Forgive me if i am wrong, however i am under the assumption that since twin screw superchargers are connected with a belt to the crankshaft the psi is directly related to the RPM, and while some centrifugal superchargers do have a BOV, roots and twin screws dont. I just wanted to know if this was correct since the supercharger psi gauge reads 0 psi when you are not stepping on the gas.
Idle speed is probably so low that it can't make any boost, not to mention it isn't under load either. for clarification i have absolutely no idea what im talking about
i didn't meant idle speed, i meant just releasing the throttle. AFAIK even with the throttle closed a non centrifugal supercharger still makes the same amount of psi it would do if it was fully opened
Boost gauges show manifold pressure, after the throttle body. The gauge in game should actually show negative pressure at idle and low speed.
but dont IRL gauges read the pressure BEFORE the throttle body? i mean, if they didn't wouldn't it slightly hog the engine power?
Most boost gauges are before throttle body yes and then map sensors after. Twin screw and roots blowers in a hypothetical world that ignores parts tolerances, inefficiencies and some minor points of fluid mechanics should indeed have fixed boost across their entire rev range regardless of being on throttle or not. No idea why game reads zero except maybe the possibility the game is opening the clutch on the supercharger, the clutch that most don't have
I had already thought that the game likes to think about turbos first. They did the same with the forced induction simulation. I mean, this thing doesn't change much gameplay since the psi build is near inmediate, but since its all about the realism, its a small nitpick, like having a DCT car stall when you lock wheels at a high gear, or how the ABS works the same across all cars regardless of age.
