hsv bimodal intake is a joke
I took my airbox out the other day to see if there was anything I could do to give it more intake/supercharger sound without changing the entire airbox setup (not ready for boost up and tune yet). The main intake area is big and looks like it would work well, the bimodal part however is tiny and I struggled to see how it would make a) more power, and b) more sound. So, I removed the bimodal flap and went for a drive. Definitely no more noise under any throttle and RPM...
Why did HSV bother? Just something "cool" to put on the spec sheet?
