Sound may not be as bad as we think!

I thought the only major difference is that wastegates recirculate the boost back into the turbo instead of releasing it? They're both used to prevent turbo and engine damage, which is why I said they did the same thing. I'm sure there are lots of other differences but,... yeah, I probably won't understand.

It's blowoff valves and bypass valves that are largely the same. Both dump air from between the compressor and the throttle on lift-off to keep the compressor from surging and damaging the assembly. A blowoff valve just dumps it, while a bypass valve routes back to the intake side of the compressor. (A bypass valve would be preferred with a mass air EFI setup because dumping metered air would cause the fuel-air mix to be temporarily rich. I'm guessing it would also be preferred with a draw-through carb because you'd rather not dump a fuel-air mixture into the engine compartment. Speed density EFI and blow-through carb don't meter air and so could just dump it with no negative consequences.)

The wastegate routes exhaust gas around the turbine. Running less exhaust gas through the turbine means less power is provided to the compressor, which limits the boost pressure to keep it from going too high (which could cause problems in any number of ways).

The old Viper still doesn't sound like a Viper. I guess I'll have to wait until GT7

They should just use the TZ3 Stradale's engine samples. It's literally a Viper with an Italian suit, yet it happens to have better samples than all of the Vipers besides the ACR.

👍 Yes. That Alfa sounds like it should.

The new Viper also has a new sample and it sounds really different from the old ones, but still like a Viper. I imagine the ACR has the same problem that it had in GT5. If that's the case, the Sports Exhaust should make it sound like a Viper.

But still, the one that hurts the most is the old GTS. They could easily just paste a sample from the other Vipers.

I wonder if their sound engine revamp will make some of these good sounding cars sound even better. The KTM X-Bow is neat, since from the cockpit you can sorta hear intake noise. I love it. Now I just hope that they fix the sounds of racing exhausts and some racing cars... like the Z4 GT3, SLS GT3, and M3/E92 GT2.

The biggest problem I have with "racing exhaust" in GT5/6 is that it seems PD has only considered titanium or carbon mufflers, instead of some nice turbo or chambered mufflers for the Inline 6's and V8's, something with a nice deep grumble

This was my former truck, all it had was a lowly 2-barrel 318 and custom 2.5" duals with Flowmaster 40 mufflers

Here's my uncle's 360 4-bbl (night time video, but sound is all that counts)

And then there's my old Mustang (may or may not be considered car porn)


PD TAKE NOTE OF HOW V8 EXHAUST SHOULD SOUND!!! EVEN WITH CRAPPY CAMERAS because I shot all of these videos except the 'stang, which I was driving (empty road behind where I used to live, don't worry)

Mercury Cougar should sound like this.



1971 Mach 1 should sound like this.



1965 Shelby Mustangs should sound like this.




Muscle cars should sound like this when you get on them.



You get the idea.

Why are you posting open header videos though...the option isn't really one in GT games.

Doesn't matter if they are open headers or not. Straight pipes (race exhaust in GT) sounds the same, though slightly quieter. And also, because "performance exhausts" like Flowmaster, Magnaflow and Thrush sound like ass. Those are about as close as all motor as you are going to get.

The issue here with PD is with certain cars, they put certain notes on cars out of context. When I mean context I mean the situation and the viewing of a car and how it sounds. When you race a car in a cockpit, you shouldn't be able to hear your engine bright and clear as a whistle, it should be muffled, covered behind your interior. Certain car sounds have this sound as if you were driving down the highway with your windows down. They should adjust it. When you are in cockpit view or hood view, it shouldn't sound like wind is blasting around you muting your engine notes.

The truth is that when Kazunori said that his engine sounds were too real, at times they were. Listening to a car under load on a dyno is very very similar to what it sounds like in the game. The problem with it is that its not the sound that everyone is used to listen to, its quite different. Also, at times it sounds like its still being run on the dyno itself. The thing is, driving and revving your car out on a track and listening to it from the outside is a sound that we could all recognize, just like someone driving a Ferrari near your street while your mowing your lawn, you can instantly tell that it sounds glorious. PD is taking an extremely digital and virtual approach to car sounds, they should tone down the processing of it and make it more raw more solid. That being said, the new collection of car sounds is quite decent and gives me some optimism.

I understand but there isn't a straight pipe setting in GT and obviously not one for open header either.

The "titanium race exhaust" is essentially a straight pipe system for the most part.

You have a catalytic converter though...

A cat doesn't change the sound all that much. Mufflers do way more. I can confirm that on my real vehicle.
