CASE STUDIES
Real-world engine builds validated with dyno data. See how PISTON helps builders make smarter decisions.
The Challenge
Customer wanted to maximize naturally aspirated power from their LS3 Corvette while maintaining streetability and reliability. Budget: $8,000. Goal: 500+ HP at wheels.
Simulation Approach
Used PISTON to simulate three progressive builds, comparing camshaft, intake, header, and head combinations. Evaluated power gains, cost per horsepower, and drivability trade-offs before purchasing parts.
Results
BEFORE
430 HP @ 6000 RPM (Stock)
AFTER
512 HP @ 6400 RPM (Stage 2)
IMPROVEMENT
+82 HP (+19%) naturally aspirated
Dyno Validation
Simulated
512 HP @ 6400 RPM
Actual Dyno
507 HP @ 6400 RPM (dyno)
Error
0.98% error (well within <7% target)
Cost Analysis
TOTAL INVESTMENT
$7,850 (under budget)
COST PER HP
$95.73 per HP gained
Parts List
- COMP Cams Stage 1 LS3 Camshaft (220°/228° @ .050", .624" lift)
- Kooks 1.875" Long Tube Headers
- FAST LSXR Intake Manifold (102mm throttle body)
- Custom dyno tune (not simulated, added ~8 HP)
Key Lessons & Insights
- 1.Stage 1 (cam + headers) gave best bang-for-buck: 65 HP for $3,200
- 2.Stage 2 intake swap added only 17 HP but improved mid-range torque significantly
- 3.Simulation prevented over-camming: Initial 240° cam showed worse street performance
- 4.Port matching intake manifold worth the extra cost for better flow transition
- 5.SAE correction factor critical: Raw dyno vs. simulated showed 3% variance until corrected
