Still no updates on the NFGT lap time at Big Willow? Feb C&D Lightning Lap article makes me even more eager to see the numbers.

You should check with Motor Trend.

Will be great if the GT outperforms the 720, but I doubt it will: the GT benchmark was the 675LT and the 720 is significantly quicker than its predecessor. Having said all that (and as I’ve said before) who cares? The GT is an icon, the McLaren is a car.....
Hopefully the aero will edge out the 720. But when the track version of the 720 comes out....game over for a lot of cars including GT. But I couldn’t care less..GT all the way!

Much respect to Mclaren though, they have upped their game in a big way. All other mfg are having to take note.

Totally agree... Can't wait for our turn in the GT process... Dream car for sure!

Just slap a Whipple or twin turbo setup on your 05/06 and you'll handily beat any of those cars. And for a whole lot less money.

There is no room for performance improvement on the NFGT motor without big tradeoffs. Thats not why you should buy a NFGT.

Some comments from Randy Pobst

"Yeah, it’s great, no, not perfect, quite, yet, yes one of fastest ever. And so gorgeous"

" I think it is soooo gorgeous and desirable"

"GT runs like a supercar"

"Still compliant, somehow, mostly. It does seems to hit the jounce rubbers (travel limiters) on a big bump going into Turn Nine at Willow. Never really noticed on other cars. But it does not destabilize the chassis."

Wonder if Ford encouraged them to give the GT another test in more favorable conditions (not 110 degrees).

Any updates on this thread? Interested to see what the NFGT did at Big Willow.

Facebook comments. He said the article is 2-4 weeks out.

Ron, the 720s is making closer to 775 flywheel HP, which isn't far from 200 HP/L. Just amazing.
Frank, I've seen they put down almost 700whp SAE. That's almost 175whp/L. The GT would have to make 612.5whp/L to match that.

Ha, Randy Pobst! I bet Sanjay could get the NGT into the low one twenties at Willow!

Easy fix, 265/35 ZR20 fronts to cure under steer and more aggressive brake pads. I assume drive by wire throttle can be programmed to provide any opening rate desired so that can be adjusted too.

Might be even simpler....I'd look closely at the alignment first.

Yes but sometimes that can lead to instability, my 991 GT3 had a similar issue, I tried rear toe, front toe out and more rake angle. Finally substituted 285/19 fronts for the 245's and the car is pulling more lateral G's by .1 to .2. Braking is also better because of larger front foot print and no stability issues.

That might ultimately help, but it can also create more problems.

A wider front tire will affect balance of the car that Ford (and Porsche) dialed in, which is in itself causing some degree of "instability," ie more oversteering tendencies.

Always best to start with the basics, which often get ignored, such as pressures and alignment, before taking drastic measures like changing tire size, which, in this case, means not only a 20mm wider tire, but a slightly taller one.

That's going to affect the ride height, which affects aerodynamics.

It might have unintended consequences with ABS and stability control, and possibly clearance issues as well. Modern exotics have very little tolerance engineered in for big changes to the car, such as a tire swap. It's not as simple as some may think.

Looks like Pobst was back at Willow Springs in the NFGT yesterday.

I always start with the easy minor adjustments, for example 2005 GT's had geometry designed to produce roll under steer that could be adjusted out which I did on my 2005 GT. Ride height can effect more than aerodynamics it also effects the roll axis so whenever making a tire size change I make sure ride height is adjustable to offset any height changes the ABS should accommodate minor diameter changes. I am just saying I went down all those roads on my Porsche before making the tire change and it solved the issue with no side effects. All modern cars are developed with the lowest common denominator in mind (the driver). A car that responds well to a skilled driver would be unsafe in the hands of an average driver so there is always room for improvement. It is a very small change that might very well improve the balance of the car. Since the car has torsion bars a spring change would be very difficult at either end.

Frank? I hope you aren't mistaking me for that pathologist with the porn 'stache. Oh, and your math is a little off too. 😁

Pobst said results are embargoed until the article comes out.
