The thin core is easily overwhelmed with IAT's rising dramatically once pushed beyond a few successive WOT pulls or even a few minutes at the track. This elevation in temperature gives way to the factory ECU fail safes pulling timing and reducing overall power in order to keep the system from overheating to the point of permanent damage. On an application where enjoyment is directly attributed to pushing the platform to its limits this constraint to cooling presents a challenge for the automotive enthusiast.\u003cbr\u003e\u003cbr\u003eThe Dinan B4x\/B58 heat exchanger for the F2x\/F3x chassis assists in mitigating these issues with a more robust core (48mm thick Dinan core vs. 27mm thick OEM core) that wields 78% more heat transfer surface area for improved cooling capacity. The significant increase in core thickness requires unique \"L\" shaped end tanks to be incorporated as well, which also contributes to the overall thermal mass (ability to absorb, store, and release heat) improvement beyond the OEM setup. With up to a 15° IAT delta recorded over stock the Dinan heat exchanger is ready, and able, to assist in extending your vehicles ability to deliver maximum performance time and time again for your driving enjoyment!\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\n\u003ch2 data-mce-fragment=\"1\" class=\"title\"\u003eENDURANCE TESTING\u003c\/h2\u003e\n\u003cp data-mce-fragment=\"1\"\u003eCharge Air Temp Reduction, or Intercooler Temperature drop (Intercooler dT), is a measurement of the temperature drop across the intercooler (inlet temperature - outlet temperature). For this testing and data presentation, the measurement was taken at the end of each pull (~100mph WOT). The end of the pull was chosen as it generally represents the highest load on the charge cooling system. The charge cooling system has two parts, the intercooler and heat exchanger. The data shows that by implementing the Dinan heat exchanger, with the OEM intercooler, the charge cooling system pulls more heat from the intake air (lower IAT's) and performance decays slower (longer time on track before cooldown required).\u003c\/p\u003e\n\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cimg data-mce-fragment=\"1\" height=\"1409\" width=\"1999\" src=\"https:\/\/images.dinancars.com\/x\/d780-0002_data.jpg\" data-mce-src=\"https:\/\/images.dinancars.com\/x\/d780-0002_data.jpg\"\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eFeatures:\u003c\/h3\u003e\n\u003cul data-mce-fragment=\"1\" class=\"productpage_list\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eAverage of 8° reduction in IAT's with a maximum reduction of 15° over 15 successive WOT pulls\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eReduces the tendency to heat soak \/ go in to limp mode\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e48mm thick Dinan cooler vs. 27mm thick stock cooler\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e78% more cooling surface area and volume than stock\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e100% TIG welded and pressure tested\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eInstallation hardware included (inclusive of xDrive specific transmission oil cooler brackets)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Dinan","offers":[{"title":"Default Title","offer_id":43982551253154,"sku":"D780-0002","price":836.81,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0527\/9953\/7314\/files\/667c99ad0231de77769b48779c69c238b4e9476d.jpg?v=1705698047","url":"https:\/\/broxtuning.ca\/products\/dinan-high-performance-heat-exchanger-bmw-f2x-f3x-230i-m240i-330i-m340i-and-more-d780-0002","provider":"Brox Tuning","version":"1.0","type":"link"}
