I recently bought a 2.8H kenne bell Mustang GT. Car was tuned prior to me owning it on the pulley setup that is currently on the car. I was digging through all of the extras I received and came across a pulley that is roughly 1/8in smaller in diameter and was wondering if I swap pullies, will it require a WOT retune?
Believe I recall spark is at 14* peak and the dyno graph shows its running on 11.6-7 A/F.
No diameter sizes on these pullies but all I know is at WOT it makes 16lbs currently. Im assuming the pulley im looking to put on will produce 17-18lbs.
Any info is great!
