Iwant a thorttle body but I heard it can be bad for your car. Looking into a 75mm. Also I heard there a way to make it sound supercharge when its not, is this the t/b or something else? I know it sounds stupid and all, just thought I would ask!

 

nothing is going to make it sound like a supercharger except a suerpcharger. a 75mm wont hurt you but its not going to help much either unless your cammed
