![]() ![]() It compares the average charge air temperature relative to specific air intake temperature at different speeds. Below is data from a full day of off-road racing. For that reason, we also explored some real world testing. Real world conditions can sometimes vary with what is produced in a dyno cell. These two pulls were made the same day in 95 degree ambient air temperature. This maintains a 92% or better intercooler efficiency up to redline! This is a substantial difference in the reduction of charge air temperature which offers a great deal in performance gains. Here we see the COBB FMIC in action! Although the intercooler outlet air temp does rise a little, it peaks out at only 107 degrees Fahrenheit. This starts a sharp rise in charge air temperature that continues to increase dramatically all the way to redline capping at 199 degrees Fahrenheit. But, the heat generated as Boost and RPM rises quickly overcomes what the incoming air can cool through the stock FMIC. This is due to the increased airflow over the intercooler. There is an initial drop in the temperature as wide open throttle is applied. ![]() The data above shows the intercooler outlet air temperature with the stock FMIC in green. Let’s examine the efficiency of the stock FMIC compared to the COBB unit during a single pull on the dyno. This same issue is present with the Raptor FMIC. With other ecoboost vehicles, the stock FMIC quickly succumbs to heat soak greatly sacrificing performance. Its function is to cool the charged air coming from the compressor side of the turbo prior to it entering the intake manifold. The intercooler plays a crucial role in any turbocharged gasoline powerplant. Efficiency is the name of the game and this intercooler will get the most out of your stock turbos and still has plenty left over for future upgrades to go along with it. Straight forward installation requires minor trimming on the back side of the grille and maintains the factory Adaptive Cruise Control bracket when using the stock bumper.Ĭombined with an Accessport, upgrading the stock intercooler is a no brainer as the best bang for your buck modification on a F-150 Raptor. The much larger 24" wide x 14" tall x 3.5" thick core produces a significant volume increase compared to stock, resulting in minimal pressure drop despite the significant increase in size. Adjusted ignition timing, torque modeling, torque targets, boost control (including overboost), camshaft phasing (VCT), and base programming logic.The COBB Front Mount Intercooler (FMIC) for your F-150 Raptor is the easiest way to drastically improve power when coupled with tuning from the V3 Accessport. Original release calibration for Stage 1 maps. Original release calibration for Stage 2 maps fixed bug related to Auto Stop/Start in Stage 1 maps Improvements made to boost control at higher elevations and part throttle power delivery Original release calibration for 2019 Raptor Stage 1 maps improved power demand pedal translation Revised boost control at high RPM for 2018 Raptor Stage 2 maps all other maps unchanged and adjusted for version number parity Original release calibration for 2020 Raptor improved power at higher charge air temperatures on 2019 Stage 1 93 OCT map Maps have been updated to eliminate unnecessary DTC suppression. Initial release of Performance Tow calibrations. Knock Octane Modifier and Coolant Temperature are both parameters the Accessport can monitor.Ĭomprehensive evolution of original OTS improved power/torque consistency over a wider range of operating conditions, improved driveability.This is to prevent heavy load in the case the vehicle begins to overheat due to a mechanical failure. Knock Octane Modifier (KOM) will be limited to -1.0 while Engine Coolant Temperature is above 250*F (121*C) on COBB OTS maps.Limiting Knock Octane Modifier during warm up is done to prevent unnecessary strain before the engine has reached a reasonable temperature. It is common to see a KOM of 0 when the vehicle is warming up. By 135*F (57*C), KOM will return to the retained learned value if it is greater than 0. Knock Octane Modifier (KOM) will be limited to less than or equal to 0 while Engine Coolant Temperature is below 130*F (54.5*C) on COBB OTS maps.Ideally this value should be at +1.0 but it can change depending on conditions other than knock. The lower the KOM the less the power output. KOM can dictate how much load, boost, ignition timing, etc. Knock Octane Modifier (KOM) is a learned variable that will change dependent mainly on knock corrections over time. ![]()
