how deep in the 11s
bogging off the line gives you lower than normal mph (to an extent) with higher ET
If he gets the car to hook, he will lose MPH but will get a faster ET. It's just like putting a set of gears in. The MPH goes down, but the ET gets faster.
and no wasn't really a terrible driver... just a terrible setup.

no. trap speed means hardly anything. trap speeds can easily be manipulated by changing gears/different size tires/spinning off the line/bogging off the line.
In this case, he is spinning off the line. When you spin off the line, you gain MPH. That's time slip reading 101.
Now if you want to do a little bench racing... I trapped 93 mph in the time slip I posted. That's without spinning/bogging. So he would be doing 3 mph faster than me @ the 1/8th mile, but would be behind 3/10th's of a second. You figured if he wasn't spinning he'd be trapping like 94 maybe 95 ish (i'm assuming he spun a good bit, because of the 60' time). So he would be 1-2 mph faster than me but would have to make up 3/10th's of a second on the top end. That's a lot of room to close with not a lot of mph to do it with.
and again to prove my point that trap speed means nothing. I've seen cars that trap 122 mph and only run a mid 12 second pass. That's without spinning/bogging.

Spinning a little isn't going to gain you much MPH, sometimes not any. Spinning a lot will likely slow the MPH down and in this guys case it kept him from using the nitrous. So assuming that he runs 96 MPH in the 1/8 spinning bad, he'll likely be even faster should he hook and be able to spray as well.
Nitrous cars, for the most mart are hard to judge 1/8 to 1/4 by ET and MPH, because you don't know when they started spraying, if they let off to shift, etc.. For the most part though, someone who doesn't spray right out of the hole or has to let off due to spinning is going to gain a lot more MPH by the time they get to the 1/4 than someone running the same MPH n/a.
The pass that the OP made would likely be around a 12, but he has the potential for 10s with some traction.
I know what you're saying and you're right to an extent. But when you spin through all of 1st and 2nd gear you're not going to loose mph by hooking up, not when you're spinning that much. And I don't quite agree with the gear swap thing either. I gained mph and got quicker when I put in a 9" w/4.11's and I've seen a bunch of other people gain mph with a gear swap as well, that may not be the norm but I dont think it's a good rule to go by one way or the other.
As far as the gear change thing goes... Think of it this way. When you change your gears, you aren't putting down any more power (for the most part), you are just accelerating quicker. If that makes sense. I can't really think of a better way to word what I'm trying to say, and I'm sure some dimwit will turn it around on me to act like he's got a point to prove. I will see if I can find some old slips of before and after one of my gear changes... But keep in mind, I said GEAR CHANGE. not rear end change. That's kind of like saying "oh I picked up 1.5 seconds on my 1/4 mile time by changing injectors... but while I was changing the injectors, I put in a supercharger(I'm exaggerating of course, but you get the idea)" A new rear end raises a lot of variables (different suspension geometry, new drivetrain loss, weight of car, probably launching harder/higher, etc.)
speak of the devil.. here's that "dimwit" now

we (myself and nnssane02) are both correct and both wrong imo. Most of what he said I do agree with, but it's like trying to figure out what weighs more, an apple or an orange. There's about 8 million different ways to try to guesstimate the time, but only one way to find out.
My car has more MPH when I dead hook. If I spin a little or a lot my MPH is never higher.

He said he was "feathering it", I'm sure he's not spraying while he was off the throttle. He could have feathered it through first and got a 2.0 60' and spun again in 2nd and that wouldn't effect the 60' time at all.
went to a different local 1/8th mile track last night and ran on motor to try and find traction. It hooked a lil better but still spun about 10 feet while digging. The motor was warm and had 1/2 tank of 93 so it still has some on the table. I plan on buying some ET drags next year but I'm just going to finish these ET streets off for now. It ran a 7.7x @ 93mph on a 1.7x 60'. That should definately put me in the 11s but I'm not going to change it until I run the 1/4 in November.
yes I had to run on motor because my dumba*s forgot to check the bottle pressure before I left. I assumed I had 2-3 more passes but it was empty. That run was on 16 psi. in the tires, so maybe if I lower it and Charlotte's 1/4 is prepped good (doubt it), 10.9x on gas might not be out of the question.
this was my 2nd time running the car and @ a different track. I couldn't get traction @ all at the other track especially on juice, so my plan was to find traction on motor 1st anyway...I found enough for a 1.7 and that made all the difference. Had 3 people tell me I pulled the front tires...which I find hard to believe since I don't have skinnys on yet and it didn't dead hook
So you dropped .2 by turning OFF the juice? Don't see that too often
I wasn't far off...I ran an 11.2 @ 125 on a crappy pass...check out the timeslip on the far right. It definately has atleast a 10.9 with better tires.

Very nice man, congrats. That looks similar to my pass the last time I sprayed it, but my 1/8 was quicker (7.0 I think) and the pressure dropped like a rock on the big end so it went 11.1 @ 122. After seeing that slip I have no doubt that car will see 10's once you get it out of the hole a little quicker 
thnx guys...yea the track prep wasn't optimal so I left @ a lower rpm and still spun and had some issues. The bottle pressure wasn't optimal either, so it has quite a bit left. I'd def. like to see some 7.0s...bet you're happy with that
