Hello All,

I'm heading to the track (Mid Ohio Road Course) in my 3rd gen Charger 392 Scat Pack (2020). The car is mostly stock except for a CAI. I've driven the track previously in my 2nd gen (2012) SRT Charger. My previous track prep for the SRT consisted of:

- Front adjustable control arm (increased camber)
- Front Frozen rotors paired with front Hawk race pads
- Replace stock brake fluid with Dot 5 high temp brake fluid
- Nitto High Performance Tires (can't remember specific size & model)
- Synthetic oil change

With that track setup, my 2012 SRT performed exceptionally well at Mid Ohio. The brakes never once faded even with exceptionally hard driving. The coolant temp ran hot but would quickly cool off between sessions. The only issue I had was that I blew the Power Steering pump on the last session of the day. I've read that the 3rd gen LX's changed to electric power steering so the issue with the pumps doesn't exist anymore. Is that correct?

I've also read that it's recommended to remove the under-engine panels to provide more engine compartment cooling. That sounds like a good idea and I'll probably do that.

Any other thoughts or suggestions?

It says this in the Challenger OM and I assume this meant belly pans but some say no. Don't know what else it could mean. Does removing your grille really help? Seems to make no sense.

DOT 5 brake fluid!? That's the silicone stuff which is incompatible with other brake fluids. DOT 4 fluid with a dry boiling point over 600 is the norm - Catrol SRF, Motul, Wilwood, ATE, et cetera.

Running with an HPDE group or TNiA? Other than watching for brake fade, your 2020 will have the fancy digital dash & pages to monitor all the important gauges - coolant temp, oil temp & psi, trans temp.

I read the lower tier Mopars have all electric steering but some higher end ones retain electro-hydraulic systems (I may be wrong as I haven't paid too much attention to the LD/LA platforms). If it would blow again at least you know you can easily plumb in a larger heat sink cooler tube like from the Frankencooler thread to help things out.

All the 392 cars have electric power steering. The Hellcats used the hydraulic, but think I remember reading something about the current ones having swapped to electric too. Slidd can confirm.

My suggestion is to run the car bone stock. Then you'll have a baseline for future modifications. In stock form, the car might surprise you.

Yes true, from 15-up, all 392 cars will have electric power assist.

In 18 and 19, Challengers Hellcats got it but it did not come to the Charger Hellcat until 20.

Removing the lower grill did make a tangible improvement on my oil temps. I also had this recommendation confirmed by Jim Wilder as being helpful.

Recommend changing pads and fluid before running on track...my stock pads went from 7mm to backing plate in ~30 mins. Powerstop "Trackday" pads were pretty good starting out. Motul/Castrol/Brembo/Endless fluid is ideal IMO. I've run 7 events with my car this year and the brakes are the biggest issue...even running Carbotechs now.

You have a Challenger? What year?
