This weekend I will be taking my stock 2015 SRT 392 to a local Dyno day to get a base reading on the car, prior to any mods.
The day will consist of three runs, where I will rotate between Default and Track mode to hopefully confirm the rumors of some power tweaks on the SRT's in Track Mode.
I've seen results of previous stock 392's getting high 430's low 440's, I'm hoping for at least that potentially mid to high 440's with the HP bump this year.
Results will be posted here as soon as I have them!!

RESULTS ADDED BELOW
So, this weekend had me knocked out with a 101 fever all weekend, I forced myself to get out of bed for a few hours later to get down to the Dyno day, pretty sure I infected everyone without a 1 miles radius, and considering the results, maybe I should have stayed in bed.
I arrived with about 4 cars ahead of me, it took close to two hours before I got on the Dyno, so there was certainly no issues with heat soak. The Dyno had been running constantly all day, putting out reliable numbers all day, until the SRT hit the rollers.....
Here are the runs:
Run 1 (Street Mode) - 424hp / 424tq
Run 2 (Sport Mode) - 501hp / 495tq
Run 3 (Track Mode) - 227hp / 240tq
Run 4 (Track Mode) - 270hp / 259tq
Run 5 (Track Mode) - 421hp / 416tq
ALL over the place right? They had to restart the dyno computer after the two 200hp runs, the operator believed the different 'Drive Modes' could have been doing something to pull timing and being on the rollers was confusing the car.....
Here's my analysis on the Runs:
Run 1 (Street Mode) - 424hp / 424tq - Probably pretty accurate run.
Run 2 (Sport Mode) - 501hp / 495tq - Pretty inaccurate, can I explain it? No. Do I like seeing 501hp? YES! ha ha.
Run 3 (Track Mode) - 227hp / 240tq - I wonder if the PCM is pulling timing due to the low miles on the car (800 miles)
Run 4 (Track Mode) - 270hp / 259tq - I wonder if the PCM is pulling timing due to the low miles on the car (800 miles)
Run 5 (Track Mode) - 421hp / 416tq - Probably the most accurate run of the day, adding 15% for drivetrain loss equals 485hp.
I was certainly disappointed with the inconsistent runs, and that nothing to prove any difference between drive modes. Also disappointed that the results don't show an underrated motor from Dodge as many suspect.
Another local shop is having a Dyno Day Jan 3rd, i will be head over there to see what the SRT can put down there!
Let me know your thoughts!
