Then another person stated he had the SR version. Madmaxx says Roush rates it at 520hp, but it is putting out 507hp.
"It depends on the Engine I have the 427SR/TW and it dyno'd on the engine stand at 507 hp and 520tq".
All I am saying is if I paid for the 550hp version and it is coming up 30hp short, I would be calling somebody and asking them to explain the difference to me.
