Dyno Testing
Dyno tests were performed under strict controlled conditions on a Dyno Dynamics machine in order to show a true and realistic result.
The first set of results show the best recorded stock run vs the best recorded run with the Infinity intake system and front air feeds.
15-25hp is gained through the rpm range with excellent gains below 3000rpm which can be attributed to the smooth elongated design of the intake tube which accelerates and smooths out the airflow. This gain is very much apparent under real world driving conditions under both partial and full load with a much smoother power delivery.
The next area where the expected majority of the improvements are seen are from 4750rpm to 7200rpm. The intake being free flowing and having a reducing cross sectional area improves airflow and therefore power where the oem intake becomes restrictive.
This is also translated under real world conditions with a harder surge to the red line.
Below is a further set of results showing the other dyno runs with the stock intake and Infinity intake.The F10 M5 is very sensitive on the dyno and can produce results which vary. Due to the S63TU engine being turbocharged, the charge temperatures can rise dramatically between runs. The engine management system will apply it’s compensation tables for increased charge, coolant and oil temperatures. Companies, their dealers and sponsors take advantage of this and show the lowest stock runs vs the highest runs with a modification fitted in order to exaggerate the gains for marketing and sales purposes.We are very much against showing these unrealistic gains as this is highly misleading.Below shows the results of multiple runs of the stock setup vs Infinity intakes fitted. If the lowest stock runs were used in our official results then a gain of approximately 35-40 hp could be shown which is not realistic of any intake system.
