Ezareth Posted February 11, 2011 Report Share Posted February 11, 2011 Just got a Ford publication in the mail that says the top speed on the 2011 GT500 is 160 and the Boss 302 is 155. Also has a bunch of boring propoganda on the car itself in the magazine but nothing interesting other than that "fact". Has anyone had a chance to hit the governor on their 2011 GT500 and see what it really is? I don't have the roads around here to safely do that.

TrakRat Posted February 11, 2011 Report Share Posted February 11, 2011 I ran into my governor at 159 on the gauge repeatedly. I dunno of it was off as I didn't have my magellan with me. Link to comment Share on other sites More sharing options...

Torched10 Posted February 11, 2011 Report Share Posted February 11, 2011 Anyone know what the top speed is with the governor disabled? one of our members did one of those 2 mile runs at an airport in Fl about a year ago--my memory is that he hit 165 with the govenor off--he also put some shielding under the car to improve the aero--he had at une on it as well.That was with a 2010. These cars are not aero friendly,and i would think that would limit the top speed alot Link to comment Share on other sites More sharing options...
TrakRat Posted February 11, 2011 Report Share Posted February 11, 2011 I heard that they reach to speed at the top of 5th, 184 @ the rev limiter. Link to comment Share on other sites More sharing options...

Cdvision Posted February 11, 2011 Report Share Posted February 11, 2011 I heard that they reach to speed at the top of 5th, 184 @ the rev limiter. +1. I also heard that. That's what the SVT head guy claimed. Link to comment Share on other sites More sharing options...
Ezareth Posted February 11, 2011 Author Report Share Posted February 11, 2011 I heard that they reach to speed at the top of 5th, 184 @ the rev limiter. The real question is: Was the top down?

sportscars Posted February 11, 2011 Report Share Posted February 11, 2011 My brother and I had his Vert to a GPS indicated 174mph last year in Terlingua. Mark Baranco hit 180 in his super snake. We did have a 2011 there but I dont remember what he hit. Link to comment Share on other sites More sharing options...
jerseygator Posted February 11, 2011 Report Share Posted February 11, 2011 ...These cars are not aero friendly,and i would think that would limit the top speed alot I'm not so sure about that. If you watched the series "Supercars" Tanner Faust takes a 1000 hp twin-turbo'd 2011 GT500 to a top speed of 190 in the mile run. His comments were that it was a great ride up to speed. I'm fairly certain aero dynamics were not changed on this car. Link to comment Share on other sites More sharing options...
Firekiller Posted February 11, 2011 Report Share Posted February 11, 2011 Tanner's car had a kenne bell s/c, exhaust, and cams. and they even forgot to take the governer off. They figured it out and thats when he hit 190. The Camaro had the twin turbo's. Link to comment Share on other sites More sharing options...
Bill Hamilton Posted February 11, 2011 Report Share Posted February 11, 2011 .............................. I have bumped my redline to 6500 with the idea that I *could* break 190. (Hypothetically on a closed course, with a pro driver, yadda yadda) Are you running 6500 rpm redline stock or with a few mods? Not that I want to bump mine up, but I hit the limiter all the time in the lower gears. Unlike other vehicles in the past, you don't feel a power drop off or hear the engine straining as it climbs. I've actually set my shift lite and buzzer at about 5800 just to keep it off the limiter but I still hit it occasionally. That's on a stock 2011 with no mods.

JWG223 Posted February 11, 2011 Report Share Posted February 11, 2011 I have read 155 governed, but 185 with it removed according to one magazine test that I fully admit to not knowing the reference to. Link to comment Share on other sites More sharing options...

At this point my car is stock except for a tune. I felt a few extra RPM would be helpful on the road course in a few situations, especially since I'm used to a car that happily lives at 7200 rpm.

Ok, lets see now, Tanner hits 190 with 1000hp going full out,and some hit 180 with a stock car---HMMM!I know some of the 11s have a sealed undercarriage, maybe that makes the diff--but not a 10 Link to comment Share on other sites More sharing options...

Has anyone had a chance to hit the governor on their 2011 GT500 and see what it really is? I don't have the roads around here to safely do that. I got the same booklet in the mail and also noticed the same "fact" regarding the 2011 top speed of 160 mph vs. the 2010's top speed of 155 mph. I *know* the 2010 is speed limited to 155 MPH from the factory and it has been tested/proven by quite a few TS members with their speed indicated with a GPS. The in-dash speed indicator (speedometer) is NOT accurate so anyone claiming XXX mph (anything over 155) by the speedo needs to realize that they are NOT going to get their car past 155 without first removing the OE speed limiter or modifying the VSS to fool the PCU. I would however like to hear from anyone with a GPS in their 2011 that has topped out their car to see of the stated 160 MPH is true or just more Ford hype.

TrakRat Posted February 11, 2011 Report Share Posted February 11, 2011 Tanner hit 190 in a mile, not as the terminal velocity of the car. This was in my Cobra, but I had 16 miles to do that in. Link to comment Share on other sites More sharing options...
03reptile Posted February 12, 2011 Report Share Posted February 12, 2011 All 2007 through 2011 GT500's are governed to 155mph from the factory. If your car has not been modified, that is when the governor kicks in. Anything more is speedo error if the car is stock. Link to comment Share on other sites More sharing options...

2010KonaBlueGT Posted February 12, 2011 Report Share Posted February 12, 2011 What is VSS? VSS=Vehicle Speed Sensor. If you cut every other tooth off of the tone ring (the ring on the output shaft in the trans) the VSS will tell the ECU that you are only going half as fast as you really are so your speed limiter wouldn't kick in until 310 mph! In other words, it won't limit the vehicle speed to 155mph like the OEM PCU does and since there's no way in hell a Mustang COULD ever hit 310mph, it will allow you to hit terminal speed unlimited. Just use a windshield mounted GPS unit for your TRUE vehicle speed, which IS accurate. There's more than one way to skin a cat.... Phill Link to comment Share on other sites More sharing options...

BDrool Posted February 12, 2011 Report Share Posted February 12, 2011 FYI GY F1 tires have a "Z" rating with a "W" service description. This means the tires are rated for more than 149mph, "Z", and the "W" is maxed at 168mph. The GY F1 G2 tires have a "Z" rating with a "Y service description. same except "Y" is good to 186mph. Just thought y'all would want to know before you take limiters off and go to that top end, however, the G2's seem to be perfectly matched, speedwise to any current model GT500.

GAFSoldier Posted February 13, 2011 Report Share Posted February 13, 2011 I be driving my 2010 GT500 since almost one year now in Germany on the Autobahn and on the Nürburgring. So far my numbers for the 2010 are 191.33 mph on the Autobahn and 186.26 on the Nürburgring. I also had a 2011 GT500 with SVT package for some days for test driving and the numbers are almost the same (191.86 on the Autobahn and 186.25 mph on the Nürburgring), but I must say the aerodynamics feeling was better with the 2011 on the Autobahn. Because about the bad aerodynamics from the GT500's I must warn everybody to drive faster then 160 mph for a long time if you be not a good driver because the handling is getting really bad.
