You can put on a Unorthodox Racing Lightweight crank pulley(stock Diameter) which weighs about a pound. Your stock crank pulley weighs almost 8lbs I believe. That will free up some HP and TQ for you all across the powerband.
I did that mod when I had my timing belt replaced and it was a great mod for the $$$$

Straight from the description of the underdrive...
"This version of our crank pulleys increases performance because they underdrive all the accessories (15-20% more power)"
a smaller pulley has less mass to rotate. so you'll get more power.
BUTT, with a smaller pulley you get undesirable effects because it does underdrive the accessories.
"This means one you air conditioning is on our crank pulleys give you more power back to the wheels by not letting the air conditioning compressor rob as much powerHowever, we do not push the amount or percentage of underdrive too far for two main reasons. First, it is important to keep charging systems, air conditioning, power steering, and water pumps moving fast enough for every day driving. Second, not much horsepower is gained from extreme underdriving. We always keep our underdrive percentage under 20% which is what allows us to maintain factory specified outputs for all your accessories. Our testing has found for most vehicle models you can upgrade your stereo to a system of up to 600 watts (RMS) and not have any charging problems."
Also, people that have gone F/I with the super charger route, they don't get full boost because its being under driven.

When I did this on my truck I also purchased a OVERdrive pulley for the alternator. This acts as a balance for the electronics/power!
I plan on doing this mod on my TL next year when I perform the 100K Maint as well! It is the perfect time to do this mod being they are taking the Crank Pulley off anyways!

I have read somewhere... Maybe when i was building my RB25 that URP may hurt the engine as the is a damper the help with engine vibration built into the stock one and this vibration can hurt the engine over the long haul... Thoughts? I just ordered a J-Pipe and if people have been using one for a long time with no issues ill get on getting one!
