I have been having an ongoing rivalry with my buddy's 2014 camaro SS ls3 manual. He has every bolt on imaginable (intake, heads, cam, headers, throttle body, etc) I have a 2011 GT500. When I was stock we ran dead even over and over at every speed. I figured he was around 490whp. When I was at...

I have a 2011 w/ SVTPP and recently got an unbelievable deal on a 13/14 TVS take off. After installation it put down 606 whp/ 611 tq. Just for conversations sake how does it stack up to a 13/14 stock GT500. it seems I have a 15-20 whp advantage and 3.73 gearing, and the 13/14 has improved...

Good evening, 2011 GT500 SVTPP 28k miles stock suspension. Recently when I am driving over aggressive bumps I have been hearing a slight squeaking noise from the left rear suspension area, sounds like running over a mouse. It is tolerable now but IDK if it will get worse. I am relatively new to...

Looking for advice for a CAI. My goal is to take a few tenths off my 1/4 mile time. At the track yesterday my best run was 12.32@ 120mph, with a 1.9 60'/ 70-75 degrees outside temp, 500 ft elevation. I am itching for 11.99. My current setup: VMP pulley & tune AFCO heat exhanger Rouch Extreme...

Brought my car to get VMP pulley, tune, and AFCO heat exchanger installed today on my 2011 GT500. The car put down 537whp on the dyno. I definitely feel how faster the car is, however my boost gauge still only reads 9 psi. The boost is shooting up way quicker, and will be at 9 psi at 2,000 RPM...

I am having a friendly rivalry with my buddy. He shows up with a 2014 SS he bought last week,and all he says is it "idles funny". So we did 6 pulls, my 2011 gt500 is stock, only has catback. I was very surprised of the outcome. We were neck and neck all of the cleans runs (I missed 3rd a few...

I am looking to get a pulley and dyno tune for my 2011 Gt500. I called a local mustang performance shop, and they told me in addition to the pulley and dyno tune I would also have to purchase a handheld tuner, which puts the price well above what I was prepared to spend. To my understanding...

Will a 285 30/19 work in the front with svtpp wheels without any issues? It shows the diameter 0.6 inches shorter than the stock 265 35/19 on my svtpp wheels. I found a set for a really good price. Any feedback is appreciated.

I am considering getting a muffler delete for my stock 2011 GT500. I have read when one gets headers they will loose boost due to decreased backpressure. Will I experience this on my otherwise stock car with muffler delete only? Thanks

New member here. Last week I traded in a 2012 charger SRT8 Superbee for a 2011 GT500 w/svtpp. The power delivery is much different and it is huge step up. Here are some questions: 1) 2nd gear grind. Is there a solution yet by Ford? Should I take it in before the powertrain warranty is up...
