Aeromotive Stealth 340 Fuel Pump for RX-7

High flow pump with none of the annoying noises of many hi flow aftermarket pumps.
Essex Rotary are proud to bring you the Aeromotive Stealth 340 Fuel Pump, These pumps will fit in the same location as your failing OEM pump deliver considerbly more fuel while still retaining an almost factory spec like sound level (no more annoying pump whine when you need more fuel)
AeromotiveStealth340FPump270px
The Aeromotive 340 Stealth Fuel Pump is a high-output, in-tank, electric fuel pump that fits most popular EFI applications. The Aeromotive 340 is a compact, lightweight pump that bolts into many existing hanger assemblies.
What sets the 340 Stealth Pump apart is its superior flow throughout a wide pressure range. Compared to other popular aftermarket pumps, at 40 psi the 340 boasts more than 340 lph. That’s over 30% more flow. This pump is ideal for applications requiring more flow while retaining the factory lines and mounting provisions available in the Original Equipment (O.E.) configuration. The 340 is also perfect for use as a universal replacement for applications that require more flow to support forced air power adders such as turbo and supercharged applications.
We have been running this pump in our own cars for a few years now with excellent results and no drop in fuel delivery.

Black Halo Racing Flywheel

Exclusive to Essex Rotary in the UK.
Offering the lightest streetable flywheel on the market worldwide, BHR lead the way in product innovation.

BlackHaloRacingFlywheel420px
When it comes to your powertrain the flywheel can be a limiting factor due to it’s mass.  While at slightly less than 17 lbs. the RX-8 has a lighter flywheel than most production vehicles, Black Halo Racing has gone further to develop a much lighter alternative.  Our 9 lb. aluminum flywheel removes rotating mass in critical areas allowing more power to be translated to the wheels (which is where you want it, isn’t it!).  Our flywheel also has a replaceable friction face allowing you to reuse/repair the flywheel (if necessary) instead of having to buy a replacement should the need arise.

Necessary counterweight is sold separately.
Optional discount if purchased with a counterweight, take a look at our special offers section for model options, Package price would be £525.00 collected or £545 Delivered

  • Ability to upgrade to direct fire operation (4 ignition coils)
  • Ability to upgrade crank trigger

Special Features

  • This ECU also supports all the functions of the 440 ECU, however for advanced functions such as traction control, additional wiring and/or sensors will be necessary:
  • Flex fuel function – fill it up with gas/petrol or any ethanol concentration
  • Adaptive fuel control (self tuning) – reduces dyno time
  • Traction control function
  • Serial input for wideband O2 sensors (we recommend the MTXL)
  • Serial output for communication with dashes and dataloggers (we recommend the Race Technology units)
