  • This crank helps give the S50B30 & B32 Euros a wider powerband with much more torque under peak output, giving you the edge off the line and out of corners when you need it most.
  • Commonly ordered compression ratios: 12.5:1 Use with Race Fuel only; 11.5:1 Good for high octane pump gas; 9:1 recommended for turbocharged engines
