Phase EX4-550 Mehrleistung bis zu +146 PS/+145 Nm Exige 4xx V6-Range
Product information "Phase EX4-550 Extra power up to +146 hp/+145 Nm Exige 4xx V6-Range"
Performance phase EX4-550
- Performance data EX4-550: approx. 552 hp / 585 Nm
- Standard performance data: approx. 406-436 hp / 420-440 Nm (factory specifications vary depending on model)
In addition to our EX530, our KT sport camshafts Phase 1, as well as reinforced valve springs with titanium spring plates, are installed in this phase.
Finally, we can offer our new 500+ power levels. In order to develop a perfect solution, it took the necessary time and a test phase of 2 years to finally be able to conclude with the use of our new Emu Pro16 control unit. The aim was not simply to call up ever higher performance data, but to completely redefine the concept in terms of stability and reliability and to complete it in peace, including the necessary test phase.
Contrary to the widely used method of simply generating additional power through increased boost pressure, Komo-Tec focuses on an increase in performance by optimizing the conditions of the overall system while minimizing mechanical and thermal stress. After extensive calculations, CFD flow simulations, various prototypes and numerous hours on the dynamometer, we were now able to produce a steadfast 530+ hp. After lengthy testing, we decided to continue using the Lotus factory-installed Edelbrock 1740 supercharger on the Exige 4xx models and optimize it to make it viable for the targeted performance. In order to ensure stability in the 500+ hp class, pistons, connecting rods and other relevant engine components are exchanged for those tested in racing. In the EX550 phase, sport camshafts are also used
The biggest difference to our previous EX kits is the change to the new, technically substantially advanced, freely programmable control unit "Emu Pro16". All standard functions of the vehicle can be retained and taken over (ABS/ESP, TC, Cruise Control...). The OBD functions are also fully functional. The use of two broadband lambda sensors guarantees perfect mixture preparation. After intensive development on the ECU and the associated coordination work, we can say that the suitability for everyday use is now on an absolute OEM level.
This ECU has also been successfully used in the Lotus Cup Europe and the experience we have gained there with our racing cars has also found its way into the further development of our conversions.
The EX4-550 phase is thus the second generation of a total of 3 power levels, which will reach up to 600hp in the future.
Key Benefits:
- significantly more torque (up to +145 Nm) and power (up to +146 hp) compared to the standard vehicle (based on the Exige 390)
