Really could be down to driver?

I'm not too surprised by this, the GT500 has a better power to weight ratio. But in the end the guy chose the Boss. That's not surprising either.

 

cool video,

 

The black/red LS looks very striking out on the road. Ford killed it with that one.

 

I'm going to do my own comparison in a couple weeks. From the get go I figured I wouldn't beat my BEST GT500 lap time with the Boss, but that I'd get to run a lot longer with less heat soak and be much easier on brakes and tires. What the comparison doesn't tell us is average lap time for a typical 20-25 minute HPDE session. My GT500 typically started heat soaking after 4-5 laps and started bogging even though it didn't overheat with enough cooling mods. During the peak summer months you just didn't try with the GT500, so I'm hoping I don't have to manage the Boss track schedule with the forecast.

 

Not sure if its the editing or is the stock GT500 that much louder than the Boss and GT? What tires come on the GT500?

 

Interesting to note it was the LS model that they used, so the standard Boss would be perhaps .5-1 second slower.

I'm a bit surprised because the Boss was designed for the track so I would've thought it would edge the GT500 in that arena. But on the other hand I'm not surprised, the GT500 is Ford's top mustang so they aren't going to have a lower priced model beat it.

 

freaking epic! long live the stangs! (in all trims lol)

 

I haven't heard a Boss in person, but I was really shocked at how loud the GT500 is in stock form. When you step in it, it freakin howls. Sounds fantastic.

Tires are F1 Supercar G:2s on the 500.

 

my neighbours say they can hear me a block away and i never rev it or drive agressive in residential areas.

just a rumble is how they describe it

first car i ever owned where i didnt want change the exhaust

i hope the boss doesnt let me down if i end up with one in that dept

everybodys that has gotten one seems quite happy though

 

Same here, its just enough to sound great, but not be obnoxious.

 

Considering the track (Streets of Willow Springs), it clearly favors the GT500 with its long straights and wide sweepers. A soild horsepower track. I'm not making an excuse for the Boss, but both cars can be course dependent. On a handling track the Boss would definitely have the advantage.

With 1:2X lap times weren't they running the short course?

 

My 2011 GT500 has dramatically better cooling then even my 2010 GT500. It doesn't run anywhere as hot. Even cooler than my 2010 with the Afco Dual Fan heat exchanger.

 

Gotta agree with you on the 2011 GT500 exhaust. Sounds great when you step into it. It's also the first car I have no desire to change the exhaust on. Just try and find a nicer looking tips for it.

 

I saw the photographs of your new GT500 and it's gorgeous. Any chance you'll be taking it out for any local track events? I'd love to see it in person.

 

That's good they were able to improve it. Do you run an ECT or Oil temp gauge or have any datalogs? I run a huge twin fan heat exchanger and C&R radiator with oversize intercooler reservoir. I also dial down the hp/tq from 640/625 to 575/545 using a 2.9" upper blower pulley versus the 2.6" I run on the street. I was still peaking IAT2s toward 160 and ECT into the low 230s with that setup in 85 degree ambient. I met David Murray up at BIR last summer at a PCA track event. He ran a Ford GT in the ALMS series and he said they were always battling the heat soak issue. They got pretty inventive with how they plumbed the intercooler and made it work, but still sounded like it was a battle to keep it cool on the road course. He was a really cool guy, even went out and sat at turn 3 and watched us for a session and coached us.
