One of the shops at Buttonwillow has a dyno that's not too expensive.
Chris, what's the advantage of Rabbit rods?
That would be nice, I'm sure cliff would be up for it.
The rabbit rods fix the fact that the 914 didn't come with a very good rod-length ratio. The 914 engine doesn't "breathe" very well, and the increased rod-length ratio improves that.
If you want the physics explanation, you get that Work equals the dot product of the force and direction vectors.
W = F • d, which simplified for a 2-dimensional scenario becomes W = F * d * cos ( theta ). If you increase the rod length you decrease the change in angle caused by the sweep of the connecting rod and minimize the potential range of theta.
Steve, you've driven Cliff's car, right? This rod length change manifests itself in a bunch more bottom end power.
