AMS designed the Omega Brushless Fuel Pump System to solve the fueling problems most GT-R owners have been plagued with for years. With over 2 years of extensive research and testing, culminating in the ultimate fueling solution for your R35 GT-R! Because of the complexity of this system a USB thumb drive is included with detailed installation instructions.

Why Is A Brushless Motor Better?

Brushed motor fuel pumps create heat due to the brushes rubbing against a commutator.  This rubbing wears away both the brushes and the commutator – making the fuel pump a wear item quite similar to your brake pads and rotors.  Additional heat is also generated by the pumping and pressurizing of fuel.  Since brushed fuel pump output is usually static based on the input voltage (battery voltage), the pump is running at 100% duty all the time. In any event, you have heat caused by the friction of the rubbing as well as more heat caused by the constant pressurization of fuel.

Contrary to this, brushless motors do not suffer from the friction and wear found on a brushed motor, nor do they generate the same level of heat. Not even close. That’s because nothing touches outside of a few bearings and it uses a controller to determine speed and output. The controller can lower output when less pressure is needed and increase output when more pressure is needed. The result is a significantly reduced fuel temperature. To ensure the best results, AMS Omega Fuel Pumps use OE quality brushless motors and automotive spec brushless controllers.

Lower Fuel Temperature To Save Your VR38 Engine  

One of the biggest problems your R35 GT-R has is the overheating of fuel inside your tank. The fuel tank already sits above a heat-soaked GR6 transmission and exhaust.  Having 2 or 3 inefficient brushed pumps inside the tank just adds to this problem.  We have seen fuel boil inside a GTR fuel tank with as little as 140° F ( 60° C).  When fuel boils, pump output drops dramatically – reducing the fuel supply to the engine.  Not enough fuel triggers a lean condition that causes detonation or extreme combustion temperatures hot enough to melt your engine components.

Screw Style Pump For Maximum Fuel Output In The Most Demanding Conditions

In line with the electrical motor, you have the mechanical side of the fuel pump.  This is what pumps / pressurizes the fuel.  During testing, we found that the style of the pump makes a huge difference in pumping efficiency, especially when the fuel temperature gets elevated.  Traditionally, a vane style or impeller style pump is used.  Unfortunately, with this style, fuel output can drop as much as 50% at higher fuel temps.  The Omega Brushless Fuel Pump uses a screw-style pumping mechanism that is practically immune to this phenomenon.

Super High Flow And Consistent Fuel Pressure  

All too often, standard fuel pumps suffer from pressure drop at higher fuel pressures. Our superior screw-style fuel pump maintains much higher pressure despite these harsh operating conditions.
