why do you want an alum flywheel? they dont give any power for our cars. the heavier ones actually help keep us in the power band. our power band is only about 1500rpms tall. with the alum driveshaft i had, i could get out of that quick, but the flywheel will be 10x quicker as thats part of the engine.
sure it will rev quicker, but it cant sustain the rpms when you need it up top. the 3.8L's main weakness is its top end. you dont want to sacrifice what little you ahve to try to put some down early when we still dont have that much torque.
not a good investment IMO
