I met Jeff! We actually spent a good portion of the day hanging out, grabbing lunch, talking about differences between Australia and the US. I had a great time hanging out with him (and Mrs. Jeff, who is also fascinating). 

 

 

We ended up missing Mt Washington. As the deadline for the rookie orientation run drew near, we had a hard time getting the car street-legal to bring up to the hill. There were too many little things standing in our way, and not enough time/hands to finish prep, and I had to drop off the roster. We'll have another shot at 2020, and the hope is that we'll have the Datsun available for that.
 
For now, prep continues for Mt Burke at the end of this month.

Shame about mt washington. I'm looking forward to seeing how stock power gets on. I had a supercharged nb for 5 years and recently drove a stock 1.6 and loved it. You always go back to miatas!

We just finished both 2017 Burke 1 and 2017 Burke 2. Race footage is up for both events (I think), but here's a sort of behind-the-scenes video of 2017 Burke 2. Let me know if you guys like seeing this kind of stuff.
 
Now that the car is mostly sorted out, it's getting to be time to circle back on the Datsun!

This was a bit more of a rough event, and was the first time I couldn't drive the car home afterward. I think it also bumped me out of the running for Class Champion this season. I should be able to repair it by Mt Philo next month, but I had really hoped to circle back on the Datsun after this one.

 

Here's race footage from one of my practice runs on Saturday. I'm not committing to corners like I would on race day, but it was still pretty quick. Good enough to be 6 seconds faster than my personal best, when I was pushing as hard as I dared.

It's been awhile since I posted an update, but I ended up winning the P4 class for the year! Philo was a great time, and the weather was incredibly good.

The only problem I had was that CXRacing exhaust manifold. Several of the welds completely failed, and now I need to make a new exhaust for the Racing Beat manifold I bought to replace it. The $400 one lasted one race, and a friend has been racing for two seasons on the $150 RB model. Figures.

Now that the season is finished, I'm working on minor prep jobs ... like heat/defrost, winter tires, etc. The real goal for the winter is to finish up the box truck and get the Datsun ready to race in Spring.

I've never heard anything good about cxracing. Sucks about the manifold.

We've been hard at work getting ready for 2018. The Datsun needed the rear wheel centerline moved back 4" in order to clear the main hoop position. I finally made time to mock up where everything should sit, and finish the rear quarter panel profiles. I think it still looks like a 'natural' location for the rear wheel.

24256608527_e3288573ee_b.jpg
This gives me around 6" of ground clearance with the suspension preloaded, which is perfectly acceptable in my mind. Using 300lb/in springs, that would give me 1500lb of load before things start to go a little wonky. With the pushrod setup that I'm planning on, I can tune it to dynamically increase spring rate toward the 'compressed' end of the cam travel too. 

The cardboard template is reversible, so I can accurately reproduce the profile on the opposite side ... but I may modify the overall shape a bit before pulling a mold.

This configuration puts the fender line quite a bit higher on the body, and I have the option to move it higher or lower if I don't like the way everything sits when finished.

I'm putting off welding the rear suspension in until I have better calculations on what the static ride height needs to be with the stock control arm geometry. I'm probably going to have to move the subframe up a bit in order to keep the ground clearance I talked about earlier, and I can just chop off the OEM front mounts and weld it directly to the X brace if that's the case. It's good to be working on this again.

Sorry I haven't been posting on forums lately. Another episode is live for those who are following, and I've been working on the race support vehicle lately.
 
The new cabin dome light negates the need for headlights

... but the headlights have been significantly upgraded anyway.

We built new swinging doors for the rear to replace the overhead garage-style door, and that meant that we could throw the overhead door tracks and plywood sides away. It's starting to look less like a murdervan back there now.

This weekend, we should have a bit more news on the Datsun, and probably another update on the race support vehicle status. What are you folks more interested in seeing progress on?

The rear subframe is crudely jigged together, and should be ready to rock in the morning. Centering it, defining my ride height, and setting the pitch required a lot of braining.

Based on the measurements from a friend, the LCA should be at a ~14 degree layback. I'm at 13.75 degrees on both sides, and have decided to call that good. At some point, I'm going to move the arm pickup points anyway, so this'll have to do to get me started.

I spent some more time working on my box truck today, and removed the remaining murderwall plywood then reorganized, straightened, and bolted down everything else back there. The etrack on the floor will probably end up on my trailer, but it could make its way to the walls after I've insulated and recovered them. We'll see how it plays out, but either way I love that stuff.

The driver's seat is finally getting replaced. I don't know if I already mentioned it, but the roofing tar in this thing got EVERYWHERE. The seat was disgusting. My favorite caption I've seen so far:

I'll take any update. The box truck is rad too!

It's all part of the same hillclimb package. The basic plan for my season is:

  • NA8C Miata - Finish the exhaust and install the new seat, daily drive that while the Datsun is in progress. Most likely race it for the first half of the season
  • e350 Race Support Vehicle - Tow the trailer, move projects to/from the shop.
  • Open Trailer - Haul the Datsun around, primarily to/from events.
  • Datsun s30 (shaped vehicle) - Get it to rolling, then start adding running gear and seats. Hopefully tow it to a couple autocrosses for shakedown, then to some hillclimbs for real shakedown later in the season.
  • Pit Bike - Live in the box truck, haul me to/from the pits at events.

I've found that the trick is to never put it into the body shop. Leave it ugly, and live a happy life!
