anytime you're at a sea level track and have temps below 55 and barometer readings over 30.40...you have damn good drag racing weather. But remember, there does come a point of diminishing returns if it gets too cold.

the ideal scenario IMO, is something like 45-50 degrees, 30.60+ barom reading....and a sun baked track. That same weather scenario on a track at 9pm is probably flat out dangerous. Power producing air quality is one thing, traction capability is another. Thats why you see lots of records on a track rental DAY event.....not a friday night test n tune with 100s of fwd cars rolling through water

 

very true

 

OK ! no mater the date or the elevation, mt.holly is 21 miles away i just map quested directions for the distance, that elevation of mt.holly and its geographic location in that part of the state next to the rancocas river and near the Delaware and the Atlantic to the east has a diferent weather then atco being more center of the peninsula of south jersey, but either way your more then welcome to come to atco and try, but you keep picking Mir, and predicting our weather, when a racing weather station was at the track surface, in the shade being used to set yo-el car up for the cc challenge, i doubt he is putting in false info to dial hes car in, he is a very good drag racer, also i have used the crappy drag times calculator and found misinformation of elevation on some tracks, but i have also entered the info, went back to double check the info again with the same info, and got a different da, but either way i got the slip the video and my names on the list #1 and if you correct the times with your phony da readings I'm still #1, if you correct all times its still #1, stop crying and beat it, if you spend less time crying about how unfair it is you could advance to the top. stop making excuses if i lived there or if i was at atco

 

?????? Sorry you feel that way, nobody was attempting to infer that your 10.62 time, time slip or video was wrong...the whole world knows your #1. I just questioned your given DA number, that's all. Pardon me. Its no secret to anyone (except perhaps to those who run reguarly at Atco ) the best negative DA is at Atco and Mir...which is why I took a holy grail trip down there myself to pick up .30 at -1552 DA!

 

Well in all fairness, MIR is home track for two of the better drivers you will find anywhere.

Jamie Furman who has run 10s in both the bone stock on runflats Z06 and the bone stock in a convertible Viper.

And of course Ranger.

 

True...nobody is disputing that. You might even say "best". In fact, Ranger was running my rental at MIR. Great guy. Though even Jamie and Ranger know the benefits of running in deep negative DA and the amazing effect it has on ET.

 

Ok Bro Listen I was at ATCO yesterday with a weather station 25 feet from the burnout box -400 most of the afternoon. Drag times says it was -1200 NOT EVEN CLOSE Keep spinning the wheel of excuses

 

i was very disappointed with the track da compared to the online calculator predictions, the car was put in the garage and not driven more then 5 miles since the last dec rental, so if the air was better the car should have ran faster, as to your own words every 800 ft of da is worth a 1/10th i think you say. i was hoping for 10.42 it didn't happen, if the air was better then last time like you say it would have been 10.4s, with the air and tire and rim change we couldn't even run the 10.69, and should have been faster with my different wheel and tire combination, which it wasn't, you can clearly see the 60 ft was better, but the air wasn't. if the air was we would have been able to run the 10.69 easy but 10.74 was the best 3 of them with 1.441 60 fts, the 60 ft on the 10.69 run was a 1.437 very close but a slower time with your so called better air the air was gone it wasn't the same at the track as your 20 mile away weather stations in the shade, atco has a 1/4 square mile of asphalt the temp on the track on a sunny day is much higher, you might have read a book of instructions on your weather station and seen some calculators online and think you know what your doing, but i will go by my experience and yo-el's knowledge on the da, he said the da was in the -400 range Tommyd noted it, thats all i need to be fact and my own personal experience as to being able to predict the times i will run with weather. and knowing enough old school knowledge to get the record run when the weather isn't cooperating

 

It's a shame that all tracks don't have a weather station with the sensors located at mid-track. Then they could have timeslips with actual times and DA adjusted times. If they all used the same adjustment formula it would allow any car at any track under any conditions to have equalized comparitive information.

I just don't get very enthused to run in Phoenix with a 5000' DA in the summer and get handed a timeslip .60 slower than my PB.

Of course, the tracks that commonly have low or negative DA and the manufacturers of the handhelds would lobby against it.

 

Apparently it is a secret.
That's quite a bold statement and obviously one being stated by a person who has never been to No Problem Raceway, Houston Raceway Park, Sacramento Raceway or even my local track Raceway Park.
I'm not sure if it's pure ignorance or just plain ol' stupidity that would possess one to actually make such a statement.

 

Exactly.

Ellis ('YO-EL') doesn't fool around when it comes to racing in the Corvette Challenge Pro 11.50 Index races at Englishtown throughout the year. The competition there is fierce and there are a few guys that rely heavily on the extreme accuracy of their weather stations to actually adjust their throttle opening/percentages via EFI Live to slow their normally mid 10 second cars down to run 11.50 on the dot. Even though it was a track rental in good air, he wasn't going for a new best at all and was actually intentionally trying to slow his car down...and I can assure you that he did not enter his base data incorrectly.
Yes it was a very negative DA in the morning when we arrived...and it was negative 400 when Dennis's car ran it's 10.62.

 

Spoken like a true blue Atco driver. Spare me, oh Atco guy. We both know the deep negative DA days/seasons are far longer at #1Atco and #2 MIR than the occasional cold weather fronts for a few weeks at Houston, Sacramento et al. Ask any fanatical drag racer which track is best for most deep negative deep DA days. Not to mention how many days those other tracks you mentioned get your famed
-2000 to -2500 DA with 32-40* temps and 30.40+ barometer.

 

I have asked them, that's how I know EXACTLY what I'm talking about on the topic.
Houston Raceway Park is a 'near sea level' track that during the winter experiences DAs as low or lower than Atco, and this is EVERY single winter.
Do they get as many as Atco does? No, but they get them regardless and they're also open more total weeks out of the year.






Spoken like a true blue jealous driver.
Spare me, oh 'Atco is the only fast track' guy, you didn't say anything about who has longer days, more days, sunnier days, happy days or even those bloated/less than fresh feeling days LOL.
All you said wasand that is DEAD WRONG. Which also means that you've now cost yourself some credibility for spewing some inaccuracies on this topic and for also, pardon my French, being full of sh|t.

 

Sure Houston is open more weeks than Atco, but it is quite obvious to all, except you perhaps, that Houston has no real fall or winter!
Problem is, the average daily DA is much lower from November thru March at Atco than Houston. Sorry to say, you have now cost yourself some credibility for spewing some inaccuracies on this topic and for also, pardon my English, being full of cr|p too!
