As the testing progressed, the W2W team kept noticing the boost for the engine was only in the 9-psi range at peak rpm. They felt the engine should be seeing at least 10 psi or more, so they ordered a set of slightly overdriven pulleys from Dyer's Blowers in Summit, Illinois. The crank pulley needed to be redrilled to fit this application, but otherwise, the pulleys bolted on and netted a little boost in overall power. The final analysis was that the 6-71 blower either needed to be spun much harder or an 8-71 blower needed to be called in to service the big-block Buick to more horsepower. But that will be a project for another day. We learned a lot, the car is much more consistent, and it made a little more horsepower along the way.
