We just wrapped up our development on the 2010 Ford Mustang GT and have some dyno numbers for those curious about the output of the retuned 4.6L.

What were the actual HP numbers with the Exhaust?

WOW! nice numbers for just a 3" cat back

it gained 15hp and 17tq from the 3" catback? wow how much are they

wow pretty nice gains

Sorry to get off topic, but if the blue curve represents stock, then it has 290 hp stock. Estimating a 15% drive train loss, that mean it's ~341 hp at the flywheel. It's underrated and could be a sleeper!

Yeah, that is what I was thinking. 290rwhp stock is pretty crazy, that is about 25-30rwhp over the current S197.

And that thing does sound badass!

Damn. Either that's a very generous dyno.........or the new GT's have a bit more than Ford's letting on about. Either way, over 300rwhp with just a catback is lightyears better than the 05-09's capabilities.

Remember that the 2010 is gonna already have an adaptive/aggressive tune and the bullit intake. So your not gonna see the big gains from the cai intake and tune like you did on the s197s.

sounds great kinda confused why a 3" system on an NA 4.6l made more HP I could understand on a fi 4.6 or the 5.4 motor
