Description: Full set of DCN Performance Hood Louvers for Miata NB - NBFL Features:Very significant cooling improvement. See graph and track test details belowIncreased airflow even when car is stopped, greatly reducing air intake heatsoakingSpecifically designed for the NB Miata, according to negative pressure zones data collected from the NB Miata hoodMade from 2.5mm (0.1in) thick aluminium, and with durable black powder coatingGurney flaps included on all louver pieces. Gurney flaps increase the pressure difference and improve air extractionAll hood bracing is preserved. No cutting of hood bracing needed7 piece design covers a very large surface area, which allows much larger volume of air to move through than smaller hood louver alternatives.Air is vented out straight backwards and in line with the airflow of the car, NOT at an angle like other louvers in the market. Airflows colliding at an angle create vortexes and drag! What's included:Full 7 piece aluminium hood louver set, powder coated with a matte black textured finishBlack Aluminium rivetsFREE WORLDWIDE SHIPPING, using fast UPS and DHL services Track tests: Car used was a 270HP NBFL, turbocharged with IHI VF35 turbo on 1.8 VVT engine at 10:1 CR, with custom compressor wheel. Track used was Castelleto Circuit (2km track length), with environmental temperature of 26°C (78°F). The short track forces low speeds, putting even more strain on the cooling system.Results: Without louvers: Temperatures rise quickly and the car overheats on 3rd lap. ECU rev limiter at 4500 RPM is triggered for engine protection. After a cooling lap (lap 4) the car again quickly overheats on lap 5 and is forced to take cooling laps for the rest of the run. Minimum intake temperature recorded: 54°CWith louvers: Temperatures rise much more slowly, and stabilise below overheating limit. Temperature equilibrium of 103°C was reached on lap 6, after which temperatures remained stable for the rest of the run. Since temperatures never reached 105°C, ECU rev limiter was not triggered and the car was able to keep going at full power for the full run. Minimum intake temperature recorded: 43°C More track data will be posted as it becomes available. Testing will be continued in future track events If you wish to help with track data collection, contact us. This product fits second generation MX-5 (NB / NBFL)
