However, it does lack something and this is evident from just hearing the engine under normal driving and looking under the engine bay. The intake sound is mostly artificial being driven into the car by the speakers and it is very small with a series of Helmoltz resonators which quieten the induction sound.\u003c\/p\u003e\n\u003cp\u003eThere is also a distinct hesitation at the lower rpm’s (not the mild torque dip).Our aim was to vastly improve the intake with a full redesign to give faster throttle response, improved torque under both partial load and full load and most of all more induction sound. The Toyota GR86 is the least powerful car we have ever developed an intake system for but it’s been the most rewarding.\u003c\/p\u003e\n\u003cdiv class=\"section__title section__title--mb-s js-animate-single js-animation-done\" data-animation-displacement=\"5\"\u003e\n\u003ch2 class=\"section__title-text\"\u003eDEVELOPMENT PROCESS\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"custom-content__item-text rte\"\u003e\n\u003cp\u003eDuring the development process we created multiple prototypes.  The initial prototype used a straight venturi tube feeding into a large airbox which took it’s air from the stock OEM area with an enlarged area with an additional air feed on the opposite side which is very small.The idea was that the additional air feed would help in increasing available airflow.  However this design failed to give the desired results both on the dyno testing and on the road with no difference in power. Drivability was compromised with an additional torque dip in the higher midrange.  CFD analysis showed vast amounts of turbulence in front of the air filter.\u003c\/p\u003e\n\u003cp\u003eIn order to keep the airflow smooth and uniform the direct approach was taken with the same path with the single feed but with the following major changes: \u003c\/p\u003e\n\u003cp\u003e1 – Double the cross sectional area of the front inlet feed giving more a more than adequate increase on available air for the FA24\u003c\/p\u003e\n\u003cp\u003e2 – Extend the snorkel towards the front and incorporate a bell mouth to smooth the air flow\u003c\/p\u003e\n\u003cp\u003e3 – use a significantly larger air filter housing and the largest possible venturi inlet tube.\u003c\/p\u003e\n\u003cp\u003eAfter some iterations this method gave the best air flow under CFD analysis showing less turbulence than the OEM system with vastly increased airflow. \u003c\/p\u003e\n\u003cp\u003eThe results on both the dyno (see below) and road driving were excellent.  Vastly improved throttle response, low end torque response improvements with all of the hesitation now absent.  At mid-higher rpm heavy load driving a clear gain in performance noticed. Under normal but spirited driving the engine feels even more eager to accelerate in the 2000-4000rpm range required with more torque.\u003c\/p\u003e\n\u003cdiv class=\"section__title section__title--mb-s section__title--center js-animate-single js-animation-done\" data-animation-displacement=\"5\"\u003e\n\u003ch2 class=\"section__title-text\"\u003eHigh Flow Air Filters \u0026amp; Intake Temperatures\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"custom-content__item-text rte\"\u003e\n\u003cp\u003eOur 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.\u003c\/p\u003e\n\u003cdiv class=\"section__title section__title--mb-s js-animate-single js-animation-done\" data-animation-displacement=\"5\"\u003e\n\u003ch2 class=\"section__title-text\"\u003ePERFORMANCE TESTING\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"custom-content__item-text rte\"\u003e\n\u003cp\u003eDyno tests were performed under strict controlled conditions on an independent Maha MSR500 dynamometer in order to show a true and realistic result. \u003c\/p\u003e\n\u003cp\u003eThe stock car made almost exactly what the manufacturer quotes with 228 BHP and 179 lb.ft torque with a perfect power curve.\u003c\/p\u003e\n\u003cp\u003eAfter fitting our intake system the peak power went to 239BHP  and 184 lb.ft torque.\u003c\/p\u003e\n\u003cp\u003eA significant and clear gains of 11 BHP and 5 lb.ft torque peak.\u003c\/p\u003e\n\u003cp\u003eFrom 2000-3000rpm a torque increase of 10 lb.ft was gained which is a significant gain.\u003c\/p\u003e\n\u003cp\u003eFrom 6000rpm onwards the FA24 engine gains significant HP and torque to the red line.\u003c\/p\u003e\n\u003cp\u003eRun down losses remains identical between the two tests as did the ambient temperature.\u003c\/p\u003e\n\u003cp\u003eBoth sets of tests were carried out with identical starting oil and coolant temperatures. \u003c\/p\u003e\n\u003ch3 class=\"image-grid__title\n                              image-grid__title--adapt-border\n                              h2\"\u003eWhat is in the Box\u003c\/h3\u003e\n\u003cdiv class=\"image-grid__desc rte\"\u003e\n\u003cp\u003e1 x Venturi Inlet Tube\u003cbr\u003e1 x Air Filter Housing \/ Inlet Duct\u003cbr\u003e1 X Snorkel\u003cbr\u003e1 x Bespoke Infinity Design Air Filter\u003cbr\u003e1 x Black metal clamp\u003cbr\u003e1 x Silicone Joiner with Clamps\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"ARG Performance","offers":[{"title":"Gloss","offer_id":57919485509957,"sku":null,"price":1050.0,"currency_code":"GBP","in_stock":true},{"title":"Matte","offer_id":57919485542725,"sku":null,"price":1050.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1989\/9461\/files\/Gr86IntakeExploded.webp?v=1778507196"}],"url":"https:\/\/argperformance.com\/collections\/intakes.oembed","provider":"ARG Performance","version":"1.0","type":"link"}
