This Dinan low temp radiator for the S55 turbo straight six massively improves thermal management so your M car pulls hard run after run, on the road, on the dyno and on circuit. If you are chasing consistent performance, faster recovery between pulls and repeatable power in hot conditions, this upgraded charge cooler water radiator is the proven answer.\u003c\/p\u003e\n\n  \u003ch3\u003eWhy it belongs on every F8x\u003c\/h3\u003e\n  \u003cp\u003eThe factory charge cooling system can get overwhelmed during repeated wide open throttle. Once intake temperatures climb, the ECU trims ignition advance to protect the engine and you feel the pace drop off. Dinan’s uprated low temperature radiator increases coolant capacity and heat rejection so the S55 stays in its ideal window for longer, delivering crisp, reliable acceleration without the usual heat fade.\u003c\/p\u003e\n\n  \u003ch3\u003eProven technical gains\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eApproximately 60 percent increase in coolant capacity for the charge cooling circuit.\u003c\/li\u003e\n    \u003cli\u003eAbout 19 percent more frontal area for improved heat exchange.\u003c\/li\u003e\n    \u003cli\u003e40 mm core thickness, chosen to maintain airflow to the primary engine radiator.\u003c\/li\u003e\n    \u003cli\u003eAverage 9° reduction in water temperature feeding the charge cooler across the rev range.\u003c\/li\u003e\n    \u003cli\u003eAverage 6° drop in intake temperature across the rev range.\u003c\/li\u003e\n    \u003cli\u003ePower gains of up to 10 bhp and 20 lb ft without calibration.\u003c\/li\u003e\n    \u003cli\u003eUnlocks additional performance when combined with DINANTRONICS Stage 3.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eReal world results\u003c\/h3\u003e\n  \u003cp\u003eIndependent testing shows stock setups heat soak after only a few consecutive pulls. With the Dinan low temp radiator fitted there was no heat soak even after seven back to back runs. We have installed and used this upgrade on customer F8x cars and the feedback has been outstanding for daily use, spirited B-road driving and track days.
