I want to see a 2010 ACR go against a GEN V car on the drag strip and see a head to head test with two novice drives.
2010 ACR vs GEN V car

I would say the GEN V wins hands down. WIth the advantage of launch control it would (in theory) get off the line a little bit cleaner.

ACR on the drag strip? You realize a stock regular Viper will beat an equivalent model year stock ACR (slightly) in the 1/4 mile, right?

This. ACR is the slowest Gen 4 in a straight line, due to the aero drag. It just looks the meanest. Gen 5 is geared much better for 1/4-mile.
And, I'd rather not watch two novices try racing. I'd rather see two good drivers go at it.

I dunno...I think it would be kinda funny to watch if they both stalled at the line.

Gen V with the revised gearing.............no question on that one.
Also, a newbie could utilize the launch control in the new car.
..............and yes, the ACR is only faster on a road course.

Or staged with the rear tires.

I guess mine would fall in the middle , since it is not a ACR but has Aero package (smaller rear wing and no front side wings).
I have yet to be impressed with the Gen V dyno sheets 1/4 times or MPH.
IMO stock for stock pit a GEN IV and GEN V against each other and it would be a drivers race.
Until I start seeing several 10 sec slips and high 120s out of stock GEN Vs starting to think the GEN IV was severely underrated.
Sure the V has everything going for it.. "640/600" 3.55s, aluminum flywheel, launch control, revised intake, exhaust, carbon fiber etc.
I was a believer the V would be a 10 sec 129/130 mph car all day long, but haven't seen it yet..

It is slowest at the top end, drag really starts affecting the car above 150 mph, this is why downforce for ACR is given at 150 mph. On the track, you will not come close to speeds where you notice the difference.

No contest the Gen V will win. I start feeling aero drag around 80 mph in my ACR, the down force starts working way before 150 mph.

I think it is still a drivers race. Theoretically a Gen 5 should be a couple 10ths quicker, but with a good launch I think a Gen 4 might win.
Do not bet on anything, Gen 5 made some improvements on tire related lift but downforce generation still belongs to ACR, unless you equip Gen 5 with similar set up. Just because drag and downforce are there, this does not mean they are the dominant factors since there is body and tire lift to consider.
How did you come up with these numbers? At 150, ACR generates about ten times as much downforce as base car, where are the numbers for the lower speeds coming from? Are we talking about NET downforce after subtracting the lift?
I came up with those numbers that at around ~65mph the ACR is producing ~200 pounds of downforce, and the numbers I have seen in the past is the coupe produces ~100 pounds.
@~120mph the ACR is producing anywhere from ~600 to ~700 pounds of downforce depending on the position of the rear wing.

Aerodynamics start coming into play as low as 40mph, this is why manufacturers work on improving the Cd on everyday road cars as well.

The numbers I see mention base car producing 100 at 150 actually.
Where is this graph from? This graph looks very misleading, is it from a Chrysler sales brochure?
That was my point, at 65mph the ACR is producing 2x the downforce as the coupe at speed.

Anyone have a stock Gen 4 in Houston? I have a stock Gen 5 and am willing to participate.

Drag strip? Gen V by far over 2010 ACR. 40 more ponies on the Gen V and no aero wing on the back.

Attribution is Chrysler, but likely from SRT group themselves. Why would you say it looks misleading? Most car designs produce lift at speed unless they have a lot of aero tweaks.
What matters is the difference between the downforce and liftforce, I hate to see Chrysler claiming numbers based on "typical sports car" lift being used to make any claims. Is this another graph from a sales brochure? I hope you realize how meaningless this graph really is...
The graph came from here. Please explain how meaningless the graph is?

I get very suspicious when "typical" values are used for comparisons. I am not trying to start any argument so I am going to bail out. Sorry for any disruption, I think it is better if I just keep building my own stuff instead of arguing about designs of others
Bump because I'm curious if there's really much difference at all.

Comparison to what? Both graphs were used in this thread to serve the purpose of showing the downforce of the ACR in relation to speed. Ignore the bottom yellow line if it bothers you so much.
