Default Can someone explain to me the following (drag strip expert please)...

Just came back from the drag strip. I ran multiple 1/4 miles runs tonight, ten to be exact and once again the car pulled through without putting up a fuss.

First thing I'm going to say is that the
<b>G-Tech Pro</b> is <b>dead accurate</b>. I have full confidence that if I test with it again the numbers will be reliable. Mind you going to the track for $5.00 CAD, yes guys that's
$3.50 US for as many runs as you want with a time slip for every run now that is very cheap and fun.

<b>Track and weather Conditions:</b>

Compared to when I tested with the G-Tech Pro it was warmer, around 10 F warmer tonight and it was windy, maybe 10 mph winds that were cross wind to a bit headwind. I don't know how much the wind would have affected the times tonight.

Again tonight as the other night the times were very consistent. On my first ever run I Fvcked up big time, I got a 2.562 for the 60', 9.865 for the 1/8 and a 15.092 for the 1/4 @ 91.374 mph. Like I said lets forget this run please.

The other runs were in the 14.2s to 14.5s and all 60' times were between 1.9 to 2.06 seconds!
The 1/8 of a mile came in between 9.01 to 9.2 seconds and the speeds were between 97.2 and 98.1 mph. All the speeds are somewhat slower by up to 3.5 mph when compared to the G-Tech Pro runs.

In one of my best runs these were the numbers;

60' at 1.943 seconds, 1/8 at 9.012 seconds and the 1/4 mile at 14.22 seconds with a speed of 98.123 mph.

My best run of the night was as follows;

60' at 1.872 seconds, 1/8 at 8.971 seconds and the 1/4 mile at 14.16 second with a speed of <b>94.216 mph</b>, WTF!
The 14.16 seconds is only 2/100th off the G-tech Pro Time of the other night at 14.14 seconds.

<b>Observations and questions</b>

During most launches if not all, I got lots of four wheel spin. Would this partially explain the poor 1.8 to 2.1 60' times?
If so, how much faster could the 1/4 mile times have been if I got a good 60' time? What is a good 60' time?

In my best run I got a 14.16 time but a really low speed of 94.216 mph, how can that be? That is almost 7 mph less than what was recorded with the G-Tech Pro (the other night) and 4 mph slower than my second best run tonight. Mind you I did miss shift a gear, could that explain it?

The fact that it was 10 F warmer tonight, could that have affected the times? Also what about a small headwind?

Finally I ran against some WRXs and I beat them except for one that was modified and he beat me by 2/10th. I also ran against someone I know with a modified and much lighter B5 A4 with a PES Stage 3 with a T28 set up. He beat me but not by much either, about 1/10th. To be fair he says is clutch is finished and he could/would not dump it on the launches. He was also faster then me in speed at the end of the 1/4 mile. I could really hear his turbo kick in when he was coming up behind me.

In any case if someone with drag strip experience can explain to me these points I would appreciate it.

TIA,

Mike

Default Mike I'm not an expert but those are awesome numbers!!! Congrats Bro...

Your 60' times are very good, anything under 2 is very fast the quattro is doing it's job. It's good to see the little 1.8t make some great runs. My buddies M3 hit 13.8's, with 2.2 60' times. You've got a fast car my friend. : )

Default Great runs, answers inside.

As for your question about the mph. You have to understand that the trap speed is not a speed at all, it is a time calculation of the last 66 ft. This means your time moved thru that space was slower on your quicker run. This usually happens if you stretch out a gear to get a quicker ET, most of the time it is 3rd gear that you end up taking too far past your shift point. MPH can also get higher on a slower run if your 60 ft time is slower since your changing where your at in your power band as you pass thru the traps.
