Hi guys, when watching videos of ep3 with JR supercharger i normally hear the nice whining noise of a supercharger but lately my friend fitted one on his car and to be honest you can hardly hear it. his car is fitted with DC header and catback. What makes the supercharger make that lovely sound. my friends car is on the 6/7psi pulley btw.

thanks

 

a intake really helps with the whining noise. but it should already make one without it.

 

yea that is weird. i'm pretty sure you should here it when he stomps on the gas but i dont think it makes that whistle sound all day. or maybe he should push 9 psi

 

hehe intake does help a lot! does he have k pro and a fine tune? if not that could be the reason!
