That's no excuse brother it's a 16+ hour drive for me the only difference is my mother-in law already hates me.

 

That's dedication to the sport. Enzom- are you listening?

 

Thanks Enzom,

I willl check


Here is your 3 runs under FULL correction , your SC requires me to do more work but you can see they correction factor is only as good as the data you input. Your DA is slightly different but it is negligible. I previously corrected your slip and it matches up nicely with these runs, you have some consitant times so this actually is a great tool for you to measure which run is best as if they all happened same time same day same car same driver. Only you know what was diffferent about your car, fuel,tires,weight, modes..


here are the three runs the results are linear and the correction is very minute.

slip 1
The closest weather results for 11/17/2006 at 02:10 pm

Time recorded 1:54 PM
Temperature °F 62.1
Dew Point °F 41.0
Altimeter Setting 29.77 Inches Mercury
Absolute Pressure: 29.74 Inches
Density Altitude: 535.5 feet
Track Elelvation: 33 feet

UnCorrected ET:
11.901 (sec) @ 117.23 (MPH)


Corrected ET to Sea Level:
11.834 (sec) @ 117.905 (MPH)

I checked weather on both sides of the slip and DA was dropping in the area from 1pm-3pm, so the 778 reading differs . We can use that # if you prefer or I can convert this run to 778?

Run #2


The closest weather results for 11/17/2006 at 02:02 pm

Time recorded 1:54 PM
Temperature °F 62.1
Dew Point °F 41.0
Altimeter Setting 29.77 Inches Mercury
Absolute Pressure: 29.74 Inches
Density Altitude: 535.5 feet
Track Elelvation: 33 feet

UnCorrected ET:
11.904 (sec) @ 117.01 (MPH)BEST ET

Corrected ET to Sea Level:
11.837 (sec) @ 117.684 (MPH)

The runs are so close together that you likely just correct the best run and compare that to the run that occured on a different day or hours prior or after. You only need to do this if the DA has changed by a margin of significance.

Run #3


The closest weather results for 11/17/2006 at 01:16 pm

Time recorded 12:54 PM
Temperature °F 62.1
Dew Point °F 41.0
Altimeter Setting 29.76 Inches Mercury
Absolute Pressure: 29.73 Inches
Density Altitude: 546.9 feet
Track Elelvation: 33 feet

UnCorrected ET:
11.913 (sec) @ 117.59 (MPH)


Corrected ET to Sea Level:
11.845 (sec) @ 118.281 (MPH BEST TRAP SPEED

So you have essentially the same DA on this day on all three of your runs comparing all three lets correct the best run and take it down to the negative DA say of -1000 and see what your car would have done had it run

http://www.dragtimes.com/2005-Merced...ecs-11697.html

I previously corrected this time so I will use the full correction so our data is consistant. If we want more precise #s we must take .50 of the correction factor, but taking 100% will still show you which run is FASTEST if all the runs happened at zero feet.

Here is your run from March 31st, the weather info is printed on the slip

Here is where the comparison gets interesting..
We now have all the runs at SAE zero feet.

Your runs at ATCO are better lets take your best run and see what you would have done at Englishtown at -1000 DA.

Here is your run from ATCO
UnCorrected ET:
11.901 (sec) @ 117.23 (MPH)
Im going to take it down to -1000 DA or more specifically -1054 the same DA you had on March 31st 2007





E.T. 11.901 (sec)
Trap Speed 117.23 (mph)
Measured DA 535.5 (feet)

--------------------------------------------------------------------------------
Corrected to -1054(feet) DA
Corrected ET 11.704 (sec)
Corrected Trap Speed 119.256 (mph)


Your runs at ATCO were stronger than your runs at Englishtown, only you know what was different about the car, maybe you just drove better.(60 ft times were better) This is absolute fact, not speculation, the numbers came from your slips and were simply all converted to the same standard(0 feet) geopotential altitude. I took all your runs and put them on the same track same day same driver same car.his is merely one more tool you can use to compare your runs on different times, different days , different tracks.

I could put your times at any standard the calculation is composed of known constants in the atmosphere. I could take all your runs and put them at 5000 feet, whatever. I use this to compare my runs to others.

You have a fast car and your runs are very consistant. Your car will run sub 12 seconds in conditions under 1000 ft. So a DA over 1000 ft would IMO be a necessary notation. Obviously IMO a negative DA should also be noted because the "fast time" was aided by atmospheric condition" more than ecu tune , traction, etc.. Your driving was better at ATCO by a slight margin, it was the "great air" that got you the 11.85

You are correct this is less accurate as a prediction of future runs, it is only accurate 100% at taking several runs and putting them at zero feet. certainly does not mean you will ever run what the calc says. BUT it does tell you with 100% certainty which run is faster when placed at a standard.

The weather info you question is printed on your timeslip? You have a recorded barometric pressure and temp and it matches my calculator so the DA at englishtown as measured from your slip was 900-1100 feet below sea level.This would have been the 1 hour previous to your run and one hour after. The Air on March 31 2007 never got to 200ft it was negative the entire day by 900-1100 feet. Temp was 46-51 degrees and would have to of gotten to 62 on the track , its more likely that who ever told you 200 ft had a bad reading. Unless the temp at the track was 12 degrees higher than the weather station. Best ET uncorrected and corrected,

You had a higher trap on the other run,
better ET on this one

Man you have a fast flippin car

to me your best run is at Atco
UnCorrected ET:
11.904 (sec) @ 117.01 (MPH)

And is truly AMAZING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! stock this BLOWS my
mind.

 

Sacramento raceway is closed for any private event this year.

On Saturday, it's $5000 to rent the track + expenses.


On Sunday, it's $3500 to rent the track + expenses.

Jennifer has kindly suggested that those interested in running should participate in the CMI sport Compacts September 30th or January 13th 2008. Cost is much cheaper because CMI pays all track rental and expenses.

According to her,
"Your group would just pay the $45 race fee or $10 spectator fee and CMI provides you with your own lane of racing so you can race just your group."

Hope this helps.

While you wait for 300+ Hondas trying to figure out how to line up,do a burn out and then break the tranny 5ft out...then wait for a tow off the track and thats only if they havent oiled down the entire lane first! Uh,no thanks on the import days.Plus I cant understand what they're saying half the time anyway...lol

3500 for a Sunday isnt bad! Get 15-20 people and split the cost,Im ready for that.Track all to yourself and no fart can noise,sounds good to me.

 

Cool! I just got an e-mail confirming 20 spots still open and they are indeed running both lanes.

 

It's $3500 + expenses.......

Here's what she said

 

TED BALDWIN

You have been critical of the correction, noting DA from the beginning. You have never truly offered anything of substance to the argument against.

You run what you run, man I hope next time I go to SAC i have a tail wind and a -1000 ft DA, I will run a 12.1 and you will see no talk of DA. Comon guy seriously , ok now comeback with the runner stuff , Hey does that DA look familiar?

Funny your only slip on dragtimes shows your car blistering down the 1/4 mile in 11.9 @116.X, I know why you do not correct or mention DA easier to just list slips of fast runs. What was the DA during your run in November 2005 at 11:36 PM at the Atlanta Dragway?

This is where my correction calc comes from, read it maybe you will better understand the calculation, I suppose this is witch craft?

+1 go Juicee go

 

OK IM IN!!!!!!! Lets go Mr. Rocket.

MBFOREVER?

SAM?

 

You already sign up and pay? You 100% going?

 

yep, paid and emailed em deets..

This is a great track but 850 feet, we need 60 degrees 8am run!!

Lotsa mustangs, you can take down the Z and let me handle the Camaros

 

Actually its a little over 1100ft...1121 to be exact and you'll swear it looks like it runs way up hill.The track officials say no,but we checked it with a hand held gps and it does indeed run up hill.

Now that I think about it we checked and it was 1154ft or so.

 

Oh good we can test our NEW WEATHERSTATION.

oh well , more corrected times

Traction? this should be better than LACR?

 

Josh u driving to MIR??

 

Yes this track does hook better than LACR.One good thing is the amount of cars attending and we get both lanes to run.Im predicting some fast cars to be there,meaning big tire cars and alot of vht and rubber to be laid down.We need cool temps,warm track surface to the 330 mark and no wind!

 

No,he talking about his deal I just found...

http://alternativemotoring.com/index.html

 

Dam I want to go so bad...cannot really get away for long enough..But I will be attending SACRAMENTO soon to race my favorite modded E55 hey wheres Denny's LOL

 

Thanks for the info John.


We are heading up this friday for test and tune. Care to join us? Why don't we tune your car real quick?

 

Friday evening? anything on Sat?

hmmmmmm tempting but I think I gotta work.

 

Josh? You Work? I see you 24/7 here?

 

work is over rated bro!
come on im gonna run on my street tires. should be easy for you to put another voodoo hex on my car and smoke me.

adam any word on the wireing? send me the instructions and ill have it done before friday.

 

you selling your light rims.......

hows the weather up there ..man we gotta do this again soooooon,

 

lol

come to cali bro......that would b serious

 

yes i think i am! i like speed but just not as much as you and others. i have to have a lil bling in my cars. its slow *** 20s for me but i will look good loosing to faster cars with lighter rims.lol.

weater was crazy hot last week 105 but this week it is already cool by 7oclock we wont have no 60s this week but we will have mid 70s
