Times

I'll take a looksy tom. How can an exhaust leak that is BEHIND the front tires smoke the lights though?? I can see smoke off the line blowing over the light with some wind, but to have the wind blow the smoke faster than the truck... Again I'm not trying to be a smart ass I really am wondering.
Because if the smoke is right behind the front tire, the beams can't tell they aren't blocked by a tire until the smoke clears enough to see through it.
Just to add, you typically will only smoke a light if there is a really strong tail wind that blows the smoke forward or you have an exhaust leak at or very near the motor. If you blow a big cloud of smoke on launch, as long as it is at the back of the truck it won't cause problems because it doesn't matter if the beams get blocked by smoke as long as it can see your front tire has cleared it.

I'm still confused/ignorant.
Here is how I would understand the lights, kinda light those garage door lights that keep the door from closing on things. They have a constant aim on on another (or a mirror) and record when there is an obstruction. Right or wrong? comments?
If that is the case than it wouldnt matter when the smoke cleared, just as soon as there was a foreign object in the light path they would record the 60'.
IF you are referring to the staging light had smoke blocking there veiw and finally started time when I got closer to the 60' than the light knew... Than I could see how that could affect the timing. BUT if that were the case than I would have shown it in the reaction time too, correct?

get some slicks on that beast and you will be cutting 1.3s
Can you drop any more weight? That should be enough to get you a 12.
I wouldnt be as concerned about the 60s as I would about the mph.
you really need to log your truck. ( as you allready said )
Yes, it works like the garage door sensors, but it is just the opposite as the way you understand it. When you block the first beam, you light the pre-stage beam. When you block the second beam, you light the stage beam. The timer doesn't start until you clear the stage beam.
I the tail gate off and spare off. I could remove some seats but I really don't think I would want to. Easiest thing to lose weight with is fuel... I ran those on half tank. And I'm having trouble with a $0194 write failure when I try to load pid lists to my v2, otherwise I would have logged them. If I get to run it again this Friday I hope I get the EFI Live figued out by than.
Had a .97 reaction on the 1.498 60' and a .463 reaction on the 1.539 60'.
If you get your tools ready before hand, when you get to the track you can have your back seats and front pass seat out in less than 10 min. I removed my seats, spare and tail gate and ran 1/4 tank of fuel and shaved .2 off my 1/8th.
I would pay good money to see the nuts and bolts flying out of your truck if you can remove them that fast, not to mention the seat parts. :rofl:
I can prep my truck at the track in about 30-40 minutes by myself. After a while, you just get into a rhythm.
Ben, I agree with the others. Something was up with the staging lights/timer. Take a look at the timeslips area. Most trucks comparable to yours are high 1.6-low 1.7 60s.
But so what? Congrats on the runs! 12's will come as you continue to figure your truck out. Keep at it.
I know that, but if the smoke didnt clear it would show a horrible reaction time, thats why I included that. Not that those are great Reaction times by anymeans, there not bad enough to make it think that it blacked out the light comparing with the 60' of each run
Those are pretty shitty reaction times if you ask me, especially the .97, but believe whatever you want. I was just trying to help you figure out why your times aren't right. Did you even look at the video to see the exhaust blowing out from under your truck? I guess you find it easier to believe that everyone here is wrong and your truck can pull 1.4/1.5 60' times on street tires, and that doesn't bother me at all.
Yes I found the leak and fixed it. Just didn't think that little amout of smoke would affect it. clears up fast and isn't thick. They are shitty but I was working on getting my rpms right before I left. Most were about 1 second after the light. When I was trying I got a .007, and two .140s plus a -.030 .. I do appreciate the input whether I'm right or wrong, tough love doesn't bother me atall I'm just stubborn :hug: Hopefully I can get to the track this friday before they close down for the winter.

i think i see where you're confused...
when you take up you are currently blocking the beam. the timer isnt started when you cross the bream the timer is started once the beam has a clear view of the other side (I.e. your tires have moved away). when you smoke the lights it confuses the lingering smoke for your tires still at the line even though you already left. so it says you got to the 60' a lot faster. it aslso explains the terrible reaction times like .9. (yes ben thats bad
) even you you waited to launch till you saw the green you would still most like run a .7 or better. a good RT (in my opinion) for a weekend racer is anything below .150
