the crank pulley is 25% smaller and the alt is 25% bigger so there is a 25% reduction on everything and 50% on the alt. now maybe i won’ smoke 1 alt a year. the new pulley is at least 15lbs lighterthatn teh stock one.
the SHO uses a harmonic dampner and is internaly ballanced. my concern is about me removing the dampner. the engine already has 216K and it has another 200K to go i don’t want to kill it becasue of a silly pulley.
