Now you have an extra pan in case you bottom out on a big wheelie! Does it have a Hellcat logo on the bottom?

Is it SHR telling you about the failures or other people in the industry? Would be interesting to hear their stories.

Lots of self neutering HC and Demon owners - I like to call them "investment grade" owners. But, yes - it appears that the car will adapt to you and how you use it.
Well , I baby mine on the street , until I get to the track.
I wonder how long it takes it to go from "wuss" mode to "raped ape" mode ?.... once I'm racing at the track.

TO REPLICATE THAT P4 PLANATARY WITH A STRONGER ONE I WOULD THINK THE COST WOULD BE A BIG FACTOR IT ISNT JUST THE OUT PUT SHAFT LIKE A GM OR FORD

If you see how consistent they are, I would be curious to know. Yay, more hell to the P-Zeros!--- Thanks!
2016 HC, Demon, and Trackhawk are all identical.

Not many break these days. Guys either upgrade in prep for a build, had a bad tune, and or drove it in the wrong setting on kill.

I think there is more to it than that. From what I've been told is that the clutches can be adjusted. I assume with pressures to control things.

Not sure if I read you right. No spray with stock blower and pullies on stock motor? If so, that would be my previous car. 9.89 and 142 mph.
