There is a Local guy who got a very early hellcat challenger when they came out. It seems he got the benchmark one from chrysler because it ran exactly how they said, 11.30s stock tires and 10.80s on slicks. I saw it run something like 2 or 3 10.88s in a row when it was stock. Pretty impressive especially for something with forced induction.

I have a '16 scat pack challenger... it is absolutely amazing. I drive it year round... through the Michigan winters and all (with snow tires).
My little brother ran it last summer and it went 12.01@115mph in the dead middle of the muggy summer on a set of drag radials, so I'm sure in decent weather it's run well into the 11's without issue.
If you're looking for something you can cruise, enjoy, and click off some fun numbers... it's really hard to beat.
That being said... it is a REALLY SH*TTY bracket car. I ran it at monster mopar last year, and an NMCA race. The fly by wire throttle makes it nearly impossible to leave off the bottom bulb, and the consistency from pass to pass because of all the electronics leaves a lot to be desired. The 1320 might be a bit better because of the trans brake on the reaction times, but it's got the same motor as my car, so I can't see it being any more consistent.
I had the exact same thoughts of selling my turbo car, and buying a hellcat to dual purpose... but after making ~75 runs in my scat pack last year there is no way I can see one of these cars competitively bracket racing and going rounds in any sort of serious competition.
But again... if you're just looking for fun, the car is incredible. Comfortable, sounds good, goes good, stops good, turns good... can't deny that.

I did the same thing year and a half ago, 2016 M-6 Hellcat. Fast, comfortable, kick-ass stereo, and my girlfriend can even drive it. Still have my tube chassis door car, Also bought a dragster over the winter, not gonna race much longer, but want to maybe make some 6 second passes before I hang it up. My son will prolly end up with the race cars. That being said, the HC is the most fun-per-dollar I’ve had yet. Jim.

[/quote] Get a pedal commander, it will fix that issue in 2 seconds. https://www.youtube.com/watch?v=En8K76-C7sE [/quote] The pedal commander simply changes the sensitivity rate of the throttle. Basically tells the PCM you're at 100% throttle when you've only travelled 50% with your foot. This is no different then what you can do with any tuner bumping the throttle % up. But the problem is not there, it's in the PCM itself. The PCM has quite a few safety and drivability delays built into it. These are NOT parameters that a regular tuner has access too, only an FCA development PCM unit can take these changes. But even at that... the cars still aren't good enough to foot brake off the bottom bulb unless you're guessing in between lights (or going in way deep).

I've got about 80 passes and a few races on my 1320 since buying it late in 2021. All of the following comments are "YMMV"... - Mine has the full upgraded interior and I weigh 200+; I don't recall exactly what it scaled last year, but definitely over 4300 - I'd say mine is basically a 12.0 car that has dipped into the 11.8s under really good conditions... or slowed down into the 12.2s-12.3s when the atmospheric conditions swing to the hot & humid side - I see where some people post how their "stock" 1320s are busting mid-11s, but also know of folks who have never seen an ET slip faster than 12.x with theirs - My original expectation was that it would be really consistent since it's "all electronics"... but it will do stuff like mysteriously slow down a tenth & 1 MPH for no apparent reason between passes - I'd say the grains of water in the air is a big -- possibly the biggest -- predictor or performance with my car, even more so than the basic DA measurements; I've watched the DA fall significantly without any performance improvement because the humidity & water grains went up as the DA fell - Heat soak hurts the car's consistency, too; I only started putting ice bags on the intake between passes the last time I raced in 2022, although I'm not even sure it helped - Can't say if it's the car or the driver or both, but some days I've put together a string of decent .0x lights, and other events I swear I'm doing the same thing and can't get under .1x. FWIW, I don't deep stage. On a .500 pro tree, the best RTs I could get were in the .26-.30 range - Factory-size 275/40R20 drag radials are totally hit and miss; they'll dead-hook or they'll spin & hop cuz the short sidewalls are unforgiving of less-than-ideal track prep; I made the decision to stop using the 20" setup at the track because it's simply too unpredictable - You'll see it's pretty common for Scat Packs in general, and 1320s in particular, to be using either 18" or 17" rear wheel setups to get a bigger selection of tires with taller sidewalls for more consistent launches; I have alternate wheels with either 305/40R18 or 305/45R18 drag radials to use, instead - Only a very small percentage of 1320 owners use the trans brake feature cuz the cars seem just as quick off the foot brake and the trans brake procedure is awkward to follow; I never bothered testing it after the general consensus is it's more of a gimmick than a benefit
I still love the car, but IMO it's not an effective bracket racer as delivered. I haven't gone back to the track since the last event I ran in fall 2022. Figured if I wanted to be serious about going rounds that I need to pull my head outta my a$$ and get the '73 back on the road & track, since it's still a legit street/strip car that gets driven to the track.

I bought my 2020 T/A 392 & was going to sell my 68 Charger street strip car but I ended up keeping it, I LOVE the new Challenger, with drag radials 390/40/17 M&H it dead hooked every time 4 passes, had a 14 mph head wind, 1st pass was 11.79 @ 115 was the best, heat soke slowed it down by a tenth, no oil catch can but I deleted the PCV valve system & have two moroso breathers to atmosphere one on each valve cover, other than that it is stock, according to Wallace calculations it would have run about 2 tenths & 2 mph faster without the head wind, I am not so sure about that LOL, did I say I love my new challenger ???? just remembered I did set the REAR camber to 0 so it would plant the tire better, stock it was neg 1.7 in the rear. car is 4445 LBS with me in it.
