Default Does this seem slow to you?

Well I took her out to the track last night... Southwestern International Raceway in Tucson, AZ. It was a great night for a Test n Tune. I got 16 runs in which is amazing. Even if I was there from 5PM to 11:30PM.

Here is my best slip.. I think I should be fast but I just couldnt get any better at all. I started in the 16s and brought her down to a consistent mid 15.

What do you guys think? Is there something wrong with it?

well, its getting cold outside again...****in reached down to the 40s the other day.  almost can't wait for the snowy stuff............................almost i don't have a twitter account nor have i ever been to a twitter web page (update: i have), but if i ever did decide to take the plunge i will let you know by posting it in this awesome little box of text (update: not really)! i like tacos lol...though between crunchy tacos and soft tacos i cannot really say which one is better.  sometimes, the mess a crunchy taco leaves behind is a little annoying while the soft taco just doesn't have the same taste... cake is so much better than pie no, srsly.  **** pie. ****ing

I think that's on the slower side but that track's elevation is a big part. Your 60 ft time is not good. What tires are you using? For your launch did you stall up to 2600 and leave from there?

Street Tires... 245/50R16s An all season with good tread depth. I kept them at street pressure because I didnt have a pump and I was launching between 2600-3000 with the brake mashed... They were weak launches and it took forever to hit the power band.

3.27 gears and the .747 reaction time are killing your 60ft time. Some 3.73 or 4.10 gears would put you into the power a lot faster. With auto trans 4.10 gears would be great for you .

Well the reaction time has NOTHING to do with my times when I am just doing a Test and Tune. I sit at the light for a long time sometimes to get a good launch. I agree with the gearing though.

I thought you would have been in the low 14's/high 13's with that setup. First thing I noticed in that list was the gearing like everyone has said. Has the car been tuned? What's the car weigh? The heads are definitely killing potential.

As a side note, that's a clean looking car.

I was hoping for 14s because of the altitude for sure, but not having a hard time doing 15s!

Yes gearing is 3.27 I was told, so that hurts for sure but is fantastic on the highway.

I do not know if the car has been tuned or not. I would assume so.

Car weighs 3538 with my big butt in it.

Yeah, new heads would be nice to help her breathe.

And thank you! I just bought her on Thursday and I am very happy so far.

I also race that strip, have for years.
That 4500+ air density isn't helping things at all, niether are those gears and the car wieght.
NHRA used to correct.25 to sea level from Tucson so you would have run a 15.21 or something like that last night.
I would take a long look at all the systems on the car as it seems very pokey to me......

I think most of it is the 3.27 gearing and the 2600 stall. I am slow off the line hardcore. But she shifts solid and pulls hard from 3500-6000.

I think it should be in the high 13's at the least. When I first got my car it went 14.5@96 with stock heads and cam, 2.73's, crappy street tires and didn't have a good tune up done
