URD 1MZFE Crankshaft Pulley fits RX300

URD Pulley installed
I strongly suggest you to install it. I just got mine installed after 5 months of delay. Right out of the shop the car feels lighter and acceleration is definitely better.
URD pulley is 1 lbs 10 oz, OEM is 5 lbs 1 oz (local post office scale), I know Lexmex weighted it at 5 lbs 4 oz. Shaving 3.25 lbs = horsepower gain at an average of 8.8. More importantly it is across the entire RPM band, from idle to redline.
Lexmex, did you notice any mpg gain?

I noticed a slight gain in the first two weeks and then it kind of trickled off. The trickle down in MPG might also have been due to my foot rammed to the accelerator 24/7. In the first week was when I also set my still current 1/4 mile record with that pulley on (weather was a little cooler then), so it does give you those 8.8 horses.
