EVOLVE | Eventuri Intakes - Last units available
As an Eventuri dealer we have existing stock ready to ship! These are the last units we have available in stock currently, and with stock generally on back order, we wanted to give customers the chance to order immediately.
2 Units Remaining: Eventuri Gloss Carbon Fibre Intake System for the E9X M3     Performance Gain Dyno: 8-10hp, 10-12ft-lb Performance Gain Road Dyno (Insoric): 16hp, 14Nm IAT Difference with Ambient: Stock 7.5C: Eventuri 4.5C V-Box Acceleration: 100-200kph Reduced By 0.3 Seconds The BMW E90 | E92 | E93 M3 Eventuri intake system is the result of extensive research and optimisation which improves possibly one of the best designed stock intake systems we have seen. The E9X stock airbox system is a brilliantly designed intake with an excellent flow path and feed system for ambient air. However on closer inspection, there are restrictions in the inlet tube connecting the airbox to the inlet manifold. By redesigning the tube yet maintaining the airbox, we have been able to allow the V8 engine to breathe with greater efficiency and therefore gain power. In addition to the new tube design, we also identified a further restriction in the air feed system. To overcome this, we designed a scoop to allow an increase in airflow through the airbox. This reduces inlet temperature values further and adds to the performance gain of the system. Performance Gain Dyno: 8-10hp, 10-12ft-lb Dyno tests were carried out showing a consistent gain of approximately 9hp and 11ft-lb of torque. The gain is not just at the peak but throughout the RPM range. This translates on the road to increased part throttle and full throttle response with the car pulling much more eagerly to the redline. The testing was done on the same day back-to-back and temperatures were monitored to ensure consistency. The car was tested firstly with the stock intake - hood closed. We then left the car on the dyno and installed the Eventuri. The car was then run again - hood closed. Several runs were carried out with both configurations to get a consistent result. Performance Gain Road Dyno (Insoric): 16hp, 14Nm The system was also tested using a road based measurement device (Insoric). On the road, the airflow is a lot better than the fan can achieve on the dyno and so the intake system is able to perform better. Data Logging Flow and Inlet Temperature To monitor and record data output from the ECU we used a Bavarian Technic diagnostics tool. The car was fitted with the stock system and then data was logged in 4th gear to the redline. Then the Eventuri intake was fitted and the same method applied. The outputs show that the air mass flow with the Eventuri is higher across the entire RPM range - with a bigger difference at higher RPM where the restrictions in the stock system become more apparent. Furthermore the difference between the ambient temperature and the inlet air temperature (IAT) is also smaller with the Eventuri due to the scoop enabling a higher air speed through the airbox.
VBox Acceleration Tests We also took the car for some road testing using a Vbox unit to record the acceleration from 60-130mph (also 100-200Km/h). Testing was carried out on the same stretch of road - again on the same day to keep variables minimum. Results show that with just the intake added, the acceleration times from 60-130mph and also 100-200Km/h reduced by approximately 0.3 seconds which is a significant change at such speeds. Acceleration results summary: 60-130mph with Stock intake = 11.157 seconds 60-130mph with Eventuri intake = 10.886 seconds 100-200Km/h with Stock intake = 9.56 seconds 100-200Km/h with Eventuri intake = 9.236 seconds PM me for details |
