Hi.
Wanna up the boost by making the crank pulley bigger. I know the general rull that 1mm is 0.1psi but i already have 83mm pulley.
What size crank pulley do i need to make 15 psi?
Also whats the largest size i can fit withiut having to change the wter pump pulley?
Is there a general formula for measuring this when the sc pulley has already been made smaller?

Keep in mind all combos end in different boost with supporting mods. You know your boost now so this chart may help




Looks like you would want a 175mm or 178
