1999 Ford F-150 Lightning Kenne Bell Blower Swap
Boost Curves with 3-inch Blower Pulley
If there is one thing you can say about the gang at Kenne Bell, they are thorough. This graph is an example of that attention to detail. Every possible parameter was data logged during the testing on the Lightning. Here is a comparison between boost curves generated by the Eaton (lower) and the Autorotor (upper). The test was run with the same stock crank and 3-inch blower pulleys. Note the difference in boost curves generated by the two superchargers. The curves are similar, but the Autorotor offered more overall boost pressure through the entire run. Not surprisingly, the motor produced more power with the Autorotor, even though the pulley ratios were identical. The results of the power runs can be seen in graph. View Related Article
