EVO 8 flex fuel build on Link G4X — 322 kW at the wheels

This 2003 EVO 8 was built for closed-circuit competition use, running a flex fuel setup on the Link G4X platform. The workshop paired Kelford 270 duration cams with an FP Green turbo to support the step up from 218 kW to 322 kW at the wheels, lifting torque from 320 Nm to 373 Nm. Boost increased from 1.5 bar to 2 bar, with hi/lo control allowing the driver to tailor delivery on track.

The Link G4X calibration includes rolling anti-lag for faster spool between corners and full monitoring for fuel pressure, lambda, oil pressure, and oil temperature. Flex fuel capability means the car can adapt between 98 RON and E85 depending on availability and ambient conditions. The 104 kW gain reflects the combination of hardware and calibration working together, with the G4X providing the resolution needed to manage timing, boost, and fuel delivery across different ethanol blends safely.

Common questions
What does flex fuel capability mean for this build?

The Link G4X ECU can detect and adjust calibration in real time based on ethanol content, allowing the car to run safely on anything from 98 RON pump fuel through to E85. This gives flexibility at the track and adapts timing and fuelling to suit whatever blend is available.

Why the step to 2 bar boost on this setup?

The FP Green turbo and upgraded cams provide the headroom to run 2 bar safely on E85, with the Link G4X managing boost control and monitoring. The hi/lo switchable boost allows the driver to dial it back when conditions or track layout don't suit full pressure.

Is rolling anti-lag suitable for street use?

Rolling anti-lag is designed for closed-circuit competition where reducing turbo lag between corners delivers a clear advantage. It's not intended for road use due to noise, emissions, and drivetrain stress.
