- 2017 Charger HC (once upon a time)
We had our first cool front of fall last night. So yesterday was 96, today was 62. As I"ve said before, the HC sure reacts well to lower IAT. By the rule of thumb, that should equate to about 3.4% more HP and it's quite noticeable even seat of pants. Car much more eager. Comparing the day before to today, same location, I saw about two tenths better 0-60 times.
After work, headed out to my "spot" and by the route I took there is an absolutely 90 turn (no sweep, no jog, no shoulder, actual 90 bend road ends). So I hit this w as much speed as usual and then the road goes straight about 100 or 150 feet or so and begins to sweep to the right as an on ramp. The gentle sweep quickly adopts negative banking as it is joining up with a highway sweeping left turn. This makes for all kinds of fun since you're at negative bank and accelerating with the lateral Gs building into that bank. Always been fun but today something different happened. I'll tell you what it felt like: as the car is tilting negative and we are at WOT later Gs mount and then, in a mere instant it felt like the left rear rubber rolled under and then hops up and jumps about 8" to 1' to the left, I compensated but I'm sure the electronics helped too (not nearly the reactions now I'm sure as when I was a youngster). Never got out of it completely and if this had been a Mustang might have spun the car out. MPH was mid 90s to 100. Obviously the 555R isn't designed for the lateral G force but they've always held up pasably and they did a good job this time too, comparatively. Will I push at that location again? Probably (I like to experiment and investigate) but I'll be more cognizant of the signs the car is reaching the lateral G limit. Of course, out here in west texas it could have been a dirt clod interrupting contact for a split second too (however, I saw no evidence of this; but the clod can be compacted into the aggregate grooves out here and very hard to spot visually). Writing about makes the process seem slow, but it was not. A second or so is all it took; can't reason your way through it. Had I been someone who bought the car and came in with little or no high performance vehicle experience could have had a worse outcome.
Also, this coming week should be mounting the 305 MT ET Street SS on the car. Will try and do same day or back to back comparisons.

It's gone now, but still cold...supposed to stay above freezing tonight, so I might drive the HC to work tomorrow one more time!
