Drag/Acceleration Kia Stinger 1/4 Mile Times

[brancky3]

My point was where is the speed coming from? 2.4 lbs less boost, 10 degrees higher intake temps, and throttle close on every shift.

I haven't seen the log personally so I can't comment. But, I distinctly remember a certain someone calling out the JB4 for running more boost, more timing, and making less power. So I guess it's a mystery.

Less weight?

I think that analysis above is bunk but who really cares.

The best way to do "rolling race" simulations is to compare 60-130mph times. As a data point our development car generally runs low 10s staying in it through 1/4 mile runs. I haven't tried a dedicated 60-130mph run yet starting in 3rd though. Hoping for high 9s.

Ok I did do one "Roll Race" but was afraid my friends would find out so only did this once. (Like riding a moped)
This was a 11.89 run at 117 MPH vs Terry running 11.91 at 120 ish. Different runs than I showed before but this is indisputable data since it is speed based not time.
I win 60-70, 60-80 and 60-90. After 90 is a long dyno run 4th gear pull and Terry wins everything after that. So even though Terrys car is 3 MPH higher trap in the quarter, I roll him 60-90 -in a short highway sprint. How is that with 200 lbs more weight and less HP besides shift time? (Since this run I have dropped .12 and added 1 MPH)
Shit that Tonkabob guy is always freeking right.

This is his 11.98 log. Like always it's all in the launch.

Boost peaks around 15psi due to the very cold weather but it's right in the efficiency window of the turbos. Timing is great. The "throttle closing" has always been a red herring (note manifold boost never moves from prethrottle). Map2 is just a great all around map. Note AFR is less than ideal as it's on V6 firmware so he's got more performance in it at the same boost level, IMHO.

10.81 60-130 is decent but it's quite a bit slower than our 60-130 which didn't get full traction until after 60mph. I don't think you'd win a rolling race with us at any normal starting speed. The momentum from the great dig launch is just making you think you're quicker than you are. 0.82s is like a bus length margin of victory in a 60-130.

right foot

Guess what I found?

 

[brancky3]

That's pricey!! Do I see your e85 is $2.3xx as well?

 

[Get Stung]

yeah but I'm prob only in for 2gals traveling light this time.

Yeah i wouldn beat you in many real world roll races but my point was I'm faster to 90 as i said before and was better able to show that with this mph data over ET data in the quarter. My launch is not helping me at 60 mph. 60 is 60.
People were arguing a 3 mph faster car would always pull the lower trap speed car. We would nail it at 60 and by 90 I'm a car length ahead and would back off and go have a smoke and find my next victim. (Joking, i dont street race)

If you look at the time stamps in his file it takes 13 seconds to go from 3 to 116 mph. Not saying the log timmer is perfect but it is another data point.
Throttle closure isnt a red hearing as with out fuel and air all the boost in the world does nothing. You also dropped time when you fixed your throttle on shifts.
Here are two of my 12.03 logs with same or very similar 60 foots to Get Stung. Different runs but one shows iat and the other throttle.

No I didn't. You claimed I did a few times, like you guys claimed I removed timing pull at the shifts (couldn't if I wanted to), and frankly I only have so much energy to continually correct you guys. One of my best times 11.94 had all sorts of throttle movement. It seems you still don't understand what I'm telling you about the boost in the manifold. Maybe it will sink in another way. The throttle is around 50% larger than it really needs to be. You'd still make full power with it only open 70-80% an entire run. So when talking about throttle movement and performance only movement that drops manifold boost is relevant.

Quick question during this debate we got going on here. Does the JB4 record my IAT? I'm not finding it.

Stung Race fuel and e85 together at one pump 112...geeeez...you're living the dream! Wash

It's there.

 

[Blitz]

It's there.

x10 = degrees I'm guessing?

 

[Terry@BMS]

View in the JB4 windows interface and it will appear in the chart scaled properly. If doing your own thing, yes.

I'm heading out Sunday or Monday. In the end they'll argue dragy varies from car to car. 3 of the top 4 times are dragy. If map 3s clicking and I think she is I'll be top2 and theyll have another log to analyze and pick apart.

I want it to be accurate but its an out lier. You need a slip in the spring or we need to trade dragys. Blitz is testing mine now so if he runs 11.6 then my dragy is defective!

With map3 or map5. v7+ firmware, and more octane, should add a few HP, which always helps!

This is turning into 2018 all over again...

Except... I am missing from the threads, ran out of popcorn

I agree its ALL about launch!. I tried running the draggy with my 24540R19s winter tires and I'm going nowhere fast. My best 0-60 was 5.02 (with 200 lbs if sand) lmao. I'll try it again tomorrow with out the sand it's too damn cold to get back out there.

200 pounds of sand ?? Lol
