Drag/Acceleration Kia Stinger 1/4 Mile Times

[Terry@BMS]

Both dragy and tracks use a 1 foot roll out. Dragy is very accurate, I think in some cases more accurate than the track timing equipment. We've had plenty of very fast customers do side by side comparisons and the difference is always less than .1th, less than 1/2mph trap. A lot of people leave dragy active during real track runs so they can get 0-60mph, 60-130mph, etc, so you see plenty of data on that front.

You can't pick and choose what a real 1/4 mile ET is. Dragy verified vs timeslip, it's all the same.
One of the most important variables (and what I think you're trying to say) to an ET is DA (density altitude) which NEEDS to be factored in. If I live in Atlanta and run an 11.9 with a current calculated DA of 54 feet, I am NOT going to run the same time in July when the calculated DA in Atlanta is 3522 feet.

Agree , what I am also trying to say is that the valid times accepted should be 1/4 times at track or dragy times at the track .... I do understand the differences in altitude, temperature and so forward has an effect on time.... A dragy winter run on a street that has a down hill slope should not be a valid Times.. it can be use as reference but not valid that’s all I am trying to say ... maybe I am the minority here but for valid runs we should spilt the list with dragy and track .... that’s is all I am saying not trying to offend anybody here

I agree timing looks valid but the slope issue is concerning. I think you probably know more about the Dragy over everyone since its a big ol JB4 ad when you open it every time lol. Can someone go down hill up to 1/8 and then straighten it out to fix the slope before the 1/4 mil time to have a valid dragy run?

My DA's that day.

Seems like y'all need to decide if a quarter of a mile is only a quarter of a mile if it's on a drag strip in August.

Yes, slope can be cheated a bit by going up hill at the start when you're traction limited and don't mind giving up the power, then racing down a larger slope for the rest of the run, and come in under the 1% total variance. But slope is plotted on the chart so you also clearly see when someone is doing that.

The elevation component of the GPS is the least precise and if you drop a satellite during a run can wind up with an off reading and an invalid run on a track that previously was valid.

 

[Terry@BMS]

Agree Terry dragy is accurate when used at the track compared to track run at the same track ... I said that before .... my issue stems from trying to validate dragy runs on the streets lol on winter weather or when the roads are downhill .... I also understand you sell dragy and it’s on your agenda to sell them and advertise them as the norm ..... Terry just out of curiosity when will you hit the track ?? Are you waiting to be 100 percent sure you will get a 11 second pass before you do so ? Come on Tork hit 11’s a while back , still waiting on you to hit the track and post videos and results....

Nearest drag strip is 4 hours round trip. When we do make the trek out there it's swamped and you might get 2 or 3 runs all day. We normally take the faster cars out when doing that. As to who on this forum has or hasn't run whatever time, it's really of very little concern to me. I'm here to help our customers run as fast as they can and win races.

Got ya. Thanks for sharing that.

So to be clear what's everyone's fastest Dragy vs. 1/4 side by side?

Dragy 12.07@114
Track 12.17@116

I'd say I've got a solid 12 sec car. So far with minimal mods, I'm happy with that.

 

[nhcowboy28]

Bottom line, draggy is exceptional at knowing your car’s performance before/after mods. It is accurate relative to you location/altitude/humidity/time/date/etc.

The same argument comparing true drag strips thousands of miles apart.

The only way to REALLY know if your car is faster than the car next to you is to strip em or back to back draggy in the same place/time.

Be safe on public roads and have fun.

The accuracy comparisons are only valid if both the dragy recording and the track recording are of the same run at the track. Beyond that the track itself will have some traction benefits, while private tracks (dragy) will generally have weather and slope benefits.

Any further personal attacks or argumentative posts will result in suspension from this forum. End of discussion.

I think a lot of people are going to be happy with that as well. The difference between a very high 11 second pass and a very low 12 second pass is not enough to care about IMO. These times would be unheard of a few years ago on a car like this

Agreed the car is amazing wether it runs a 12.5 or 11.9 ....Regardless the Kia Stinger surprised me even on stock form .... I bought the car for the wife and fell in love with it .... and honestly my other 2 cars are faster than the Stinger.... I know for this car it still needs like a year or two until it fully matures .... once there are actual ecu tunes that are tested and highly developed meaning the tcu, LC and other parameters are tunable and tested it will really put the stinger performing and reach limits we would not think off ... it will run 11’s reliably with minimal mods ....there will always be a market for piggybacks due to the fact their cheaper and the convinience of easy isntallation and removal and of course the warranty aspect of it .... but make no mistake when there are proper ecu Tunes developed for it the performance that will be reached will not be reachable by a piggy back .....once more ecu tunes come into play the price should come down... if a big company like Cobb/ HP tuners taps into the stinger market will change the playing field .... I personally love the Kia stinger although I am more of a Lexus guy but this car is impressive to say the least ....

Guys I posted the slips over on the 0 to 60 along with dragy.......Dragy is what it is...as they say
If it wernt for dragy and yall here on the forum my duff would be on the couch...so it was great to get out on the strip.... I wasn't there to race anyone..I was there to feel out the car and the dragy and the JB4....a lil bit of racer was in me though...a caddy ctsv whatever came over to me and said lets race...that was number one race and I beat his azz....he came over and said he wanted a do over cause his launch control messed up...lol...said his car runs 7's...well okay lets do it again...that was race number 3 where my launch control fell flat and he beat my azz... the best race was number 2.. a late model dodge srt 426 hemi wanted to race....but geez I havnt been on a strip since 2005...everyones wanting to get it on...fun stuff....of course I was sleeping at the light and making sure dragy was reset and he put 3 cars on me at the start but I finished right on his door. the second to third shift was badazz on this car and I almost got there....people came over and told me how impressed they were with the car...and oh btw what is this thing? Guess ill go back this weekend now ive got a dedicated phone for dragy and jb4....lol ...my 0to 60 was 4.64 4.65 just like on the street pretty much....but the car was hooking up good so I don't know why my 0 to 60's wernt better ?
maybe im not recognizing wheel spin? I think I felt spinning all the way thru second cause when shifting to 3rd the car lurched forward with authority....am I right? Wash

 

[Tonkabob]

Can you log pedal position?

Here is a 0-60 (no LC) with pedal position, relative throttle, and manifold throttle.

your best 60' was just over 2 seconds and the worst 2.2. It definitely sounds like you were having some traction issues. How cold was it? What were your tire pressures at? If you somehow got it down to 1.8 you would be in the 7s, or dang close anyway.

Thanks Doel that's what I needed to know it was nice 65 DA was 385 ,street tire pressures....my 0 to 60 was 4.64 and 4.65 on the two decent runs.....this is weird they are the exact same 60's as what ive done on the street on a good day with wheel spin I recognized ....when coming to staging they moved street tire folks over to the right side of the lane to stay out of the slick tire starting spot....my buttometer sez the car hooked up....lol.... Wash

yeah, street tires tend to eat up the track prep, still should have had more traction than the street though, I dunno. Could always try lowering your rear tire pressure, you could go as low as 25ish, helps sometimes. Just make sure to bring one of those little air compressors with you.

Hope the weather dries up soon around here, have some new stuff to test!
