    • All dragstrips are not created equal - Why running at ATCO in the winter is basically cheating

      Atco Dragway located in New Jersey is arguably the quickest and fastest strip in the country. Hell, maybe the world. Along with MIR (Maryland International Raceway) these dragstrips are magical places where C6 Z06's run 10's stock and records fall left and right when winter hits.


      Why? Excellent track prep, great location, great weather, and a staff that knows what it is doing.

      When we say great prep we are not exaggerating:



      A launch pad that rips your shoes off is a nice place to get a good 60 foot time, right? They don't skimp on the VHT.

      The prep is one part the weather is the other. You will notice all of these record runs we see have something in common. They take place in the winter.

      What is the density altitude at ATCO as of this writing? -726 feet below sea level. That is what 46 degrees at 8 AM gets you at the ATCO dragstrip.

      -726 isn't even anything special. You can see the density altitude dip well past -2000 feet below sea level.

      How big of an advantage is this? Big. Almost 3/10's of a second and 4 miles per hour of trap speed for a naturally aspirated car breaking into the 10's:


      It varies based on aspiration, modifications, and so forth but you get the idea.

      Based on this information you should now know and be able to tell those people waving fast East Coast slips achieved during the winter as evidence of their cars being faster they they are actually providing evidence of their run conditions being better. Nobody running in Las Vegas or the Middle East is going to be able to compete on a level playing field.

      Quite simply, all dragstrips are not created equal.

        What's funny about it is that these same people will test all year long and not present a single slip until Oct-Nov.

        Just a coincidence... I'm sure.

        You're right but this isn't targeting you... this is a general article on how conditions vary.

        You're taking it personally because you just set a record at ATCO.

        You have completely missed the point of the post. Sticky is trying to say that times from ATCO shouldn't be compared with times from the average strip. This is because ATCO has a documented history of being one of the fastest tracks world wide. That is all @Sticky is saying.

        Exactly.

        If I could I'd run at ATCO too. It's an awesome strip with great prep.

        I'm highlighting that conditions have a huge impact on times and this needs to be taken into account by people more.

        stock 720s goes 9.7 at Atco

        previous boostaddict article of turbo s vs 720s shows stock 720s doing 10.0 in palm beach

        0.3 seconds is about right.....

        Now that Englishtown is closed I'm assuming Atco will be packed...

        I bet this is why west coast shops always post inflated dynos. Cant post a fast slip, so they advertise a higher HP

        Nonsense. Try to run one of your negative DA glory passes in the California summer and let me know how that goes.

        Just throw a baby shot of spray at it to compensate. haha wouldn't take much to overcome 2000 ft extra DA.

        Dont need to, proof is all there, when the correction factors still rate it well over other locations, and the MPH is still low, tells you everything you need to know

        Oh... so your opinion it is then.

        Its not opinion when you look at the #s .

        Pick a 650 HP ( dynojet) car from west coast, pick 650hp ( dynojet ) car east coast, similar cars, tires, weight, trans, gearing etc; look at the different corrections factors, compare the DA's and timeslips. You will see, time and time again, its not DA, its the overselling and underperforming cars
