- Worth noticing
- The homepage reports 348 dyno pulls from 181 tests, alongside 933 head-flow sheets and data for 32,350 US towns.
Field notes
The page describes a workflow that connects catalog choices to predicted horsepower and torque curves, then checks combinations for issues such as injector sizing and compression on pump gas. It reports data from 29 dyno shops and includes elevation-specific estimates; its accuracy figures are presented as site claims, not independently verified results. Plans are listed at three price points, with up to 10 projects included.
