Description

We have found the stock High Pressure Fuel Pump (HPFP) can not flow enough to run full E85 past with any power mods past stock. You can run full E85 with a upgraded intercooler and air intake but may be limited on power. 


Check out our Mods Guide to see dyno graphs of power outputs and for a good mod path for future modifications.


Pump Gas Typical Gains

  • 300-320+ hp to the wheels!
  • +50 hp (22%) increase in horsepower over stock
  • +95 ft/lbs (43%)  increase in torque over stock

Ethanol (E40-E85) Typical Gains

  • 320-380+ hp to the wheels!
  • +95 hp (42%) increase in horsepower over stock
  • +120 ft/lbs (55%) increase in torque over stock

Why E40

E40 is an easy way to run ethanol; you just put a 50:50 mix of E85 and 91/93 when you refuel. Even with varying ethanol content at the pumps of 60-85% you will always end up with the fueling being within + or – 3%. Since the 2022+ WRX is full time closed loop it will correct the fueling even under full throttle so it’s always spot on.
