i saw an rx-7 drive by me the other day and it had a diffrent sounding bov. i liked it alot but never herd one like it. it makes like 3 or 4 sounds when it blows off one time. it not like a normal pssssh sound that all the others have, it wasnt as loud but i like the consecutive sound it had. wondering if anyone knows what kind of bov it is or one like it.

 

Probably the HKS Sequential.

 

3 or 4 noises that's weird???

 

Were the consecutive sounds varying in tone? It could be compressor surge like in the GT1 Porsche but for a 7 to have it, its BOV would have to either be nonexistant or failing. For you to hear it from a distance, it would have to be running pretty strong boost levels too.

 

so i take it that i cant have that sound? the sounds did vary but like from strong to weak to none . i dont know about boost didnt seem like a single, but could hear it pretty well right next to the car. i was gonna ask the guy but he thought i was racing him and he jetted.
