"Twin Turbo" Porsche 911 GT3 RS has 800 horsepower, the sound is different

I made a Porsche 911 TT3 RS

If you think, "I just want to ride a Porsche 911 equipped with a twin turbo, which is extremely fast!", I think that the Porsche 911 GT2 RS should be considered for purchase.

The Porsche 911 GT2 RS is a 3.8-liter horizontally opposed 6-cylinder twin-turbo engine that produces 700 horsepower.

A fast Porsche that can run not only on the circuit but also on public roads.

And the Porsche 911 GT3 RS is also amazing, but this is a naturally aspirated (NA) 4-liter horizontally opposed 6-cylinder engine model.

If you are considering the Porsche 911 GT2 RS but say "But the NA car is good!", "I want a fast Porsche!", I dare to choose this Porsche 911 GT3 RS instead of the GT2 RS. I think there are times.

No, I don't think that in reality, I don't think that I will choose GT2 or GT3 for that reason, but in this talk, that may be the case ^^

Well, that's why this story.

Edmond Mondi, who is also a You Tuber, longed for the awesomeness of GT2 while maintaining the soul-stirring sound of GT3.

In order to fulfill that wish, Porsche 911 GT3 RS equipped with twin turbo and with tremendous aero parts ... No, according to his naming, "Porsche 911 TT3 RS" has been made.

This is what I bought. ↓

This GT3 RS (TT3 RS), the engine is still a 4-liter horizontally opposed 6-cylinder engine mounted on the rear, but a 76 mm turbocharger was installed there and the performance of the car was raised to 800 horsepower. ..

He plans to increase the horsepower to 950 horsepower in the future, and he thinks he can bring it up to 1,200 horsepower.

I can only say that the rear diffuser is amazing.

This rear wing is so big that I thought it was a bug in the video ↓

Somehow amazing aero parts are attached to the side sill and front, and according to Mondi, these can create a downforce of about 1,600 km.

This time, there was a video of You Tuber's Shmee150 going to get on this Porsche TT3 RS, so I saw this car actually running on a public road & listened to the sound. It was.

Certainly a great sound! !!

The sound of the explosion when entering a small tunnel (?) On the way is too loud (around 8:18 in the video below).

Here is the video ↓ Just running on a public road is a great sound.

Is the sound of the Porsche 911 GT3 RS retrofitted with a turbo different from that of the Porsche 911 GT2 RS?

… And as an amateur, I was very wondering here.

Yes, it is about "I want the performance of GT2 RS while retaining the sound of GT3 RS of NA". I can understand what you are saying.

But when it comes to "To do so, I attached a twin turbocharger to the GT3 RS."

Hmm? ??

That is, "It's like the twin turbo GT2 RS from the beginning, so why not use the GT2 RS from the beginning?"

But actually:

• Originally a twin turbo GT2 RS
• Twin turbo retrofitted to NA's GT3 RS

It seems that the sound is completely different between the two units.

The difference in sound is the difference in the compression ratio of the engine

What makes the difference is that "there is a difference in the compression ratio of the engine".

• The compression ratio of GT2 RS is "9.0: 1"
• The compression ratio of GT3 RS is "13.3: 1"

This difference in compression ratio seems to be one of the reasons for making a difference in sound, and since the compression ratio of this Porsche TT3 RS engine is still 13.3: 1, it is equipped with a twin turbo, so GT2 RS It seems that the sound is completely different from that.

It seems that the turbo car has a lower compression ratio. Haha.

Well, then, if you compare the compression ratio of the engine in the turbo car and the NA car with other Porsche 911, is it really different? When I wondered ...

• The compression ratio of the new Porsche 992 Carrera is "10.2: 1"
• The compression ratio of the Porsche 911 GT3 (991.2) is "13.3: 1"

Wow, that's true. Turbo cars have a lower compression ratio. (I wonder if this level of understanding is okay ... My knowledge level is lower than any compression ratio ^^)

* Of course, in addition to this compression ratio, there seem to be various differences that affect the cam profile, valve train, exhaust piping setup, etc.

I don't know anything about the mechanical things, so if I try to understand it more deeply, I'm likely to fall asleep, so anyway, "Isn't the sound of the twin turbo GT2 RS and the turbo retrofit GT3 RS the same from the beginning? I just knew that the answer was "No", so it's OK! ← Appropriate as usual ^^

No, even so, various people are enjoying various Porsche. It's amazing!

Finally, this is like the promotion video of this Porsche 911 TT3 RS ^ ^ ↓
