With value of 1, turbo wont spool up to full boost before 4000 rpm, with value of 3, turbo will spool up almost instantly (if your turbo speed is set to high) at like 1500 rpm. For example, take and engine with 300 Nm 2000 rpm and 140hp 4000 rpm, which is your typical 2liter diesel. NOTE: What this will also do is, the higher this value is, the faster (meaning on lower rpm) and before your turbo will spool up. Sometimes it takes me a couple of hours of tweaking and testing to get the engine absolutely perfectly, because i really am serious about it. I use values 2,5 to 3 for turbocharghed petrol engines, about 2-2,5 for diesel engines, and 1-1,5 for atmospheric naturally aspirated engines, but again, it not fixed values, you have to play. If you want a V-tec type engine, with lots of power at high revs and less power on low revs, then use value like 0,5 to 1. What this will do is it will make your torque and power curves flat, if you know what i mean. If your engine will be something like a turbocharged petrol engine with really flat torque curve, you want a higher value, like 2,5 or 3, and then work other values after this. When making a engine, i suggest you first start with THIS value. The higher the value, smoother and flatter the torque/power curves will be. What this does is it flattens or sharpens the torque and power curves. So, lets say 0,2 value will have and 300Nm 2000 rpm, and 0,6 value will have and rpm.ģ) Power and Torque 3: This is to me a very important value, and will see why. The lower this value, the greater the distance between power and torque peak, and greater the ratio between power and torque gets, and vice versa.
The higher this value is related to others, the higher your power and torque are.Ģ) Engine and torque 2: this basically changes the distance between peak power RPM and peak torque RPM, and it increases overall torque of your engine, related to power.
