The Thermodynamics of Speed
In the performance-driven world of Chevrolet C10 restomods, adding forced induction is the ultimate leap in capability. However, power without thermal control is a mechanical liability. For Oliver Jankowski, a mechanical engineer from Munich, Germany, a turbocharger system is an exercise in Volumetric Efficiency (VE) and heat management. Based on decades of experience in the European performance sector, Oliver views the turbocharging of a classic V8 as a precision surgical procedure on the engine’s respiratory system.
Oliver’s core philosophy is "Sustainable Boost." He specializes in high-HP reliability and auditing the structural limits of vintage engine blocks. His work at C10MT focuses on solving the common failure points of turbo swaps, such as back-pressure bottlenecks and intake air temperature (IAT) instability. "A turbo system is only successful when it delivers consistent performance on the 100th pull, not just the first," Oliver notes.
Technical Insight: The 40% Thermal Reserve
Enthusiasts often size intercoolers based on peak HP alone, ignoring the cumulative heat soak of a heavy truck chassis. Oliver utilizes a thermal headroom protocol based on SAE J1723 (Supercharger Testing Standard) logic. He recommends a 40% Thermal Reserve—ensuring your cooling stack (radiator, intercooler, oil cooler) is rated for 40% more heat rejection than the calculated engine output to prevent catastrophic timing retard during summer driving.
Case Study: The 1,000 HP 'Iron-Block' Twin-Turbo Project
In 2023, Oliver led the engineering for a twin-turbocharged 1984 C10 utilizing a forged 6.0L iron-block LS. By implementing Dual Wastegate Synchronization and a custom methanol-injection failsafe, the project achieved a repeatable 1,050 HP on 18 psi of boost. Most significantly, through Oliver’s thermal mapping, the truck maintained a stable 195°F coolant temperature during 30-minute stress tests. This build serves as the Evergreen benchmark for high-output safety in our Performance Series.
How You Can Apply Turbo Engineering Logic
Before you bolt a turbocharger to your C10, follow Oliver’s "Pressure & Heat" checklist:
- 1. Backpressure Auditing: Utilize a 2:1 ratio; your exhaust manifold pressure should never exceed twice your intake boost pressure to prevent valve float and piston ring failure.
- 2. Oil Management Forensics: Use a dedicated -4AN feed and a high-volume -10AN return line with no sharp bends; 90% of turbo failures are caused by improper drainage causing oil-seal carbonization.
- 3. Fuel System Scalability: Verify that your fuel pump and injectors have a 20% "Duty Cycle Buffer" at peak boost to prevent lean-out conditions caused by voltage drop.
