Wow, That is a ton of power. I called whipple and they told me to run a 3.500 pulley to be around 10psi with this cam, headers and exhaust. I am thinking that may be a little drastic. I just really want to be as safe as possible. Hearing what you guys are seeing with 3.875 and 3.625 pulleys I am thinking the 4.00 is probably the safest way to go if I would like to stay 8-10 psi.
