Recap: Lemons SF 2008

Wednesday, June 4th, 2008

Its been almost a month and I’ve finally sat down to write a recap of Lemons SF 2008. We entered our trusty #56 Formula BMW E30 with the only changes being the addition of an LSD ($65 from the Pick-n-Pull) and putting in some stiffer springs ($200). We also put in a new (junkyard new that is) left rear hub ($150) to replace the one that led to our crashing out at Thunderhill. All in all we put in 2-3 days of work and we had the car back up and running for well under the $500 limit.

We originally planned to have a Max Mosely mannequin bent over the trunk (pants down of course) but we ran out of time and as you can see the car looked pretty much exactly the way it did at the end of Thunderhill (apart from the aforementioned left rear hub).

Since there was no practice day this time we all just showed up on Saturday and got ready to race. Rob took the first stint and was making excellent progress through the field. It was about an hour into the race when we looked at the scoreboard and realised just how excellent the progress was – WE WERE IN THE LEAD!!!

We were trading back and forth for the lead with car #65 (a green MR2) with our buddies at Team Red Bear just half a lap behind us. Coincidentally all three teams were pitted next to each other making it the fastest section of the pits. The original plan was for each driver to drive stints of 2-2.5 hours so we we immediately knew that something was wrong when Rob pulled into the pits at about the 1.45 mark. It turns out that the heat from the exhaust had literally melted the engine mount which is never a good thing. Luckily we had a spare and we were able to replace it and send Jyri out for the second stint.

At this point we had fallen out of the top ten but we were only about 20 laps down on #64 who was leading. Jyri kept up a steady pace and about 1.30 hours into his stint we had made up a few of the spots when tragedy struck Lemons and driver Court Summerfield died on track. The rest of the days racing was immediately cancelled and we wet to the hotel wondering about the future of Lemons. After battling with it overnight and talking to Courts family, Jay decided to continue on with the race in Court’ memory. The Lemons organizers have organized a memorial fund in Court’ name and I encourage readers to donate what they can. The next morning the organizers made this statement:

A California Highway Patrol investigation was undertaken at the track. The CHP informed us that there was no mechanical failure or unsafe track conditions and that no other cars were involved. The CHP also informed us that, based on physical evidence and witness statements, it appears that the driver was not conscious prior to impact.

The race was now down to 6.5 hours and we had 3 drivers who hadn’t turned the wheel yet. Gabe got to take the start and despite a couple of scary moments kept up decent pace. About 2 hours into his stint he came into the pits for the scheduled driver change when we noticed a crack in the oil pan. At some point the oil pan had struck something on the track and developed a crack that was furiously leaking oil. This was heroic fix time and like last time Rob came up with another winner. He used a drill to drill a small hole in the center of the crack and then used a screw to attach a Gatorade bottle tap filled with red silicone. Amazingly enough this bottletop fix not only lasted over 4 hours at race speed but also took a couple of heavy wall impacts without coming loose.

At this point we were some 60 laps down and had fallen all the way to 37th place. It was time to get back on track and put in steady laps. While that sounded great in theory it was further complicated by our shifter mounts breaking. This meant that the entire drive train would move under braking and resulted in our car popping out of second gear under anything resembling heavy braking. Since there was no time to fix that we just had to drive around the problem and drove the entire lap in 3rd instead. This meant that we were very slow coming out of corners but once we got into the working range of the engine we would take off. This must have confused a lot of our competitors who would come alongside by the midway through the banked turns only to be left behind when the car hit its stride :D It also made the car much more of a momentum car – I found that I could take the esses quite a bit faster than the other cars out there but would usually have to brake to avoid hitting the car in front only for the other car to out accelerate me coming out of the turn.

Guy and I put in some steady laps and which pulled us back into the top 25 before handing off to Rob for the final stint. He putting in some excellent times when someone put him into the wall just 2 laps from the end.

In the end the car went through a lot and kept on running. We finally ended up 20th and were some 50 odd laps behind the winner. The 2 laps we lost in the end were crucial since we were just 2 laps behind Red Bear who finished 18th. All in all it was a fun event though the tragedy did bring home the dangers of racing. Formula BMW will definitely be back for Thunderhill.

Driving in the dark

Tuesday, January 8th, 2008

A few people have asked me what it was like to drive Thunderhill at night and I figured the best way to explain would be to show you what its like. This is a quick lap with no traffic from the 24 Hours of Lemons race in December. Its pretty hard to see the course so I have labeled the corners to give you a better idea of the course.


Driving in the dark from rnair on Vimeo.

As you can see, the visibility is not the greatest which makes driving quite an interesting experience. While the lights do give you some idea of where the apex is, the real problem is in finding your track out point. Turns 1, 2 and 4 were especially difficult since the optimum racing line has a very wide track out point where you run over the outside kerbing on the exit. This is all well and good in the sunshine since you know exactly where you are going and you know that its safe. In the dark however, you simply cannot see the track out point when you turn in and you basically have to hope that the exit is clean and that no one has dumped mud or oil on the kerb. The other problem is that its really quite hard to see the track surface and/or its boundaries, especially when people drag mud onto the track. In many cases, the white line marking the track is completely obscured and you just have to guess at what your turn-in point is and hope that you wont put a wheel off on the inside. Some of this might be improved by using better lights: we used the stock E30 headlights and tried spreading the beam sideways to try and light up the apex but since it is a road car the amount of adjustment allowed was just too limited. The next time we will use more powerful, fully adjustable dune buggy lights instead. My solution to the visibility issues was to take it slow and always leave myself a margin for error, it may not have resulted in ultimate lap times but it meant that I always had enough “in hand” to be able to adapt to the any unexpected changes in the racing surface. Our goal was to just stay out of trouble and rack up the laps at a steady pace – since we were in 6th place after 10 hours I guess it did work :) .

The next video is an example of what happens in low visibility, the cars are just entering turn two after someone had an agricultural moment and dragged a massive amount of mud right onto the racing line. None of us can see the mud on the line and come into the corner at race speed only to lose all grip mid corner. One car spins out completely while dPunks and I have some interesting sideways moments. While I got through it ok, it did give me quite a scare and I ended up taking turn 2 quite slow for the next 3-4 laps. Endurance racers who race at 10/10ths all night must be either incredibly brave or incredibly dumb :-)

The next video is of a couple of laps in traffic. As you can see it is actually easiers to drive in traffic since there are a lot more headlights lighting up the track :-) . Also the headlights make it impossible for someone to sneak up on you which means that you always have a good idea of the cars around you and what they are going to do. This leads to much better manners on the track and less problems off the track. Compared to the October race at Altamont the traffic here was incredibly well behaved and there was hardly any contact.

This final video is a highlights package attempting to show some of the interesting from my 4 hour stint in the dark, I apologize for the crappy editing. All the video in this post was recorded using the PDR100 Racer kit from our sponsors at ChaseCam – I highly recommend it for your own racing/track video.

In 6th place

We just finished the first days racing and we are currently in 6th place just 13 laps behind the leader. Wish us luck for tomorrow.

Frame repair, Lemons style

Sunday, December 23rd, 2007

Bent frame

The cumulative result of all the contact in the Lemons race in Altamont was that the front end of our car was in pretty bad shape. As you can see from the above picture, the left front corner is a couple of inches too high as well as an inch or two inboard of its regular position. Now a real race team would either replace the frame or send the car to a bodyshop for some frame repair. Unfortunately both those options would have put us well past the $500 limit for the race. This is where Robs forklift comes into the picture :-)

We started out by cutting the metal bar that served as our impromptu bumper after the hearse took out our original bumper during the race.

Step 2 was to lower the left edge of the frame. For this we wedged the left frame mounting point of the bumper under a truck and then used the forklift to raise the rest of the car. It took a couple of attempts, and some interesting moments with the forklift on two wheels, but we eventually got the front end into a level position.

Step 3 was to attach chains each of the bumper mount points and use the forklift to widen the front end.

As you can see we ended up moving the right edge over a bit so the final step was to push the right edge back in.

In the end we were able to fix our front end for $0 and keep with in both the rules and the spirit of the 24 Hours of Lemons :-D

The best Lemons video EVER!!!

Saturday, December 8th, 2007

Craig from Group of Fools (Car #9) contacted me a few days ago saying that he had some on-track video from his car that included our car and asked me if I’d like a copy. After being deafened by my “Hell YES!!” he mailed me a DVD with a 10 minute video clip of their car following us around the track.

The following video merges 3 video streams for your viewing pleasure. The top and bottom camera views are from our car (#56 White BMW with a wing)). The camera in the center is from Group of Foolz (#9 Maroon BMW with a baby seat on the top). The video starts with me coming out of the pits to start my Saturday stint and by the 40 second mark you can see the #9 car right on my rear bumper. They then follow us around the track as we both go through slower traffic until they finally pit after about 10 minutes.

Major thanks to both #9 Group of Foolz for sending me the video and ChaseCam for giving us the video setup we used in our car.
