The 5.7" crank pulley used along with the smallest supercharger pulley available for any supercharger should be enough to put most guys past a desirable amount of boost for most setups. I understand this might not be your case but when we make pulleys we have to make a bunch of them and unfortunately there is not enough demand currently to justify making that additional size. If you're interested, we can have a one-off made for you but it will cost a bit more.
