new 5.0 11.82 at 118

the crazy thing is he was granny shifting and the car is still spinning off the line so i think it's possible to pull 2 to 3 more tenths out of it. and then even crazier a 75 shot could possibly put it in the 10's.

The spin is helping the car more than hurting it, IMO.

He was shifting it well, although they didn't sound like powershifts till maybe 4th? My brothers 2006 GT is stupid easy to shift fast.

Very impressive indeed!

Correction. A Cat Back did next to nothing for the previous N/A 4.6L cars. These new 5.0L's are making a whole lot more power and have ability to walk it out to much higher RPM than the previous modulars. So I would imagine quite an improvement could be made by freeing up exhaust flow. Look what cat backs have done for the previous '03-'04 Cobra that were in the now new GT's power range? Or even the new GT500's? Seeing power increases of 40-80hp with exhaust and tune were not at all uncommon with these cars....and these new 4-Valve heads outflow both those castings.

I'm just going to have to remain skeptical until these cars really hit the streets and there are others out there getting similar results. I just find it very hard to believe that Ford put this much engineering into one of the best performing engines of all time, only to leave ~40hp on the table with a simple muffler swap and tune.
