[QUOTE="na svt, post: 11346294, member: 35346"] [B]Poor cam timing is the reason 4v engines make no tq, require steep gears to be quick and spool turbos slowly.[/B] With a stock runner length intake and proper cam timing you can get a 76mm turbo to spool quickly. They dyno sheet below shows what proper cam timing can do, the higher tq and mid range power translates to much quicker turbo spooling and better driveability which is needed with the turbo friendly highway gears. With low compression proper cam timing is even more critical. The graph shows a stock Mach with 96-98 cobra intake cams (degreed and undegreed) and stock exhaust and intake manifolds.
