I added this link. I found on Ferrari Chat as those guys were talk about it. The Viper ACR is second on the list. Even the ZR1 is 6 steps down on the list. Only car that has the leading times better than the Viper Srt-10 ACR has a open-drivers chassis.................... WOW!!!!

Insane car.. definitely a beast to be respected.

 

Nothing but love for the ACR. Just imagine if they actually developed that car at the Ring Its that they only spent 3 days and 6 laps to destroy the production car record. If they had a gearing suited to the Ring, suspension optimized for the Ring, and clean run without a 25mph head wind this thing would easily be in the 7:1x region. Really phenominal that this was done the old fashion way instead of the usual hightech way.

 

Wikipedia is pretty gay though....so much incorrect info on there.

 

Now I knew there was people out there still not believers. They say the proof is always in the Video. http://www.youtube.com/watch?v=o2mFEC2H0cY

And if you still are questioning I have another video with the ZR1 and the ACR side by side. I dont believe everything I read either but come on!!!!

 

I just have to throw this video up there.

It has a functional wing, rear diffuser running PS2's with CUP compound and improved suspension and brakes over past Vipers plus an 8.4 liter motor. I would be LOL'ing if it didn't set some kind of record.

 

The Radical SR8 shouldn't be considered a production vehicile for road use. Open wheel chasis, no amenities, no doors, etc... It should be classified under something else.

 

It's not just a functional rear wing and front spoiler. Its aerodynamic upgrades produce 1000 lbf (4.4 kN) of down-force at 150 mph (240 km/h), or roughly 10 times the downforce the base Viper SRT-10 can produce at the same speed.
I am LOL'ing ...............

 

By your logic then the Veyron, Zonda, CGT, CCX, Gallardo, Ford GT, GTR etc are garbage cause they didnt break any records even though there technical resume embarasses the Viper and exposes it as a comparative dinosaur.

For all there respective exorbitant hp levels, ultra hightech powerplants, gearboxes, suspensions, CC Brakes, carbonfiber monocoque bodies, multimillion dollar R&D programs, racebread tech etc they all lost to a car built with yestertech. CCX has 800hp+, race suspension etc and Veyron 1001hp and an 8 ltr motor yet neither was able to break into the 7:20's let alone get close to the ACR's time. Its painfully obvious that everything you mentioned doesnt guarantee any records. Come on man give the car its due without the backhanded compliment.

 

Heres a pic of my ol' 2 valve per cylinder, low tech 10 banger. It puts a smile on my face every time I see it an drive it.

 

^^Just to be clear my use of "yestertech" and "dinosaur" were not meant as disrespect just as perspective to really illuminate what SRT accomplished with the ACR despite the paltry budget they were saddled with and lack of R&D on the Ring. Viper budget has never been close to being on par with GM, Nissan, Ferrari etc for there respective supercar yet here it is at the top. I agree with Oryx the Radical shouldnt be there.

 

I think that it even more impressive that a supercar dinosuar as the Viper,can set the pace for all those other high tech Supercars. Reminds me of the old Shelby Cobra. I am not that old but I built one from a Kit with a crated 427 motor. And actually carbonfiber monocoque bodies is yestertech. Carbonfiber monocoque made its debut in 1981 with McLaren's MP4/1 Formula One racing car. Over 10 years before the Viper was even made.
And if you ever been behind the build of the Viper as I have modded them. You would be surprised how muti-million dollar hightech engineering went into developing the underrated American Supercar.

 

Love the orange! Looks awesome.

The thing about the ACR that I admire is that no manufacturer has ever created anything so purpose-built. Many of the cars previously mentioned could and should be faster around the Nring but nobody has ever sacrificed acceleration, top speed, gas mileage etc. for the sole benefit of faster lap times. The exotics have used carbon fiber, adjustable suspensions and aero to some extent but not to this degree.

I hope these days aren't over!

 

Apparently I got a little carried away trying to show the specialness of the ACR's effort and have ruffled feathers unintentionally Ive seen the Viper chassis in pics way back in 95 and from the reactions of some serious racers it is a stout, race ready chassis so I concur. Come on it handles 1500hp/1900tq without the absolute need for a roll cage or the chassis bending. I meant that "comparatively" its a low tech means of going stink fast compared to the techno wizards that populate the Ring list.
