2019 HELLCAT RED EYE
#1
I took a journey to get to this point. During the summer I had a 2.85 upper, 180 degree thermostat, catless mids installed. I also had suspension links installed so my 17" rims would fit. To be honest, I was pretty bummed out with a rating of 714 rwhp on the Mustang dyno. This was from a baseline dyno of 616 rwhp. I think they called the dyno a 'heart breaker'. I received the tune and the work was done by Peitz Performance near Katy, Texas.

I took the car and made some passes as is at Lone Star MOPAR Fest in early October when the DA was around +2,000. It was a hot and miserable day at Houston Raceway Park. My best time that day was 10.424 @ 133.94 and considering I had a 2.85 pulley I expected a lot better time.

I had been thinking about getting a set of Demon springs, but don't have the tools or knowledge to install them. Luckily I have a buddy who is a mechanic so I bought the Demon springs and had them installed.

I was invited to a track rental at Houston Raceway Park on November 3 and looking at the weather reports, it appeared we would have real good weather. When I arrived I was first in line and the guys there were doing an outstanding job of prepping the track. I have full seats and full weight and the only prep I do was putting the Mickey R's (305/45/17) at 18 psi.

Since on only prior runs had a PB of 10.424 my goal was to get into the real low 10's, maybe in the 10.teens or even 10.zeros. I figured that only in a dream would I get into the high 9's.

So the track was ready and I lined 'em up. My Mickey's made a nice smoke show. As the green light went on, I revved up the car then launched hard. No spin, no nothing, but haul ass down the 1320 feet.

I knew I had made a great pass, but I didn't know what the time slip said as the time slips were at the starting line. Since I was the only one running, I made another immediate pass and this one felt the same as the first one. Pure hard launch, no spinning, no wheel hop. I did notice I was going into 5 th gear real near the end of the quarter mile, maybe about 50 feet from the end the car shifted.

I parked my car and walked over to the clip board and got both time slips, and there it was, the glorious 9.991 @ 136.95. I was literally blown away with the 60 foot times of 1.453 and 1.454 on the runs. There is no doubt in my mind that the Demon springs allowed my car a lot better launch than before I had them installed.

The question is this..........Do I have a 9 second car? Yes I do, however it took negative DA to get the time slip. As the day warmed up and the weather got hotter, I made a 10.07 and a 10.16 pass, which shows how much of a difference DA makes. Was my 9 second pass a 'hero' pass.........NO, because I was immediately backed up with a 10.02 and a 10.07 pass. Had I made the 9.991 pass followed up with 10.2 or 10.3 passes, then I would say I made a 'hero' pass.

Congrats!

DA makes a huge difference. I normally only make passes in the spring and fall.

As far as dyno numbers go, it may be cool to have a number but being everyone is different I don't get to caught up in them. As long as you hook at the track, those are the real numbers of how much power your car has. One of my old cars ran faster then others that said they made 150 more hp on the dyno then mine did

I made a copy of it and laminated it so I can carry it in the car, just in case someone talks trash to me, I'll just pull out the slip.

Great job! Congrats on the 9 second run.

I've personally been quite surprised(and truthfully disappointed) at just how air sensitive these things are. I have a considerable amount of blown motor experience in all sorts of weather and have never seen anything as air dependent as these cars.
Ah well, they're still a blast even in the sticky slow weather.

Did you have any runs before the 100hp increase?

If the prep was great, you could have experimented with raising the pressure in the tires, that may have put those 10.0s into the 9s as well.

Nothing was said. Had it been a test and tune night, no doubt I would've gotten my hand slapped, however since it was a rental, nobody said anything.

Then again they may not have cared given it was such a high 9. Had it been a 9.7 they may have said something. I really don't know.

My goal is to have a test and tune night with -1000 DA make a couple of 9 second passes and get tossed. :LOL:

Dynos are BS and should only be used to nail down the tune

4400lbs (assumption) at 137mph is 870whp!!!!

You have a 9 second car. Look what Dodge did to get the Demon's record. Congrats

Congrats on the 9 second pass !
Alex is a good tuner & the Mustang dyno is a heart breaker to those that are expecting a large # but it's more real world. The only # that matters tho is the track ET's.
Alex also tuned my HC.

What was the DA on Nov. 3rd ?

The DA was -325 when the first pass was made, then quickly moved to the positives as the day wore on.
