interesting to see all these 1 2 mile vipers with aero

[SRT_BluByU]

I always thought the base SRTs would make ideal top speed machines. light weight/low drag. But i keep seeing these TT super hp speed machines with ta aero, acr-e aero etc.. what happened to taping all the seams and making the car as slippery as possible.. ?

Speeds requiring downforce to prevent take off happened

And apparently still take-off isn’t far away...150CCA34-7FED-463B-80E8-72CF81E1559A.jpg

Big power cars need traction, and that is what the aero provides.

ACR-E doesnt make sense to me for a TT 1/2 build.

The obvious problem is that the OEM ACR down force has to be rebalanced. The front does not have enough down force which is dangerous and also slows the car as the drag coefficent goes up.

Totally agree... ACR/E aero designed for speeds below 170mph. The car isn’t squatting that much from acceleration at 150plus, its squatting due to extremely imbalanced aero at 200mph+. It’s amazing that the rear wing isn’t ripped completely off of there considering the forces a 1200whp ACR hits in the mile. LOL.

[SRT_BluByU]

Even the SRT's produce downforce if im not mistaken all the way up to the factory top speed of 208... these 1/2 mile 1000+ hp cars mostly seem to be sub-200mph in the 1/2. would think the lack (or minimization) for drag from the SRTs would be ideal.

Is this from a launch squat or is this car trying to lift off to the moon during a high speed run.

It's Dodge's new SpaceX program.

I also believe that the aero works great through the mid 150-170s, but hinder a top speed run.... Basic physics. A better solution, if speed was the only factor, would be a smaller, adjustable wing. Problem is that when someone buys a 175k car and then adds another 100-150k, they wanna look good! Pretty sure they use this car for the coolness factor. Would be intersting, and the question has beenn asked in one of his vids, if he tried a few runs with just taking it off. There is a vid of one in a quarter mile track doing just that. I believe he had great results.
Some def baddass machines tho! Their coin, let them play! I shall live vicariously through them and youtube! Lol

Best solution. Aftermarket active ACR wing uprights that reduce the downforce as the speed increases. Still looks good and will kill it in the 1/2 mile and road course.

Everything here is correct, even with the minimal aero of the ta 1.0 it drops it under 200 mph stock. learn from the top speed king bugatti, in its top speed mode the car lowers, retracts the rear ring, and closes all the cars diffuser flaps.

Eh...you don't really need much aero. Just the proper setup if you are pushing big power. Look at Sal's car. He ran 237 in the 1/2 mile. I think he has a T/A spoiler and a splitter but that's it. he is on 15's though in the back.

[racegate]

1/2 mi racing is not "top speed" racing for cars with this much power. It's actually an acceleration contest to see how fast you can get to in a fixed distance. That said, the aero does help with traction down low and then trades it off up top, in the 1/2 mi. As it stands, the ACR-E has too much downforce for most speeds, and could absolutely stand to have less rear downforce for something like this.... I think an ACR-E with an Aeromotions style wing would be badass.

That said, I think starting from a non-aero Viper, reinforcing the decklid/trunk, adding an Aeromotions wing with TA1.0 or TA2.0 front splitters to balance it out would also be a killer setup for even straight-line acceleration contests. At a significant discount to an ACR-E as well.

Cool stuff.

[SSGNRDZ_28]

For an ACR E I would start with wheel / hood vents removed and wing in position 1. Wonder if it would be possible to put the wing at a negative angle of attack with some adapter or mod. If so you could probably find a decent balance.

[SRT_BluByU]

not sure aero does anything for traction.. almost zero effect under 60mph.. i think the stock viper body has negative lift at least to 208mph so not needed top end either. if ya look at the salt flat guys its all streamlining and taped seams.. wish i had the coin to test my theory.. would sure like to see one of these nth moto beast run minus all the add on aero and tapped seams vs. acr-e full aero.. bet the moh difference would be big
