We use 100% pre-preg carbon fiber with no fibreglass which means we can achieve a smooth internal surface to maintain smoother airflow. Here are the details for each component and the design ethos behind them:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEach Turbo Tube Set consists of:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCarbon Fiber Turbo Tube\u003c\/li\u003e\n\u003cli\u003eCNC Machined Turbo Flange\u003c\/li\u003e\n\u003cli\u003eCustom Nitrile Hose\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCarbon Fiber Turbo Tube\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe main tube body is crafted from prepreg carbon fiber. This allows the inside to be smooth which helps maintain laminar flow. The tube incorporates an OEM style mount to secure it to the engine as well as the breather ports for a plug and play installation. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComparison with OEM\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhen comparing the 2 tubes side by side, the most significant increase in volume can be seen at the elbow which leads to the turbo. The OEM tube is heavily restricted in this region and this leads to a choking effect, particularly at higher boost levels. In contrast, our tube has been enlarged significantly in this region while at the same time we have optimised the bend radius for a smoother flow path to the turbo. The result is a two fold increase in the availability of encapsulated air which improves throttle response. Furthermore with less restriction, peak boost can be reached sooner. \u003c\/p\u003e\n\u003cp\u003eAs can be seen, the increase in volume from from 1,300cm³ to 2,200cm³ represents an increase of almost 70%.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComparison with OEM\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe OEM tube is in a brass colour and the Eventuri tube has been made transparent. You can clearly see the regions where we have increased volumes and improved the flow path.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eConnecting Hose\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe carbon tube connects to our custom designed hose made from Nitrile and reinforced with ribs to withstand vacuum forces. This allows for an easier install where the elbow can be installed prior to the carbon tube. This hose provides a smooth internal surface with internal steps to allow for a seamless transition between the carbon and the machined turbo flange.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTurbo Flange\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFinally our CNC machined turbo flange secures to the turbo and completes the flow path. This flange can be replaced with alternative versions we will provide separately for larger turbos. \u003c\/p\u003e\n\u003ch3\u003ePerformance\u003c\/h3\u003e\n\u003cp\u003eIndependently dyno tested at a GR4 specialist – Limit+1, our turbo tube shows gains at the wheels of 14whp and 19ft-lb in the lower rpm range which is a result of the larger volume of immediate air available in the tube. At the higher rpm there are gains of 9whp and 9ft-lb. \u003c\/p\u003e\n\u003cp\u003eThe tube was tested on a GR Corolla with a stock ECU. The baseline runs were carried out with an Eventuri intake and the OEM turbo tube. After several runs, only the OEM turbo tube was swapped out for our version. Nothing else was changed on the engine. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eVehicle Fitment\u003c\/em\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003ctable style=\"width:100%;border-collapse:collapse;margin:0 0 1em;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding:6px 10px;border:1px solid #ddd;background:#f5f5f5;text-align:left;font-weight:600;\"\u003eMake\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px;border:1px solid #ddd;background:#f5f5f5;text-align:left;font-weight:600;\"\u003eModel\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px;border:1px solid #ddd;background:#f5f5f5;text-align:left;font-weight:600;\"\u003eChassis\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px;border:1px solid #ddd;background:#f5f5f5;text-align:left;font-weight:600;\"\u003eModels\u003c\/th\u003e\n\u003cth style=\"padding:6px 10px;border:1px solid #ddd;background:#f5f5f5;text-align:left;font-weight:600;\"\u003eYears\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003eToyota\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003eGR Yaris\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003eGXPA16\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003eAll models\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003e2020–2026\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003eToyota\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003eGR Corolla\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003eGZEA14\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003eAll models\u003c\/td\u003e\n\u003ctd style=\"padding:6px 10px;border:1px solid #ddd;\"\u003e2023–2026\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Eventuri","offers":[{"title":"Default Title","offer_id":55358914724181,"sku":"EVE-GR4-CFM-CHG","price":612.0,"currency_code":"GBP","in_stock":true}],"url":"https:\/\/shop.regalautosport.com\/products\/eventuri-toyota-gr-yaris-corolla-carbon-turbo-inlet-tube-matte","provider":"Regal Autosport","version":"1.0","type":"link"}
