Sig fixed. Put the XB back on top, as it's the right car for the forum I know everything there is to know about Camaros, I know nothing about the Box-mobile. Thx for compliment, Brian.. Now we gotta get these things faster, and more cruise-able!

Someone in Socal has a Starlet motor in his xB. I'm not sure but I
think it runs somewhere in the 14s. Wish I had more info on it, but I heard
about it at a meet a couple months ago.

whats funny is, people have always acted like autos are sooooo slow..yet unless your doing a straight 1/4 run auto vs. stick you cant hardly tell...

in the past they were not as well designed so it was noticeable, but these days its hardly noticeable

i'll have to test that vs. someone with a setup close to mine. Maybe Matt from Style bB he has I/H/E like i do ...his box is fairly quick i think

i have nothing against automatic, but when a supercharge an automatic xB and it runs a 1/4 mile run in the 17's, then you start to wonder....

killer thats exactly what im saying lol the autos are designed quite well in the Scions it seems, my box is pretty peppy i think..in fact it has more pull than my old 2000 corolla which had listed 125hp on it..i doubt it got exactly that but it was a peppy little car....this box pulls harder

Automatics have gotten way better over the years and they do offer some advantages over manual. A well designed toqure converter can actually improve performance. Depends on the design and how it's been modified.

Since this is a dragging thread, I will also mention that autos can be much better suited for the drag strip than a manual. The issue is getting the auto to shift optimally and quickly for acceleration rather than fuel economy and long term reliability. A friend of mine had his Mustang's auto modified for hard shifting to improve acceleration. But, then, his transmission blew when another friend was driving it somewhere for him!

I do not know what is the most common in profession drag racing, but autos and clutchless systems are used.

If what killerxromances is saying about his time is true, then those FI autos running 17's were probably not set up well at all. I have seen him in other threads and he seems okay. But then maybe I am not :D

Dragging ain't my thing anyway.

I love my five speed!

I seem okay huh? jk.

Keep in mind, 16.4 is my best time, not my average time. I also my point out, in order for me to get 16.4 i also had to take out the rear seats, brackets as well as spare tire and all of that. Makes a difference. With everything in the back, i usually do around 16.6-16.8. 17+ is way too slow for f/i people, somethings wrong if you have 20whp above what i have and you still can't touch 16's. lol

Drag isn't my thing either, i've only been to the drag track three times since i have had my xb. I'm more into auto-x/street course. I miss my manual trans though. Automatics have its strong points and weak points. Too bad the wait for a manual was two months when i bought my box.

But out of three times going, i've done a total of seven runs.
Here are all the results:
16.4 @ 83mph
16.6 @ 80.mph
16.9 @ 78.9mph
16.6 @ 80.6mph
16.5 @ 82mph
-----------------
Results prior to header and different exhaust set up:
16.9 @ 78mph
17.2 @ 76.7mph

^^^^^I retract my previous comment.... 16.4 is hella nice bro. Mad props, to you! I still havent taken mine down to the strip but ihope its somewhere in that vicinity and if you running automatic you must have a few tricks up your sleeve, or are you just running bolt ons?

haha, well, i prefer to understate, i don't know much about you, and the other two seemed to find you questionable :/

to further jack this thread, i think that it is possible to tune an auto to shift for power rather than economy.

good luck with the xA and xB dragging.

I know what you mean, everybody lies the only question is about what. Its human nature, but i can ensure you i'm not lying about this. Theres no reason, 16.4 as a best time is still slow. Then again, i'm more set up for cornering than drag. I love light weight cars, you get just enough go and the right suspension set up and you can have fun. By no means, is the xb a drag queen without thousands dumped for a custom swap.

I'm just running bolt ons, i'm mostly set up for autox/cornering. What mods do you have? I was dyno'd at 96whp @ 4,600rpm. So i'm nothing special, its all about knowing how the car reacts to shift points, and with that said knowing when to shift. When i go to the tracks, 1/4 or usually autox, i disable trac control, o/d and manually shift. I miss manuals, i might be selling the box in the spring for a 5spd yaris.

Like i said, removing the back seat, brackets and spare tire and such i was able to go from an average of mid-high 16's to breaking almost low 16's. Its not impossible, look at hotbox05. Hes pretty much running stictly bolt ons with weight reduction as well, hes pulling high 15's in the 1/4 with probably low 16's average. Thats on a manual.

Let us know when you go and what times you can pull. Most i/h/e xb/xa's that i have seen run a constant low 17's, some break 16's. Then again, most aren't dragging the xb or xa. Infact, most are only doing show. In my opinion, if you keep building the 1nz build the car for cornering. It's much fun-er than 1/4 if you ask me.

I completly agree!!!! These cars are NOT made for speed, but DDDAAAMMMMM can they handle, with a few suspension coomponents (more coming in) make it a perfectly balanced car. Thats ffunny that you mention circuit racing because i just happened to FINALLY be able to race my xA. Here are some pictures:

Yeah, handling is great! With each suspension mod it gets better and better!

I'd like to hear about JSosa's results too, but maybe a different thread? This one is for dragging after all. Please post a link if you start another.
