We recently tuned a 2013 GT500 here at Steeda Autosports whose only modifications included a 10% overdrive pulley, Kooks Long Tube header system with high flow cats, and a touch of our custom dyno tuning.

The difference? An additional 96.7 horsepower and 90.34 ft/lbs of torque at the wheels! Here is the dyno sheet.

Needless to say, this car is now much more fun to drive! While the peak to peak torque gain is 90 ft/lbs, from 4600rpm to 6200rpm the torque difference is well over 100 ft/lbs through that particular range!

 

^This is the setup I'll be looking to do someday.

They did not change the intake or throttle body?
I've noticed most '13 GT500 owners who mod do those also. Mostly using the JLT intake and Cobra jet throttle body.

 

Finally, just what the 2013 GT500 needed more power! lol

All joking aside it is amazing that you were able to add even more power to this car with such modest modifications.

 

I am impressed. Thanks for sharing the Dyno Data.

 

Awesome gains, however, as a 2013 Shelby owner I can honestly say I don't feel the need for more power. Certainly not more torque, but I'm not everyone.

What I am interested in is suspension upgrades for those of us with the 2-mode adjustable dampers. Has the Steeda team done any suspension investigation specific to the 2013 GT500 ?

EDIT: And better grip! If I forget how powerful this car is for 1/4 of a second, my *** slides like butter on a hotplate.

 

We have several suspension upgrades that are currently offered on the 2013 GT 500.
