Are those #'s off a dyno and compared to a baseline dyno? If so, were they the same dyno? I find it hard to believe that those mods add any more than 20-25 RWHP unless the gain on the 5.0 for a tune is far and above the 4.6.

Yes, those are off the same Mustang Dyno. As stated before I worry about Mustangs because they can so easily be "Hotrodded" by changing the "Roller Mass" and "Resistance" Files. A couple of keystrokes and and an instant 50 rwhp. Not that Evo would do that. However that baseline was run on a very green engine.


One thing is the exhaust on the 5.0 appears to be pretty restrictive with 2.25" Tubing expanding to 2.5" just prior to the rear axle which is then flattened when going over the axle.

My most optimistic guess would be 31 RWHP from the mods + 5 RWHP from additional engine break-in.

Offroad X-Pipe - 12 RWHP (Based on 8 RWHP on 2005 3V and 15 RWHP on 2010 GT500)

Straight Through Mufflers - 8 rwhp (Based on 5-6 rwhp on 2010 3V)

K&N Repalcement Filter Element - 4 RWHP (Based on 3 RWHP on 2005 3V)

Tune - 7 RWHP (Based on 12 RWHP 2005 3V equates to 16 RWHP on 2011 - 9 RWHP Ford already got 87 to 91).

On the otherhand I would not be suprised if it was more like your 20-25 RWHP either.

PS Thats absolute SWAGGING it and total ricer math.... but what you gonna do when the Railroad is holding your car hostage!

Cool, Gene. Thanks for the breakdown.

maybe I'll be eating this later...but I have a hard time believing they got +40 crank HP and +36 flywheel HP...from just basic bolt-ons and tuning.

seems like the '11 models only have 11% drivetrain loss based on Evolution Dyno #'s.



wonder how restrictive that exhaust is at 2.25"? very weird that Ford would run that small of piping on a 400+ HP Factory car

They put that crappy exhaust on there to entice folks to change it out

I've said it before: While Ford may threaten to void warranties over the modifications (read: Limit after sale expenses), they also build these cars for enthusiasts who want the satisfaction of pulling another 20% HP out of them (read: Increase sales and marketing excitement).

Damn they just ran a 12.04 @ 117 with those mods on drag radials

Well I'll put my foot in my mouth haha, very impressive numbers. Its looking like its gonna be bolt on 5.0 vs f/i 4.6...

It also says they blew the clutch ...

I saw it today unloading from their flatbed truck. It has good sized slicks on it now.

1.96 12.61 @ 108 on Pirellis. Low MPH was due to clutch issues. Hit the limter at 110 mph and let off. It would not have held 5th (Darn 3.73's).


Disclaimer: I dont say that 11-12% drivetrain loss is automaticall wrong but I don want to caution people on assumptions of this type.

Insufficient info to conclude 11% drivetrain loss. If you assume the dyno is 100% accurate (big assumption) and use the 416 bhp (actual SAE J1349 Certification Results) you do come up with only 11.4% Loss.


However thats overlooking the fact production engines vary... Ford only signs off that the majority of production engines will make +/- 2% of the test engines. Thats 408-424 bhp assuming the engine isnt an outlier. At 424 bhp the loss could be as high as 13% before we even tackle the issues of dyno calibration.

PS The Evolution car is a production car ordered via the local dealer in case anyone wondered if its a "ringer".
