October 6, 2004:
I had neglected to put a lock nut on my tie rods.
Yes, yes, I know. There was a little bit of slop that has now been removed.

October 7, 2004:
A few folks have reminded me that CMC sells a windscreen designed for these cars.
It's $300. Not a bad option, but I'm going to try my own instead. I want a slightly different shape than CMC uses and I don't mind putting a bit of time in. It should be surprisingly affordable - the first quote on glass (flat glass, about 35"x15") is $36. All I need to do is find some channel to run around the outside edge. I'll be visiting a few likely suppliers this afternoon. I'll also be dropping by a friend's house as he is donating the wiper setup from an MG Midget. Excellent news!

After this burst of activity, the Seven will sit quiet for a while. I'm heading back to Ottawa for a week and a half to attend a friend's wedding and visit family. I'll also be borrowing an original Mini while I'm there and I'll have a little peek at the wiper setup...

Last night I paid a visit to an MG Midget that is getting a few upgrades.
The owner was planning to remove the wipers so I helped him out! It's not quite a complete setup, missing the flexible rod and with one damaged "wheelbox", but it's a very good start. A bit of looking around a Series III Land Rover and/or eBay will turn up the rest of what I need quite quickly I hope. The motor is heavy!

Back from Ottawa!
I have a track day scheduled this weekend at the Pueblo track. This is a real track so it should be a good test of both the high-speed behaviour of the car and of my nerve. My Miata with this same engine was pulling just about 100 mph at the end of the straight a few years back. I'm quite excited about this as it will give me lots of time to learn more about the car, do some tuning and grin so hard my face will hurt.

To get ready for the track, I have a bit of work to do. Let's see, check the fuel filter, do a little engine tuning, swap over to race rubber, change a few electrical connectors and generally check over the car.

For those who miss the chaos and quick updates of the early summer, there are several other builds that are interesting to watch. I've mentioned Heikki's build in the past. Steve Carter has a website about his Toyotus, a CMC "Classic" build. Hmm, those shipping photos look familiar. Dennis Palatov runs DPcars.net which not only includes the story of building and driving a Hyabusa Westfield in the Past section, but also building his own highly ambitious car from scratch. Judging by the amount of email that's coming my way, my own particular build has caught people's attention.

A suggestion from "Gasoline Fumes" on the GRM forum on how I can transport the Seven!

I spent a bit of time last night prepping the car for the track.
The race tires are very, very close to the rear fenders. Close enough that I thought it prudent to shave a bit off the passenger's side. My modified fender stay is pretty close in the front as well but those parts don't move relative to each other. A quick blast around the block told me two things - the car's a bit unhappy when cold and there's still a bad crimp in the wiring. These may be related but I don't think so as the car did smooth out as it warmed. It turns out that a number of the crimp connectors I used have a problem. Oh yay. I have some spares with me and I'll fix this one before I go. Otherwise, the car's looking good. The track is about 5-6 hours from here so I'll have a lot of spare parts with me just in case! I don't think I'll be taking any video but I will get some good photos of the car in action. Then it's time to continue with hunting down wipers and making a windshield.

Track day at Pueblo!
Long...
I almost didn't go to the track day. Between a borrowed trailer, a borrowed tow vehicle, mismatched trailer wiring, no trailer ramps, a winter storm in the mountains and just overall confusion, I was starting to get the feeling I wasn't really supposed to go. When the Seven died in the middle of the street as I tried to load it on to the trailer, I was close to just calling the whole thing off. Once I discovered that the only problem with the car was an empty gas tank, things started to come together very quickly. To protect the car in the snow (yes, snow) I wrapped the seats in plastic and just hoped for the best. There was some slow going through Monarch Pass with blowing snow and some slippery pavement but I made it. Having a lightweight car on a lightweight trailer certainly helped - the Grand Cherokee I was using for a tow vehicle didn't even notice the load. A big thanks to my girlfriend Janel for trusting me with her "little princess"! Even the goofy outside temperature indicator was helpful as I tried to determine if the road was wet or just icy.

I usually drive to the track instead of trailering unless I'm crewing for the Flyin' Miata race team. Since I was towing this time, my crew instincts kicked in. The back of the Jeep was full of spare tires, brake fluid, alignment tools, electrical parts, fuel line clamps, an air tank, lots of oil, jackstands, a race jack, tools, more tools - and there was 10 gallons of extra gas on the trailer. Did I need all of this? No, but a few other people did as I helped out with various problems over the day.

What about the Seven? I'm getting there, be patient. This track day was at Pueblo Motorsports Park and run by the Peak to Peak Miata club. It's very informal, with no cornerworkers and no run groups. We had perhaps 12 cars in attendance. It's a perfect setup for shaking down a new car, as with only a few cars on the track at any given time, you have lots of room to go quickly or slowly. Everyone is very smart about their driving - unlike the carnage I witnessed at Laguna Seca a few weeks ago, almost everyone stayed on the track. The worst casualty was a new Mazdaspeed Miata that slid off sideways and popped a couple of tires off the wheels. In all, an excellent group to share a track with. I was the only person who wasn't in a Miata.

Okay, the Seven. After cleaning the poor dirty thing off a bit, I went went to reaquaint myself with the track. It's not a world-class track but it is entertaining enough and has a couple of spots that do demand a certain level of confidence. Checking the tires on the first return to the pits, it was obvious that I wasn't using the inside of the front tires. I popped off the upper control arms and put in a bit more negative camber. That seemed to help, planting the front end better in the fast sweepers and accentuating the car's turn-in. The overall balance seemed excellent so I started to bring up the pace.

Last time I was here, I had a good time playing with Dave. I had a bit more power but he was quicker through the tight sections. Over the past couple of years, he's put a lot of work into his Miata including some 235-series Hoosier tires and an engine transplant. He took me out for a ride and it became immediately apparant that I was just goofing around on the track. He was far more committed and much faster. So I went back out and turned up the heat a little. Dave came out at the same time and we were an almost perfect match in lap times. I still couldn't match his commitment through turns 2 and 3 but I did find myself running up on him on the front straight. That surprised me because of the car's aerodynamics. We had a good time chasing each other around and there was a turbo Miata that was also quite quick.

I'm not sure just how fast I was going on the front straight, but I did see 5300 rpm in 5th at one point. That's about 103 mph according to my calculations based on tire size. It was fast enough that my helmet was starting to generate some real lift and I was being beaten pretty hard. I'd always thought that aerodynamic helmets were a bit of an affectation but I've changed my mind! I also ended up duct-taping the hood shut to stop the lifting at these speeds. I need some louvres in the hood.

The rest of the day was spent just playing. The car proved hugely entertaining and very quick, flattering my driving to no end. Coming out of turn 7, I had the option of hitting a line on the inside that would pull me around like the Carousel at the 'Ring or going a bit wider and just painting a pair of big black stripes on the pavement as I accelerated. The latter was obviously the fun choice. Turns 5, 6a and 6b fwere much faster than they appeared thanks to a nice compression and a smooth line. I'm still a chicken about hard braking but that's not the car's fault. The Seven ran cool and without complaint. The exhaust is not all that subtle at full throttle and after spending the entire day at 6000+ rpm, I was regretting my lack of earplugs. It's a perfect race car sound with a little crackle when I blip the throttle at idle. I was thinking about quick-ratio steering racks that are so popular amongst the Caterham/Westfield community. I'm not sure why - there's certainly no room for flailing elbows in a Seven cockpit but I like the ratio of my own. Good thing that's what I own then!

It wasn't a perfect day, though. On my last session, I noticed the clutch pedal was starting to feel a little odd. At the end of the straight on the same lap, nothing. No clutch. I managed to match revs well enough to throw it into third (while entering turn 1 at a high rate of speed) and limped back into the pits with a terribly slipping clutch. I could just maintain speed. By the time I got to the pits, the clutch pedal was moving freely. A peek under the car showed a puddle of clutch fluid below the slave cylinder. My theory is that I had too much clutch pedal travel and was moving the master cylinder too far (something I'd been meaning to change). The high pressure on the system every time I changed gears eventually blew the slave cylinder seals. I hope so - that's an easy fix. I was ready to leave anyhow so we just pushed the car onto the trailer and it's sitting in the garage now.

I'm a little sore but really glad I made the effort to go. It was a great day. There's just one problem: I jumped into my Miata this morning to move it and the brakes felt so soft, the steering numb and the clutch too light...

The far less entertaining reality.
A borrowed snowmobile trailer and a borrowed Jeep. Note the plastic wrap in an attempt to keep the seats dry in the snow!
entry 640
Although the Seven uses Miata mechanicals, it doesn't wear a Miata car cover very well.
entry 641
Yuk.
While the seats stayed dry through the snow, the rest of the car was covered in road goo. The roll bar, the steering wheel, the scuttle and the transmission tunnel were all covered. How did this car get so dirty so soon?
entry 642
They don't call it "racer tape" for nothing! This was a successful attempt to keep the hood from bulging at speed.
entry 643
Out on the track.
entry 644
Alignment changes in the "pits".
entry 645
Some of the other participants.
Stock Miatas, turbocharged Miatas, supercharged Miatas - everyone very consistent to drive around and a pleasure to share a track with.
entry 646
It's difficult to tell, but this is hard braking.
Not much dive.
entry 647
Dave proves to yet another passenger that they drive like a wuss.
Like he did with me. In exchange, we made fun of his lowrider slicks.
entry 648
After my ride with Dave, I went faster.
Thanks to Geremy Kornreich for taking this and other shots of the car in motion!
entry 649
The front straight.
Does it look like a drag strip? It is. Geremy took this photo with his arms in the air - your sightline is usually a little lower.
entry 650
Yours truly, grinning like a madman under the helmet.
entry 651
Hard at play.
