we've seen past 600 WHP here before, so not like it can't be done. But yeah bring to light the 900 ft lbs plus and the turbo didn't sound crazy either. 600 plus on the dyno makes a lot more noise lol, not even talking muffler noise either. The engine is screaming up there.
But as it made more than my built Cummins I think this is a big fish story lol Anyone can adjust the dyno for different settings, even your high gear ratio needs to be put in. Some have a 1.15 4th and like our cars about a .94 ratio. So if you higher your WHP is higher than you actually made. With our .94 were really making more power if set for 1.00 gear. Either way they made a mistake lol
