There are non track guys posting in that thread that have never done a track day in their life. The track was repaved last year, explains the fast time.

Looking at both ACR times (on several tracks) there is a several second gap (at least 2+ seconds) between the two. Yet on this course, they are under a second. Its probably because the gen IV acr attempt was after a repave.

I believe the GT500’s Grattan time was super fast because of the repave last year, August 2018.

Agreed. But, this car still weighs over 4000#. A repave on a short course like that, would be good for 1.5-2 seconds at the extreme high end, in my opinion.

I know, what ford did is amazing, im a fan of the car, not a fan of the weight. I think this thing will be eating tires like nothing because of the weight.

Worse than the Gen V ACR eating Kumhos? lol

I dont think they’re the same thing, the ACR already starts with a thin tire and the faster you go the more the car plants itself because of the downforce. This GT500 has way lower downforce, but has much heavier weight.

Ford posted how many hours and tires they used, I think it equaled to 1 hour at the track. Kumhos last longer than 1 hour of track use right?

Bill Johnson said 3,000 laps on 64 sets of tires.

My only question with that is, did they swap out sets of tires when they were toast, or when the lap times start dropping off by enough where it wasn’t favorable for them to keep running them?

Chatted with a Ford Engineer over a year ago and was told the car would be a major surprise. They worked more on making it a track car , than a drag strip king like in the past. Hard to believe it will be as fast as an ACR, but if it is close that will be an achievement in my mind. All this fun, fast stuff coming out just makes it harder and harder for FCA not to bring back the Viper. It will be different, just like the Vette and the GT 500 , but I believe the pedigree will still be there – folks will know it is a Viper!

Nice posting 13 Cobra!!

I sold all of my allocations before I heard about how big of a track monster it’ll be…. I may end up with a 2nd year run of one, especially if they perform like I think they will.

Surely you can shed 200-300# fairly easily. If I want to get crazier than that, I’ll send it out to AZ Vipers and tell him I want a light car…haha

Having owned a previous generation GT500 and participating in those forums, I read several articles and there were some impressive lap times. With that said, it was just one lap and when you read the rest of the story it was apparent the car could not sustain those lap times. Tires and brakes along with supercharger heat soak were constant problems and one lap does not win races. As capable as the new GT500 is, it is still a heavy car and will have similar issues. My GT500 (which I sold recently) will absolutely be the last forced induction sports car I will ever own.

That's fast

In the video the only comparison is to a car with about 450rwhp…but the difference down the front straight is ridiculous.

Arizona Vipers said:
It's not just the power difference, it's that DCT tranny too.

Agreed. I’d love to throw one in a Viper.

Dealer cost on the transmission alone for the MY20 GT500 is $24,870.

Arizona Vipers said:
Yeah can't be done, not the way factory does it. What makes a DCT so much faster on track is much more than just the faster shift times. It's the software that works together with everything, rear end, steering angles, slip etc. If you shift a manual let's say in mid turn it unsettles the car. These DCT cars can shift ANYWHERE and the software works with everything to keep the car settled. It's just a massive, massive unfair advantage EVERYWHERE on a race track. You basically just point and shoot and let the computer do everything else. Look at the GT3 running 6.55 at the Ring with 500hp. LOL Anyone that tracks a Viper and has to run against GT3's with good driver's knows what I'm talking about, it's frustrating. IMO the ACR woulda been 6.49 at the Ring with a DCT and smaller wing.

Oh I know it’d be impossible [read as: EXTREMELY EXTREMELY EXPENSIVE], but it would sure even the playing field.

I ran against some GT4 Mustangs, a GT2RS and a few other cars with very quick DCTs a few weeks back, and it was beyond frustrating.
