Default Re: What Is YOUR Top Speed?

I used to live in Naples and had lots of friends in Miami and would make the trip a few times a month across the alley....

Be CAREFUL, they have helicopters and planes doing flyovers pretty regularly looking for exactly that, I got a ticket not far from there last Dec. 26th, merry Christmas to me I guess.....

I regularly run my roaster limited at 150 along Alligator Alley, but it always tops out around 149-153. This is not due to lack of pedal, it seems, but pure HP. Is it true that the XF is wired shut, or governed, at that speed?

If so, how is it accomplished? Fuel starvation? ... or ignition retardation? How do you 'un-wire' your SRT6 to do better with a tune? Also, I understand that manufactures will limit top speeds based upon OEM tire speed-ratings. True or no? Some say the XF may tend to 'float' somewhat at high speed. Mine feels firm and smooth as you'd ask (little hard on the rag top), but can this sensation be associated with tire expansion? I'm running a decent ultra-high performance summer Bridgestone.

Thanks for any insight.
