Car Prep Day 3 – Its alive

Sunday, October 7th, 2007

Day three of car prep was all about getting the engine running. At this point we had had the car with us for several months but we hadn’t yet heard the damn thing run.

We started up by tightening up the head bolts and putting in a new timing belt. After that we adjusted the valve spacing (space between camshaft and valve stem) and began reconnecting that various fuel hoses and wires. We decided not to put the cooling system in until the engine was in running condition to give ourselves some work room in case we needed to replace any additional parts. After everything was connected back up we added some more oil to the engine and started it for the first time.

After sorting out some initial issues with some blown fuses, the car started on just the second attempt. The cloud of smoke on the side was a combination of an untightened exhaust manifold and some oil burning off. After this major success we decided to wrap up the day and were actually able to drive the car outside to park it. It still doesn’t have a cooling system so we havent run it for any length of time but the fact that it moves under its own power and doesn’t make any weird noises is a great sign.

3 wheeling GTI

Saturday, September 29th, 2007

Last weekend Nithya and I took our GTI to the GGLC Autocross at the Marina airport. The performance far exceeded my expectations and at 61.7 seconds I was actually the 3rd fastest driver in very wet morning session (the fastest Elise did a 64.x). Much of this was due to the fact that it had proper wet weather tires on, but the handling was pretty amazing – very predictable with some understeer at the limit. It did of course feel quite a bit heavier than the Elise but the direction changes were quick and chassis was very forgiving. As the track dried out I lost my performance advantage over the elises but as you can see in the photo I did manage to get a wheel off the ground :-D

This was also the first Autcross for Nithya as a driver. She started out very slowly with a 130 second lap but by the end of the day she was down 66 seconds – by far the greatest improvement of any driver at the event ans just 6 seconds off my best lap. She had so much fun that she’d decided to attend all future events, we’ve already signed up for the November event. The following video is of her last run – notice the tire squeal in the turns and the cones she destroys near the end :-)

Car Preparation – Day 2

Saturday, September 29th, 2007

Day 2 of preparation was all about fixing up the head. As you can see below the valves were in really bad shape and all of them had to be replaced. We cleaned the head and the block before putting on a new head gasket kit.

The manifolds were bolted back onto the head and we put the head back onto the car. At this point we were feeling quite optimistic about getting the car done when we realized that we didn’t have the right tool to tighten the head bolts – seeing that it was already late we called it quits for day 2 with the head just sitting on the block.

Car Preparation – Day 1

Friday, September 28th, 2007

Now that we had the car at Dietsch Werks, we had to figure out what was wrong with. Day 1 would be all about stripping the car under Robs guidance. We started out by jacking it up and draining the coolant.

The next step was to remove the cylinder head. This was needed because the 325 is an interference engine and the broken timing belt guarantees that we have belt some valves. We disconnected all the hoses + wiring and used a forklift to lift the head out of the engine bay.

Lifting the head

Once we pulled the head off we made a surprising discovery – all the pistons had valve marks on them. This confused us for a bit until we looked at the timing belt and found that it was not only broken but was also missing several teeth. In a regular timing belt break you usually damage the valves in only one or two cylinders before the engine stops turning and prevents further damage. In this particular instance the engine had kept on running with bad timing (due to the missing belt teeth) and ALL the valves had made at least some contact with the pistons.

Marks from the valves hitting the pistons

While all this work was being done on the engine we got to work stripping the interior of the car and by the end of the day it was looking much more like a racecar.

After this we called it quits for the day and felt quite pleased at having accomplished quite a lot on our first work day.

Car Pickup

Friday, September 28th, 2007

After a couple of weeks of frantic paper writing things have finally cooled down enough that I can go back to writing my blog. First on the list is a series of blog posts about our preparation for the 24 hours of Lemons. Sit back and enjoy the fun. :-)

The first and most important thing we needed to run in the Lemons was a car, not just any car, but a car that we’d be able to buy AND prep for for under $500. Looking through the results of the first race we decided that an older japanese econobox would probably be the best car to run with. We were all set to rummage through the local junkyard when fate suddenly dropped a car in our lap. One of Robs friends had an old BMW with a broken timing belt that was blocking his driveway – he told us that as long as we get the car out of his way immediately we could keep the car for free. We quickly showed up at his door to take a look at the car.

We found that the car was a 4 door 1986 BMW 325 E with 245 thousand miles on the clock. The E denoted that it had the economy engine, this meant lower horsepower but higher torque which should be ideal for the tight Altamont circuit. The car itself was in better shape that I expected, the paint was peeling from 21 years of exposure and he interior was a mess but there was very little rust and the engine “looked” ok with the timing belt being the only obvious problem. Being an E30 meant that the parts were cheap and bolt-in rollcages were readily available. People who had entered the last race had warned us that non-running cars were a huge time sink, but the fact that the car was available and free meant that there was only one thing to do. We rolled the car into Robs trailer and made it our official entry into the Lemons race.

P.S.: We are not cheating by getting a “free” car, the KBB value for a 1986 325E in fair condition is $400 – a non-running car is worth almost nothing.

It’s alive

Wednesday, September 5th, 2007

On Monday we finally got our Lemons car started for the first time – still need to put the cooling system on buts its a relief to finally get it running. I promise I’ll have a series of posts about the actual prep work.

P.S.: The smoke is just oil smoke and the unbolted exhaust – the video got cut off because my phone died on me :(

We’re in!

Sunday, August 19th, 2007

I am a huge fan of the 24 Hours of Lemons and am glad to announce that Team SFF1 has officially been accepted into the Arse-Freeze-Apalooza race to be held in Alatamont on 20-21 October. My co-drivers will be Guy Argo, Rob Dietsch, Gabriel Matus and Jyri Virkki. Since we are going to be racing an 1986 MW 325E we decided to go for a BMW F1 based team concept. Check out our accepted team concept and application:

Team Name
SFF1 BMW Sauber

Vechicle Make & model:
2008 BMW Sauber F1.08 aka renovated 1986 BMW 325 E with a broken timing belt and bent valves

Team Concept
After a fast, though unreliable, start to the 2007 Formula 1 championship, the BMW Sauber F1 team has decided that they need additional preseason testing to properly prepare the 2008 F1 car. After developing the initial chassis in secret, the SFF1 test team has been entrusted with performing much needed endurace testing by entering the car in the prestigious 24 hours of Lemons race. With a team of internationally reknowned drivers and backed by a full works pitcrew, the SFF1 team is expected to both compete successfully and gain valuable data to help the car compete for the 2008 F1 season.

Team Drivers
Guy Argo

Guy Argo
In Jim Clark and Jackie Stewart, Scotland has produced two of the greatest drivers to ever race in Formula 1. However after the heady days of the sixties and seventies there haven’t been any true scottish champions – Guy Argo should change all that. He started autocrossing two months after getting his license and one month after taking delivery of his ‘92 special edition Mazda Miata. Two months later he won his first autocross. He started indoor go-karting in 2000 and became part of the famous trio (Guy Argo, David Canavan, Paul Smyth) that dominated F1Boston’s indoor racing scene. In 2002 he transitioned to outdoor karts with a sponsored ride for All Kart. He took a brief hiatus after moving to the Bay Area. But as soon as gokartracer.com opened up, he was already making his mark on the Pro League with several podiums and an outright season win. Currently you can find him testing his mettle against all comers atthe Sunday Night Leagues LeManKarting.com in Fremont alongside his protege, Jay Gopal. Reknowned for his patience, cunning and spectacular passing, what he lacks in speed he makes up for in consistency and determination. We await his return to outdoor racing with bated breath.

Robert Dietsch

Robert Dietsch
Rob Dietsch has been involved in motorsport since the late 80’s doing a variety of AutoX and HPDE before graduating to club racing. After winning the SCCA SFR GT4 championship in his rookie year (2003) he progessed to Toyota Atlantic and had a fairly good season before taking a sabbatical from racing. Currently tracking his Lotus Elise and Porsche Cayman at NorCal HPDE, he has been tempted back to the world of competitve motorsport by the chance to go after the ultimate prize – the 24 hours of Lemons.

Gabriel Matus

Gabriel Matus
With the exit of Juan Pablo Montoya, F1 needs another Latin heathrob to bring F1 to Latin America. With his playboy looks and fierce racing determination, Gabriel has all the ingredients needed to become the next Latino Superstar of Formula 1. One of the main organizers behind the SFF1 group, his endurance driving experience includes commuting from San Francisco to Sunnyvale everyday.

Rahul Nair

Rahul Nair
1 billion people and the best India can come up with Narain Kartikeyan??? Rahul Nair expects to redress that balance by merging raw speed with tactical brilliance to become the first Indian to win in F1. This speed freak can spends as much of his life behind the wheel as he can. He has 2 years of HPDE and Autocross experience in his Lotus and is a regular fixture in the bay area go-kart tracks.

Jyri Virkki

Jyri Virkki
Where would any F1 team be without a “Flying Finn”? Jyri brings with him the same ice-cool personality that saw Keke Rosberg, Mika Hakkinen and Kimi Raikkonen win dozens of F1 races and 3 world championships. A Miata addict, he has been running track events since the mid-90s and instructing for about 9 years (currently instructing with Miata clubs, Thunderhill Street School and BMWCCA).

24 Hours of Lemons

Sunday, July 8th, 2007


I’ve been very interested in the 24 Hours of Lemons since I first heard about it last year and when I found out that the first race of the year was this past weekend I just had to go check it out. The Altamont Motorsports Park in Tracy, CA is the home of the race and features two ovals which are interconnected to create a road-course for the Lemons race. The cars all had to be bought and race prepped for under $500 (excluding safety gear) with a team of 4-6 drivers. Despite the name the actual racing would only go on for about 14 hours with a 10 hour break at night to let people recuperate as well as repair their cars.

Wheel of Misfortune
I got there just as the drivers meeting got underway and found that it was pretty well organized. The organizers were very strict about a no bumping/no blocking rule and had come up with a set of humourous punishments for the drivers that broke the rules. The competitors would spin the “Wheel of Misfortune” and have to serve whatever penalty that came up. Some of the penalties included:

  • The Al Gore Carbon Replacement penalty: The competitor would have to wear a tie-die shirt and then plant a rather large sapling in the ground before they could continue.
  • The Colonel Sanders where the participant would be doused in soapy water and then feathered using large pillows.
  • The Legion of Odour involved hanging a half pound of smelly blue cheese around the drivers neck as well as placing another pound of it on the hot intake manifold – should make for a truly odourous experience.
  • The Egg Man winner (or loser) would have an open bucket of eggs welded to the hood of their cars – the idea being that as they drove the eggs would fall out of the bucket and smear the car.
  • My favourite was the Highway 17 penalty where the driver would have to follow a VW microbus around the track for 10 laps.
  • Anyone who bumped other cars on the track would initially have a set of training wheels welded to the sides of their cars
  • Repeat “bumpers” would get the Sword of Damocles penalty where a plate with sharpened spikes would be welded to their radiator with the spikes pointing inwards. At this point they were let out on track knowing that their next bump would be their last.

The organizers required that the drivers have some sort of competition license and the racetrack was more than happy to sell you a NASCAR license at the gate for just $75 dollars. The fact that people could buy licenses at the door was the main factor that dissuaded me from running the Lemons race last year – after all who want to be side by side with a novice driver in a $500 car. However it looked like the penalties did a good job of keeping the track action pretty clean – the serious racer didn’t want to lose the time while the joyriders didn’t want the embarrassment. The speeds are low as well which keeps the event pretty safe. One of the teams was racing an 80’s Golf which went into the tirewall and flipped onto its roof. The track was immediately red flagged and the safety vehicles were at the car in under 5 minutes. The driver was completely unhurt and with the help of the marshal he roled the car back onto its wheels before continuing with the race :-) .

All in all it was a great event and I am seriously trying to get an official SFF1 entry together for the October race (UPDATE: We just got accepted into the October event) – wish me luck. In the meantime you can look at a video I shot as well as some photos of my favourite cars. I have posted the full collection of photos on Flickr though you will probably be better off looking at the excellent photoset that Nithya just posted.

One lap of Reno-Fernley Raceway (N95 video)

Wednesday, May 30th, 2007


Lap of Reno-Fernley Raceway (Nokia N95) from rnair on Vimeo

I finally got around to editing and uploading some of the video* I recorded during my last trackday. This was the first time I was using the Nokia N95 and I had high expectations from the high-rez camera. As you can see over here the video quality is dramatically better than my past recordings from the N73. I have been planning on getting a ChaseCam PDR setup for a while but now that I can get such excellent video from the phone I think I will stick to my homebrew cellphone setup. There are still some issues with vibration on the high speed straights but I am confident that I can fix that adding a layer of padding (tissue/cloth) to the phone before taping it to the car.

*This video is only to show quality of the recording – the driving still needs some work :)
