use of brushless fuel pumps. Now there’s still only a handful of
manufacturers supplying brushless fuel pumps and controllers out there
on the market but the technology really is impressive, particularly with the
capability of these pumps. The pump that most people are using
is generally referred to as the Veyron pump but the pump itself is not the tricky
bit. In order to use a brushless fuel pump,
this requires a specialised controller, and that controller is utilised to control
the fuel pump speed. Now the advantages of the brushless
pump compared to a conventional fuel pump is that with a conventional
fuel pump, as we increase the fuel pressure we tend to see the flow
out of the pump drop away. And ultimately this is exactly what
we don’t want to happen. Particularly if we’re considering a
high boost turbocharged or supercharged engine. As the boost pressure increases
we need to also increase the fuel pressure to maintain a consistent
differential pressure across the fuel injectors. Now of course as we increase the boost
pressure the pump finds it harder and harder to flow fuel and we see
that fuel flow drop away and if it gets to a point where the fuel flow
drops too far, we consequently see the fuel pressure drop. On a brushless pump on the other hand,
the controller has feedback for the actual pump speed. And this is what the controller is doing. It’s controlling that fuel pump speed
and maintaining a fixed speed. What this means is that within the
bounds of the pump’s capability we’re actually going to see a consistent
fuel pump supply, fuel volume supply, regardless of the pressure that we’re
putting on that fuel system. Now in the case of the pump that we’ve
got behind me developed by Injector Dynamics, this single Veyron
pump is capable of supplying an insane 1100 litres of fuel flow per hour
at 110 psi. So to give you some numbers around
that, on pump fuel this would equate to somewhere in the region of about
3400 horsepower of fuel flow capability. If you’re running E85 this drops to around
about 2200 horsepower. Just to remind you, that is from one
single fuel pump. So this is something that we’re definitely
going to see making its way into a lot of high end turbocharged and supercharged
cars over the coming years as these systems become more and more available. Now while this system has the ability
to flow up to 1100 litres per hour, of course we’re not always going to
need that amount of fuel, and if you’re running this pump as
hard as it’s capable of running, and you’re not using that fuel,
what it means is that you’re circulating a lot of fuel unnecessarily through the
fuel system and what this does is it adds heat to your fuel. Now with the Injector Dynamics fuel
pump controller, this also has the ability to take input from an ECU and
basically what we can do is control the input of the fuel pump as the
engine’s fuel demands increase. What we can do essentially is run the
pump at low speed at idle and cruise where we don’t really use much fuel,
and then as the boost and RPM increases we can drive the pump
harder and harder. It is also important to note that when
we’ve got this pump on maximum kill producing 1100 litres of fuel flow
per hour, at 110 psi, it is drawing a very large amount of
current. Somewhere in the region of 70 to 80
amps. While it’s unlikely that a brushless pump
and controller is going to be a cheap option for your fuel system, when you
compare this to potentially three, four or five separate pumps along with
installation and wiring of those pumps, and the reliability problems that come
along with this, it does look like a very attractive option for a high performance
high power engine. If you liked that video,

    mechanical pump > this thing

  • Reply hahaha no February 21, 2019 at 12:10 am

    What you describe is not a matter of brushless vs. brushed but of system design & intent, pump design, controller required (if any), etc. In short, your premise is incorrect.

    Additionally, more parts is not necessarily less reliable and if considered at a system level is likely more desirable as it will reduce the possibility of catastrophic failure should as compared to a single point of failure system (like the one being advertised) suffers from any degradation.

    As impressive as this is Im wondering if its worth the trouble as opposed to a engine mechanical fuel pump. Especially at those power levels.

    Mechanical fuel pump ran off the intake cam wheel for a 2JZ or RB. You can run a mechanical pump off the serpentine belt on a V8 or any other engine

    If Brushless motors can make rc cars do 120mph than I'm sure they can do some crazy stuff for fuel pumps.

    the potential to produce much more power and eliminate valve train failure for extreme performance engines is just around the corner.
    For a few years now, Koenigsegg has been testing a digitally controlled and operated intake and exhaust valve head that promises innumerable advantages with NO downsides, and NO compromises for mild to extreme motor applications…truly remarkable. truly revolutionary!
    The ‘FreeValve’ head will soon be on some of Koenigseg cars.
    The potential to drastically increase flow without compromise or reliability is truly the holy grail of performance engines.
    Typically, incremental improvements in materials and technology help improve performance and reliability. This technology on the other hand is a giant leap forward…an absolute game changer. Operates all day long at 15,000 rpm etc etc. watch video below.
    Would be interesting If this channel could do a video on the application of this technology for high performance applications…

    This makes life super easy for high output power units utilizing a non-return system, PWM control strategies using H-bridge controllers on traditional pumps wasn’t exactly on my top ten things I enjoy most; looking forward to when these are available for consumer retail.

    you have staged fuel pump feed on stock evo ? ecu runs low voltage on cruise and under load secondary relay kicks in and increases pump flow

    could a after market ecu not control that pump directly? seems to me it could

  • Reply GordoWG1 WG1 February 21, 2019 at 12:18 pm

    Seems many people don't understand the basic concept – using the controller, the pump runs at that current ONLY when the engine is demanding that fuel flow and, as Andre pointed out, it can be reduced drastically when a low fuel volume and/or pressure (if referenced) is required. Sure, if you wanted to, you could run a permanent feed to operate at that current all the time, or use a simple staged current supply, but you would lose most of the benefits. I don't see why this product couldn't be scaled down as required and, if it comes to that, lower flow rate pumps and controllers are already commonplace – many aftermarket ECUs can even do it with PDMs without an expensive controller.
    Andre, I cannot seem to find any info' on this product on their web site, or elsewhere – I assume it is still in development and not a retail product yet? It is getting commonplace for race vehicles to use 16V electrical systems – do you know if the 80A is @12V, 14V, 16V, 18V or higher? [edit] I see it is approximately 12.2V – with higher voltage to the pump, can I assume the controller will reduce the current so the power draw Vs pressure.volume relationship is maintained? i.e. at a little over 16V, as would be easily maintained, the current would be around 60A for the same pump power?

    Sure, for the hard case 'street' and strip-only cars a mechanically driven pump may offer simplicity, but that pump will be operating at full volume ALL the time, even at idle! May not be the optimum choice, but they sure look the dog's bollocks!

    This new controller is a big deal. Yes mechanical pumps can be simpler but consider the following for a street car with a tank/cell in the back of the vehicle: Mechanical pumps attached to the front of an engine with a pulley can be difficult to prime and can occasionally lose fuel pressure as fuel has to make its way all the way from the back of the car to the pump in the front. Mechanical pumps are really good at pushing fuel out of them but they like to be gravity fed and in this configuration you're really going against gravity, especially when accelerating and the fuel has to travel forward to be fed into the mechanical fuel pump. This can be solved by having a smaller electric pump that sends the fuel forward to a surge tank, but this has its own complexities (more fittings/lines to leak, surge tank, etc.). The other option is to run a mechanical fuel pump at the rear of the vehicle with a cable drive. This is IMO the best solution but the issue here is that it's not very street friendly as the cable needs to be lubed often. Let's also not forget that you'll probably need to remove your OEM fuel tank(s) and run a fuel cell. This also means cutting up your trunk and you're likely to lose your fuel level gauge.

    Isn't the most common engine failure caused by running lean by either a tune,fuel injector or pump failure or inadvertently electrical failure causing low voltage to the fuel pump causing a low fuel pressure situation . Example that I'm running a competitive drag car or track car using an electrical pump if my alternator fails or a wire terminal comes loose ect my engine runs leans and my event is all but ruined by losing a motor ,If my alternator fails or wire comes loose on my mechanical pump equipped motor I'll be fine my car will just die on me and my motor is still ok and I solve a small problem and I'm back in the running

    How long until we get electrical pumps that can support DI conversions in place of a mechanical high pressure one?

    Also.. mixing units of measure…lol

    SOME schools of thought say warm fuel is better for atomization.

    Electric fuel pumps are trash, mechanical pumps are superior with a much longer lifespan and lower service life.

    The controller is a "fancyfied" ESC.. brushless are 3 phase motors so they won't work plug and play with a 12v DC system. You need a controller to convert to 3 phase
