When most of the "vehicle-enthusiasts" hear this term, i.e., "boost by gear," their facial impression rage up to the point of defining certain boost levels that one particular gear can accommodate. Unfortunately, that is just the tip of an iceberg, while the whole mountain is soaked deeply in the earth&800MM Round Long Tube Axial Fan Exhaust Fan39;s EGR. Let's change that fact today. What Exactly is Boost by Gear? The term revolves around the different amount of boost pressure that is abstained with the appropriate gear a motor is currently in. Doing this is important in a turbocharged vehicle, to gain better drivability in external or internal wastegate run systems. The motor of your vehicle sees the mechanical advantage provided by gears as an opportunity, and to control it, is the only option a tuner or driver must encapsulate to ensure optimal performance. It is accompanied with varying horsepower by the amount of boost pressure provided. How does it work? While setting up and tuning boost by gear, there is no way your wastegate is going to be controlled by transmission gear. [Although this option may be available in some high-end setups, otherwise, you simply wouldn't want to do that yourself!] Most of the vehicles, including yours, have separate vehicle speed sensors. Meaning that the wastegate solenoid is entirely governed by the speed of the vehicle instead of some meticulously pestered gear system [not directly at least]. Let's understand it with an example: Suppose your vehicle touches 38, 62 and 94 MPH in first, second and third gear respectively, now, as per the industry norms, you will see 5, 10, and 15 psi [all the way till 200 MPH] on a 52mm round gauge display. Now, the first look might suggest you that gears are controlling the boost pressure which can be falsified easily if only you wish to accelerate without downshifting at a particular gear. E.g., if you are going 41 MPH at 3rd gear and wish to pass a slower vehicle, then the boost pressure would still be at 10 MPH even when you are riding in third gear. Our Cortex EBC is a high-performance electronic boost controller that also regulates water and methanol injection. Using external or factory waste gate solenoid is entirely your choice, the # more ports, the lesser stiffness while riding. It is ideal for all sorts of rally racing conditions, be it snow, cross, rally, drag and is made to control up to 50 psi boost pressure at each gear along with rpm, intake air temperature, failsafe flow sensor, throttle position, etc. Combine it with Peace keeper intercooler to minimize heat soak and maximize drivability.
