Yes... they WP Pulley is $70... the Wizair is $200.... The P-log with coating and gaskets is $211...Thats $481... Instead...Screw being all pretty...Spend $40 on the intake... Get the Pacesetter headers for $359 plus the other hardware crap needed and then you could run an even smaller pulley... It won't be flashy under the hood...who cares... Your kill ratio would go up...
