Test fit the new 8MM HTD belt drive for the Whipple on my spare 1UZ V8 last week. I think it turned out nice, all that's left is to figure out where to mount some kind of tensioner pulley and fabricate the mount for it. One of the nice things about Curvilinear belts is I only need like 7 to 10 lbs of tension on the belt so It should be a very low drag drive. Trying to figure out a way to add a second keyway to the crank without taking the crank out of the car. I might be able to do something with the stock keyway to add some length to the stock key so it extends farther into the crank pulley.
