A Great Beginning for 2016


April in the Upper Midwest is a mixed bag when it comes to weather. It can be as snowy as any day in winter, or it could be warm enough to be doing yard work in t-shirt and shorts. At Fart-hinder Central in northern Minnesota, the race cars are often still under a pile of snow or hidden away in a garage that can't be reached by anything short of a sled dog team. Since the first ChumpCar race at Road America is usually in April, Fart-hinder Racing has usually chosen to skip this event.

This year, however, was different. Following a mild winter, temperatures in March were often warm enough to work outdoors. In addition, Snowbird Mike Mandy was anxious to get a start on racing and returned to his summer home near Ely several weeks earlier than usual. The team's primary race car, a 1999 Saab 9-3, was in pretty good shape at the end of the 2015 season, in need of a clutch after an early failure at the autumn race at Road America. The car had been left over the winter with team member Aidan Hicks to do the necessary repairs at his place of employment, a car dealership in the Minneapolis area.

The decision was made to enter the ChumpCar Landjaeger Cup at Road America, a pair of 7 hour races at America's first and still the best road racing facility.

Some changes in the ChumpCar rules meant we could use something other than OE springs, though there were still restrictions. Some measurements to the assorted coil springs in the parts cache found that the front springs from a classic 900 were the same outside diameter as those on the NG900/OG9-3. However, the wire size was a little larger, meaning a stiffer spring rate. That spring rate would be increased further by trimming a few coils. There is not much available for the rear springs due to their conical design, but Hanover European Parts had given us a pair of Eibach lowering springs for the rear. They weren't quite racing springs, but lowering the rear end would also lower the center of gravity.

The front brakes were upgraded to the larger rotors found on the 9-3 Viggen, 308mm vs. 288mm that came on lesser 9-3s. The calipers and brake pads are the same, just moved out a little with a slightly different mounting bracket. The rotors were cryogenically treated for longer wear, sourced from series sponsor Frozen Rotors.

Minnesota Saab Club member Jim Hickstein happened to have a complete Viggen clutch package that he donated to the race effort. While the stock clutch has generally not been a problem, the beefier Viggen clutch would give an additional margin of reliability.

Race weekend looked promising weatherwise, with clear skies and temperatures around 70 degrees. We zipped through registration and tech with little difficulty, met the new Central Region Chump Staff, did a few final checks on the racer, then went to dinner in Sheboygan, where we usually stay.

Team captain, Tim Winker, decided to see if there were any German restaurants in the area, since that region was where many German immigrants settled in the 1850s. A place called Al & Al's Steinhaus looked promising, so Tim, Mike and Mark found their way there. All three have spent time in Germany, and were hoping the menu offered more than bratwurst and kraut. It exceeded all expectations, with a full German menu and a salad bar full of pickled this and creamed that. Al & Al's will likely see the Fart-hinder gang at future Road America race weekends.

In addition to the four drivers who would also act as crew, John Hicks brought his 17-year-old daughter, Shania, for her first race weekend. She was pressed into service to maintain notes on what happened during pit stops and to check tire pressures. She also took some photos of the Saab in action.

It was a cool spring morning when John Hicks took to the track in the 9-3. His stint behind the wheel had only one incident, a tap on the left rear door by a Toyota MR2. The Toyota driver was given a Black Flag and had to spend several minutes explaining to race officials why he hit another car. In the meantime, John continued to reel off laps until time for the driver change.

Mike Mandy was the next driver and again there was nothing serious to his shift behind the wheel. Mark Fitzpatrick took over at his designated time and started to reel off some quick laps. However, the low fuel warning light came on earlier than expected, and Mark cut his time at the wheel short, returning for the final driver change of the day with two hours left.

Tim Winker also had no issues aboard the Saab, but with 20 minutes remaining in the race, the low fuel light came on again. The earphones had become dislodged enough that Tim could no longer hear what the crew had to say, but radioed to them that he would be coming to the pits in a few laps. As he drove past the pits, the other drivers signaled that he should stay out. Tim cut back his speed a little to preserve fuel. He made it to the checkered flag with no difficulties; nary a bobble from the engine. When he pulled into the paddock, team members informed him that if he had come in for fuel, they would have dropped at least one position in class and several places overall. As it was, they did not lose any positions in the final standings, ending up 12th overall and 6th in a class full of fast BMWs.

The 9-3 performed well, and all drivers ran faster lap times than in previous years. Mark Fitzpatrick ripped off one lap at 3:02.50, the quickest we have ever turned in this car. The transmission gearing was perfect so that the drivers only had to use 3rd and 4th gears, topping out at 120 mph, higher than most of the cars competing. The new rear springs helped the Saab to set up for corners with a touch of trailing throttle oversteer. The larger brake rotors allowed for shorter stopping distances, hence quicker times at all corners of the track.

The Dunlop Direzza ZII Star Spec tires showed a bit of wear on the outer edges from hard cornering, so were swapped around, with a couple of better used race tires installed on the front. The brake pads, however, showed a bit more wear than we have seen in the past. The combination of medium friction EBC Yellowstuffs racing pads and the new Frozen Rotors may have been great in stopping the car, but also caused them to wear faster. The pads on the rear were worn down to the metal backing. We had some decent used pads for both axles and installed those, hoping to get through Sunday's 7 hour race.

Tim was first in the driver's seat for what he referred to as "a leisurely Sunday drive." In the process he set a personal best lap time in the 9-3. But it was not without some drama. The brake lights insisted on staying on as the Saab left the pits for warm up laps. Rather than risk a black flag, the team called Tim in during the pace laps and rearranged the brake light switch ever so slightly. Problem solved and Tim hit the track again before the green flag, though he was way behind the pack.

John was the next driver, for what was likely his final chance to race with us for a few years. He has taken a job in Italy and will be moving there soon.

Mike took to the wheel for his stint, followed by Mark. All still looked well for the team with quick pit stops and no need to change anything. As the race headed into the final hour, Mark chose to use the brakes less in an effort to save what little brake pad material remained. Even so, he set the fastest lap for the Saab in Sunday's race at 3:03.57.

The checkered flag dropped on schedule and the Fart-hinder team began the celebration, along with all other finishers. Our overall position of 13th was satisfactory considering that our Saab has the original engine as installed at the factory in Trollhattan. We were again 6th in class, behind a bunch of modified BMWs. Our pit stops were better than in past years, very close to the five minute minimum required by ChumpCar rules. There was no extra time spent in the pits for repairs, and the brake pads lasted to the finish, though the pad material on the rear was paper thin.

 A successful race weekend, by our account. After our dining experiences at Al & Al's Steinhaus and the Saturday meal at Schwartz's Supper Club, we're thinking about changing the team name to "Fart-hinder Racing and Dining Society."

THE END.

Preparing for Season 7

The Fart-hinder Saab 900
 on the pace lap of its first race.
It was six years ago that Tim Winker got a message from Darrell Peterson asking about a Saab 900 that was hiding in Tim's garage. Tim had posted a note about maybe turning it into a racer for the inaugural ChumpCar World Series race at Brainerd International Raceway in June. That was in early April, 2010. Eight weeks later and the Saab was on track. Other team drivers and car builders were Greg Wold and John Hogdahl, and all were looking forward to their return to racing during a pair of seven hour races in a $500 crapcan Saab. Alas, it was not to be, as something apparently went wrong in assembling the engine to the gearbox (the gearbox sits below the engine and also acts as the oil pan). The rod knock death rattle put the Saab behind the wall after only a couple of laps. Rather than swap for another engine, the team chose to pack it in and race again another day.

Thus begins the tale of Fart-hinder Racing. Though most of the drivers have changed, Team Fart-hinder is now preparing for a seventh season of endurance racing, still with Saabs. That original 900, a non-turbo 2.1L hatchback, remains with the team and is likely to see some action during 2016. It is estimated to have over 10,000 racing miles on the chassis during its six years since becoming a race car.

The primary team car now is a 1999 Saab 9-3, powered by a 2.0L turbo, acquired from Team Cougar Bait in 2014. The 185 HP engine is believed to be original to the car, has never been modified, and has an estimated 160,000 miles on it. The oil pan was removed last year to see if there was evidence of sludge, a known killer of Saab engines in street use, but the inside of the engine looked new, thanks apparently to frequent oil changes by previous owners.

The first race on the Fart-hinder calendar for this season is a ChumpCar dual-7 at Road America in mid-April.

The 9-3 did not need a lot of attention over the winter as it had succumbed to an early clutch failure during its last race in 2015. A few upgrades should make for improved lap times in that racer. The failed clutch, a refaced OE disc done at a local shop, has been replaced by a new Saab Viggen clutch, donated by Minnesota Saab Club member Jim Hickstein. In addition, the brakes should improve with the larger Viggen rotors (308mm vs. 288mm for standard 9-3s) and steel braided brake lines. Frozen Rotors have proven to be outstanding on both the 9-3 and 900, so they were again the source for the Viggen rotors. Mike Mandy, Mark Fitzpatrick, the father and son duo of John and Aidan Hicks, and team captain Tim Winker will do the driving and act as crew.

The 900 will need a bit more attention, as the gearbox took a lot of stress last season thanks to the welded ring-and-pinion. It still works in all gears, but there was a good sized wad of metal shavings on the magnetic drain plug when the fluid was last changed. The front motor mount also needs repair or replacement as the mount to the body punched through the two bolts that anchor the gearbox to the chassis. That made shifting difficult, particularly into 5th gear. That car also suffered a broken exhaust and failed clutch at last year's final race. To do the transmission repair properly will require that the drivetrain be removed from the car. The team has gotten pretty good at removing and replacing the engine/gearbox assembly, now able to do a complete swap in about five hours. The planned debut for that car this year is the World Racing League weekend at BIR in May. The 9-3 will still be the primary car, but the 900 will see action if enough drivers sign on. Saturday's race will be 9 hours, with a 7 hour race on Sunday.

Two drivers with competition experience will join Fart-hinder Racing for the first time at the BIR race. Jeff Gadbois, who has raced competitively in Formula Ford, Spec Racer and Sports 2000 will take to the track after a long time away. Paul Moormann's primary background as a competition driver is behind the wheel of a very fast rally car, a Saab Sonett powered by a 900 turbo engine. In addition, Paul has extensive experience repairing Saabs which will be a valuable asset. Both should be a good fit for the team.

Fart-hinder Racing will once again be a part of the eEuroparts Motorsports Program. eEuroparts.com will share our blog entries with their customers. Cartons of Saab parts from eEuroparts arrive regularly at Fart-hinder Central to keep both Saab race cars, and several street Saabs, running at peak performance.

Hanover European Auto Parts in Hanover, Minnesota, continues to be a major backer of the team. The vast inventory of quality used Saab parts keeps us on track within our meager budget.


But Wait, There's More....

Mark Fitzpatrick has acquired a couple of Mazda Miatas in the past year, and is converting one to meet the rules of ChumpCar and WRL. It is not yet complete, but the roll cage has been installed. It is likely that the Miata (still seeking a good name) will be competing sometime this summer.

Travis McCormick continues to work on his “Molasses” Firebird, and hopes to have the gearbox woes that sidelined it at it's last race sorted out.

Tim has some ideas about replacing the original FHR 900 with another Saab, especially since derelict Saabs seem to keep finding their way to his compound in the hills west of Duluth. That means the 900 race car is for sale, with a large load of spare parts and a complete spare 900 with a freshened engine. It's a great way for a new team to get started in the exciting world of endurance racing.
