Rob Bodle and I teamed up again for an endurance race in the 05 Steeda Mustang. The guys at Ponder Racing had completed the repairs after my big accident at Road Atlanta's Turn 12 during the very wet NASA 3 hour enduro.
Luckily the impact with the tire wall didn't damage the suspension and the repairs were limited to some light body and paint work, replacing the windshield and power steering cooler -- and removing several pounds of rocks from the gravel trap. The windshield was cracked from a rock striking it on the inside!
Rob ran the car during the Friday test day and reported a lack of grip from the Toyo Proxe tires. The tires were not the new Proxes R888 competition DOT radials. Instead they were last year's RA1 model. Toyos are required for NASA events; however, in SCCA we can run any DOT-legal tire. At last year's ARRC race, I was able to run consistent laps in the low 1:39s on BFG tires. Rob chose to run the RA1s this weekend because he already had them.
 This weekend the ECR and ProIT races were fillers for Formula D pro drifting. I qualified the car Saturday morning. The track was very dirty because of heavy rains overnight. Several areas of the track were covered in fine sand and Georgia red clay. In particular, turns 3, 4 (the esses) and 10b were very dirty. Several cars spun during qualifying. I couldn't use the full torque of the V8 because I would simply spin the rear tires. Our goal was to get down into the low 1:40s to insure that we qualified in front of the ITR, ITS and Spec Miata competitors. I really struggled on the Toyos and with the dirty track -- finally posting a lap time of 1:42.359 to qualify 3rd in class, 4th overall, behind the ITO #53 Viper GTS driven by Tom Wilson (1:36.791) and ITO #7 driven by Brion Gluck (1:37.305). I pitted and we switched drivers. Rob went out for the rest of the qualifying session.
We knew we couldn't beat the Viper. It was up to 8 seconds a lap faster than our Mustang. The SCCA ITO class is a catch-all class. You never know what you will be running against. The Viper was originally a Motorola Cup endurance racer. It was a trick piece and sounds awesome. The #7 Mustang was extremely fast on the straights. However, they have had reliability problems in the past. Our strategy was to push them hard from the start and hope they broke something. Rumors in the paddock reported that the Viper could not go full speed for the full 90 minutes and would have to lap times closer to what we could do. So going into the race 2nd place looked promising and 1st looked like a remote possibility. I would started the race and Rob would finish it.
We filled the Mustang's fuel cell up and reported to the grid. After 2 pace laps, I got a good start and moved into 3rd position passing the #79 ITR driven by Taylor and Ben Robertson. Torque is a good thing! The goal was to push the #7 Mustang into a mistake or break. However, the Toyo tires were very difficult to drive. I was able to keep in touch with the Mustang; however, the #79 ITR was able to stay with me through the esses and some other corners. Our lap times were very similar. I'd pull out a big lead down the back stretch and he'd catch me in the esses. We yo-yo'ed like this for a couple of laps. I was frustrated because I wanted to push harder to run down the yellow 'stang but the Toyos wouldn't perform. Finally I found that I could make the car come down to the apex and not push out like a pig if I broke the rear end loose on entry. A light lift of the throttle, massive turn-in and then feed power back in. Big understeer followed by light oversteer. Hey, I was drifting!
Well, this worked great for a couple of laps. Then my tires started to get over heated. Entering turn 10A my drifting talented failed me and I did a perfect 180 degree spin. Was lucky have kept all 4 wheels on the pavement. Grabbed 1st gear, did a nice 180 degree burn out and resumed in 4th place.
The middle of the race was a big experiment. How could I make these Toyo tires work? The drifting technique was the fastest method but the tires could only handle this for 5-6 laps. So I had to cool them down periodically. I started running 4th gear through turn 1. This is pretty difficult as you are carrying more speed to the apex but aren't driving as hard as when you run 3rd gear. Several times the car washed out mid-corner and I had to catch it before it left the track.
The new brakes were great. I was able to pass 1 or 2 Spec Miatas under braking for turn 10a at the end of the long straight. A big heavy car like the Mustang shouldn't be able to out brake a light-weight Miata! Those brakes ruled! One fella driving an ITC Honda asked after the race is we could leave a little more room between the cars when we passed him. The closing speed had to be at least 50MPH. Evidentially we were moving his little car around with our air wake.
The #7 Mustang made a couple of pit stops to fix problems. Back into 3rd! Finally I caught the #79 ITR and passed him on lap 20. 2nd! The rumors about the Viper's fuel mileage were totally false. He was running 1:36s and blew by me on lap 29.
At the ARRC 3 hour race, we were able to run about 1:30 minutes on a tank of fuel. So we had planned to dump 5 gallons in the car during our pitstop. SCCA requires the car to be stationary for 5 minutes and the driver must be out of the car during refueling. This rule is to maximize safety (we aren't Formula 1) and to reduce costs. Teams don't have to buy very expensive refueling rigs and can use ordinary dump cans and funnels.
Well, we didn't get the 1 hour mark. On lap 34 while heading into turn 1, the car stumbled. Glancing over at the fuel pressure gauge I could see that we were out of gas. The Mustang has a fuel cell with a central reservoir. Fuel is pulled from the corners of the tank into this reservoir and then pumped to the engine. This arrangement allows every drop of fuel to be pulled from the cell. Why were we out of gas at 60 minutes when we ran 90 before?? I could probably make it back to the pits if I conserved fuel for 2.5 miles. In the middle of every corner the car would stumbled. On the back straight it laid down. Coasted into 10A, refired and got in to the pits! I jumped out, PRS crew refueled the car and Rob got back in. Five minutes up and Rob rejoined the race. We only had 5 gallons in the pits so it was obviously that we wouldn't make it to the finish without another fuel stop. Arg!
Rob did a great job during his stint keeping the car in 2nd overall. However, on lap 49 the car was again starving for fuel and Rob had to make a dash to the pits. Driver out, fuel in, driver in, resume race. The track announcer wondered why on earth we were changing drivers so late in the race! We weren't! We needed fuel.
At the 90 minute mark, Rob took the checker flag in 3rd overall, 2nd in ITO behind the awesome Viper. Our fast lap was 1:41.208. The Viper's was 1:36.113. Turns out the Viper had a 30+ gallon fuel cell installed. 2nd overall went to #8 ITS BMW driven by Matt Reppert.
A good weekend overall. I'm frustrated by the Toyo tire performance, or lack thereof. However, we achieved our goal of finishing 2nd in class behind the Viper.
Till the next race, Dwight Kelly
