One of the challenges for Dave Martis with the G35 is finding ways to put the cars awesome power on the track, but Martis says he very pleased with the progress so far.
A few klicks south of Phoenix, Arizona, is where you'll find Firebird International Raceway, the site of the highly anticipated second round of the Pro Track Challenge Series. The short 1.6 mile road course has been described as a somewhat funky track configuration, as it's a dragstrip connected by turns on either end, picture a spoon with finger grips.
With a second round class win at Firebird Raceway, the K&N Motorsports Infiniti G35 now has a good lead in the Redline Pro Track Challenge Series points championship.
"The course is tight through the twisty sections so you need a setup to be able to throw the car around, and this section doesn't require ultimate power," explained Dave Martis, the Research and Development manager overseeing the K&N Motorsports Infiniti G35 development. "But then you come screaming onto the dragstrip, which has been used for years and the traction properties are totally different, so the car wants to do crazy stuff. Once you get it fairly straight, you mat the throttle and rocket down to the end of the dragstrip, then brake hard to get it whoa'd down for the first turn."
The stage was set for ideal day of practice on Friday, although Mother Nature had other plans. Racers and teams awoke to steady rain that made for a very soggy morning and a very slippery track. "It rained all day Friday and up to about 1pm on Saturday," said Martis. "The track dried enough by about 2:30 Saturday to allow us to lay down some laps with the G. The car was quick, but the setup wasn't ideal for the track configuration. We made adjustments Saturday to allow Paul (Brown) to get around the track quicker and the RTLA officials again asked me to run the car against the Circuit Battle big guns for the TV show."
In stark contrast Sunday was a beautiful day. The air was cool and the G was laying down some serious power. Suspension changes were made the car was clicking off lap times in the high 1:03 range on worn Hoosier tires (track record was 1:04). Overall the G35 with Brown at the controls came away with a first place in the Time Attack, with a lap of 1:02.835, securing another first place finish in class. The K&N Motorsports Infiniti G35 now has a solid lead for a championship title.
We made some changes to the suspension to make the overall platform of the car more stable through the turns," continued Martis. "These changes allowed the car to transition faster with more control. We also switched to a different type of differential in an effort to get the car to drive off the corner with less wheel spin. The new differential really helped in this area. The car has so much power it easily breaks the tires loose when you mat the throttle. Now it hooks up much better."
"For the Circuit Battle TV show we bolted on a fresh set of Hoosiers and started at the back of the pack because we gave up the qualifying race to run the Time Attack event. The sticker tires gave us much needed grip and Paul drove it hard to come from the back to fourth in the Super Session race."
The car turned scorching lap times and laid down a 1:02.393 in the race, second only to Lou Gigliotti in his ALMS Corvette, who bested the G by less than a heartbeat at 0.053 seconds, with a lap of 1:02.340. "For the two lap shoot out, we made it to the semi final round, and got beat by Lou's Corvette, but Paul was just mere inches off his bumper at the finish," adds Martis.
In examining the areas in which the G35 can still improve Martis says, "Rear grip is an area where we still need to make improvements. A key component in any road race car is for the driver to be able to get on the gas early before the completion of a turn to increase the car's speed down the straight sections of the track. This equates to the fastest lap times. We are still working on ways to get the power the car makes to the ground. We are making progress, and make changes after each event, and we will get there. It is all part of the development process when you build a race car."
As the weather becomes hotter, managing the heat will also become a factor. "We haven't had a problem so far this year and didn't last year either. But we are running the car much harder this season, and also pulling double duty so to speak (we race in both Pro-Time Attack and Circuit Battles each weekend). As the summer temperatures go up everything will get heat soaked and that might take its toll on parts. We've done a good job in ventilating the car, and have coolers where needed, but we need to be prepared, and so we have spare parts on hand in case of heat related failures."
Round three of the Redline Pro Track Challenge Series will be at AAA Speedway in Fontana, California, on the weekend of May 28 and 29.

Ferguson says K&N and his other sponsors have helped to get the car "super-nice."
"The Carolina Clash would like to announce the official results from the Skyler Trull Memorial race," read the message from the Carolina Speedway in Gastonia, North Carolina. "After post race inspections Chris Ferguson has been declared the race winner in the Dirt Late Model Series."
Chris Ferguson says he's got his new car dialed in just the way he likes it and he feels optimistic about the 2011 season.
"The reason why they decided to have a post race inspection," explained the Mount Holly, North Carolina racer, "Was because of tire chemical alterations being a problem in Dirt Late Model racing. They stated before the season started that they were going to check tires, and the race winner's tires were altered, so we were declared the winner."
Tire samples were taken from qualifying and the feature event and sent to an independent laboratory for testing. The tire samples from three drivers did not conform to the American Racer Benchmark. All three drivers are currently appealing the results. Ferguson, on-the-other-hand qualified fifth out of 32 cars on legal tires, and by lap 38 in the feature, he had moved into second place before running out of time.
Ferguson claims he will always have his Dirt Late Model car equipped only with K&N Filters.
Ferguson says he's very optimistic about the 2011 season. "We have a lot of big races scheduled, and so far we are doing really good running against top notch competition. I'm a young driver, so I'm still learning a lot of the tracks and I feel like the more I learn, the better I get."
Ferguson began his racing career at the age of 12 in go-karts, and in only three years of competition, Chris racked up over 100 feature wins. Included in those wins were races that successfully led him to becoming a WKA Two-Time National Champion in the junior ranks.
Winning the 11th Annual Skyler Trull Memorial on legal tires was a great boost for the entire team.
Now for the past three years Ferguson has proudly been representing team owner Jack Starrette, in the K&N sponsored number 22 Late Model. During that period he has already amassed 17 feature wins and set several track records at both Carolina Speedway and Toccoa Speedway.
Ferguson says the team made a few changes to the chassis during the off season which has paid off so far. "We also have gained a lot of factory support," he says, "So the learning curve has sped up a good deal for us. My goals are just to win races this year. We would like to just be consistently fast enough to win all year."
"I'm excited about this new car and all my product sponsors like K&N that have helped me get this car the way it is right now. It's a fine piece and there is nothing on it that's not super nice."
Chris Ferguson Motorsports will be back competing in the Carolina Clash Series at Lancaster Motor Speedway in Lancaster, South Carolina, this weekend.
"Again, we really want to thank K&N for all the backing. We support top notch products and will always have our Dirt Late Models equipped with K&N Filters."
Jason Johnson understands that using K&N products continues to give him the added advantage in the hostile Sprint Car racing environment.
"It felt great to start the 2011 racing season off with a victory," commented K&N sponsored Jason Johnson. "The JJR organization has been working hard during the off season, and to come back to America and win the first night in competition just shows how dedicated and strong this team really is. The very next night, finishing on the podium completed a great weekend."
The JJR team's goal for 2011 is to reach 25 plus wins.
There were 52 Lucas Oil ASCS Sprints at the 38th Annual Spring Nationals, and after spending a part of his off season in Australia racing, this was Johnson's first race back on U.S. soil in 2011. And, the JJR number 41 team managed to get their first Lucas Oil ASCS presented by K&N Filters win of the young season. Johnson followed up his win in the first of two nights of racing at the historic 1/2-mile clay Devils Bowl Speedway in Mesquite, Texas, with a third place finish the next evening.
For the Jason Johnson Racing team, 2011 will be a highly diverse season. Competing for the Lucas Oil, presented by K&N, American Sprint Car Series is among the top priorities of competition throughout the season. However, when he's free due to scheduling, JJR will compete throughout the United States, within some of the ASCS Regional Events. The team also has plans to compete at the 51st Annual Knoxville Nationals, along with periodic events with the World of Outlaws.
The 38th Annual Spring Nationals was Johnson's first race weekend back on U.S. soil in 2011, and he drove away with a win and third place finish.
"For the past eight years, I personally had very little down time during the American off season," Johnson said. "With great opportunities to compete in Australia, my wife (Bobbi) and I make an annual trek down-under to compete with the World Sprint Car Series (WSS). As soon as the season ends here in November, we head off till the beginning of a March return. This allows me to stay sharp at the wheel, competing 12 months a year. In addition, it's a wonderful opportunity to visit another great country."
"We definitely have 2011 goals we would like to accomplish," continued Johnson. "For the past several years, JJR has won 20 to 25 victories per season. For 2011 we would like to produce a few more, with perhaps 25 plus victories this season."
"Obviously, with JJR currently leading the ASCS car owner championship, we would like to capitalize on another championship. Although this season, we will have to reap the benefits as owners, due to the absence of not competing at the first four national events personally."
Jason Johnson Racing's other big goals for this year are to win some of the spotlight events such as, The Fred Brownfield Memorial, the 360 and 410 Knoxville Nationals, the Short Track Nationals, and the Eagle Nationals. "And any other big events JJR competes in," adds Johnson.
"With this being Jason Johnson Racing's second year in existence, we greatly appreciate the opportunity to work along with branding the K&N name throughout the 360 marketing area. JJR has been a lifetime believer in K&N products, and it is great to be affiliated with such a successful company, and to get such an obvious track advantage. Utilizing K&N product within our JJR organization, we know we have a clear advantage in the dirty climate of sprint car racing."
Up next for the JJR team will be the race in Little Rock, Arkansas, at the I-30 Speedway.
