Hey Guys,

So my modified 2.80 Griptec pulley, catless mids, ID 1050 Injectors, JLT Intake and tunefor race gas by team hellcat kitty made 803 RWHP on a dynojet through a 6 speed manual.

Because I am not ready for drag racing due to stock driveshaft and clutch, i have been testing using 60 - 130 on the racelogic V-box. Here is what I have found

First Run : 76 degrees
2nd - 4th gear = 7.2 sec

Second Run : 71 degrees
2nd - 3rd gear @ 6700 rpm = 6.8 sec

Third Run : 65 degrees
2nd - 3rd gear @ 6700 rpm = 6.3 sec

Forth Run : 72 degrees
2nd - 3rd gear = 6.6 sec

I have attached images below but here is what I learned so far.
- start at 45 mph
- take each gear to almost redline (mine is 6900 with tune)
- make sure your IATs are cool as possible
- try to be on a flat non sloped surface

My Future Goals :
- try again on a 50 degree day with negative Air density for a 6.1 sec time
- add smaller 2.75 pulley, heat exchanger, short shifter, upgraded clutch, retune for 860+ rwhp = 5.8 sec or lower time

Looks like you were figuring it out. That is a very stout time you are running. Low 6 second is beating lots of supercars and sports cars. Once you get into the high 5’s you are now running against sport bikes and stomping most everything. Low 5’s and you are darn near untouchable unless whatever your running is highly modified.

Keep it up man.

I would also think your shift is slowing you by at least .2-.4 seconds as the A8 just shifts faster.

What’s your 0 to 100 on the street? Are u in the 6s or low 7s?

I had some great conditions in a Redeye early last Monday morning, DA was about 1500'. I looked at a few laps for 60-130 mph. Best a stock RE is about 9.7 sec! I had to do some math, because the only spot I can get a 60-130 is between laps, but I think I did it right, I looked at about six combos. Lots of high nines.

You are flying!

Maybe I have a slow one. I sampled several laps on a road course. For the hell of it, I just timed it manually watching the video. Get upper nines. Looked at the old Hellcat videos also just to check, manual timed one lap at nine and another at 9.5 seconds. Same two cars blow away about every Corvette and any other car up this straight. You are flying!

Maybe because I am easing into it at the 60mph coming out of a corner, we have the couple second problem?? It is not a WOT at 60, it takes a few to get it open and confident we are not going to turn it to spinning gunk as we need to go over the starting line at BIR and up the straight.

Yeah I think it’s something like that. It’s hard to judge it based of a video and just trying to time it.

Make a clean it with a recording device and check it. I would say high 7’s for sure.

9seconds think about 1/4 mile times. If you high 9’s from 60-130 then just add the 0-60 from the hit and you got a 1/4 mile time.

Your a solid 11 to high 10 second car. So do the math.

What are you guys using to get this data?

0-130 basically. 11.7 seconds. Stock HC Charger just wheels 10.5 all around and Wider Michelin ps4s. None prepped, flat street surface about 88 degrees outside. We are at about 300 feet above sea level in bucks county. And 0-100 one of my best on the street.. 7.5.. I do a little one second and a half roll out before I get into it. That’s my little trick.. no pre burnout (this time hehe).. tires at 34 psi warmed up. Also I always shift the car Manually in M mode with shifters. 1st gear I usually click off around 4000rpm.. then blast 2nd once you hit 18-24 mph. This may sound silly to some but I can get faster more controlled consistent times this way. In the 0-100 dept.

That’s real good times for stock trim on the street.

I bet you make some people look pretty stupid trying to roll race you from 60 whipcat lol. Hell you could be like hey man I’ll give you a 3 second head start. Your gonna need it hah

Lmao. Wow you toyed that guy. I had to go back to catch you were doing 123 to his 141 or something. The camera pans back when your done the 2nd half the stretch. You went from 123 to 183. In the top end. Impressive. What gears are you running whip? .262 or .309? I assume the .262 with all that power doing the mile..
During the video I was running 3.09 gears. I’m running the 2.62 now.

It’s funny I never noticed the other speeds I didn’t know that was us, it was probably our 1/4 mile trap or something. I thought it was the cars that went before us.

Traction is always so hard to achieve.

The other thing in the video is technically we were supposed to start from a 40 roll and then punch it at the cones. I did that and started at 40, the lambo left early and still got smoked.

very impressive!
Thanks bud. It’s a fun car.

Here's my most recent. Car definitely has more in it. It was in good DA but with some serious negative DA and a dead hook I'm sure I could shave a cpl tenths.
