Calipers is spelled wrong in your Sig.

I'm not sure what kind of times that car CAN run at that Altitude. But... good job, I suppose. The MPH looks good. Just make sure that if you run into wheel hop, that you let out of the gas. DON'T try and muscle through it. You'll damage the hell out of your car.

When you launch off the line. Ease into the throttle... don't give her 100% throttle right when the last yellow flashes. Hold 2k, then slip the clutch out and ease into the throttle.

 

Im gonna assume your just being sarcastic.
i sure hope so.



matt if the weather is good we can probably work on your tune on the weekend.

 

what? are you serious? You can't honestly think that altitude and air density has anything to do with your e.t.'s, it affects your power output. OBVIOUSLY his power output wasn't the problem that night, hence his 100mph trap speed.

You guys must be french canadians, that's why you are all glorifying such awesome track times.

 

you realise you just said that power output has nothing to do with ET.

1, your an idiot.
2, your a bigoted idiot for your second comment.
3, none of us "glorified" anything. we said it was respectable, you said it was the "worst time ever",

go and do a little research on drag racing and DA, before you make more of a fool of yourself than you already have.

 

no, I said that DA wasn't effecting your boy since he was trapping high enough to run much better times.

DA does effect your power output, which in turn will effect your e.t. BUT, DA has nothing to do with your e.t. if you are trapping the same speed.

For instance, say you go to a track that is 700ft. elevation, you trap 100mph.
Then you go to a different track that is 2300 ft. and trap 100mph.
If traction/driving is the same, then you should run the same time, you WON'T run slower just because the altitude is higher.

I was trying to reframe from name calling, but since you started it, Your the idiot. Get out of here with that weak slow stuff.

 

thats wonderful
except for one thing.
if your trapping 100mph at 700ft, you WONT trap 100mph at 2300ft

what now?

 

I got nothing, I was just giving an example.

 

pwned... atta boy anom

 

heres a little math for you
14.9@100mph at 2500ft altitude (were at about 2300, but the DA is almost always above that, usually over 3000)

Correction factors:
ET: 0.97
MPH: 1.03

14.4@103mph

Still shows that driving needs improvement, which we have all already agreed apon.
but suddenly 14.4 doesnt really look to bad for just a catback, in slick conditions does it?

 

no, but it does look bad for 103mph traps. We are still where we started. Plus let's not start with correction factors, you don't want to see my run corrected. LOL. It would put the top 8 on the top 10 list to shame.

 

but theyre not talking about you

 

no were not back where we started. we all agreed that his driving needs work.
but you said his time was quite possibly the worst ever.

14.4 with just a catback is quite respectable.
especially on a first visit to the track.
many people dont run this at sealevel even with stage 2

google says Omaha is at about 1000ft which barely registers.
its worth about 1/10th and 1mph

 

I raced in KCIR. There is no 1/4 here. KCIR is 700ft. And the DA was higher than that on that day. Next to a river.

anyways, he didn't do a 14.4, so quit changing the numbers, he went 14.9@100, which sucks. I know it was his first time, but like I said, let off the gas a little and he'll do much better. My first run stock was a 14.8.....at 94, but that's me.

 

wow.

your a perfect example of what i said earlier in the post.
people at good altitudes have no clue about DA, and think its just an excuse.

One day in the future when you actually find out the truth, i hope you think back on this.
have a nice day.

 

you got to be kidding me. Remember I went 94mph bone stock! Most people trap a little higher than that. I know all about DA. I was pissed that my car trapped that low stock.

 

no.....no you dont

 

Did I tell you I love you, lol jk/jk

altitude does affect your time, here is the list for altitude corrections via the nhra!!! why would they have this list if it wasnt true....

Here is the NHRA altitude correction table.

I think what rallyartist is trying to say, is that since he's trapping 100mph... he should be running low 14's/high 13's... because that's what a 100mph trapping Cobalt should/can run. That guy is nearly 1 second off pace.

IF the car were to trap 100mph in denver running a 14.0...

and then IF (we know it SHOULDN'T happen) BUT IF, it were to then trap 100mph at sealevel... the times SHOULD be the same. We all know that once he comes down to sealevel, the mph SHOULD raise, and the ET SHOULD go down. But he is saying IF.

Summary:

With a 100mph trap... a 14.9 is ****.





PS: My first trip down a 1/4 mile track EVER... was a 14.1 @ like 103mph. I beat an SRT4. I have video!

 

thank you. I'm glad someone agrees with me.

 

Try some prothane tranny mounts, and the TTR upper engine mount should reduce some wheel hop for ya. I know it did for me

 

no, you are both misunderstanding where i took exception to his comment.
as ive said about 5 times in this thread, the track was glass, he is new to the track.
we established many times that his driving can use improvement.

I took exception to the comment "quite possibly the worst time ever"
its NOT, and as ive shown, his run would be equivalent to a 14.4 at sealevel,
which we all know, would be a quite respectable time with just a catback.

sure, with a 103 mile trap, it would still show driving error, but its STILL a respectable time.
which is what 99% of the people in this thread have said.
except for ralli, who came in the thread with a cocky ascerbic attitude, and an unnecessary comment.

Dont confuse my comments to mean that 14.9@100 is showing good driving, i never once implied that.
but it is far from a terrible time, considering altitude, experience, and track conditions.

 

I'm not misunderstanding you. I'm just saying. All your points are valid and true... from certain perspectives (Throw in some variables... and they start changing things). Bad track prep or not... the time isn't THAT great. Decent, I've seen FAR worse out of SS/SC drivers (17's - FAIL; 15's from a Stg 2 - FAIL; etc etc etc). I've ran **** times too... I'm sure we all have. And NO... at sealevel, he wouldn't necessarily have a better ET. Quite possibly, he'd have worse... from being at sealevel and having more power, he might spin a whole lot more. I've seen people that ran mid 14's stock... they put Stg2 on and ran low 15's. Driver skill is huge... and bad track prep or not... his is shown in the time. When the prep is bad... it all becomes about throttle control. That'll come in time with track experience though.

And of course, if he DID start to run better times... that Trap Speed will drop as well. But I'm sure you already know that.

 

ah, its refreshing to disagree with someone who actually has a clue what their talking about, instead of just saying "you suck, your run was crap"
I agree with what your saying for the most part.
except that when prep is bad, throttle control can only help so much too.
I had slicks on and had spun nearly all of second.
which is also what made the runs appear like bad driving.

example, last year I routinely run 2.1 60fts on street tires, and ran 13.6@102
i have decent abilities on the peddles.

but friday, I ran low 14s at 103 3 times in a row and then parked the car.
the track was very poor.

 

True I suppose... I do remember just giving up on one pass, because 2nd just WOULD NOT grip.

 

Coming from 1/4 mile runs last summer up here in Denver at 5k+ feet (and 8k+ DA on a really hot-ass day), I thought I'd chime in a bit. An0m is spot-on.

OP, good first time out. Traction is a bitch and a half after a good snow. Bandimere here in CO has the same problem, although track prep is a bit better there than I hear yours was.

17's are still fail up here, but 15's... eh.

On a hot day up here at Bandimere, during the summer, 15 flat out of a S2 isn't fail, There's a guy up here with S2/2.9/tune/traction mods that runs mid 14's (ain't a bad driver either). Hell, my brother-in-law's STi ran high 13's all day last summer. He's not the best driver out there, but you can sure as hell bet he walked my car.

If that's not an indication that DA (and by extension, heat) hurts times, I don't know what is.
