Porsche produces all of their 911 Turbo engine blocks out of aluminum. The 997.2 generation switched to aluminum from the classic GT1 (Mezger) iron block and it is aluminum used ever since. That makes the block lighter but as boost and cylinder pressure increase with Porsche upping the power block integrity eventually becomes an issue. We see stock internal Porsche 991 Turbo 3.8 blocks holding up to lots of power but Porsche durability testing and aftermarket testing are different things. Not to mention, Porsche knows there is a segment that buys the 911 Turbo to modify it and to keep up with the big boys the Turbo will need to be able to take abuse. Porsche is increasing 992 Turbo S horsepower to ~650 stock and that figure is probably underrated. They are doing this with a revised intake, manifolds, intercooler, and larger VTG turbochargers. The bigger turbos will push more air. The 991.1 Turbo and Turbo S shared the same VTG's and struggled to top the 997.2 in bolt on performance. The 997.2 Turbo S did run 9's with bolt ons. The 992 Turbo S will be the strongest bolt on tuned Porsche Turbo yet on the factory turbochargers. We might see a high 9.X in the 1/4 mile out of it stock meaning it is going to go deep into the 9's tuned. With the new 8-speed PDK (it will share the Carrera S ratios but with a different final drive) the car is going to be a monster out of the hole. The PDK is more compact but heavier than the 7-speed it replaces so it sounds like Porsche made sure it is beefed up for 992 Turbo duty. The front differential is also watercooled and strengthened: All signs point to a driveline reinforced to take a serious beating and Porsche would not add iron liners at additional cost just for fun. The 992 Turbo should be epic.

93 octane pump gas results are important as not only will the majority of MKV Supras see pump fuel the majority of tuned examples will not go beyond what the factory turbo offers. The MHD Stage 2 paired with a catless downpipe is the perfect daily driven recipe. There is plenty of punch picked up while keeping things reliable and not pushing the factory turbo too far. Just over 100 horsepower at wheels was picked up over stock: Notice the torque curve is not some crazy stump puller for peak figures but smooth and linear mirroring the factory curve just with far more area under that curve. The top end holds nicely toward redline allowing for a nice overall area increase in power on the top end from 4500 rpm on. Solid, reliable, and repeatable results.

You may remember this LMR1000 tuned C7 Corvette ZR1 from a video last month where it absolutely destroys a tuned Lamborghini Aventador SVJ. Well, that same ZR1 now picks on a stronger opponent in the form of a McLaren 720S. This 720S must be stock as how else do you explain the way it gets pulled? These are not even runs. Pulling away from a 720S with ease like this truly points to a supremely fast car. Now let's see some runs against modified 720's to make this more interesting.

You are going to see M256 tuning pick up as more Mercedes models roll out with the motor. This is the new Mercedes modular engine architecture which is very similar to what BMW, Porsche, and basically all German OEM's are doing to cut cost by sharing engine parts among various displacements. The W213 E53 AMG sedan and the C238 E53 AMG coupe variant both have this motor. Output is 429 horsepower stock and Weistec can raise this by 43 horsepower and 90 lb-ft of torque. Add in the catless downpipe and output goes up by 58 horsepower and 105 lb-ft of torque. No dynographs yet.

We all knew the Predator 5.2 V8 was going to be strong but damn did Ford deliver and then some! The 2020 GT500 is just getting into owner hands and fortunately we have some Dynojet figures to go on in both SAE and STD correction factors. Let's start with STD correction topping 700 to the tires: SAE correction produces a more realistic 684 rear wheel horsepower: Considering the blower capability you can sneeze on this motor and make 800+ rwhp. It is only a couple horses shy of a Demon on pump fuel: BoostAddict expected output between a Hellcat and a Demon but not for Ford to basically deliver Demon power out of the box. Well, they did and the GT500 is even underrated at its 776 horse crank rating. It is going to take 700 horsepower to the wheels to begin to play with the big boys in 2020. This may be the peak of the golden age of horsepower right here.
