1/4 Mile Performance Numbers. Looking for insight (Moved To Track Talk)

[Fester]

Hey guys!

SO a bunch of us showed up at new England Dragway last night in NH and we represented the mopar team well! Ari had a perfect rreation time in his SRT8 Jeep!

I was looking to compare numbers with some other guys with similar modes as me (See below).

Fastest I pulled was 14.4 @96mph .600 r/t. That was just slightly faster than gary and a couple others guys with fairly stock setups. I did have a full tank of gas and Gary ran next to empty but another buddy of mine and I were thinking it would have pulled high 13's?

Any thoughts? I have quite a few mods into it so far.

Those #'s are about right on..
Stock RT depending on mother nature and how high above sea lvl you are
Will run about 14.4s all day long.
Friend of mine has borla catback on his RT and ran a 14.3 but he is a good racer.

I went to the track lastnight and this is what i ran.

R/T .134
60" 2.089
330 5.911
1/8 9.021
1/8 MpH 78.56
1000 foot 11.708
1/4 13.966
MpH 99.58

That was my goal with my mods i have done, i kinda wanted to get 100 Mph but im still happy. Also add 180degree thermo to my list of mods

Good job on showing people at the track mopar cars are still doing good!


Also How are you driving your car? are you leaving it in slapstick mode and letting the car shift? or are you racing in D?
And what setup are you using with your SC?

[Fester]

See you have similar mods and you ran under 14 shich is where I though I should have been. I am running the 91 tune with sport tranny. I slapsticked it, power braked on the line and had the trackion contrl off.

What I was saying is mine seemed too close to the stock R/T's for the mods I have. Your's sounds more where I thought it would be.

I don't remember if what tranny setting im running, but when in slapstick mode does your car bounce off the limiter till you shift or does it shift on it's own?
2nd do you have the shift points raised? 6250 i think it is.
If your trannys shifting for you while in slapstick, dont shift it yourself, let it max out and shift for you.
Also your 60 Foot is where your going to drop into the 13.9's, if your not getting atleast a 2.0 60 foot, that means your eather spinning a little bit out of the hole or your not power breaking it hard enough.
my first run lastnight was 14.08, i spun out of the hole and got a 2.1 60 foot.
So i said F it im going to go around the burnout box and warm up my tires and launch my car like i stole it. Thats what got me into the 13.9's
Hope this is not to long and helps a tad.

[Fester]

Interesting. I shifted right around 5600 each shift. in Sport tune or perf tun on the transit will hang till you force it there is no auo shift points when you are in sport or perf

I did not warm up the tires on any run and I only ran the RPM's to 2000/2500 on the line. I know the first gear push is around 3500 where it really starts to pull. Maybe I needed to run 3000 on the line and warm the rubber. Maybe that's all it was hat was keepig me at 2.1/2.2 at 60'

[Absocharged]

Good luck.
Keep us posted on how ya do.

[06chargerDaytona]

i ran 13.9 with intake and chip on a hot day

[Absocharged]

i ran 13.9 with intake and chip on a hot day

And you live where?
And your MPH Was???
And your 60 foot was?

Like i said in my post above, mother nature and sea level have a lot to do with your times when we are talking .1-.3 in the 1/4 mile along with driving skills.

[CHERRY]

Allot of ET is wasted on bad sixty foot times.
Can you post your complete runs for me to see ?
I have been Drag Racing for 34 years and I am willing to offer advice.

[FlyByU]

thats your problem, bad 60 foot times. Work on the launch and you are going to have much better ET's.

You would have probably broken 14's with a decent 60 foot on that first run. Im assuming the second run was even worse because you had an extra 180 lbs because of a passenger.

[Fester]

what advice do you have for better launches? To be honest last night was my first time out ever on the strip.

[FlyByU]

Were you spinning? I imagine so. You have to roll into the throttle, not just floor it. Try stalling it up a bit and when you leave, let it jump off the line a little before you start to push the gas down more. Its really about figuring out what works for your setup. My car has totally changed since I first got it. The converter makes for a totally different feel.

[CRF450RR]

Today my wife ran her bone stock 07 R/T at Infineon Raceway.
Her best time with a co-pilot (me 165 lbs) Air temp was about 70.
A little less then 3/4 tank of gas.

R/T .673
60' 2.120
330' 6.013
660' 9.185
MPH 77.11
1000' 11.940
1/4 mile 14.256 @ 97.58 mph


She also ran two 14.40's in the morning and 1 red light.

[FlyByU]

From Ive been told (I have nothing to back this up :) ) For every 100 lbs, you are 1/10th slower. I dont think its quite that much, but it might be close. So in this case, lose 2/10ths off the 60 foot and drop the 165 lbs, that would have been a 13.8ish run.

It was her first time at the track in over 25 years. She wanted me
to ride with her.

Next time she's on her own.

[TopBanana107]

I timed my car a few weeks ago and this is what I got...

First time racing the 1/4...ever...all I had as mods were the aFe Stage 2 intake. i went around the water, and I didn't even spin my tires before lining up. I spun out a bit when I mashed the gas (which Cherry told me was a no-no). I've since added the superchips but haven't been back to the track yet.

I had been hoping to run sub 14, and more than 100MPH...i guess i could live with 50%!

[Fester]

Looks like that will not be my last time out :)

[FlyByU]

Its addictive as heck. Once you have a "good" run with no mistakes, you are hooked forever. Then its the chase of having that "good" run happen again :)

Its all about the launch, you will feel it when you get it right.

[Absocharged]

Here is the trick with launching.... From my exp with my car.
Do a good burnout outside the waterbox... maybe 5 sec of wheel spin.
Stage up.........
I launch at about 1700-1800 rpm or so not to much and when the 3rd light goes i smash it to the floor..... i have never eased into the gas. A SRT8 yeah maybe thats what they need cause they will spin more but for my car if i do all above i get a little chirp out of the box and bam 2.0 60 foots.
Your car has almost the same mods, i would try that first.
The hardest part for me was doing the burnout cause i didnt want to mess my car up. But thats part of racing i guess lol

[CRF450RR]

Looks like that will not be my last time out :)

Don't give up............

[FlyByU]

Ya, every car will be different, no doubt. I cant just floor it out of the hole, waste of time. 2.0 60 foots arent that great, you should be trying to get 1.90's or better. Dont get me wrong, 2.0's are not horrible, I get them all the time. Im just saying you have room for improvment and if you get down to the 1.9's or lower, you will have a much better ET.

[CHERRY]

To be honest a stock type R/T will be hard pressed to break into the 1.90--1.99 range. Especially with HAL and the ESP. If you have the buttons in the steering wheel go to the screen where you see the water temp. You want to let the motor cool off to 135 and launch between 140 and 150 degrees F. That will give you your BEST et. Remember to put ice on the intake with the engine cover off.

I have to agree with this. These cars just weren't intended to be good at the track with the stock set up. Every time I floor the gas pedal with the esp on, the car falls flat on its face. If I floor it with the esp off, I can still feel the rear brakes kick on a bit. Its very annoying hearing and feeling that sound and vibration the anti lock brakes make in the rear when the car wants to put power down to the pavement. I have been tempted to do the esp mod, but my balls just haven't descended enough yet. I think if you love this car but want a car for the strip, wait for the challenger. It'll be 10 times the drag car the charger is.

[blairian]

:knockout: could you explain...?

Icing the intake is a way to ensure that after track runs the air running through the air intake system stays cool

For an example of why this would help, drive your car around for a couple of hours and feel how hot the who air intake system gets, along with the metal thing that intake connects to, the term escapes me as of now

this in effect keeps the air denser (as it is cooler), and allows a larger "charge" to enter into each cylinder, therefore producing more power = more track consistency (for bracket racing), and possibly better times all around

of course this is all works according to the laws of physics and in theory but the actual efficiency and use is still debatable when used for very short periods between runs

[wickedchargerrt]

Hell the way the track is around here its impossible to get into the box around 135. My car seems to shoot up to operating temp in a matter of a few minutes. I cant find my slip now but i got 14.1 at 98.04 first time out , esp off , in autostick. All i had was cold air intake. I'm hoping for tha t100 mph mark but the end of this year but all i've had money for lately was the tstat. I followed cherry's post on another thread (minus pull spare since we were an hour from home, and we forgot our ice)

I'll see what my 60 ' is when i find my slip cause i'm like above post where i can feel the brakes doing **** even with esp off ( i know its only slightly disabled) . Time for rt junkie mod.

[FlyByU]

Ya, brakes cant help your 60's. Get the esp mods asap, lol.

[07superbee]

what advice do you have for better launches? To be honest last night was my first time out ever on the strip.

What i do is i take the air presure in my rear tire's down to 17p.s.i
do a bad ass burnout
load up the torque converter to about 1800 rpm
race with your gas light on to reduce weight
Hope this help's

I get it, Thanks

Mine's on the signature :smoke: :grin: I live in south florida

[Hemi_girl]

By comparison, I raced my stock Daytona on Sunday, and the best time was 14.25. The average was 14.36. Street tires, no burnouts, braked and launched at 1800 rpms. Best 60 ft was 2.016, fastest MPH was 98.21. RTs don't matter in ET, so I won't mention them.

I only make 3 runs at a time, and use ice to cool down in between.

Someone told me that if you hold the shifter to the left, you can higher rpms before shifting. It will still shift before redlining, but should help with times. Too bad he told me AFTER the race.

[DonatoM3]

In the manual it says holding the gear to the left chooses the best gear for the car to be in at the speed.

[stealthrider]

Never heard that before. He said to hold the shift lever to the left for the entire run? :confused: :confused: :confused: If I move my shift lever to the left when in drive it puts me in manual mode at the next lower gear.

[Hemi~C~]

All, IMHO when it comes to launching the 5.7 LX on street tires most of the 1.9's that I achieved or observed originated from launching from idle/1000rpms then rolling on the throttle....ESP off (fuse 17 still in), front tires pumped to 50lbs, rears at 30, using a short burn out to clean the tires off (avoiding the water box).

I only loaded the stall converter if traction was questionable due to the fact that it often times resulted in a slightly softer launch. I believe most of this is due to the fact that the suspension is preloaded and also the spark timing is reduced when the engine is under partial load.

Cool engine temps are important...but more important than that are hot oil temps. 140-150 engine temps are too cold in my opinion. Some of my best times have come from launching the car in the 180-190 temp range....running round robbin from a previous run when my oil is fully warmed up. I typically loose mph if my oil pressure is still above 30 psi at idle (indicating oil is still has not warmed to operating temp, causing a loss in power) vice the 18-20psi it has when fully warmed up.

[FlyByU]

Thanks for your input Chris. Nobody knows better than you and your insane fast times.

[stealthrider]

Question for those with the 1.9 60' times on street tires...I'm guessing you all don't have the crappy Conti's? My Conti's will not grab for anything... What tires are you running? My guess is the Goodyear's

[daytizzy024]

I'll be heading to the track tomorrow, just want to make sure. Best way to launch with this car is in autostick, traction off, and IDLE?

[stealthrider]

Myself I launch in "D", ESP off and bring the car to 1500 rpm, but someothers have had good times launching at idle. Try both, see what works best for your car.

[bobbuck555]

I ran at Englishtown NJ back in March. It was 41 degrees and I iced the Intake. My car is stock except for No esp and a K &N air filter. I ran a 13.75 with a 2.0 60ft. The weather is a HUGE factor. I ran in auto stick with 1/4 tank of gas. I launched at 1800 RPMs..I ran last year in august and ran a 14.0..

[FlyByU]

As you guys can see there is more than one way to do this :) It boils down to what works for you and your car. More ideas you get, the more things you can fool with at the track. Just remember how you did it when you get that great launch ;)

[Hemi~C~]

Very true... consistency is the key here. Once you find something that appears to work stick with it to verify the success....and only change one aspect of the launch at a time so you can limit variables. Over time you will definitely see what your car likes/dislikes. Hell, my 300C has over 100 passes on it and I still find myself trying a new settings on diff track conditions to see what does/doesn't work.... to me that is one of the best parts of going to the track.
