First 1/4 mile outing. Very Humbling...
 

Hey all. Let me start out by saying that ive never raced the 1/4 mile before. Don't rag on me too bad. First run, no traction through first gear. Ran a 14.2 with a trap speed of 103... Second run was an even worse 14.4 with a slightly higher trap speed... Now this is where it gets interesting. I started hitting my starts pretty well, but kept on missing 4th gear... Did a 13.978 at 96.89 MPH, and my best run was 13.5, which i also missed 4th gear. My trap speed on my best run was only 88 MPH... Is there any way to guesstimate what my my run might have been on my 13.5 had i not missed 4th gear? I mean once i missed it i just coasted across the line basically. I got on the scale, and with the spare removed and the the extra **** gone and a 1/4 tank of gas and me in the car it weighed 3450 (i weigh about 165). I just think its nuts running a 13.5 at 88 MPH... Thoughts? And yes, I have my slips

have no idea, but coasting from missing fourth and still hitting 13.5 seems, well weird. you're only option, not miss 4th and see what you run....

1/4 Mile ET 1/8 Mile ET

Enter the � Mile ET or the 1/8 Mile ET and
Click on Calculate...
� Mile ET = (1/8 Mile ET + .22) / .655
1/8 Mile ET = (� Mile ET * .655) - .22

How do you miss 4th gear?

X2.. If I miss a gear it's usually 3rd.

I don't know. Its never happened before, but I did it twice... Its scary putting it into second and fishtailing everywhere...

NERVES...that's how!!!

You will get beter with time.
and when you run the car, never look at the car beside you till you finnish your run

Very true, that's what seems to mess me up I tend to want to focus on car I'm racing.

Just hit the gas and go straight

I have to think that the one with the lowest ET and lowest trap speed has to be error on the part of the timing gear.

Thats what i thought too, but i was not that far behind the guy that ran 12.0 against me that run. Compairing my 1000' to the other run that that my trap was 96.89 my 1000' was almost a second faster with the 1/4 trap being 88 mph. Also my 1/8 was a second faster aswell. My other "good" run was a 13.978 with a trap speed of 96.89. Which I also missed 4th... Really itching to get back there. From what some other guys were telling me, having a good ET comes down to having a sub 2 second 60'

What was your mph at the 1/8?

your trap only being 88mph just sounds so weird lol glad to see you finally went out to the drag strip.

my first time at one with the Z wasnt too special either. best run then was a 13.3

then ran some more got practice in and dropped to a 13.1 still only with exhaust and a full tank of gas

added intakes and a tune and dropped to a 12.899 @ 110.7 with me being 175lbs and a almost full tank of gas.

keep practicing it'll get better each time well it should lol

84.10 I def hit faster than 88 mph. Just shifting into second from a tacked out 3rd gear tends to slow you down a lot. scared the **** out of me

Well guys im off the the track this sunday. could be the last N/A run for the Z.
its going to be 52 degrees F. The track should be better that opening day.
have been driving the car all week and it runs like crap.
I may run the cobb set up for one pass if i can not make the uprev work.
Have to find a way to get rid of the bog off the line at 2200 rpm !

Z

Good luck man! I'm really hoping to get out there again this weekend

You're lucky you didn't turn your motor to scrap. A rev limiter can't help you when you go to the red line in 3rd, then hit 2nd instead of 4th. This will force the engine way past the red line. Do your best to make sure you don't do it again. Just trying to save you from disaster. ;)

Also, your time slip is correct. Most of your ET comes from the first part of your pass. If you shut off a little early but still cross the finish line with any reasonable speed it won't hurt your ET as much as you'd think.

Any way to guess what it might have been had I not missed 4th?

Since the first half of your pass was good the easiest guess would probably be to use the suggestion on post number 3 on this thread (1/8 th mile to 1/4 mile conversion).

here alex i found my slip pic from the 1/4 mile times thread. just so you can see some stuff make compare or whatever you wanna take from it. obviously on the right lol

Thanks for posting! It helps a lot. Im starting to realize that the starts are very important. Our 1/8 mile speed was almost identicle!

yea but i kinda let go worrying about speeds since i ran a 12.900 right after my 12.899 and the speed difference was like 5mph slower. i think the .899 was 110.74 and the .900 was 106 or maybe 105? i got the slip somewhere at home.

oooo i just read the top of your slip and saw it was the import faceoff. how was that? i'm doing the one close to me june 30th. still cant decide on what class i want to run though

But your 60ft and 1/8th ETs are not. He has a much better 60ft time. Your car has the power to get it done (indicated by your mph), you've just gotta get it to the ground.

Run time trial. I did all motor sport and I was the slowest car... they were all running low 12's high 11's.

i was gonna do sport and/or bracket class. i know i can keep pretty consistent times. that is if they let me run 2 classes.

I was going to bracket, but since it was my fist time i figured i would be pretty inconsistent. If you get eliminated, you can always switch to time trial so you can still run. Did you mess with tire pressure at all? I actually checked mine at the gas station on the way home and they are like 42-42 psi... lol

i like bracket racing. as long as i get 2 good practice/qualifying runs in to get a solid idea of track conditions and where my times are at i can set a pretty solid dial in for myself.

my tire pressure is just what is recommended at 35psi. i'm not sure if it would be better or worse to lower it since they are pretty low profile (stock size tires).

people have told me to try it but i just havent felt a need to yet.

I thought about trying 30 and see if i notice a difference

at PRP i may try it since they have air right there on site.

Do they have a scale too? I was shocked when I got on it at the track. 3450 with me in it, 1/4 tank of gas, and the sub, spare, and jack removed.

no idea. i have all my stuff still in my car and usually go with a full tank to the track, and i weigh 170-175 depending on the day lol
