The dc5r crank pulley is 5.4in diameter right? I'll be running a similar setup on my new k20a but i am swapping to a larger k20a2 5.8in diameter crank pulley with a 3in boost pulley. Im looking for 11-12 psi @ 8800-9000rpm redline at 17000-17300rpm on the blower at redline. How high are you revving your jdm k20a?
