My stock 6.0 only made 300/300 on a Mustang Dyno with a Catback and air intake only. I was a bit disappointed, but I'm not too worried about dyno numbers either. It was only on there to get the tune str8. I'm sure a cam swap would be good for 40 more rwhp or so, and then headers, elect. fan, etc.....I could see one getting to 400 n/a with a bit of effort.

 

considering stock 6.0 on the dyno im on are only makin 230-240 stock..my ex boss knows how to do it and has done it before, theres some things you can mess with on a mustang dyno to make them read 65-75 more horsepower..i was up there a few weeks ago and an 06 bone stock 4.6 mustang made 305 hp with the dyno made to show higher numbers..before he knew how to do this they were doing 230-235.. he found out how to do this on some forum, owners of mustang dyno's are getting tired of people bitchin about how their cars are makin low number and someone found out how to fool the computer on the dyno and posted it how to do it

 

I 've heard about that too.. They can change the altitude and a couple other things and it makes a pretty drastic difference.

 

Your numbers seem realistic in comparison to mine. I've ran a best of 14.1 with simillar HP, on a Mustang Dyno as well. The only mods I have are a Cat-back and an AEM intake, and a Yank converter, but it is a 6.0L.

 

it has to do with the weather station and thats apart of it
