That's not how 1/4 times are calculated and reaction time has no bearing on 1/4 time. As far as the numbers are concerned, you're right and wrong.I'm glad to see you were able to get the Fiesta under 15/s on the 1/4 mile with a stock setup.
Unfortunately your R/T time is under .500 that means you jumped the green light, in other words that 1/4 mile time is invalid.
If you add .203s to your time your 1/4 mile is 15.084s, however I would add another .100 to that time and that's being generous, 15.184s is your true 1/4 mile.
I've never been able to get better than .638 R/T time.
All you guys that are posting time slips, please only post slips that don't have an R/T time less than .500, it only means you jumped the light.
Really strong mph for stock! Fastest I've seen. Picking up 21mph on the big end, woo.Best ET run - 14.582 @ 96.5
Best MPH run - 14.777 @97.02
Both were at Mid Michigan Motorplex on 4/19/2015. Conditions were absolutely perfect. I am car #2022 and I was racing my friends Veloster Turbo with a upgraded ECU and exhaust #2021. I took 6 passes that day. This was my 2nd track day with this car. I have been drag racing for 25 years.
My 2015 ST is completely stock. It had 14,900 miles on it at the time. It is my daily driver and I commute 90 miles a day.
I was running 93 octane fuel. Tire pressures were 29 front, 42 rear. Traction Control completely off. I took out the baby seat and the spare tire.
I took 3 passes then let the car cool down for an hour. After I got the 14.77 I was ready call it a day, but my friend said 2 more passes.......I'm Really Glad I Stayed!
Best advise I can give is to launch this car soft and let it bite before getting into the boost. Nail the launch and the rest is easy.
