- adjustable cam pulleys? What does it do?
- to adjust ur camshaft settings... either advance or retard... advance for better pickup, retard for better top end... people usuall retard it for higher bhp gain at peak power rpm.... advancing the timing till help throttle response at low end, but sacrifice top end power... adj campulley is important to get a good tuning for high camshaft...
did u opposite it.?
i think advance should have more top speed or top end and retard have more stable idle and better pick up?
