Drag/Acceleration Kia Stinger 1/4 Mile Times

[Terry@BMS]

Got tired of the RPF1 look so threw the stock rims/tires back on, and took a run this morning on map3 (no WMI), 30% E85. With 1st gear set to -5psi and 2nd gear to -1 psi it ran 12.27@118.5. It has a full tank of fuel in it right now so I'll try again later when it's close to empty and can hopefully hit 119mph. For RWD cars traction is our primary enemy!

Threw the diy intakes back on yesterday and tried six runs all the way to -4.0 in first -3 in second.... still spinning tires for a best of 4.76sec 0-60.

I’ve got to try the sway bar in the rear and a wider tire.

I though the rear sway bar helped on turning not straight line ?

Keep upping the boost reduction until it somewhat hooks! My 0-60s were around 4.4s.

It will also help keep the passenger’s side rear tire from lifting, springs should/would help, too.

I been debating if i want to do the rear sway bar? if its worth it ?

 

[TwinSnails]

I’ve heard it’s worth it, but normally from my experience it’s gonna increase rotation from the rear end. In an AWD car I’d love that benefit... in a RWD car, you have to be careful... might rotate too much or just perfect. I’ll be started on the soft setting when I do it to test.

keep me updated please...been thinking for my next mod doing the rear sway bar...

I see you are in FL, but I agree those are high IAT’s. What other mods are on the car?

If none beyond bolt-one, it’s pretty apparent that your 93 octane is not enough for Map3. Due to your humidity and FL temps, you’re going to need a new FMIC, and you’d be a perfect candidate for WMI. Your car is pulling a lot of timing on Map3... simply. It hates it.

What all have you done to the car? I know in NC during the summer it’s hard to keep IAT much lower than 95-100. But you guys have more humidity and normally less peak temps... so I would think after allowing the car to hit operating temps you could maintain 95*.

Also @CFLGT2AWDStinger have you posted the logs to n54? Annnnnnd this would have been better placed in the JB4 thread where it would be found quicker by @Terry@BMS ... which will now be found lmao.

Thanks for this and sorry for late response. It was like 55 60 degrees out but the track is super hot.. like I've seen the drag guys shoes melt to the tarmac. My normal operating iat is around 90s ish not running hard.. I stopped opened the hood and it sit for an hr between each run.. I have the single catch can setup so that might be part of it.. the piping heating up the air otw to the intakes and the breather in the engine bay.. kinda wanna open up the intercooler and check for oil and such..

One thing you're overlooking - how many other times have been posted from a run with 17 degree ambient temperature? This is gold for turbo cars (cold, dense air) and nobody seems to understand how important that is.

There has been so many pages of 1/4 mile thread and yet this is THE most important factor of all of those variables and its only brought up like what twice ? I mean what the hell why arent the the top ten times listed with Temps and Density altitude ??????? Were missing a huge variable for comparisons sake. I mean dammit guys think about that for a second get out of the whole hes got this mod, its the draggy blah blah blah.

Look at this fact: A stock stinger running at a density altitude in the 800 ft range will run a faster time in just about every 1/4 metric then a stock stinger running at a density 3200 ft even at the same track. Or in my case 7600 ft density altitude on a cold 50 degree day. The same thing will happen with a tuned / modded car, the one with the best density altitude is going to have a clear advantage. Mods dont make you immune from density altitude.

Use this tool guys and make your runs on the lowest possible density and watch times drop.

While you're absolutely correct, it doesn't seem that many people care about these variables. People are gunning for the fastest ET here, regardless of mods, AWD/RWD, DA, etc. Hell, even trap speeds don't matter here.

 

[Terry@BMS]

I second adding DA to the list for each run, most 1/4 mile lists include it.

LAP3 bragged on Instagram yesterday about having the fastest 1/4 mile time for an AWD Stinger.

The car in question ran 12:13 @ 116.7 with FULL boltons and Pro-Tuner.

I couldn't help but to chuckle a bit, since that run is number 7 on this list.

[Michael Locke]

Our 7, 8 and 9 are all 12.13s. But to be fair we are very dragy heavy especially with the AWDs. But lap3 is .35 off the best dragy.
@Michael Locke you have been doing dragy and strip runs, what is your take on the difference given slope, temps, heat soak?

There is definitely a correlation between downward slope and times. It's very possible to find a perfect road that favors your preferred result, I just wish I could find that road!

My best Dragy was 12.07@114mph and +.15% slope. I've seen better times but never if rarely ever on +% grades and more than often, are on the threshold of being invalid due to them being almost -1% downhill which in some case meant a 25-30ft drop in elevation.

Now that may seem minimal in your mind but when it's only fractions of a second, any advantage is exactly that.

 

[Tonkabob]

1% of 1320 feet is 13.2 feet, so that is the max drop. But a full 13 feet is still significant.
But isn't your uphill dragy time .1 slower than your best slip? So temps and heat soak could be a big factor also.

My best slip is 12.17, my best Dragy is 12.07 both were done in similar conditions. DA's are a factor as well. Yes I'm aware of the 13ft but Dragy shows elevation scale on the axis in ft. It makes an great line to give you an idea of what the road would look like if you were looking at it as a "horizon" view.

Sir at that is the honest truth lol .... I don’t even think Terry can argue that lol ... that’s facts ..... on paper he got it lol

Elevation on the left axis, speed on the right axis, color matched as well.

 

[Adamdan]

I get my dragy today and after I get my 0-60 settings locked in I’ll probably give a 1/4 mile a go.

 

[Terry@BMS]

FWIW I've found there are a lot of Stinger owners who aren't really active on this forum, at least not yet. I've heard feedback of from various really low 12 cars at tracks not reported here. No one has told me they ran 11s at at a real track but I'm sure it's coming.

Since traction is such for RWD cars we're working on a couple new Stinger mods that may help out in that department. Will keep you guys apprised of the results.
