1,131 Wheel Horsepower Premier Tuning Group AMG GT-R
Showcasing our PTG-X package for the C190 AMG GT with a record breaking 1,131 HP and 974 Lb. Ft. TQ at the wheels!
In our pursuit to provide all of our AMG clients the best experience with their vehicles, we have what it takes to build you a package from just a tune to a 1,300 crank horsepower monster.
Some comparative figures:
Stock AMG GT: 450WHP
Stock AMG GT-S: 475WHP
Stock AMG GT-R: 525WHPMod list on this monstrous AMG GT-R
Induction:
PTG-X M177.1 Turbochargers
PTG C190 3” Carbon Inlets
PTG High Flow Air Filters
Crazy build! I think this breaks the record on the most hp on the GT platform!
What kind of performance figures is this setup putting down? Are you able to provide any quarter mile, 60-130 times, etc? Is this usable hp meaning can the GT platform take this much power without spinning uselessly?

It's been below freezing conditions as of late however we are planning on getting the car out to a location with better conditions to test. Our past performance figures with this setup on much less power on the stock engine was a 4.61 60-130mph. Our goal is a sub 4 second 60-130mph which we are hopeful it will do.
And yes you this might be an overall M17X power record worldwide! Thanks for the comment.
Impressive. Especially when you extrapolate that to the crankshaft values.
Assume that they drive around 2.5 bar boost pressure. Are you sure that pistons with 10.5 compression are now installed?
How much octane does this engine need?
What is your methanol injection consumption?
Has the gear set also been reinforced?
The gearbox e.g. the entire drive train is > 100% above the manufacturer's specification.
Thanks for a reply.
Kind regards.

Yes we are sure of what is in the engine.
This was on 100 Octane fuel and 2x 1,000cc methanol nozzle system we produce that gets activated via boost pressures. No need to try to make this kind of power without higher octane.
The transmission has only been opened to add our new clutch system and we have done TCU tuning.
I don’t think this group is the target for more than double the hp their cars make. If this were a Huracan R8 or 720 mclaren this is daily conversation. And I ask everyone, what makes those any better than a hand built AMG engine and trans? I can put money down that the AMG stuff is probably a lot stronger and more reliable yet there are guys making 1700-1800hp with stock motors and trans on the Huracan/R8.
Let’s carry on and make another post about wheel spacers or how the car market won’t allow me to afford the car I want.
Love it! Thank you PTG for exploring these cars, finding what works / doesn’t, pushing for more….excited to see the results and what is to come with this car.
About time someone in our “AMG GT Community” gets out there and gets us in the conversation with the other big HP build platforms out there.
What is the PTG DI M178 Fuel Pump Modification? I have a C63S and looking for ways to upgrade the fuel system. Saw your methanol kit online, looks super nice, curious what this fuel pump modification is and do you have one that would fit a W205 C63s?

I would guess that since the Huracan and 720s are in different price brackets than the GT, some of that cost might have gone to stronger transmissions *shrug*
Either way I love seeing the limits of the platform pushed Excited to glean the learnings

Gladly the opposite. The GT and 720 use the same clutch. Maybe PTG can confirm but that is the reality.
As for the transmission, the GT trans is most probably better as well. There’s reasons why the new ford gt 488 and so many others use the same exact trans.
And last I checked there’s GT’s going for 600k or just gtr’s going for 200+k.
In essence, the community like grease monkey boy in the post above said, let us know when it blows up, is just either ignorant or too lazy to simply google what a 7DCL750 transmission is, or what a Mahle forged piston is.
The only upside to a Huracan or 720 is, they have two sets of injectors per cylinder therefore not relying on the direct injection fuel system tasked to make 1,300hp. You can very easily upgrade the low pressure side on those cars and there’s enough fuel supply to handle 2,000hp. In AMG land, you’ll need billet manifolds with fuel injectors added and a way to control that. That’s a big challenge which it seems PTG combatted by adding Methanol injection.

Hi,
The 7 DCL750 is freely available from Getrag. It is one of the few transaxle transmissions that are on the free market. Most manufacturers do not build their own gearboxes.
Mercedes is the exception here. As an exception, Mercedes also used an accessory part here. Is simply cheaper than an in-house development for cars that do not have a large number of pieces.
That's why the question came:
The transmission is approved by Getrag up to 790Nm. The most powerful vehicle I know with this gearbox is the AMG GT BS with a limited 800Nm. E.g. the Ferrari 488 has 770Nm and the Ford GT II 750Nm.
According to its own information, PSG applies 974 ft / lps wheel torque to the gearbox. That should be at least (+ 10%) 1071 ft / lbs input torque. This corresponds to 1450 Nm.
This is almost 100% above the specification.
The dopson clutch may well be good. The TCU software can also be changed. But here, too, the maximum holding pressure of the clutch can be increased.
That doesn't change anything about the gear sets.
Certainly no gear will burst at 791Nm. A larger operating reserve is definitely there. A transmission should work at least 200k mls. But 100% overload.
I definitely wish that there are no problems. I just can't believe it. The future will show.
The stock pistons are also forged. And as far as I know, these are also from Mahle.
I was just surprised that the compression was increased. AMG drives in the series max. 1.2 bar boost pressure with 10.5 compression.
GTR / BS drive 1.35 to 1.5 bar boost pressure. Here the compression has been reduced to 8.6. Makes sense too.
PTG has an estimated boost pressure of around 2.5 bar. With now 10.5 compression. You can quickly reach the knock limit. LOL
If it can prevent the methanol injection. Good. However, the consumption of methanol is likely to be extremely high.
This projekt is certainly about the maximum possible. The data is impressive. Respect.
Suitability for everyday use is certainly not at the front of the specification sheet. LOL
Best regards
Stenzel

The GTR has 9.5:1 compression and the GT GT-S has 10.5:1.
I’m not going to speak on PTG behalf but it seems they understand what knock is. And knock is a function of cylinder pressure and octane. You’d see knock on the graph.
But anyway we’re speaking the same language. This is how the platform starts to make big power and manufacturers like PTG among others start building what is needed next.
