EA888 3b is a fuel efficiency optimised engine - really mechanically quite different to the standard EA333gen3. The very high compression ratio and the cylinder heads optimised for swirl will really reduce the power potential!
If you want 300 - 500hp just get the Cupra.
Anything more than a simple re-map on the 190tsi will get expensive and complicated!
Same story with the diesels - the EA288 184 is again optimised for efficiently with high swirl heads - great for efficiency/emissions but really limits max air flow/power - so no point trying to tune anything more than a simple re-map.
Changes to the 2.0L EA888 engine. Audi made a number of design changes to the EA888 Gen.3 engine to realize the Gen.3B.
- The Audi valvelift system applied on the intake side.
- An increase of the compression ratio from ε = 9.6 to ε= 11.7 by decreasing the combustion chamber volume.
Audi engineers lowered the combustion chamber roof by about 0.9 mm, and moved the intake and exhaust valves—slightly reduced in diameter—axially downward. The positions of the spark plug and high-pressure injection valve and the piston shape was adapted to the new combustion chamber.
- Maintaining meaningful charge motion is a significant challenge with reduced intake opening times and valve lifts. EIVC extends the time between tumble-generation and combustion, and thus the time for the dissipation of charge movement. Further, the high compression ratio pistons (with reduced recesses) also negatively impact the development and maintenance of tumble.
To address this, Audi developed a new intake channel that produces a higher basic level of tumble; added maskings in the lower regions of the intake valves; and optimized the piston cavity.
- Changes to the cylinder head and basic engine optimizations.
