Drag/Acceleration Kia Stinger 1/4 Mile Times

[Tonkabob]

I think we need to revise all 1/4 mile times posted in this thread to include the trap speed after that run. There's a big difference between a 119mph car and a 117mph car even if the 117mph car runs a quicker ET.

i'll start adding traps as well. We will need a double ** on dragy trap speeds as Terry said running down hill at the end may increase the speed.

Was a little less humid out tonight so hit the private track for a few runs. Same mods as last time, JB4, BMS intake, BMS WMI kit (50/50 meth mix), 91 octane, drag radials. This time I added a can of Lucas octane booster. So more like 93 octane. And cranked timing up a bit with a JB4 firmware change.

Still couldn't get a good launch, but very happy with trap.

Awesome run. I'll get the leader board updated soon.
Do you know why you are getting ECU intervention pulling throttle on 3 of the 4 shifts? Fix that and you'll drop a tenth or two.

The Torque management between shifts is where the ECU tune will outshine piggy backs. I had pretty substantial torque interuption on my 12.13 run. My run would have been solid 11s with faster shift with less TM.

This is map2 , correct?

Looks like its off full throttle a quarter of the time. You are easy 11.8s if not 11.7s with out the intervention.

Boost floated over target a touch between shifts, throttle is used to regulate boost. Was of no consequence though as manifold pressure (psi2) didn't budge. Normally takes 40% throttle movement or so before you see a boost reduction in the manifold. So there is zero performance to be had there. But where there is huge performance potential is on the launch. If I could get that 60' down to a 1.8x on a well prepped track... Look out!

That closure is enough to effect performance for sure. It's not torque management though, but boost control. Should be better with v6, relog a 1/4 mile when you can.

I see you added the wheels but only to Terry’s mod list. Unfortunately this seems a little biased if you’re only including tires/wheels on Terry’s mods but not on anyone else’s...

Maybe the list should be turned over to someone not participating on it, lol. But I don't have 4 light wheels yet. Just 2. 2 more in the mail. Also I have a base GT without the factory LSD, so that should also be mentioned. It's the hardest model to get traction with.

I'm taking all suggestions and adding all new times with in a few days. I would have said 2 wheels for you but knew you had ordered 2 more, but you did run the time with only 2 so i'll note that on the update. When I can find it, ill try to also note LSD as a performance option as well for the RWDs. That would cover Stock Limited's, GT2s or aftermarket LSD. All 2019s GTs also have LSD I believe.

Tell me about it, the 19 with LSD was much easier to maintain traction with on launch.

 

[Doel]

Just my 2 cents, anyone

Tell me about it, the 19 with LSD (Limited Slip Differential) was much easier to maintain traction with on launch.

I've seen a few wrecked GT2s and yellow GTs, there's some LSDs out there at a junkyard somewhere...

I know I'm a little jealous. But, we got a great deal on the 18. $32,800 + tax. Was too cheap to pass up.

I wonder how long until a company like Quaife develops an LSD for the Stinger?

I have contacts with them, wavetrack, and MFactory, I just don't know what the market would be like for aftermarket diffs considering the 19s now have the LSD already.

On it. Need some better weather though. The V6 T2 build has been working pretty solid and car feels fast AF!

Fun with 1/4 mile data...
Compared my run vs @Terry@BMS and @TorkMe run vs Terry. My conclusion is Terry was putting down more HP than both of us but doesn't launch or shift as well. Tork tune in both cases gets a jump at the 60 foot and expands that lead up to the 1/8 th mile until the shift to 4th gear where Terrys big HP high octane methanol machine makes a comeback. 4th gear pull is over 1/3rd of the time of the quarter mile. Meaningless or useful, you pick. But you must agree that 1/4 miles are more telling than Dynos.
Looking at the deltas, if Terry could match both launches he would still be .01 and .03 behind at the end of the 1/4 mile respectively. But a 1.94 launch should get you that 11.99 which seems doable.

 

[Tonkabob]

Ok, ok, in know the suspense is killing you. Here is Tonkabob vs Tork (AWD tork tuned vs RWD tork tuned).
My launch advantage holds steady up until 1000 feet where he gains just a bit of ground. Both cars shifting the same and @TorkMe has a touch more HP.

 

[Ritz]

Quaife makes some nice diffs. The challenge here is that the Stinger is a very low volume car and probably not a whole lot of hard core modding going on. It would be hard for them to recoup development costs unless they could get some sales volume.

Cheers!

Please note... you are running our latest and greatest tune. My 11.99 run was running on a tune that is 4 to 5 months old, and I have since added more power and development on the Stage 2 tune. If I had to guess, if I were running the Stage 2 beta that TB is running, we should be closer to 11.7 and 120 + trap speeds. Hopefully this week I will have that pesky methanol system installed and start development on the Stage 2 + Methanol tune. I have to figure out how to get the factory turbos into the 10's
