The ks_porsche_911_gt3_cup_2017 in Assetto Corsa is a masterclass in pure, high-revving precision. Mastering its RPM range is the difference between fighting the car and finding that perfect flow. The Heart of the Beast: 4.0L Boxer Specs
Unlike the road-going GT3 which might touch a 9,000 RPM redline, the 2017 Cup car is built for sustained competition endurance. Max Power: Approximately 485 BHP delivered at 7,500 RPM.
Engine Type: A high-revving 4.0L flat-six naturally aspirated engine.
Transmission: A sequential six-speed paddle-shift transmission designed for rapid-fire changes. Mastering the Shift Points
Finding the "sweet spot" is critical for maintaining momentum. While some GT3 cars benefit from shifting right at the redline, the power curve of the 2017 Cup car dictates a more nuanced approach.
Optimal Shift Range: Aim to shift when the dash lights indicate peak power, typically around 7,500 to 8,000 RPM, rather than bouncing off the limiter. assetto corsa ks-porsche-911-gt3-cup-2017-rpm
Gear Management: In technical sections like Segment 11 at Spa, you'll often need to downshift to 3rd gear to maintain a minimum speed of around 117 km/h for an optimal exit.
Rev Matching: While the modern sequential box is forgiving, staying within the optimal power band ensures you don't bog down on corner exit. Performance Benchmarks
If you're looking to gauge your RPM management and overall pace, here are current targets from sites like Track Titan:
The Porsche 911 GT3 Cup (2017) , internally designated as ks_porsche_911_gt3_cup_2017 in Assetto Corsa
, represents one of the most demanding and rewarding driving experiences in the simulation. This car was introduced as part of the Porsche Pack III DLC. Technical Heart: The High-Revving Flat-Six Problem: The car spins at 7,500 RPM in 2nd gear
The soul of the 2017 GT3 Cup is its 4.0-liter naturally aspirated flat-six engine.
Power Output: It produces approximately 485 hp (357 kW) at peak performance.
RPM Dynamics: The engine is designed for high-revving performance, with a maximum engine speed of 8,500 RPM. In related high-performance models like the GT3 RS, this limit extends even further to 9,000 RPM.
Transmission: Power is delivered through a 6-speed sequential dog-type gearbox. Performance Characteristics
In the world of sim racing, this car is legendary for its "pure" but punishing handling. Rule 1: Never fall below 5
Most drivers keep the final drive at default (approx 3.70). For Spa or Monza, lengthen it (3.60). For short tracks like Brands Hatch, shorten it (3.90).
If your revs drop below 5,500 in second or third gear, you have lost the corner. The engine will require 1.5 seconds to climb back into the power band. In sim racing, that is a lifetime.
Porsche race engineers do not shift at the exact limiter. They shift just before it. Why? Because the engine electronics cut fuel slightly at 9,000 RPM. In Assetto Corsa, that cut feels like a micro-stutter.
Wait, tires affect revs? Indirectly, yes. If your tire pressures are wrong (below 25 psi hot), you have massive rolling resistance. The engine must work harder to spin the tires, meaning you lose acceleration RPM. Your engine will feel "lazy."
Target Hot Pressures: 26 psi front, 24.5 psi rear. This minimizes drag and allows the engine to rev freely.
| Corner | Entry Gear | Target Entry RPM | Apex RPM | Exit Strategy | | :--- | :--- | :--- | :--- | :--- | | La Source (T1) | 2nd | 7,000 | 6,000 | Short shift to 3rd at apex | | Eau Rouge / Radillion | 4th | 7,500 | 5,800 (Flat out) | Trust aero; do not lift | | Les Combes | 3rd | 7,200 | 6,500 | Smooth throttle roll-on | | Bruxelles | 2nd | 6,800 | 5,800 | Early throttle, short shift | | Blanchimont | 5th | 7,800 | 7,000 | Flat out | | Bus Stop Chicane | 2nd | 6,500 | 5,500 | Danger zone – gentle throttle |
As you can see, the chicane (Bus Stop) forces the engine to hang at 5,500 RPM. This is the hardest corner for the Cup car because the engine is asleep when you need power, then wakes up violently as you exit over the kerbs.
