Description
Percheron Land Speed is a land speed build for the stock Cherrier Percheron that keeps the 12.8 L inline six diesel. It features a ready-made "Land Speed 4x2" configuration and is designed to reach 400+ km/h.
No new meshes are used; every part is a stock Percheron part with different physics values, ensuring it loads instantly, works with any Percheron skin, and does not overwrite stock files.

Features
- Engine: 5500 rpm long block, compound turbo mapped to 170 psi, ECU with adjustable rev limit (2200 to 5400) and wastegate (39 to 200 psi), no speed limiter. 4633 hp and 6219 Nm at default 120 psi, and about 5640 hp at 150.
- Stage 1 Engine Package: 4000 rpm long block, single big turbo, 3600 rpm ECU for 200 km/h trucks.
- Driveline: Heavy flywheel and 2.40:1 rear final drive.
- Cooling: Double-core radiator, 350 L ice-water tank, and large oil cooler.
- Aero: Low-drag L cab, nose cone, splitter, front and rear wheel fairings, sealed fascia, and grille block-off (42% less frontal drag than stock panels).

Driving Notes
- 12-speed manual with splitter. Hold 6th low to about 390 km/h, then split high.
- Boost only builds under load: one or two bar at a standstill, seven or eight at full throttle in gear.
- Expect wheelspin through the first four gears. Short-shift or roll into the throttle.
- Coolant should sit around 90 to 100 °C at speed. If it climbs past 120 °C, the cooling part is not fitted.

Known Limits
The low-drag cab exists for the L cab only; S and XL cabs work with the rest of the kit at stock drag. Built and tested on 0.40.4.
