Well folks, summer is definitely here. It's mid-August and the season is in full swing. It's that time of year when racers are thinking of how their points are lining up for that run toward the championship in October. For much of the country it's also the hottest time of year. Temperatures have crept well into the 90s and humidity is at an all-time high. With all that we have to tackle in preparation for any given Saturday night, one thing that is very easy to forget is ourselves. You can compare your body to the radiator in your race car. If it doesn't do its job of keeping the engine cool then that motor is going to blow. If you don't keep your body cool, the results could be devastating especially if it decides to shut down in the middle of a race.

With that concept in mind, resident Tech Editor Pete Epple crafted a pretty interesting story on heat exhaustion and how to avoid it. And thanks to our little adventure two months ago at an event for a sister magazine (the Hot Rod Power Tour), we found a new way to use a tried and true product for staying cool during those hot summer nights.

Speaking of adventures, as I write this, Bob Bolles has officially begun the 2013 AMSOIL Great American Circle Track Tour. He texted me the picture you see here this morning. He made it to Utah on his way to the West Coast swing for the Tour. Keep an eye out on Facebook and circletrack.com and, of course, the printed magazine, for all of his adventures and stories as he visits some of the finest tracks in the west.

As you've come to be accustomed to when you open the pages of Circle Track, we have a ton of great tech for you this month. Jeff Huneycutt puts Eagle's Armor ESP treatment to the test in a back-to-back dyno flog of our 350 SBC mule. He also has some valuable two-barrel carb tuning tech for all you racers out their running a class that requires them…and there are a lot of you. We're also covering ignitions, an install of Auto Meter's new Elite Series gauges, and much more.

Unfortunately, as this issue was going to press, we learned of the tragic passing of Jason Leffler in a Sprint Car accident at Bridgeport Speedway in New Jersey. I had the pleasure of speaking with Jason on several occasions. He was always very accessible, easy to interview, and was one of those genuine guys who just loved racing. Like we did last month for Dick Trickle, turn to page 82 and you can see some Circle Track archive photos of Jason.

Until next month and in honor of Jason, go fast and turn Lef.
