Ok, I know that having an aftermarket crank pulley is bad for the sc due to lack of harmonic balancer. But... has anyone tried using lightened (not underdriven) pulleys for the accessories only. Unorthodox has a set (Ultra A) of acc. pulleys for your waterpump, p/s, and alternator.
If anyone has tried this, please speak up and share your experience/ hp gains.
Any other comments or thoughs would be appreciated.
