Stock '16 ecoboost 1/8 mile

[3oostdmstng]

Out of boredom tonight I went out with the need to record a 1/8 mi run with the track apps. I've owned this car for 3.5 years but never actually did a run WITH the track apps on.

I want to get some input from some of you if my numbers look "okay" for a stock car, and what some of those #'s mean.
Im located in Central Florida.
Run was done around 930 pm with humidity at 77% and 85F.
88, 800 miles in the car.
93 octane in the tank since 10k miles in the odometer.
I found flat dry road. Made sure no one on the road and no cops
Soft launched at 1500 rpms.
Only monds: k&n drop in filter and mbrp catback.

Does the 1/8 mile and mph look about right?

What is a 60 ft and 330 ft (is that like a 0-60?)

Looking forward to some input!
I posted it here instead of on the 2.3T because I know of you GT guys used to own EB's.

That would equate to an upper-mid/upper 14 second 1/4mi pass.

Probably about right for the heat.

Damn , really? mid to upper 1/4 mile? lol
Do you know how accurate the track apps is?
Ive seen some videos of ppl using dragy and getting similar results to mine in cars that are "rated" slower than mine.
Granted I only did one run, didnt do a few to see if I could get better. And , yes, its a bit hot and HUMID out.
I guess its not too bad for almost 90k miles in the car lol

I cant find online what is the "rated" 1/8 for the EB, only its 1/4 mi.

Yeah, your 60 foot is objectively terrible, that's the issue. It's not the car's fault though, you just launched it too soft or spun. The rest of the numbers look pretty good. If you can get your 60ft (the first 60 feet of a 1320 foot pass otherwise known as a quarter mile) under 2 seconds then you'll be doing a lot better.

Track apps isn't perfectly accurate but it's not inaccurate either, since it's purely going off wheel speed and doing the math to figure out your speed and times. You'd have to purposely trip up the computer by changing gearing or wheel diameter without informing it of the changes.

Yes. Your 60’ and the MPH tell the story.

The car is capable of doing better, it’s all in bringing the 60’ down. They’re capable of running a low 14 bone stock. I’m sure some have even cracked a high 13 off. Launching and weather are the two biggest factors.

I’m not sure how accurate the app is compared to others, but from a few threads I’ve seen posted it seems like it’s fairly accurate.

Yes, I typically "soft" launch @ 1500 rpms as I feel I dont spin too much (or at all), though, of course, depends on the road conditions.
I will keep an eye on the 60 ft! Ill also wait until temps get a bit better, yesterday it was still pretty hot and humid even though it was night time (damn summer time!)...

One last thing, since I couldnt find it online, what would be a "good" number in the 1/8 mi and mph for the EB mustang? I know for a pre '18 the 1/4 mile is about 13.9 @ 98 - 100mph (with auto and good conditions).

Thanks!

Appreciate the input! Ill work on the 60 ft ...
My tire psi were at 33 each..does that matter a lot?
Anyway, Ill also wait until temps cool down a bit. I was able to achieve my 2.2 and 5.5 seconds in 70's temps... but yesterday was still hot and humid.

No problem.

Tire psi is a factor but not so much on the street as it is the track. Biggest thing is just not overinflating the tires.

Your 5.5 0-60 run would probably be a 9.3-9.5 1/8th mi. I used to have a Focus ST (2.0 eco) and the heat exchanger couldn’t handle hot days and hard acceleration.

 

[Blue Moon]

I got my best 0-60 time with rear tires at about 26 psi, 5.4 secs, stick shift. I don't think I've gone below 5.6 with full tire pressure.

I said I would wait until colder temps but I couldn't resist. lol
I did one more run tonight in the same spot just to see if MAYBE I could improve it. I did. by a tad.

9.5 sec @ 78 mph. (from 9.6 @ 78 mph)
60 ft went down from 2.6s to 2.3s <----- I feel pretty confident I can still get better at this
330ft went down from 6.4s to 6.3s

I spun more than yesterday , though. Humidity was 80% Temps 78F.

I was looking at this website http://www.wallaceracing.com/8th-quarter.php

According to that : my numbers = 15s @ 96.78 mph 1/4 mile OUCH lol
I thought maybe under better conditions, lower temps that a 9 sec @ 80 mph would be do-able. (using that site)...idk about its accuracy..

As for my 0-60 run, it was a March and temp was about 72 F with low humidity. Thats all I remember. I Just launched the car at 1500 rpms and was able to achieve that. I did a few runs that week... WITHOUT launching id get 5.7 - 5.8 secs. The following day I did a run in 92F temps just to see how bad it could be and did a 6.1 s.

What I DID find surprising was that my 2.2 and 5.5 sec were achieved by just putting the car in sport mode (shifter) and letting the car shift by itself, which usually does so around 6300 - 6500 rpms. When I short shifted with paddles at around 5500 rpms I'd get the same 0-30 but 5.6 secs 0-60, so more or less about the same...I bring that up bc I read that its best to short shift the EB due to the drop in power after 5800 rpms , or so. Maybe thats more on the top end? idk. Just thought Id share.

 

[Shifting_Gears]

Are you leaving traction control on or off? That’s another variable. But yeah, letting the trans shift itself will normally net the best times.

Good improvements on the 60’.

Mines a NON PP auto. I read somewhere that the manual PP ( as I see you have) might be slower bc it requires a shift to third?
idk but my times were achieved by just putting the car in S mode, launching at 1500 rpms. Temps were 72 F in relatively low humidity. WITHOUT launching id get 5.7 - 5.8 secs, tire PSI at around 31- 32. The following day I did a run in 92F temps just to see how bad it could be and did a 6.1 s. T

Yeah, it really does net best times.
On my run yesterday, I did turn off TC.
In todays run I did not.
