2015 Challenger Hellcat 707 HP

[HEMI DAVE]

Here is the 133.5 MPH Hellcat run.

Yeah...no indications of nitrous for that run.

Unless they were running nitrous from the initial hit, during the run I didn't hear any surge of rpms that would be expected with even a small nitrous hit. This car launched beautifully and went full power almost instantly, amazing given that the DRs were only 275 series Nitto 555rs which most consider only a small step up from a street tire. The track prep must have been superb.

Yeah, 275 Drag Radials are taxed to their MAX by the Hellcat. That run is probably a "World Record for 275 Drag Radials", right? Right!

What does that have to do with anything?

He was simply commenting that the run was done on NT555's and that better DR's are available.

So does anyone know what the max width street tire that will fit on the hellcat challenger yet?

Absolute max? I think I saw 310's were the absolute widest. 315's will rub.

305's fit no problem

Do you race? Have you ever raced? Do you have any experience with 555rs? I do with both my Cobra and SS and I can tell you I never was able to make them work. In my experience the NT05r or M/T were worth at least a tenth in the 60'. I am sure many others in this forum who drag race with DRs will agree. I suspect they may be using the 555r to prevent drivetrain damage offered by a dead hook from a slick like DR

That's good to know, I would be scared driving this beast around on 275's. I really want one now lol

NT555's are cheap, widely available and are a "low shock" tire...not surprised they were using them at all.

The new MT "Super DR's" that debuted at SEMA are going to be spectacular tires...I cannot wait.

Another angle...........

This thread just will not die.

The Hellcat is an awesome car. Love it or hate it, it is.

Let's turn off the lights and go home gentlemen.............

Im pretty sure he was implying that the NT555Rs aren't the best choices for a DR. I have had experience with them and no matter what I did, what track I went to they were just about useless for me. They were a great STREET tire, but useless as a track tire.

My experience with DRs isn't huge, but M/T are the best I have ever used.

So someone talks directly with the source and confirms that both cars were running 109. Now, a week later, the track manager says it was 93? This story get's more capricious by the minute.



Indeed. But when Dodge does it they deserve "special attention".



Get your facts straight. The Hellcat has been tested and reviewed since July. Deliveries started late October/early November. Cars.com had one at the dragstrip in August and ran 11.4.



I didn't realize Dodge delivered Hellcats with 109 octane. My mistake.



Any number of cars are this fast for far less. What you're trying to ask is "what other $60k cars come from the factory with a full warranty and run 11's stock"? The C7 comes to mind. But, but, but I have to accommodate three midgets in the backseat they will say. Not to mention, Ford already built, sold and discontinued a car that did this. Nice of Dodge to mimic.



Nope. I'm not "hug" up on anything. I fully expect some Hellcats somewhere will match and exceed Dodge's 11.2 claim on street tires. Look at stock ZL1 times - far faster than what Chevy marketing announced.



Those journalists, flawed as they are, also tested the GT500 and ZL1 in the same manner. Relative to each other those results are very consistent with actual owner times as I have shown time and again in this thread. Sure some will run slightly faster...but many will run considerably slower too.



Nowhere did I say or imply that stock times should be discredited. I think all times should be considered when evaluating the performance of a car. How can you recognize the 11.4 cars.com ran but not accept the 12.11 this guy ran?

Funny how Mopar fans flock to this forum to post a postive magazine time/review but when I post them, they're no longer meaningful? You have a better way of providing head-to-head performance metrics and driving characteristics than from people who do this for a living? No, MotorTrend, Car&Driver, Road&Track aren't perfect, but their testing methodologies are consistent. All cars will post faster acceleration times than magazines report, not just Dodge.



Really? I've owned two Chevy's in my entire life and one Cadillac. I've owned far more Chrysler products than GM. Nice try though.

I just joined in on this party. And OMG, ^^^^ this guy is butthurt butthurt butthurt...

Yikes!
