How does a rotary engine sound like?
As a first time rotary car owner (89 FC3 Vert), I had no idea what a rotary sounds like. I don't even know if my car's making the right sound either. When I rev it up, engine makes a whining noise at the end, it's like a propeller whining sound. Is this normal???

The OEM exhaust sounds a bit "tinny/quiet to me." I like the HKS exhaust personally as it's nice & throaty and has a distinctive rotary high RPM sound that's NOT buzzy, tinny, or "hole in exhaust" sound like most cheap 4 cylinder exhaust systems. It sounds really really good and is a thrill to hear/experience.
The Racing Beat system has a nice note as well, but is a bit quieter.
Besides exhaust you'll hear the air-pump (emissions) venting above 4500RPMS I think (that wooshing sound) and you'll notice the tone change when the VDI (variable duct intake) system opens up ~3600RPMS I think and again at 6500RPMS. (can't remember why the sound changes at that RPM offhand.

Once I left my Maz idling outside of a bank so I could draw money from an ATM, and this woman came outside the bank and said "Where's that chopper I can hear?" I said, "that Aint no chopper, It's my turbo RX7!" She just went "oh!", and walked back inside!
I love the sound of the car starting, when It sits on about 1500rpm during warmup.
I have a home-made, straight through, twin 3" system from the downpipe, with two humungous "Rota-flo" (Aussie icon) Stainless packed mufflers! ($400 each AUD). My only problem now is that the boost cut takes all my fun away when I floor it!

VDI opens around 6500RPM

Friends told me my '84 GSL sounded like a Hoover vacuum cleaner (stock)
best description I've heard is a weedwhacker on crack.
I dunno, when I've been behind them they have a strong "metallic" sound, if that means anything.
