I’ve seen people saying they’ve gotten to 85-110 mph, I’d like to just say a “ clapped out “ one did 135mph in New York not too long ago so idk how fast a “ good “ one will go.( for anybody wondering )

 

Hopefully not on a public road.

 

My 09 with a 4.7 easily hits 110

 

05 3.7 can run 110 easily, but I was afraid to press the throttle to run more

 

05-hemi With the stock exhaust, the limiter kicks in at 115 miles, with an exhaust and muffler per bank, connected to the H-pipe system, the limiter kicks in at 115 miles. So, if it has reached 135 miles, it means that the limiter has been eliminated. But be careful, we are sure that the driveshaft is balanced, and can easily handle such speeds. Here in Italy, a guy with a Siverado, eliminated the limiter, it always went at full throttle, until the driveshaft broke and broke the floor of the passenger compartment. Luckily no one was injured.
