New 1/4 Mile Times


AWDxBOOST

Recommended Posts

three weeks ago i ran a 14.52 @ 95, and just tonight i hit a 14.36 @ 98 with a 2.258 60', worse than the 2.170 i got when i ran the 14.52

 

bone stock performance wise :)

 

only engine changes:

avo bov

silencer removed

 

what was great was i cut out a wrx with a ecutek reflash, turboback and uppipe by .4s :D

Most impressive trap speeds! Are you sure you are bone stock? Seems like an awfully strong mph..... What did the car weigh? Track conditions, including weather data? Pump gas?

 

If it really was stock, you definitely have a ringer!!!! Just get your 60' down a few tenths, and you are in the high 13's, very nice indeed!

here are full times for the slip

 

r/t .579

60' 2.258

330 6.127

1/8 9.302

mph 78.15

1000 12.046

1/4 14.361

mph 98.47

 

the mph is way high, when i ran my 14.5 it was at 95 now that im lookin at my slip, not at 97...

 

all i did was take out silencer after the 14.5...it was about the same conditions...50ish degrees, track wasnt really slick, but not that tacky...not humid...93 octane

 

still a really high trap for awd

I'll bet you find that with a better launch your mph goes down similarly.

 

In a 1/4 mile run you're testing acceleration vs. time and acceleration vs. distance. If you cover the length .2 seconds quicker, that's .2 seconds off the time the car has to accelerate, hence the lower trap.

 

All of this is within reason of coure. You can't purposefully run a 20 second quarter mile and expect 120 mph traps as a result :D

Can you explain how you lauched? I'm gonna try and head to the track either this friday or next friday. Looking to try a few different things to see what works best.

Thanks,

Dave

No doubt hooking gets better 60' and ET but MPH will suffer a bit. Again I have always said who cares i'll take ET over MPH anyday.

Went to Byron, IL to Byron Dragway today. Temps were in low 40's all day. Some cars did some impressive times. Out of about 18 runs (scrap 2 because of timing errors) I got I think 3 in the 14.2 range, 4 in the 14.3 range and 4 in the 14.4 range IIRC. Never broke the 2.000 60' times but had a few rather close to it, like 2.032 and a number under 2.100. Traps of my better times were consistently at about 98-98.5mph by the latter half of the runs and finally started to get a launch rythm down. I even got one R/T down to .056,

 

Here's what my best time looked like:

R/T: 0.398

60': 2.032

330: 5.905

1/8: 9.133

MPH: 76.59

1000: 11.899

1/4: 14.236

MPH: 98.31

 

Two runner ups:

R/T: 0.506

60': 2.060

330: 5.894

1/8: 9.094

MPH: 77.87

1000: .000 - didn't record

1/4: 14.264

MPH: 94.01

(Think I did a mis-shift into 4th on this one.)

 

R/T: 0.127

60': 2.066

330: 5.927

1/8: 9.174

MPH: 76.35

1000: 11.947

1/4: 14.285

MPH: 98.38

held the car at about 3300 rpm and feather out the clutch for a smooth launch

I was probably between 3500 and 4500 for mine, the tires did chirp slightly but never any wheel hop. The drag strip is a completely different launch than a light or anything else, so hard to really negotiate without some practice IMO.

 

Here's a vid from the event that I put together. A friend took the footage and I did a compilation of it. :)

 

VIDEO It's about 30 megs IIRC and in quicktime's MOV format.

Awesome video!!! Did I see it right...the Evo did a 12.97 at 107??? Was it stock? Why was the last run so much faster than the others? RT? Also, for your times, what mods?

I agree to a point.

ET's and traps have A LOT to do with launches too.

As you said, an intentional 20 time won't get you 120 mph traps.

The key to getting the best ET and trap speeds is getting a perfect launch

and shifting perfectly.

 

In this posters case, with a better launch he'd be in the 13.9's and probably

pushing 98.5+ traps speeds.

I think, and it's been shown, to be the best case scenario times for a stock manual LGT sedan.
