The 86a is, I believe, even more aggressive and loses more low RPM torque to pick up high RPM power.

When I try to simulate the hp and torque output of a stock 2.0 using DeskTop Dyno I find that the hp and torque numbers are better with the default cam specs that the software uses rather than with what (I think are) the Webcam 86a specs. Same thing happens when I try to simulate the output of a 2270 cc motor. I wonder how accurate the software is? I should ask Wolfram Research to consider adding an engine simulation
application for Mathematica.
