Comparison of ANC/ASE on and off

I drive the manual, and to be honest I hear the engine better, before it sounded muted now I can hear it enough for me to know when to upshift if that makes sense.

Do you notice a whooshing noise, maybe intakes or turbos, more?

Nope. Nothing, just the exhaust and transmission, I haven’t upgraded the intakes or turbo or exhaust yet, but the stock sounds is louder.

it’s funny because in gran turismo 7, the turbo blow out is loud and before I test drove the real car I was expecting to hear it.
Low and behold I discovered this car has ANC/ASE

It’s funny because my favorite racing game of all time Tokyo Xtreme Racer finally released their full game on steam yesterday and grinded a few hours to unlock the rz34 and in the game, you hear the twin turbos

btw that game has some sick Impul and vary kits

no - still quiet as a mouse with stock intake.

i like the way you are thinking - they should do ASE for boost intake & blow off

There isn’t a ‘blow off valve’ unless you add them. As I understand it, there are solenoid diverters that vent the turbos back into the engine intake. Weird for a turbo setup imho.

GT7 accurately simulates the new Z. It's not 100% but very close especially the handling. The turbo sounds are just there for effect for any turbo car though. In real life even though I don't hear the blowoff sound hearing the intakes is satisfying.

I was curious about this also. An amateur car buddy told me it's probably an intentional design choice to keep pressure up in the system and/or so pressure drops slower than if it's exhausted quickly to atmosphere. So as you let off gas entering a turn the system has more turbo power ready for you on the way out. Dunno if this is true, anyone know?

All modern turbo cars use recirculation valves instead of blow off valves afaik, it mainly has to do with using a MAF and not "blowing off" air you've already measured and accounted for. You can run our cars and other recirculation bypass valve systems vent to air with an aftermarket kit, but it might throw a engine rich/misfire code and cause popping in the exhaust/ possibly damage the cats long term.

I'm not sure if it also helps keep the turbos spooled, in theory maybe slightly because you're re-introducing air that has already had work done on it back into the turbo inlet which may lower the pressure drop after the air filter, but also as a downside it's going to be hot air now.

The weird thing about the Z is that the valves are electronic, but i think this is becoming more and more common as well.
