Viper ACR lap ring faster than GT-R Vspec and ZR-1
 

http://www.autoblog.com/2008/08/27/u...-22-1-w-video/

7:22 is the lap time vs 7:25 for vspec (unofficial because vspec is delayed well into next year) and 7:26 for zr1

Vid not working

That was freakin awesome. Just love the sound of that car
the vid on autoblog isn't working try the vid from motortrend

Now that is what I'm talking about. About time GM and Dodge are showing who's king. Time for the American Muscle haters to show their faces.

freeking loud!

nice.

Isn't the ACR essentially a production race car?

^ Yes.

Yep American CLub Racer. its like barely street legal. which makes me wonder if this is a fair comparison of cars. to me should be comparing this car to like tuner shopes like Mines etc. but that is just my opinion.

Yep, after reading several articles on this car 99.9% of them say this is something you wouldn't drive on the streets except in a pinch. It's pretty hardcore. i could handle it, but I don't know about the average Joe. lol

No matter which way you spin it, it's still a production vehicle that can be driven every day if you choose to, while eating everyhting up in sight.

Let's say the same thing about the Furai!

But damn if 7:22 isn't a VERY fast time. Congrats to Viper!

Man ever since the hype of the GT-R getting the fastest time...It's been beat twice...Wonder what will be next. Maybe the new ferrari F430 Scuderia..

So we are comparing this car

i dont know about you. doenst seem like a equal comparsion. its like a 14 year old boy clamining victory, because he beat up some 5 year old boy.

It may be just me, but while I have respect for the ability of engineers to force 600 horsepower through the power train of a car and give it a race-worthy suspension, and enough aerodynamics downforce to keep it pinned to the track, all while keeping it street legal...

I don't have any desire or appeal for the sheer amount of physical effort that is required to keep that car pointed where you want it to, nor for the ride quality akin to continuously drop-forging your vertebrae.

Watching the video didn't make me gush in awe, but cringe in sympathy until i remember that someone is deliberately paying for that punishment.

Sadomasochist apparently.

I also couldn't help but note that the driver nearly spent more time in countersteer than not, including on the straights. Motor Trend's comparison that included the ACR along with the other more mundane vehicles was almost entirely on smooth surfaces. The Ring is decidedly NOT a smooth surface, and while the time is impressive, I am more interested to see if the driver sets a time record for physical therapy recovery...

there are at least 2 mis shifts in that vid and lots of time on the rev limiter - what's up with that ?

That is one nice ride, I noticed the shifter vibrating quite a bit in some places like the final straightaway. Is that from hitting the rev limiter?

Yes, if you listen you can hear the rev's banging against the rev limiter (identical to the red-lined rally cars just prior to releasing on the stage)

Kinda odd that the shifter is shaking so violently during that, though perhaps from rapidly loading and unloading and reloading the gears caused by the rev limiter?

Most of the time, he is letting it hit and not shifting, since shifting up would take him to the braking point anyway, and he would be downshifting for the corner. A few times he leaves it there when he still has plenty of room for more acceleration, which is odd for trying to get a best time. Only other thing I can think of is he didn't want to go faster due to the bumps, trying to keep it under control.

Also, all of those mods into the ACR and no short-shifter? That thing is twice the height of the stock RX-8 shifter.

I understand shifting takes time and what not but rebuilding and engine takes more, especially with 10 cylinders.

R compound tires makes a huge difference and ACR comes with those stock

I'm not concerned with equal comparison, you can say the same for the GTR with all it's fancy technology. The ZR-1 and ACR use brute force to get their record times while the GTR uses technology to get it's times while still being a better all round car. Don't get me wrong if I was shopping for a daily driver and a track car in one the GTR it would be, but if i was shopping for a track car then I would choose the one with the best track times. As for the ACR being hard to handle, that just the fun of it, how boring would it be to just sit there while the car steers itself. If the GTR-V spec bests the ACR then you could then say that the GTR-V spec is the best Daily driver and track car of the three. As it stand now the ACR is the best track car while being the worst daily driver ouch!

Fully adjustable suspension, tunable to a specific track, is a major plus which also comes stock. The aerodynamics are really good on this car which is a must for the Ring and I think I read that engineers have seen like 1.5g's in fast corners. All this for under $100k and a 22mpg rating on the highway. lol

Not surprising this car can do this if not more. When R&T tested all those cars on all the different track types the ACR pretty much dominated all but the Lambo LP560-4 and tall gearing (which I think is an advatage for on the Ring also) of the ACR was blamed for slower times on the smaller, tighter tracks.

The ACR is known to be one of the best handling and most predictable cars out there

that Viper is a MONSTER

it sounds like a beast! probably cuz it is... haha
