Setting up a Seven – Road trip to WCLM 2013

One of things that I’ve always wanted to do in the Seven was go on a long road trip. However I’ve always been afraid of mechanical breakdowns which is why I took the Elise to LOG 31 in Vegas two years ago. Once the 2013 West Coast Lotus meet was announced for Seattle in July, I started toying with the idea of taking the Seven but kept prepping both cars so that I could make a last minute decision. As luck would have it I was changing the oil on the Elise a couple of days before the trip and found a transmission leak which meant that the Seven was now the only option for the 2000 mile trip.

I started checking weather forecasts along the route and thankfully it appeared to be little chance of rain which is a good thing in a roof/door/window/windshield-less car with potentially dodgy electrics. I did see that a heat wave was expected with temperatures in excess of 100F but having done a 98F trip down to Buttonwillow in the past I felt pretty confident that I would be able to handle it with my cool suit. In terms of mechanical reliability I had driven the car several hundred street miles in the past few months which made me feel good about making it to Seattle without an issue. The risky bit would be the track day at Pacific Raceway but if a terminal issue cropped up Rob @ DiestchWerks said he would be able to trailer it back on his race trailer if needed. With all this worked out I decided to take the Seven on an epic roadtrip.

Epic road trip begins

I started out with fellow Ultralite owner and GGLC member Jim R who was going to drive up with me till Shasta City. We started out at 7 am as I wanted to cover as much ground as possible before sunset and had set myself the goal of reaching Medford at the very least with Eugene as a stretch goal. Since the planed distance was only just over 400 miles, we even took a slightly longer route to get the obligatory pic with the Golden Gate Bridge just like my last trip tor WCLM 08.

Required photo op

The first couple of hours went quite well and we covered 100+ miles before it warmed up enough that I had to start up the cool shirt which is basically a shirt which pumps cold water through it to keep the wearer cool. They were originally designed for surgeons but are now used by firemen, military, hazmat and of course racing. I originally picked up a cool shirt to use it in Lemons racing but after I got the Seven I realised that it was the perfect way to stay cool in the car as well. Jim and I made it up to Shasta Lake before stopping for a bite to eat at the Basshole Bar & Grill in Lakeshore CA just after noon.

By this time the time the mercury was really rising and Jim decided to head home while I continued on to towards Oregon. As I entered the mountains below Mt Shasta the weather was quite pleasant (though assisted by the Cool Shirt :)) and I was feeling quite good about my progress for the day. That came to crashing halt as I got passed the mountains and entered Oregon where the weather really shot up. The temperatures in Ashland were well above 100F (Jim saw 108F at one point on his way back) and it was so hot that I literally just pulled off the highway and parked under a tree.

Heat break

At this point the ice cooler part in the Cool Shirt came in handy as it meant that I had some cold refreshments to help cool myself down. I then decided to try driving a little bit without my helmet on but the hot air hitting me in the face made it hard to breathe so I put the helmet back on and kept going in short 30 min stretches. By around 5 pm the temps started dropping and by the time I got to Eugene at 6 it was pleasant enough that I took the helmet off off and cruised up to Salem, OR where I spent the night. The next day I was up and running again and made it to Seattle despite some extreme heat and traffic in the Olympia area. My dash got so hot at one point that my phone overheated and shut down. In the end I did make it to Seattle with the car running like a champ with only the organic bit behind the wheel having issues with the heat (see below). BTW if you think I’m complaining too much about the heat, it was so bad that the WDOT had to shut down a bridge and water its deck to prevent excessive heat expansion.

This is what 850 miles in 100 degree weather looks like

The first official event at the West Coast Lotus meet was a track day at Pacific Raceways which was put on by the folks at ProFormance Racing School. We started out with some lead-follow laps as most of us had never driven the track before. Pacific Raceway is a fairly technical track with 350 feet of elevation change which means you have a lot of blind late apex corners. Plus the track is very different from my usual tracks with very little run-off or exit kerbing and plenty of surrounding greenery – it feels more like a hillclimb course instead of a closed circuit track.

After a few sighter laps and some conversations with the instructors I was able to work out a reasonable line and really got into the groove at the track. As you can see from the video below I was not pushing very hard as I did not want to break anything at the track. One thing to note is that I did discover that top speed on my car is 125 mph which I hit 2/3rd of the way down the looong straight – it was actually a bit disappointing as I thought that the Seven was a bit faster than that but I guess crappy aero performance really does take its toll. We did have a modified Elise (slicks, 300 hp, sequential gearbox, paddleshift) that was quite a bit faster and was hitting 140 mph down the same straight.

The most interesting moment of the video above was when I go off at the 14:20 mark. This was due to a stuck throttle though luckily it was stuck partially open and not at full throttle. I didnt realise this initially as the revs do go down when I get off the gas but the car did not slow down enough. I keep adding more brake pressure and end up locking the front wheels before I go off the course. At this point I go both feet in and the engine revs rise to ~4k rpm and I realise what the problem was. I was able to use partial clutch to get into the pits and killed the engine as soon as I got in. When I opened the hood I found that the bracket that the external throttle release spring attached to had broken off and the stock throttle spring was not strong enough to close it all the way which is why the engine was stuck at part throttle. I was able to ziptie the spring back together to get the car going again but called it quits for the track day as I didnt want to risk it happening again on course.

Went off with a broken throttle return supporting bracket. Back running with a quick ziptie fix

After the track day I headed over to the event hotel which had organized some excellent “Lotus Parking” for the duration of the event. This meant that we not only got to see the cars all together, but we also got to chat with all the owners as we came in and out of the lot. After the cocktails and reception many of us headed out into the parking lot to check out the cars and shoot the breeze with other Lotus fans.

Lotus everywhere

Day 2 started with an excellent tour of Paul Allens Flying Heritage Collection. Nothing to do with Lotus but it is an excellent collection of WW2 era machinery including airplanes, rockets and tanks. Many of the airplanes are still airworthy and are flown a few times a year. Its also right next to the Boeing Dreamliner factory where a bunch of planes were getting fitted for their customers. I highly recommend it for anyone who likes mechanical objects.

In the afternoon we headed over to the parking lot of Bellevue Community college for the WCLM autocross. It was a very tight course that you lapped multiple times to set a time. Most people were doing the course in first gear though due to my low gearing I was able to launch and do the entire run in second gear instead. The following video is of my 31.165 second run which ended up as the top time of the event. I was even able to avoid hitting “my cone” which folks were taking odds on whether I would hit it. Facebook users can see more photos from the autocross at the WCLM FB album

After the autocross we headed over to the Snoqualamie Casino where we had an excellent buffet dinner along with drinks on the roof right in the shadow of the mountains. Plus it was another great chance to check out the cars and we got a lot of regular casino guests coming by to ogle at the cars.

WCLM Dinner

I was feeling a bit under the weather on day 3 so I skipped the SOVREN Historic Races and the parade laps at Pacific Raceway. I directly went over to the LeMay museum in the afternoon where we were taking a group photograph before dinner and a private tour of the museum itself. The album below shows some of the cars on display in the museum, as well as some shots of the cars lined up for the group photo. Another wonderful place to attend and much better organized than the original warehouses that they used when I first visited the LeMay in 2010. After the LeMay trip I was hanging out with some Canadian attendees at the hotel who were quite surprised to learn that I had driven the Seven all the way from CA. Hopefully at the next WCLM we can have a some of them drive all the from Canada instead ;-)

The final stop on the WLCM calendar was at the Griots Garage retail store in Tacoma where we got look at some of their cars and also got a demonstration of their car car products. Not very Lotus specific, but they are definitely car guys as evidenced by their McLaren display below. I have to say that Doug and the ELCC really put on a great WCLM and are going to get a lot of repeat business the next time they host a WCLM.

McLaren

After lunch I headed out around 2pm with the goal of making it back to Eugene, OR before nightfall. The return trip was going well until I stopped just before the WA-OR border and noticed that the left side of the car was covered with coolant. The upper radiator hose had sprung a leak and was dripping coolant under pressure.

And now we're dumping coolant

I filled it up with some water and Rob @ DiestchWerks a call to see if I could get him to trailer the car back. It ended up he was about 45 minutes ahead of me so I limped the car over there while he stopped at an auto parts to see what he could find. In the end he cut the hose at the point that it was leaking at and used a plastic coupler and some hose clamps to put it back together again. I then got back on the road and started driving with frequent stops to check the coolant levels and to watch for any further leaks. I was able to make it to Canyonville before nightfall and stayed at the Seven Feather Casino which was the site of the WCLM 08.

Spending the night at the home of WCLM 08

I decided to drop my original plan to drive straight down I-5 as the temperatures in the central valley were expected to be well over 100F and I did not want to put additional stress on my cooling system. Instead I took US-199 over from Grants Pass to Eureka and then took 101 all the way to SF. This turned out to be a great decision because though the trip would be longer, it was much much cooler plus US-199 is an fun road to drive in a sports car.

Lunch at the Samoa Cookhouse

After having lunch at the Samoa Cookhouse above, I took the famous Avenue of the Giants route through Humboldt Redwood Park which was another fun detour.

At this point I was far enough inland that it was starting to heat up again and I had to put my cool shirt on again. Plus the temps never went about 95 which meant that the cool suit was able to keep me quite comfortable. I then stopped off to meet a friend in Windsor, CA and was able to avoid much of the evening heat before making the final 90 minute drive back over the Golden Gate Bridge and through SF to get home again.

Home at last

All in all the car ran quite well and apart from the throttle and coolant issues it gave me no trouble at all in over 2000 miles in some blistering heat. I got lots of weird looks and several photos taken of me on my trip but I have to say that it was great fun and I would say that all Seven owners should consider doing at least one long road trip in their cars – it is an experience that you will not forget and you’d be surprised how reliable our cars can be. Now where is WLCM 2014 going to be? :-)

Google Glass needs a Personal Video Loop

I’ve been doing a lot of thinking about Google Glass at the moment and so far I havent seen anything to make me want to rush out and buy a pair (although I reserve judgement till I actually play with one). One of the things getting a lot of attention is the ability to record hands-free video which in my opinion is over-rated. I’m basing this on in-car video recorders (and more recently dashcams) that people have been using to record hands free video while driving for years. I have been using a variety of different setups to capture in-car video over the years and have found that while its very cool at first, it’s quite rare to go back to look at the video. Of the hundreds of hours of video I have collected, I only look at it when there is something specific I needed to check (line, traffic, best lap, etc…) or to see if the video captured something spectacular (spins, passes, accidents, etc…). In general it is quite boring to look at hours of raw video even while doing something as interesting as racing cars on track. As for making edited videos it is a long, slow and difficult process and people wont be bothered to do it once.

What Google Glass really needs is to take a suggestion from the dashcam world and record a continuous loop of video that the user can save after the event to record the important/funny/interesting thing that they just happened to see. It would be a video version of the Personal Audio Loop (paper pdf). A Personal Video Loop if you will.

Imagine being able to immediately save some cute thing thing by your kids/dogs/cats/etc… Instead of remembering to tell Glass to record, it is always recording and you can just tell it to save the last X minutes. Apart from the cute overload videos, the number of dashcam videos on Autoblog and Jalopnik are proof that even the most average people will keep seeing some interesting things. Plus the sousveillance aspect of having cloud-stored video to back up you account of events would be pretty revolutionary as well.

I know there are a bunch of legal (and power) issues around recording video like this but someone should try building it. Glass explorers – start exploring :-)

Circuit of the Americas Facility Review

Michael locks a wheel at T12
I had the pleasure of attending the inaugural Formula 1 US Grand Prix at the Circuit of the Americas last week and want to write up my thoughts after the event. This is not a review of the race itself but rather a review of the venue from a fans point of view and how it compares to other race events I have been to such as IndyCar (Infineon), NASCAR (Infineon) and the 2002 F1 USGP at Indianapolis.

Getting to and from the track
Untitled
Having read nightmare predictions about parking at the race I decided to use the free park and ride shuttle from the Travis Expo center instead of shelling out $200 for a parking pass. I was quite concerned about how long it would take to get to the track but the folks at the shuttle did an excellent time and it took ~10 minutes to park and no more than 15 minutes after that to board the shuttle. The shuttle ride itself took only 20 minutes which means the total time from entering the paring lot to getting to the track was under 45 minutes which is pretty good for a first time event. Once the shuttles drop you off it is a longish walk (~0.75 mile) to the track gates themselves so you are going to want to wear some comfortable shoes.
Walking to COTA

The return trips had a long line to get on the shuttle though once again they were very well organized. Friday was a 10 minute wait with Saturday in the 20 minute range. As expected Sunday was the longest wait at ~45 minutes which again is not that bad when you have 110,000 people trying to leave at the exact same time.

Having spoken to some other folks who took the parking passes it appears that they had zero issues parking and you could have saved a bunch of time by using the pass. I’d recommend getting a pass for $200 and then splitting the cost among 7 people in a minivan :-)

Facilities
The facilities were pretty well laid out and the first thing you saw on entering the track were the large merchandise booths. They were pretty crowded during the day and actually ran out of many items so I’d recommend buying the stuff you want asap on Friday morning (which is when this photo was taken).
Lotus F1 Team Merchandise

There were a lot of food options at the track with things like Outlaw Grill, Po’ Boys, pizza, Krispy Kreme, nachoes, etc… Apart from the pizza and a few vegan tamales the veggie options were a bit thin so you may want to plan for that. The worst problem though was that the lines at every single outlet were soooo long that after day 1 (~60,000 attendance) we just smuggled our own food in as it wasn’t worth it to stand in line for 30+ minutes just to get a burger. The track really needs to get more concessions ready for the next race.

There were a huge number of porta potties lined up right behind the stands and also in the shuttle area which meant that we did not have long rest room lines. The track was also actively trying to improve during the event. People complained about a lack of trash cans in the stands and they brought them in to the stand stairwells for day 2 and 3. All in all the track did a great job serving a huge crowd in their very first year and I am confident that they will only get better next year.

Track Seating
Button Vs Kimi
I was sitting in Sec 9, Row 33 of the T12 stand which put me ~10 feet past the apex of T12. These were the most expensive seats ($500+) in the race and the price was justified by the view. Apart from the excellent view of T12 (above), you could also see turns 13, 14 and 15 up close, turns 5, 6, 7 on the other side of the course and you also had a distant view of turn one though it was too far away to be able to tell which cars were which. One issue with sitting high up was that its too hard to read the text on the big screens (sec 9 is equidistant between 2 screens which exacerbated the problem) which makes it hard to follow the race in details. If I was doing it again I would sit towards the bottom of the T12 stand as you are closer to the cars and the loudspeakers at the bottom will let you follow the race better. Since most of the passing happens at T12 anyway you dont really miss too much by losing the view of the far side of the track. The following video was taken during the installation laps from Sec 9, Row 1 at T12.

Turn 3 was a stand which received rave reviews from the assembled journalists. The painted runoff areas lead to some spectacular photographs and the drivers love the high speed sweepers which are reminiscent of Silverstone. However as a fan I’d rather watch some passing or passing attempts and with only two moves being pulled off at T2 all race I’d suggest sitting in a different stand.

The general admission areas of the track has some spots with excellent views as long as you come early and camp out. The prime spots IMHO were in front of the T15 grand stand (allows you to see down the straight), T19, exit of T20 (great acceleration + view of the podium, pic below) and the entrance of T1 (packed on all 3 days). If you are willing to come in early and camp out I’d suggest doing that as it will save you a lot of money and be a more memorable experience. You can also try going into the tower which gives you a spectacular view of the track but you will likely need binoculars or a long lens to be able to identify cars and follow the action.
Nico & Michael

Finally if you can get access to a PSL seat I’d recommend T15 and T1 as they will allow you to see down the straights which really shows the speed of these cars.

Autograph sessions
Autograph Schedule
The track had autograph sessions for all the drivers but the drivers were there for just 15 minutes which is truly pathetic when you have 110,000 paying fans at the event. FOM should really force all drivers to have at least a 30 minutes session and extend it to an hour for the more popular teams and drivers (Red Bull, Ferrari, McLaren, Kimi, Schumacher, etc…). Compare this to NASCAR and Indycar where you can get a garage pass and chat with the drivers, F1 is extraordinarily fan unfriendly. As a friend of mine said later – welcome to F1 where the fans come last.

Driver identification
Once other thing that F1 really needs to learn from NASCAR is in easy identification of the drivers. While the cars themselves are very easy to identify, it is almost impossible to tell the team mates apart. Some drivers use very different helmets (Michael and Nico, Alonso and Massa) which make them easy to identify but to many of the team mates use helmets that are too similar to differentiate at 100 mph from 20 meters away. And to top it off people like Hamilton and Vettel actually changed their helmet on each day of the race which made them even harder to identify. The only team with a clearly readable number on the car was McLaren. Even the HRTs which have a large number of the car have put the significant digit on the sidepod such that it is difficult to read(below). FOM should force team mates to have clearly differentiable helmets and also make drivers carry the helmet (or a replica) on the parade lap so that fans can tell who is who.

Fanvision
This is a mobile controller that you can rent for $69 for a weekend and gives you access to multiple video and audio feeds as well as live data statistics. I decided not to get one as I expected to use earplugs the entire weekend which would have made the audio pointless. People around me did have them and the verdict was a little split. Most everyone felt that the video was pretty useless as the screen is quite dim and can barely be seen in direct sunshine. People did use them to get live stats since the intermittent cell service made all the free timing apps very flaky at the track. Those that used the earphones said that they were able to hear the audio and really liked the ability to plug into a drivers radio feed as well. When you spend this much on the race its probably worth spending the extra $70.

Hotels/Flight profiteering
Now I come to the part of the experience that really pissed me off. The rampant profiteering from the hotels and airlines lead to $750 round trip airfares and places like Motel 6 charging $300/night. I understand supply and demand makes rates go up but raping your customers also guarantees zero repeat business. One person I met said that the Austin Crowne Plaza was charging $750 per night with a 4 night minimum when their usual rates are ~$120/night. With ridiculous prices like this the price of a race weekend for a couple from the Bay Area would be well over $6000 ($1100 tickets, $1500 airfare, $3300 hotel) at which point I would rather go for a luxury cruise or drive the Nurburgring instead. This is no fault of the race organizers and is out of their control but is the thing that is making me want to avoid the race in future. Hopefully if the New Jersey race does happen the profiteering wont be as bad since 100,000 people would just be a drop in NYC bucket.

Off-Track Events
One of the best things about attending an F1 race is the number of F1 related off-track activities that take place. The Formula One Team Association (FOTA) held their first american FOTA Fan Forum where 500 fans got to directly interact with team representatives ask the kind of questions you never see on TV. I was unable to attend but will definitely try to attend the next time.

Fans of F1 history also got to attend the world premier of “1: The Unvarnished Story” which charts how safety has improved over the years. The red carpet held at the Paramount theater attracted a host of F1 luminaries like Sir Jackie Stewart, Emerson Fittipaldi, Damon Hill, Bernie Ecclestone, Herbie Blash, Eddie Jordan, Christian Horner and Martin Brundle. I highly recommend watching the movie when it release to the public. The target rich environment was an awesome place to be if you are an autograph seeker :-)
New Autographs

For the more casual fans Austin create the F1 Fan Fest which shut down a 9 square block area of downtown Austin with music, food, stores and all manner of motorsports related activities. Mobil 1 had a tent where fans to do a pit stop on an actual McLaren show car while Red Bull and Lotus show cars were all over the place. If you are staying in a downtown hotel it is well worth a visit to the fan fest.

Bottomline
All-in-all it was an enjoyable experience and I would recommend doing it at least once especially if you have never been to an F1 race before. It is however quite pricey and as a result I’m not sure if I will be going back next year.

Brake Bias Issues

The only major dynamics complaint I had about my Ultralite was the rear lockup issue under hard braking. The car comes with a very nice set of Wilwood brakes (front and rear) with separate master cylinders for the the front and rear so it definitely wasn’t a component quality problem.

The issue I was having is that under hard braking at autocross the rears would immediately lock up and cause a lot of oversteer. This was even worse at the track where braking at the end of straights would lock the rears well before the fronts leading to bad porpoising at the rear. The whole issue was being caused by having equal braking capability front to rear which meant that once the weight transferred forward under braking, the rear wheels had very little weight on them and were prone to locking up while the fronts were still spinning. You could avoid this by braking earlier but this would mean that the front brakes would not be used to their full ability and would lead to longer stopping distances. The real solution would be to move the brake bias forward which I first attempted to do using the balance bar in the pedal box/master cylinder setup. This made no noticeable difference to the brake bias which meant that the bias issue was worse that I suspected.

Step two was to install an inline proportioning valve(below) on the rear circuit which could reduce the rear line pressure by up to 57%. While this did make the autocross situation much better I still had the problem of rear porpoising at the track albeit much better than before.

After consulting with some of the folks on the various forums I came up with two options: 1) replace the brake caliper with a smaller caliper and 2) replace the rear master cylinder with a larger piston. Since the piston was significantly cheaper than getting 2 brake calipers I decided to replace the MC with a 7/8th inch piston (originally 3/4 inch) which has been a great solution so far and has allowed me to run a much more balanced car at the track.

If you are building a car from scratch I would recommend going for a smaller set of calipers in the rear and/or smaller brake rotors both of which will save you some unsprung weight as well. I believe that the later Ultralite owners went to using stock 12-inch Subaru rotors in the rear which sounds like an economical solution as well. If you have a car with the original setup I can say that this solution of larger MC and bias valve has worked well for me.
