Jumping all over that light huh? ;)

Nice run......what RPM were you letting her out at? I assume you just eased the clutch out?

91, next time I'll try 93 and see if that makes differance. If I go to Bandimere (5800ft) I'll try some 104 for the hell of it :lol:

Remember the Subaru ECU requires about 40 miles to adjust to race gas. So drive it after you put it in. I made this mistake once.

How exactly do I go about reading that slip? Anyone care to do a breakdown please?
Hmm, well the light was green for .028 seconds before I left the line (perfect is .000 so I was very close). Then it took me 1.868 seconds to go from 0-60 feet. 5.513 seconds 0-330 feet. 8.590 seconds to hit an 1/8 mile. 11.258 seconds to go 0-1000 feet and 13.530 seconds to go 0-1320 feet (1/4 mile). When I finished the 1/4 mile I was going 99.11 miles per hour. Hope this is what you meant.

It's an excuse for slow people to feel better about themselves...

One went 13.50s @ 101 mph at sea level. Sunoco 94 octane is available at local gas stations. This seems to be the norm for showroom stock, not what you see in the magazines. A .500 light is perfect so that if you red light you can tell by how much. A .400 reaction time means that you were a tenth of a second before the green light.

Beginning at the K&N Filters Winternationals, the opening round of the 2003 POWERade Drag Racing Series, NHRA will implement two significant changes on the starting line for the NHRA national events.

First, the numerical value of a driver's reaction time will be modified at each of the 23 national events. The modification simplifies the process of understanding a driver's reaction time to activation of the green lights on the Christmas Tree. Previously, a perfect reaction time for professional, and some sportsman drivers, was a .400. For the remaining sportsman competitors a .500-light was considered a perfect reaction time. Under the new changes, the timing system will be modified to display a perfect reaction time as .000 for all categories. This change only applies to the 23 national events that make up the $50 million NHRA POWERade Drag Racing Series.

On a pro Christmas Tree, a .399 light, or anything lower, would be considered an early start, activating the red light, which would result in a disqualification. Under the new system, a .399 will now be displayed as a -.001, a.398 will be a -.002, and so on. Anything from a perfect reaction time of .000 and above will be a legal start. The new timing system in no way affects any driver, vehicle set-up, or any other significant aspect of the competition on the drag strip.

Also, as previously reported, NHRA will implement the use of LED amber lights on the Christmas Tree starting system, replacing the traditional yet damage-prone incandescent lights.

"The biggest advantage is that the vibration, especially that caused by the Top Fuel and Funny Car classes, won't cause the LED bulbs to burn out like it will an incandescent," said NHRA's Graham Light. "Amber bulb failures, especially during full Tree countdowns in the Sportsman classes, lead to re-runs and other problems. We are trying to avoid that problem as well as step up our technology.

"We tested the new bulbs without problem during preseason testing in Tucson," added Light, "but racers attending the Winternationals and subsequent events are advised that the LED lights illuminate quicker, by about three-hundredths of a second, than the incandescent lights."

What about the answer to this question? Did you have to 'pop the clutch' to get these sorts of times?

I don't know what you mean by "Jumping all over the light". I didn't "pop" the cluth or ride it. Got the rpm's up to about 5k, let the clutch out easy. Little tire spin in the rear and I'm out. I think 1.7 60fts are possible at a better track.

I ran my WRX at New York International Raceway Park here in Western NY on Wednesday.

here's my best timelsip. The car felt like it had more in it, but I was having a tough time getting quick 2-3 shifts. Guess I gotta get used to it more and maybe break in the shifting mechanism a little better. fun time!!

Temp 84
RH 64%
R/T .664
60' 1.849
330 5.587
1/8 8.71
MPH 78.64
1000 11.376
1/4 13.635
MPH 99.39

track elevation is on or just below 1000' above sea level I think.

not being a drag racer myself I always wondered why a .500 reaction time was a perfect one. Anyone care to explain?
theres a half a second in bewteen the last yellow light and the green light.......hence perfect is .500...thats on the sportsman tree(light light light GREEN)

on the other kind of tree(all 3 lights and green) it takes .4 seconds from the yellows to the green.....like in NHRA events....they use this tree(cant remember the name)
