Ok, Went to the shop to get my Stock SS dyno'd. She put down 204HP at the wheels!!! When we checked the AFM it showed the mix getting really rich after 3500RPM. Anybody else experience this? Anyways, this shows that the 205HP publisized by GM may not have been wishful thinking.

The scan of my dyno run is in my gallery.

 

Look around man , almost all the stock dyno's are very rich . Mine was 10.0 at times over 3500 . Built in engine safety feature courtesy of Chevrolet

 

GM manufactors it like this to keep things cool and safe

 

most boosted cars are set to run on the rich side. under boost, a knock can be deadly.

 

205 is supposed to be at the crank, not at the wheels.

 

Not all cars dyno the same. We're lucky to see over 200whp. Manufacturers always rate at the crank.
