Hello ZL1 Family!
This is my first post so be gentle
. I have searched this forum to find answers but still have some questions.
I have a 14 red hot ZL1 M6. Pretty much bone stock except for Rotofab CAI. Not tuned currently.
I'm building my bank of parts up to do my first set of mods. so far i have:
-ID850s
-1 7/8 SS headers w/ connection pipes - no cats.
-Wrapped the headers also 
-ATI H-balancer
-Catch can
-1.75L IC resevoir
-Afco HX - no fans just the hx
My goal is to be in the low 600 to 630 rwhp range without having to do a cam install. Also, I would like to maintain the drive ability of the car since its my DD. I don't plan to race it, or take it to the track. Just want to enjoy the car on the street and smoke mustangs when I see them
Ive seen 2 posts on this subject and one guy had the same setup with the 9.55" / 22% pulley and dyno tuned (dyno jet) at 630rwhp. Another guy with similar setup was at 585rwhp (
not sure if it was a mustang dyno or not). Both did not mention a BAP or cam. Just the 22% pulley and supporting mods listed above.
On several posts Ive read where anything over 18% pulley, your not benefiting from a the stock cam and need to upgrade.
Id prefer to do a cam at a later point in time if possible, but I am committed to get to my goal rwhp as well.
Questions:
-If I go with a 22% pulley, do i need a BAP? Do I need a cam? If I did a cam, is a BAP needed still?
-If I went with the 18% pulley, no cam, would I need a BAP?
-If I did go with a 22% pulley and BAP to support it; does anyone have any good cam suggestions that gives you a slight choppy idle, good HP increase, but maintains the DD drive ability? I was thinking of the BTR Stage 4??
(If I do go with a cam i would be upgrading the springs and push rods,etc. /Stock rockers tho).
Sorry for the book, just trying to be as specific as possible. Any input is appreciated!
Edit: Forgot to mention I plan to run 93 gas only.
