Underdrive Pulleys

I've looked here and there but don't see any listed domestically.
I would be inclined to have a buddy turn some but I suspect if I want to remain with the stock belt, it will require two or more pulleys to be made. The idlers are pretty small and I don't know what RPM they turn let alone reducing them...bearing failure may be a concern. Trying to keep with a stock length belt that is.
Most underdrive kits are water pump and?

a little writeup on underdrive crank pulleys
Power gains are obtained in two ways. First is the weight loss. An average of 2.7 HP is gained from every pound lost off the crank shaft. 85% of UR gains are from weight loss. The rest of the gains are from underdriving, which accounts for about 15% of the total gains. All of UR underdriving is done with the crank pulley, not the accessory pulleys. This is done so maximum weight loss can be achieved at the crank where most of the horsepower gains are found.

Thats why I said the "search is getting near". More and more people are finding out that there is a demand for performance parts for the V8 toyota.
And FYI i did pay attention to Jbrady when he posted on Lextreme. So please try not to lecture me, read my post and read it carefully.
