Not directly, anyway. The ET starts when your front tires clear the staged (2nd) beam.

It could be argued that there is a connection to RT and ET with regard to staging. If you shallow stage (barely turn on the staged light), you'll have more "roll-out" before the timer starts than you would if you "deep stage" (turn off the pre-staged light but not the staged light). So, your RT would be longer with shallow staging but ET would be lower because you're moving faster with the extra roll-out by the time the timer starts.

To further make the point, there are father/son racers at the track that both run the same car, a '57 Nomad. The dad deep stages to try to get a better reaction time, while the son shallow stages. The son always dials quicker, even though they use the same shift point, stall up the same, etc., and the son out-weighs his dad by about 40 pounds (neither of them is "little"). All other things being equal, the son should be slower when he runs, but that isn't the case because of the differences in staging.

She's almost done... so stay tuned.

Other: This car is a full weight daily driver. It's gone more in it. I'll wait until it cools down then remember to adjust my pinion angle so I don't spin so bad.

G8: Don't remember all the stats, but bone stock, M6, on all season tires it ran an 8.7. The thing is very prone to wheel hop so i had to leave off idle.

Last year I was a few seconds quicker, I didn't think the air was that bad in Calgary? You guys are putting down some pretty awsome times!!! I think I might take it in for a tune-up in the spring...




Just kidding guys, it is good to see other cars to compare with. Keep the Lt1's and LS1's alive!!!
I havn't run at the track in my car yet. All stock internals with bolt-ons. Planning a build, hope to put down similiar times as you guys by spring.:LS1LT1flag:

My two LS Camaros, mods in sig, at 5800' elevation Bandimere Speedway, this past Friday.

'82 Berlinetta with 2000 LS1/4L60E (my son, who is about 60 lbs lighter than me, was driving the car that night):

60' --- 1.791
330' -- 5.299
1/8 --- 8.212
MPH -- 84.53
1000' - 10.373
1/4 --- 12.874
MPH -- 106.0
DA --- 8444'
Wind -- 2 mph head

'82 Berlinetta with 2000 SS LS1/T56 (same day, had to run skinny DOT slicks for the class that was being run that day):

60' --- 1.869
330' -- 5.473
1/8 --- 8.456
MPH -- 83.04
1000' - 11.011
1/4 --- 13.164
MPH -- 104.38 (was hitting the rev limiter - tuning issue yet to be resolved; not a problem with my "regular" slicks)
DA --- 8355'
Wind -- 5 mph head

Guess I haven't updated mine.

'82 Berlinetta, ~3400 lbs going down the track, at Heartland Park Topeka last September, ran a 11.95 @ 114 mph, DA ~2000' with a 9 mph tailwind. With no wind and DA a little higher later in the weekend, was running 12.0's.

This spring, was hoping to get the '57 running in time for the season, but not there yet. Want to run a class here that requires a 12.75 or quicker ET. So, I took out the passenger and rear seats, spare tire and jack, got the weight down to 3305 lbs with about 10 gallons in the tank. Last Friday, ran a 12.61 @ 108 mph with DA of 7200'. The first race requiring the 12.75 is this coming Sunday, hope to get the gas burned down a little so the weight will be down a little more. Hope the weather/DA cooperates...
