Air Intake Temperatures & Heat Soak
Intake temperatures were tested on the stock intake system by placing thermocouples before the air filter on both the OEM and Infinity systems.The OEM system manages ambient temperatures as low as 20mph and immediately under full load. Under full load high rpm acceleration the ambient temperatures remains at ambient. In terms of temperature, the OEM system sets the benchmark.WIth the Infinity intake fitted without the front snorkel intake temps are consistently + 5-10 degC higher than OEM. With the snorkel fitted, the air air is being taken from the exact same area as OEM and therefore the Infinity system matches the OEM efficiency.
Air Filtration
Within the beautifully shaped carbon shaped enclosures sits our bespoke short stack high surface area filter larger than any cone filter design currently on offer on the market with a huge opening of 170mm (6 3/4″) and is designed to take full advantage of the intake tubes by altering the direction of the airflow towards the outer walls.
By placing the air filters in front of the inlet tube we achieve the largest velocity stack ever seen for the FA24 engine and which also has the best laminar flow. It is important to note that we have painstakingly opted for the largest possible air filter for a various number of reasons. Not only does a larger air filter allow for more air flow and therefore power but it also does not block up for longer and continues to be efficient at it’s main purpose which is to filter the air of harmful elements.
Dyno Testing – +10-12HP | +5-10lb.ft
Dyno tests were performed under strict controlled conditions on an independent Maha MSR500 dynamometer in order to show a true and realistic result.
The stock car made almost exactly what the manufacturer quotes with 228 BHP and 179 lb.ft torque with a perfect power curve.
After fitting our intake system the peak power went to 239BHP and 184 lb.ft torque.
A significant and clear gains of 11 BHP and 5 lb.ft torque peak.
From 2000-3000rpm a torque increase of 10 lb.ft was gained which is a significant gain.
From 6000rpm onwards the FA24 engine gains significant HP and torque to the red line.
Run down losses remains identical between the two tests as did the ambient temperature.
Both sets of tests were carried out with identical starting oil and coolant temperatures.
Dyno Line Key:
Solid Blue line / Dotted Blue Line – WHEEL HP
Solid Green Line / Dotted Green Line – Drivetrain Loss
Solid Red Line / Dotted Red Line – Flywheel Calculated HP (wheel + loss)
Solid Yellow Line / Dotted Yellow Line – Flywheel Calculated Torque
