tryingbe doesn't, I never had an issue with a 120amp alt at night. Though I had my headlights relayed as well. Also porting the water pump and shaving every other fin off helps the motor spin up faster, and reduces cavitation in the cooling system.
1st thing I do is throw on a UDP, port and mod the waterpump and an aluminum flywheel. Makes the motor way more fun and rev happy without losing torque.
