Here is what I posted on the challenger forum. I talked to all parties involved to gather the factual information. No nitrous. Tires and racing fuel which we know the racing fuel is essentially a moot point. The car is what it is. I own one. It is bad ***. Anyways:
Burns Motors is the dealer that provided the cars. They were both sold cars that the owners graciously allowed them to use to put this all together.
The driver is actually normally runs a blown 67 Camaro with solid experience. Supposedly is at the track every weekend running his car in the 8's.
RGB Lighting in McAllen TX does lighting and street car mods. They worked with the car and the driver.
The only modifications to the car were in fact drag radials and race fuel. In fact, BOTH cars had race fuel. So the 11.05 run was done with race fuel too.
The tires were the Nitto 555r's, here's the kicker: they were the factory size!! 275/40/20
Several tire pressures were tried. The optimal pressure was 17 lbs.
Third pass on the black car resulted in the attached pic.
Track was heavily prepped and a bit warmer temps on day two resulted in super track conditions. The guy said the track wanted to pull his shoes off.
It was originally reported that you had to roll it out some before you mash it but after talking to the driver he said the best runs came when you were in fact able to mash the gas right at the green light. Period!.
An important thing to note also is that he said they did not start getting good times / hookups until they turned the stability control completely off. He said once they got that off (which required them to hold the button for 8 seconds), then they started getting good runs. So the car was in track mode and stability control was turned completely off and this was a require,ent to get the car to start hooking up properly.
Driver confirmed that he put the car in track mode and turned stability control off. No other changes to suspension.
Launched as close as possible stalling it to 2000 rpm. Launch control NOT used.
Lastly, the driver used the paddles to get the best times out of it!! His shift rpm was 6200 RPM when he hit the paddle.
That's it!!
Tires and race fuel!!
Vids coming. They have to wait for a few things to happen before they can release them but they are coming.

They did that to the drive shaft on stock power?
That is pathetic. That is what happens when you put a big motor into car and don't upgrade the remaining parts of the cheap base car to accept that power.
The motor is fantastic, too bad the cars they are going suck and are heavy as whales. Rather have it as a crate motor and put it in a proper car.

To be fair, the replacement driveshaft has not failed with several hard runs on it, nor did the driveshaft on the other Hellcat. So it's more likely that the driveshaft that failed was bad from the factory. Time will tell for sure.

As an owner of various high performance machines, I can tell you that no matter how strong you make it, high power always will break something, it is just a matter of time.
Cars, bikes, it does not matter, power will always find the weakest link at some point, some sooner than others.
I have broke many transmissions, half shafts, engines etc... It is the price you pay with high power.
Below was my most recent failure on a "bullet proof" build , while testing launching my 500+ hp turbo busa , I snapped the axle nut right off my swingarm.
The swingarm is a Mcintosh Pro aluminum arm, which is the strongest arm money can buy, this happened on my 6th test launch on the brand new arm, it only had dyno time on it.
Terry Mcintosh ended up making me a custom axle with a thicker inside diameter, but I know if that doesn't break something else will , on hard launches
Just goes to show the these things happen on anything high powered

You are correct, I didn't consider the oxygenated race fuels available..... if the conditions you cite do exist then it would most certainly be helpful in achieving some additional power.... still not another 7mph I'm afraid. Hence my earlier statement that I believe it's a factor of many different things being perfect weather, a strong running car, great track prep and possibility of running race gas such as MS109 and the car being able to take advantage of it. 10.48@133mph is definitely a huge accomplishment with what would be considered a stock car on a tire..... hence the reason I'm looking to see some additional information here as it's not a typical result.

Maybe the C7 Z06 is a great car with a lousy engine by your goofy logic.
And the Hellcat is overachieving at this point not under achieving like some "Other car"

The latter had drag radials, the other didnt. Trap Speed at the 1/8 for the drag tired car was high as well.

here are a few other vehicles' common driveline issues:
5 speed WRX's will destroy a gearbox on stock power/tires
f-body LS1 cars will destroy a rear diff on stock power/tires
EVO's will destroy a center diff on stock power/tires
Z3's will rip the rear diff out of the car
early GTR gearbox's did well
Lambo/Ferrari clutches
C5/C6 clutch issues without constantl bleeding

I understand although the 10.4 car trapped 106 in the 1/8 and the street tire car trapped 100 I believe even though it cut a solid 60' that's a huge jump in MPH by the 1/8. 2mph maybe 6 seems pretty crazy.

A lot of you folks are going to be pretty shocked at how fast that fat kitty is going to be in a drag race, with good sticky drag radials or a full drag slick. 10.5s on a good prepped track and good air is going to happen for the Hellcat A8
and she will rip-off 10.7s all day long (and then I am going to have to have one as my daily driver, replacing my 2008 First Edition Challenger SRt8).

those are great drag cars, how do they do on a road course I wonder? 
Challenger boys the ONLY thing the fatcat has going for it is a straight line speed, how does it corner and brake, you know, the other elements of racing? Let me know when you come up with an answer, I'll be here waiting.
When a base C7 with 152 less hp can beat it around any road coarse, that says something........
