● Just crank up the volume and enjoy the exhaust notes of this 2024 Porsche 911 992 GT3 RS fitted with Dundon Motorsports Inconel megaphone crackpipe exhaust system and an ecu tune by BiesseRacing.
0:00 start up, revs
1:17 dyno pulls (pure sound)

I can never get enough of the 992 GT3, or any of its other variations.
Crazy how the engine doesn't even come alive until like 6000rpm!
AFR is so perfect it doesn’t even backfire.
Love Dundon Motorsports, absolutely phenomenal group with passion. Outside of their, exhaust packages, their aero kits are really amazing as well.
Pinnacle sports car
I added this German song to my playlist haha
That my friends is how you do a proper dyno video!!!!!
Great observation...and I absolutely agree!
These are every enthusiast’s dream for a reason ❤
La Macchina per eccellenza GT3 RS 😍👍💪
What happen between 2500-3500 rpm?
why sometimes do they go in neutral after a run?
I'm also curious about that
I imagine it's beacuse of the magnetic brakes on the dyno, so, it can stop de car just letting it rolling.
If you want to mesure the power you press the clutch or go to neutral (dct) after you hit the rev limiter
I think it's to measure the dissipated power from the drivetrain to be able to calculate the HP
Depends on a couple of things, first the dyno might measure coast down, so car in neutral and the dyno measures loses, other reason would be when you see cars do a pull on the dyno then put in neutral and rev that would be to keep oil pressure up for cooling the systems
I think I could could just listen to this all day and shut the rest of the world out completely 😂
Symphonyie !!
The upshifts this car does is crazy
Já pensou se a Porsche consegue fazer a Mark 2 chegar nos 10.000 rpm 🤌
😍😍
This is a insane car- and i know what m talking about
With a spoiler this big I could probably fly to the moon 😅
Sick. Sick.
BTW 991.2 rsr = wooooooooooooow
Berry Good 🛞😀🚘😎 cool 😊
Wow, the sound keep getting higher after 8,500 RPM. Usually in some other aftermarket exhaust it does not. Does the ECU need to be remap? Or you have OBD/ canceller.
🎶😍👌
I want to be part of you guys ! Hire me as apprentice ❤ (seriously)
📣📣📣
Race Cats or Stock?
Can the car pass euro inspection with the gas particulate filters removed?
No. But dont think owners will care.
3:03 ~ 🤔 side brake...?!
I thought the gt3rs was rear wheel drive?
It is, but some cars need the front to be spinning otherwise the ECU gets angry
Ahh makes sense!
These can be out into dyno mode, but rhe superflow dyno they have is permanently running all rollers through a large drive shaft

Around 3k rpm the car is suffering from “megaphonitis”, a common problem with this kind of exhaust. There is a reason motorcycles went away from this style, but I guess it’s marketable for the company given the lack of consumer knowledge about exhaust harmonics.
I used to make music when I was younger, and it's made me come to enjoy the sounds of many things.
If it's okay, can you tell me how it's an issue and how it works? I don't mind if it's long, I'll read it all anyways.
@@recon1673 every exhaust has positive and negative pressure pulses flowing back in forth in the pipe. Using length and diameter of the pipe we can time the negative wave to arrive during the period when the exhaust valve is closing and intake opening (this is called the overlap period). If we get the negative pressure wave to arrive during the overlap period, the negative pulse will pull the intake charge into the cylinder at a higher pressure (up to 4-5 psi or more). This is highly beneficial for torque/volumetric efficiency because you are filling with more air than simply the negative pressure area of the piston moving down.
What is important to note is that this negative wave occurs over a very narrow range of rpm, but is very effective in that range. The problem with this wave tuning is that usually there is a range where instead of a negative wave arriving during overlap, it’s a positive wave. The positive wave actually pushes exhaust back into the cylinder and is very detrimental to cylinder filling and torque.
On to the megaphones. The megaphone shape can accentuate the wave tuning effects that I described above, and the dip that I described caused by the accentuated positive pressure wave may be because of the megaphone (the term that was coined for this is megaphonitis). This kind of exhaust has been touted as being better mostly from a marketing standpoint, in reality the most important thing overall is not peak torque/hp but a smooth wide curve.
If you want to learn more check out the cycle world articles by Kevin Cameron where he talks about wave tuning and megaphonitis. Hope this helps.
As everyone listens to it on phones ...
Esplêndido exaust
Sounds pretty anemic to me.
Wow so bad torque. See the numbers at 4:18
The engine is designed for high rpm power. That sacrifices torque
car is designed to sacrifice low end torque for high end torque and power, unsuitable for daily driving but perfect for track use since you'll never be under 5k rpm on this car
Yes but other cars wich can also rev to almost 9000rpm (ferrari 458, audi r8…) has very good low end torque
Even the GT3 non RS has better low toeque
@@S25117those have bigger engines.
@@S25117those both have bigger displacement and are tuned for a more balanced power delivery, they just also happen to be able to rev that high
The way this engine with it's sounds helps my psychotherapy, nobody does🫠
