Once you've freed up the breathing of a motor, the desire for more power doesn't stay away for long. The quest for more juice has plenty of routes to be taken, be they NA or forced induction. Regardless of which path you choose, it's wise to consider your engine's guts before jumping in head first. The parts featured in this guide are designed to create power and withstand the stresses associated with a highly built motor.
BLOX Racing
High Compression Valves
High compression valves from BLOX Racing undergo a heat-treatment process to increase strength and are then coated using black nitride to provide superior wear resistance and minimize power-robbing friction. These valves increase compression by approximately 0.3 points.
