Inliners International Forums General Discussion Hi Performance Dyno day for a 292, Need help

Since most people consider a dyno to be the absolute in real world data acquisition, the fact that you were even able to get within 5% of the established results from one is something to be considered. Some of the very high end software used by many of the Winston Cup teams sometimes misses the mark by that much. 5% at 200 HP isn't that much to think about, but 5% at 800 HP is a whole lot to miss it by.
