Last-Minute Laps

Update by Per Schroeder to the LeGrand Mk 18 project car
Aug 25, 2011

On the line, waiting for the launch signal. We needed a fair amount of revs to get going without bogging.
The finish was pretty fast, with a shift into third gear before the lights.
Up on jackstands in our garage.
Prospeed RS683 brake fluid: good for high temps and a firm pedal.
The Phoenix Systems DIY reverse brake bleeder works great.

We towed up to Whitehouse Airfield for a Buccaneer Region Solo event and had a blast.

We’re always a little nervous at the events leading up to the National Championships. At this point, if anything broke, we’d be pretty messed up and wouldn’t make it to the big show. On the other hand, getting some seat time and additional shakedown time is also important—especially if you’ve driven as little as we have this season.

We towed up to Whitehouse Airfield for a Buccaneer Region Solo event and had a blast. The site features some of the best concrete we’ve ever raced on. In fact, the only fault that we find with the site is that it’s too good—giving more grip than we’ll actually see in Nebraska.

Our runs went well—we tried a variety of lines through some turnarounds and slaloms to see how the car would handle in various situations. At the end of the day, we posted the FTD for the event and second on index.

Video of our runs can be seen here:

When we got the car back home to our shop, we put it up on jackstands and removed the wheels and tires. We’ve got fresh new rubber for Nationals that needs to be mounted up.

We also took the time to flush our brake system and change the fluid. We had great luck with Prospeed RS683 brake fluid in our brake pad comparison story and decided it would be a great addition to this project. We used a new DIY brake-bleeding tool from Phoenix systems that quickly flushed and bled our system—in less than 10 minutes.

Two things:

  1. Once the old fluid goes back up to the reservoir, how are you getting it out?

  2. Do not sell this car. It's a part of your family history. Sell it to your dad maybe but I guarantee you will regret it if you let this one go.

  1. Good question. I started with an empty no issues--i just siphoned it out...and resiphoned when it filled up with old fluid from the lines.

  2. Yep. Just need to find a bigger garage.

When you get back to Florida, you should check out the 3 most recent issues of Racecar Engineering. They have been doing some studies of sports racer aerodynamics. May give you some ideas for future work.
