Do you mean serpentine belt or toothed blower drive belts. Cause they will eat power like crazy without the super charger.
Even blowers try to avoid using them unless absolutly needed. They use serpintine belts for normal street applications. Gilmore belts will eat power like crazy.
By crome v belt pulley they are dirt cheap and dont use alot of power and also avilable in all sizes.
I have never seen a toothed a/c belt. I dont think anyone makes an ac clutch for the toothed belt but water pump and power steering are fine.
