ive got a sc and im putting in with a new cam f303 . ive got a double roller timing gears wuts should they be set at?advanced or retarteds and so how much.i was thinking retarted 2 degrees
get a boost/timing adjuster box... like a MSD BTM, so you can set advanced timing, say 12*....but when boost kicks in.. the BTM box with retard timing, say 1* timing per 1psi of boost...
Are you talking about cam timing or ignition timing?
I'd post in the supercharged/turbocharged forum and ask them about safe timing retard setups as the boost comes on. A lot of the more successful and streetable boosted combinations run chips to control timing and mixture as boost increases.
