I'm new to this forum, member of Club Lexus. I bought the underdrive pulley for the Solara 99-03 and installed it on my 1998 Lexus ES300 last weekend. I had my local Lexus dealer install it, they charged me $107.00 and took less than an hour to install the belts and pulley. I've noticed better throttle response, it wants to go once I press on the pedal. Too early to tell if there is an increase in fuel economy. But, the underdrive pulley seems to weigh approx. 2 lbs lighter than the OEM and is one inch in diameter smaller than the OEM pulley. The only other difference I noticed is to alternator ouput, decrease a full volt. When in park and at 600rpm, I'm putting out 12.54 volts and when the rpms increase, so does the voltage output. Some members on the Club Lexus forum are concerned this mod will ruin the engine or throw off the camshaft balance.
