Product CodeCHM-FEULINGP-1346
  • Aggressive pulling power with a “nasty” sound, the Reaper 521 grind will shine in 114” and larger cubic inch engines with added compression ratio
  • Ported cylinder heads are not required, but will complement the cam and add even more pulling power throughout the range
  • Stock throttle body produces an excellent powerband; use of a high-flow throttle body may increase peak power numbers
  • A high-flow exhaust system and air cleaner is highly recommended for optimal performance
  • EU: Aggressive pulling power with a “nasty” sound, the Reaper 521 grind will shine in 1,87 L and larger cubic inch engines with added compression ratio
