Bov (blow off valve) sounds

Question

Hello, i need some help to make a bov sound effect for turbocharged cars like turbo spool or flutter

Any ideas on how to make that ?

If you can help me even with the basics only i would be grateful, thanks

Vehicles expose all the information you may need to emulate it. For example, I'd monitor the throttle and the engine rpms. Measure the time the throttle is pressed more than 50% and rpms are beyond some threshold (i.e. 5000). If both conditions are met continuously for a certain time, then releasing the throttle plays the BOV sound. I had done something similar in Edy's Vehicle Physics, by just monitoring throttle and rpm.

Check out the VPVehicleToolkit component for learning how to read the information from the vehicle:
