Description
2TExc is the complete toolset for designing, analysing, and tuning 2-stroke engines.
From expansion chambers to port timing, gearing and intake resonance to much more - every calculation is precise, fast, and based on proven real-world formulas.
Key Features
1. Exhaust Calculator: Full expansion-chamber geometry, cone angles, diameters, 1-stage & 3-stage layouts.
2. Cone Design: Create and build diffuser cones, reflectors, and headers with exact dimensions.
3. Reverse Exhaust Calculator: Calculate resonance RPM, volume, cone ratios, and verify existing pipes.
4. Exhaust Gas Speed Calculator: Find out the exact speed of the exhaust pulse waves via proven gas equations and varying temperatures.
5. Port Timing: Analyse exhaust, transfer, boost, and intake timings for a perfect powerband.
6. Intake Resonance: Match intake pulses with exhaust harmonics to improve cylinder filling. Extra: Calculate the optimal boost bottle and its resonances.
7. Gear Ratio Calculator: Set ideal gearing for smooth RPM transitions for a smooth powerband usage and top-speed tuning.
