Forged piston set 83.75mm 1.8L 8V VW 1.8 8V
For VW 827 1.8 8V engines Nominal bore diameter: 83.75mm (increase engine displacement to 1903cc) Recommended bore to piston to bore clearance: 0.08mm (For nitrous or extreme applications, consult your builder) Piston ring grooves: 1.5 mm / 1.5 mm / 2.0mm Compression height: 32.40mm. Dish volume: 17.3cc Compression ratio: 8.7:1 Pin offset: 1.10mm. Material: Forged aluminum 4032 T6. Average piston weight (unit, without pin): 326g (11.49 oz). Rated for 1000hp. Innovative high performance piston skirt design that provides: 1. Smaller piston to bore clearance 2. Less noise 3. Better ring seal 4. Higher power 5. Durability Features: Anti detonation grooves: protect the top ring by disrupting detonation waves and reduce piston-cylinder contact in high temperatures and engine RPM conditions. Accumulator groove: accumulates residual combustion gasses reducing top ring flutter and improving seal. Pin oil lubrication by broaches and oiler to reduce friction and increase durability. Sup
