PISTONS UPGRADE VAG 1.9TDI - MF PERFORMANCE
PISTONS UPGRADE VAG 1.9TDI - MF PERFORMANCE
MF Performance UPGRADE PISTONS – VAG 1.9 TDI PD
The smart solution to improve the reliability of your tuned 1.9 TDI our Upgraded Pistons are original pistons optimized (CNC machining), designed for Reduce the cylinder pressure peak, prevent your valves from hitting your pistons And protect your engine .
Why upgrade to PISTONS UPGRADE?
- A stock TDI works at ~110 bar cylinder pressure.
- When prepared, one often exceeds 220 bar ➜ risk of cylinder head detachment and breakage.
- Use a camshaft with a high lift
- Use larger diameter valves
Our answer: lower the volumetric ratio of 19:1 (origin) to 18:1 in increasing the bowl volume, modifying the diameter and depth of the valve recesses. Result : reliability And safety margin .
What you earn
- ✅ Less mechanical stress on the cylinder head and the lower engine block under high pressure.
- ✅ Reliability on the prepared configurations (track, drag, etc).
- ✅ Reproducible solution and clean vs. random DIY projects.
Technical specifications
- Kind : original pistons machined/optimized CNC
- Target volumetric ratio: 18:1 (originally 19:1)
- Bowl Volume : 22.3cc (43 mm) (optimized geometry)
- Valve imprint modification Valves can accommodate up to 39mm, with a lift of +10.5mm
- Compatibility: blocks VAG 1.9 TDI PD
We explain everything in a video
We explain why this volumetric ratio, the impact on the cylinder pressure etc..... and how exploit UPGRADE pistons.
FAQ
Should the mapping be redone?
Yes, it's recommended to optimize starting, fumes and performance.
Impact on cold starting?
With a properly functioning preheating system and careful mapping, the behavior remains stable for road use.
It's plugged in && play?
The pistons are made for your 1.9 TDI Plan for a clean assembly (metrological checks, piston ring end gap, new gaskets) and a dedicated map.
