How many of you use a weather station to help tune your race car?

The pros are doing it and it would help you I am sure!

Check out some units here to add to your arsenal!

I like this hand held portable unit that would be great for carrying to the lanes to keep updated for last minute adjustments

Kestrel is throwing some support the way of UAC so if you are interested in something like this consider them please.

I will personally have the 4250 racing model at the BOR this weekend, so if you see me ask to check it out

It has a huge advantage of being the size of a cell phone so it can give you information all the way into the staging lanes for last minute adjustments!

Knowing how the weather influences the way a car drives is the first step to optimizing performance. The Kestrel 4250 Racing Weather Tracker is the next generation of weather monitoring. Even slight fluctuations in weather conditions like temperature, humidity, barometric pressure and density altitude can affect your car's performance. Kestrel Weather Meters provide quick, accurate information to help you decide what changes need to be made, before even making a lap around the track or a pass down the drag strip.

In pits around the country, racers have been trading in their bulky and expensive weather monitoring stations in favor of the portable Kestrel 4000. Now, Kestrel is proud to introduce a unit designed specially for them — the Kestrel 4250 Racing Weather Tracker. A 2000 point data log lets you keep track of the conditions for each race day, and the optional computer interface lets you upload all the data to your PC or laptop — making long-term storage, in-depth analysis, and detailed charting of stored data a breeze.

It measures every environmental condition with unrivaled ease and accuracy — and all in a cell-phone sized package. Temperature, humidity, barometric pressure, and density altitude are all continuously measured, and data is stored either manually or automatically. Portable and easy-to-use, Kestrels give racers and pit crews relevant data to gain that competitive edge at a fraction of the cost of other systems currently on the market.

The Kestrel 4250 features the best portable sensors available, assuring that it's dead-on accurate. Each unit is individually calibrated before it leaves our manufacturing plant, and comes with a certificate of conformity. We even hold four patents on the technology our engineers have developed especially for the Kestrel 4250.

ET predictors is what you have. I have used a ET predictor for years while bracket racing. I carry a electronic weather station along with a lap top for calculation. I use this program:

http://www.quarterjr.com/density.htm

Works very well and is very actuate. As most racers know, weather plays a big part in the horsepower a motor makes. This can affect ET a lot. And, most racers know that ET's are quicker, overall, in cool weather as opposed to hot weather. Simply more oxygen is present. But, how about when the weather changes a lot on race day. Example, say you run a 7.25 at 3 pm and it is a 100 degrees. First round is at 8:30 and the temp (and other weather factors) is 80 degrees? The car should pick up but how much? The ET predictor calculates the weather changes from the weather on the first run and provides a predicted ET as a result. These tools will help the bracket racer stay real close to their dail as the day goes on. Same thing goes on day events where the temp is low at 9 am and gets hot by first round at 1 pm. How much will the car slow down with rising temps?

Works great for me when NA. However, the motor reacts to temp a little different with nitrous. Still collecting data on that.

I am cheap so I just use my phone and http://www.weatherunderground.com
Here is an example of the station close to the track I hit the most. Even has tabular data if you just log you times through out the day and you can look up all the data later. Makes a nice log for the next time you are at the track. Here is the data:

pfer10,
But I love a new gadget LOL ;D


I really like this unit, has huge benefits at being at the actual location at the actual time your running.

As you know most internet websites and connections are plagued by delays and hiccups.

This units results are instant and accurate.

Even a big advantage over the huge expensive units the big racers have mounted in their trailers because those are mobile to the staging lanes!

I know it is another expense but depends on how you look at priorities I think.

Either you like the options this offers or you don't. If you do, check it out
