We had originally planned on running the whole week. My parents and Derrick were going to stay through Saturday, with Grady and I leaving on Thursday afternoon. Derrick pulled me aside on Monday and said, “Gordon and Rudy are going home Wednesday morning. Do you really think that me, mom and dad can do all of this by ourselves?” I looked around. “No.” I said. “This is more work than we thought it was going to be, how about I suggest that we go home early?” he said. I agreed that it was a good idea. We brought it up tentatively to my dad and without hesitation he said, “Yes. There’s no way. We need a whole crew to do this!” That said, we knew that Tuesday was going to be our last day on the salt. And with the noise the motor was making, we didn’t know how much time we had left anyhow.
One of the biggest differences about racing at Bonneville is time. The Rat’s performance life has mostly been spent on the dyno or at the drag strip, where time has a different meaning. On the dyno the bike runs between 2000 and 7000 rpm in 6-7 seconds. In those 6-7 seconds, the bike only runs at the highest rpm for about a half a second. The same is true of drag racing; you are down the track in no more than 10 seconds. On the salt, because of the distance you must travel to get the bike up to top speed, the bike is running over 6000 rpm for more than 60 seconds. This introduces a myriad of new conditions to compensate for. Derrick noticed that the bike was slowing down by the third mile, and we had to figure out why.
Gordon’s biggest concern was the oil. The oil travels from the bottom end of the motor up through the lifters and pushrods and onto the rocker arms and valve guides to lubricate the top of the motor. It then trickles back down with gravity, and the process starts all over again. By three miles the oil wasn’t returning down to the cases. Over a long period of time, the bottom end would be starved of lubrication and cause damage to the engine. We had a couple of options, if the oil is too viscous, it won’t trickle fast enough, so we could try a 0 grade. The problem with thinner oil is that when the bike gets hot, the oil becomes even thinner. We didn’t want to leave it totally unprotected. The other option was changing the oil filter. We were using a performance oil filter that has a stainless element, which lets the oil flow fast. We wanted to slow down the flow so we borrowed a stock oil filter from another team. Stock filters have paper elements, which help restrict the oil flow up, which, in theory would keep the bottom end from becoming empty by the end of the run.
We also discussed how much the heat of the bike was affecting its performance. If we had expansion issues, that was a whole new can of worms to open. We decided to leave that discussion for home, and just keep our fingers crossed that the engine would live for another run.
Because my mom had been watching Grady the whole week at the campground, she hadn’t gotten a chance to see any of the racing. We decided to bring the motor home out on Tuesday so she and Grady could see what this salt racing was all about. Derrick, Gordon and Rudy picked up the bike and pulled it to the short track start line. We brought the motor home right there also, parking it with a view of the track. They got in line with the bike and we knew from the number of people that were in front of us that it was going to be a long wait. Grady ran around in the bus, and my dad watched the races from the front seat. My mom got geared up to stand out there with us—50 sunblock, long pants, floppy sun hat, and sunglasses. She held the umbrella and became increasingly more nervous as Derrick approached the front of the line.
We were in line for over an hour. When Derrick was three before the start so we got him suited up. It takes a second person to help him zip his pants to the jacket, and tighten his racing boots. He got on the bike and rolled it forward as each person took off. He left the zipper to the jacket open until the guy in front of him took off. He grabbed the zipper and pulled it closed with his big racing gloves. When he reached the top, the zipper pull came off in his hand and he just looked at me like “Did that just happen?” I told him not to move, because the zipper was inching it’s way open. I ran to the hummer and grabbed a roll of gorilla tape, which is a super sticky version of duct tape. There was a car waiting to go in the right line, so we had a minute. I taped down the front, and up and around the inside. I put another piece across, making a giant black cross across his chest. I was hoping that the wind wasn’t going to peel the tape off. The car next to us was cranking the engine, trying to start it, but couldn’t get it going. They tried again, and nothing. Buddy, our starter looked at us to see if we were ready. Without the jacket closed he was going to have to cancel the run. Gordon and I stuck it down as best as we could and told him to go. Buddy confirmed that the car in the other line was dead in the water and said over the radio, “We are going to go with bike number 1632, on the short track.”
I told my mom to go in the chase car with the Rudophs, and I ran back to the motor home to watch with dad and Grady. My dad watched Derrick’s run with binoculars. He had a perfect view all the way to the 2-mile marker. He said that he had been noticing that when a car or bike reaches about 130 mph you could see a rooster tail of salt shoot up in its wake. (For any of you who have owned a jet boat, you know exactly what this looks like.) It’s a spray of salt that comes off the rear tire and shoots up about 15 feet. My dad said it was a sure sign that it was a good run. At almost exactly two miles, the tail appeared.
Our radio wasn’t tuning in the results very well, so we couldn’t listen to what his speed was. We waited, and waited. Finally my phone rang--it was Gordon. “What’s the news?” I said. “163.215” My dad and I both screamed. Grady looked up from his pile of matchbox cars wondering what was wrong with us.
The team came back around and we decided to run again right away. They got the bike back in line and Derrick came to the motor home to read the laptop readings from the last run. He said that the throttle was wide open; he couldn’t give the motor any more. The record we were trying to beat was 171.667. Yes, only 8 mph away, but that can be a continent sized gap to traverse. He and my dad discussed the gearing of the bike and decided that they should think about changing it, if they do this again, but that was a major change.
The other condition we hadn’t fully compensated for was the density altitude. Because Derrick was using what is called a “closed loop” system for his fuel injection module, it should compensate for air density and altitude on it’s own, but it’s not perfect. Like Derrick’s bike, cars are closed loop systems, and they have an oxygen sensor that determines the gas to air ratio that is appropriate for the engine. That is why you can drive from below sea level to the mountains and still have a car that runs well. On carbureted bikes, or old carbureted cars you have to manually adjust the jets, or the engine will run too lean (not enough gas) or too rich, or fat (too much gas). When you run down the road it will ultimately only effect your gas mileage, but when you are racing, this curve has to be perfect to get the most out of your engine.
Derrick had written a program for the EFI (fuel injection) before he left, guessing at what he would be running based on the salt flat’s elevation of 4320feet. However, temperature and humidity affect the actual altitude, increasing or decreasing it on a mathematical scale. This phenomenon is called Density Altitude (DA). DA has the most effect on airplanes, but again, we are dealing with thousandths of mphs, it matters on the ground too. The temperature and humidity also changes based on the time of day that you run. When Derrick ran his 163.215, the DA brought the altitude from 4320 to over 6000 feet. This would mean that we had less air than we thought and the motor was running too rich. Derrick had confidence in the oxygen sensors, and decided to run the bike one more time, as is. If we decide to do this again, you can bet that we will have a better handle on this DA thing.
As he and my dad are discussing this, he is still in full gear, with sweat just pouring off of him. “You have to get out of your suit Derrick,” I said. “I can’t, if this zipper comes down, I am done.” He had peeled back the tape and he stood up. When he did, the zipper slipped down another 6 inches. “Take it off, we have to try and fix it.” Rudy came in and asked if we had any other jackets with heavy-duty zippers. Derrick said that my dad had one in the closet that he thought would work. Derrick went back to the bike and Rudy yanked a zipper pull off of a pocket of an old jacket. It looked good, but it wouldn’t fit on the suit. He tried prying it with pliers, but we couldn’t make it work. He said that you would be surprised how many zippers there are out there, and we needed just the right one to make it work. We grabbed backpacks, purses, sweatshirts, anything we could, and none of them were the right zipper.
We brought the jacket out to Derrick and told him the bad news. He pulled the bike out of line and we thought of other ways to get the jacket back together. This was a brand new $400 leather suit that was now covered in glue, leather laptop bag patches, tape and goo. “Wait,” Derrick said, “I have another racing jacket in the closet. It isn’t leather but it has a big zipper.” Rudy and Derrick ran to the motor home and grabbed it. Rudy stripped the pull and tried it on the leather suit—a perfect fit. Team HPE lived to see another run. We got back in line and waited for our turn.
My dad, Gordon and I went down the return road to get him. He was parked quietly, waiting for us when we got there. “It felt good, until the third mile, but not as fast. Oh, and something hit me in the leg at about mile 2, does anything look weird on the bike?” Gordon looked down and saw oil all over the side of the bike. “Your oil plug is gone, we’re done.” “I guess that’s it,” Derrick said, “The motor is done.”
We towed the bike back to the timing station. “Short track, bike 1632” My dad said. 158.257 mph. At 1620, on 8/17/10 our run for the record ended.
We went back to the start line to switch drivers. My dad got the motor home ready to roll and Rudy said to me, “I’ll ride in the back of the hummer to direct Derrick, Why don’t you pull your brother, and Gordon will drive our car back?” “Heck no!” I said. “I’ll drive your car, let Gordon pull Derrick back.” The day before there had been a little bit of an incident. My dad had been pulling my brother back, and he had taken a circuitous route back to the pits. As mentioned before, pulling the bike on a strap is hazardous, and if Derrick isn’t ready to stop when my dad does, he will crash into the back of the hummer. Also, if there is slack in the line and my dad drives forward too fast, the bike gets yanked. Well, my dad had to stop for some cross traffic and Derrick almost lost control of the bike. Derrick was in full leather gear and had been on the back of the bike for nearly 30 minutes in 95-degree heat. He became furious and he and my dad had some words. Derrick later apologized, but it was definitely not a highlight of the week. I am smart, for a blonde, and after that happened, you can bet that I wasn’t going to have anything to do with being the driver of the pull vehicle.
Gordon took Derrick back to the pits and I waited for my parents to move the motor home. I drove back to the trailer to find that Gordon and Derrick had just arrived. Derrick was taking off his helmet and he had a strange expression on his face. “What happened?” I said. Derrick pointed down to the gas tank. A golf ball sized dent scarred the yellow paint. I looked at Gordon and Rudy. “We had a crash.” “What!?!?!?!” I said. “I did the exact same thing your dad did.” Gordon said. “I told him I was going to stop, and I did, briefly, but then I forgot to tell him we were going again.” Derrick had his feet on the ground and was waiting for the word that that they were moving again. The line was slack, and then all of the sudden Gordon pulled forward. Derrick, needless to say, wasn’t ready, and the bike was yanked forward. It tossed him to the side and landed on his leg. He was dragged about 3 feet before Gordon was able to stop. He jumped out of the car and he and his dad lifted the 600-pound bike off of Derrick. Derrick may have gone cheap on the race suit, but not on the race boots. His $600 boots saved his foot. The handlebars bent and that is what dented the tank. Gordon felt horrible. To try and bring a little levity to the situation I said, “So what you are telling me is that we go 163 mph without a problem, and you guys crash going 1 mph? Who’s going to tell dad?” Derrick quickly pointed at Gordon. “I’m going to wait till he has a few marguerites, then I’ll tell him.” Gordon said.
Gordon and Rudy left the next morning, after a nice dinner that involved just enough drinking to break the news. (My dad took it well.) Our racing was done and Wednesday became our pack up day. It was hotter than ever and we all fried in the sun and dryness as we repacked and organized the trailer. We left Grady inside the motor home, because the conditions were just too harsh. Around 7pm, as the sun was going down, the intensity finally let up. Grady came out and spent a half hour at his favorite activity--touching the wheels of the motor home. This kid LOVES busses, trucks, and especially wheels. (Hmmm, I wonder where that comes from) We had rinsed off the bike, which was covered in salt, and it left a big puddle for him to splash in. He shrieked with joy as he jumped in it. Then he sat down. He was soaked, and covered in salt. I said to my mom, “Why don’t we let him run around a bit without the salty wet clothes?” She shrugged, and we stripped him down to just his shoes. He squealed with excitement and started sprinting across the salt in his birthday suit--free at last! Life is about building memories, and we all had some this week, but I think that Grady will have the best bragging rights. He streaked in the salt when he was 14 months old. Who among us can say the same?
Well that’s it. I am writing this from home, with my parents hours away from Chicago. We didn’t beat the record, but I think that we can all feel good about our efforts. Derrick drove it flawlessly and coming within 8 mph with a street bike, is no small feat. To give a little perspective, another bike, with a supercharger, in a totally different class made nearly twice the horsepower that we did (over 250) and had a record setting speed of 159mph. For our Lab Rat, in it’s rookie year, we really couldn’t have asked for much more.
We want to take a moment to thank all of the people who supported us in this crazy ride--we would have never made it to Bonneville without you. Our sponsors were Hemi Performance Engineering, Kaman Tool, Rob Bult at Illini State Trucking and Marigold, Dark Horse Crank Works, G.A.S., and Mysza Performance. Our team was made up of Bill Stefinisky (the builder of the Rat, and the guy who keeps everything running back on the home front), Gary Mack, Derrick Roderweiss, Ron Roderweiss, Irene Roderweiss, Grady Kaman Roderweiss-O’Brien, Louis Dalgaard, Jessie, Andy, George Jaresko (who drove out 600 miles from San Fran, and was only able to stay 24 hours), Rudy and Gordon Rudolph, Brian Truesdale and of course, me. Also, thanks to all of the friends and extended family that offered advice and support, you know who you are.
Will we be back next year? That remains to be seen. If we do return, we will certainly have a better idea of what we are doing. They say that once you get salt fever, it’s hard to stay away. I don’t know if that is true, but I do know that there is nothing in the world like Bonneville. Even if you aren’t a race enthusiast, even if you have never paid attention to anything that goes fast in your life, I recommend you go there for Speedweek, at least once. The camaraderie, the passion, the excitement, and the “other-worldness” of the salt desert cannot be found anywhere else.
Until next year…
Wendy Roderweiss
