I would love to hear the blow off valve sound from the subaru sti. In the real thing it is clearly audible. In any turbo car I want to actually hear that sound as it adds alot more to the car.

This is the Blow Off Valve sound. Listen to when he shifts.

The sound of air being released.
 
Demonstrate from a youtube video so me and other people will have a better idea what is that BLOW OFF valve thing :)
 
The supercharge whine is also missing, especially from the Mini Cooper S.
 
You mean a dump valve? or waste gate? I don't think every car has to have it, although it would be good if it was in the full game so you could be able to purchase it.
Here's a link to the great sound of a supercharged Renault Clio V6.

I think this is originoo187 video. I don't want to breach any rules :D

The thing he's after is the sound the wastegate makes when it releases excessive turbo pressure.

 
every turbo car has a blow-off valve. but stock ones are recirculated and do not remove excess air to the atmosphere and not as pronounced as the HKS one you mention above.
 
There are few auxiliary sounds missing in the game. For one, I was hoping the Tuned cars would have straight-cut gearboxes and have Gearbox whine (I love that).

Example:



How a V8 race car should sound :D

They've also missed out backfires, brake-squeel, Supercharger whine and a few others that make the experience so much more.
 
Well that is a built race car and I can see why the game does not sound like that due to the fact that the cars in GT5P are stock. But some stock cars do make diffrent sounds taht need to be put in.

Stock cars don't have blow off valves, they have diverter valves. The difference being blow off valves release the air into the atmosphere, which in reality would be hell on the ecu for the car. The maf registers XXX amount of air being taken in, then the blow off releases some air and the suddenly you have fuel for XXX air, but only XX air actually there.

...and the sound doesn't happen when he shifts. It happens when he abruptly takes his foot off the gas for the shift and the throttle body slams shut...yes there's a difference. And all turbo cars have one, it's a necessary part of a turbo system. You can't have the turbo trying to cram in 18psi through a gate, then suddenly the gate slams shut and the pressure has nowhere to go.

it's not missing, the new mini's are turbo.
 
Wastegates and blow-off valves are not the same thing and do not make the same noise. I'm fairly certain that the OP was wanting to hear the BOV, not the wastegate.

Yes it is missing. The 06 is still a supercharged R53 model, the new 07+ R56 model that is turbo charged isn't in the game.

The Mini in the game is the R53 Mini Cooper S which was Supercharged. I should know, I own that generation Mini Cooper Works :D
 
Well, i just made the mini assumption, I haven't even been the 'mini' section in the dealership yet. I figured they'd be running the new minis, but I guess not.

You have no idea how the subaru sti sounds do you. The stock STi has a blow off valve and it is very audible.
 
Some (although rarely) turbo cars don't have any bov as stock. My previous S13 Nissan didn't have one in stock form, I was quite surprised to be honest. Surely all a bit more powerful ones have either a dump or a by-pass valve when stock.

And to the question at hand. Yes, GT5 needs more audible turbo spool/bov sounds.

Thank you at least you know as well as I do that this game needs more spool and turbo sounds.

and i'll quote the important part for you:
The higher-flow intake not only adds aural excitement (turbo sounds and swish from the stock diverter valve are less muted) but also boosts power by a factory-claimed 45 bhp and 24 lb.-ft. of torque.

Yes, I know what an STI sounds like.
 
Most standard blowoff vlaves are less audible do to they are plumbed back as stated and they run air boxes which cuts a lot of induction noises out. The blow off valve works when there is a difference in air pressure from one side of the throttle body to the other. Ie you shut the throttle and the inlet manifold has vacuum but the other side still has say 5psi due to the turbo still spinning. The vavle opens and the air is vented. Most aftermarket valves open to the atmosphere hense why they are louder.

CA18 and SR20 S13's both have blow off valves from the factory so if it wasnt on there it was removed.

A wastegate is on the exhaust side and essentially opens a hole in the exhaust to reduce the exhaust pressure spinning the turbo. The only purpose of this is to control the boost level and the only time it opens is once the turbo has reached its set maximum boost level. You cant hear a wastegate, you may hear however when somebody has a "screamer pipe" with say an external wastegate (or some goons do it with internal gates) and have the exhaust pipe dumping straight to the atmosphere rather than back into the exhaust.. There it is an un-muffled sound that hasnt entered the turbo and is very loud.
 
Blow off valves are not commonly equipped as stock. People add them as aftermarket and sacrifice air fuel ratio efficiency as a result. Most stock turbo cars come with "bypass valves", which make much less noise.
 
It is very hard to hear the BY PASS valve and turbo in a stock 07 STi, I had to take the resonator box out of the right fender to be able to hear the by pass valve and turbo in mine.
 
The turbo noises in this game SUCK. The blitz skyline sounds borderline NA! The thing should have an ear piercing blow-off valve because the things probably running 25psi or something. Also I NEED to hear some open-wastegates and straight gears in GT5. Thats the only thing I really want added onto the game.
 
the VTEC in the honda engines should be heard as well. i think it's very important if they're gonna call this as a driving simulator.

That's a negative. All finnish CA18DET RS13's that I have seen/worked on have not had one when stock. Been the same story in finnish official imported Nissans and cars imported second hand from Germany, neither have had one. AFAIK all SR20's have a re-circulating valve though, S13 and S14. This is also why the CA18 ECU doesn't go bonkers when you install an aftermarket BOV to it, while SR20 ECU does get confused from the faulty readings by the MAF.

As has been pointed out, your reference point is an aftermarket HKS blow-off valve.

Having been intimate with an Impreza RB5 PPP and an Impreza WR1, they sound nothing like that, and I've never heard that sound from any standard production road car ever.

That i guess i can live with as I am always in the VTEC zone :)


Actually, cars like DC5 stock has very minor sound changes during vtec crossover unless you have open air intake.
