Latest teaser video...
2538 PSI has got to be max cylinder pressure ...
Demon at 808hp was 1958. So 2538/1958 = 1.2962
1.2962 x 808 = 1047HP (HP bump won't be linear...added this to show it's def significantly more than Demon)
Interesting note on the Demon's max cylinder pressure below....the SRT engineers could have easily eclipsed 840hp but didn't since it went past their design tolerances. So by beefing up max cylinder pressure capability Dodge can now aggressively advance timing a lot more than 5 degrees with the E85 tune....interesting!
Maybe...This was how they were grenading engines early on. Just advanced timing with E85 without sufficiently beefing up cylinder pressure capability? Tim said it would be "funny" to talk about it later...Maybe this is it?
PS 135 Bar= 1958 PSI

Fuel and 100-Octane Systems (Demon)
To feed the massive horsepower the Demon is capable of creating, the fuel system needed a boost. Twin, in-tank pumps feed injectors similarly sized to the Hellcat, but with an increase in overall fuel system pressure. The 100-octane mode, included with the $1 Demon Crate, allows the car to increase peak power when activated. The system needs a minimum of 100 average octane in the tank and will actively disable the mode if it detects knock. The real advantage in power and torque in this calibration is the ability to add spark advance due to the higher-octane fuel's resistance to detonation. At peak torque in 100-octane mode, the spark is advanced 8 degrees for a 53lb-ft bump. At peak power, spark is advanced only 5 degrees for an additional 32 horsepower. Engineers were quick to point out that additional ignition timing at peak power did further amp up power production, however it eclipsed the parameters of their design window. Chris Cowland, head of Advanced and SRT Powertrain, explained that the engine is design for a max cylinder pressure of 135Bar and increased ignition timing eclipsed that threshold.
