Dadstoy's Dyno

[Jerseyboy 62]

That graph of his shows classic knock retard. The 392 runs a leaner AFR and more optimal timing from the factory then the old 6.1. It's possible that it leaned out a little with the new exhaust, or could have just been false knock picked up by the knock sensors from the new exhaust. His Dyno Operator should have been able to point this out to him. Next run should include an AFR trace to see where its at. Other stock 392s I've seen are in the 12.2-12.5AFR from the factory. I doubt the exhuast really gave him much in the way of HP though. The 392s are already 2.75 or 3" with straight through mufflers from the factory. The only thing he gained was probably some noise....

All I did was floor it, Tanks is the video master.

They let you drive it on the dyno? When I had mine dyno'd, the shop owner did the testing.
