Hi, just a couple more questions regarding a supercharger,1, what is the recomended compression raio for a 4.6 v8, is the standard ratio to high at 9:35:1 or would that be ok with low boost? Also what would the pulley dia be on the supercharger be, many thanks David. (ps forgot to mention its an eaton m90)

Basicly all answers are given in your previous topic.
I am running 7 psi on a 9.35 block but I am not shure a M90 is capable of doing this on a 4.6. It shure is on the end of its efficientie.
With the calculated 5 psi you have no worries.
