There have been two more events since my last post, and I managed first place in both. The latest event I won my class with a 3 second margin. If I make it to enough Miata Club events this year, I'm pretty confident I'll get a season trophy. Not that it's a big deal, since it's just the Miata Club, but despite what I said in my last post, I won't be running any SCCA events this year. I'm saving that money for repairs, for LeMons, for whatever else might come up.

In other news, I finally got access to the Mazda Motorsports (aka Mazdaspeed) online store, with the fancy competition discount. So now I can buy all sorts of OEM parts below list price. I'm going to start with a bunch of Ye Olde Miscellany* that need fixing up, like the stupid plastic joints in the headlight lift mechanism.

Expect several short posts to follow this one; I have many updates, and I don't have necessarily the time to lay out a big narrative to cover it all at once. Get ready for a major blast.

Yes, I skipped a night of welding class to do this (among many other things).

*Amanda insists that I give her credit for this phrase. Here you go.

This book is terrible. (a book review)

I realize the motorsports publishing well might be a little dry of authors, so I can understand if some books by first-time writers aren't very good. Car "enthusiasts" (a polite word for "nerd") may not be the cleverest writers in the world.¹ Take as evidence nearly every article in SportsCar Magazine (basically the SCCA's monthly newsletter, in magazine form), and that Car and Driver, when asking readers for stories to print in their 10Best issue, admitted they rarely received good content and pulled that part of the reader content feature.

But for every interview I've trudged through, every nationals event recap I've skimmed for the few interesting details, every thinly veiled sponsor plug I've dismissed as the cost of business, I never thought I'd get to something quite this awful.

Ross Bentley is a writer who either doesn't understand what "writing to an audience" means, or he thinks he's writing books for 4th grade dropouts who managed to get a driver's licence.

Reading his book, Speed Secrets: Winning Autocross Techniques, is an exercise in repetition. He'll start by telling you something obvious, in broad, almost completely useless terms. Then he'll repeat it, over and over for a page and a half before he says something that truly adds to his point. Then he'll hammer on that for a while. Don't rinse: just repeat.

An example: You're starting Chapter 9, and he just spent the previous chapter covering a few racing lines. This new chapter is titled Priorities, subsection: Prioritizing turns.

"... successful [drivers] know how to prioritize the various turns on a course. Good drivers know where to push hard and where to be patient.
Some corners are more important than others. Winning autocrosses comes from knowing where to go fast and where to go (relatively) slow. .. Concentrate on learning the most important turns first. ... In autocrossing, you will have to compromise one turn's speed for another. ... If you know which corners are most important, you know which ones can be compromised and which ones can't. In terms of your car's setup, there are times when you must compromise the setup to suit one corner more than another. ... It is best to set up the car for the most important corners."

These are lines lifted from 3 consecutive paragraphs. Between the second and third paragraph, in big, bold letters in the middle of the page is a SPEED SECRET. There's a number of these throughout the book, to highlight major points. It's his gimmick. The point of this section, in case you're really a numbskull, is Focus on getting the most important turns right first.

This book does have some good information. It's not completely useless. But it is unreadable, and it's not going to get anyone interested in the sport.

¹ I dispute this idea. Car and Driver (recently, and some years ago), Top Gear (both TV and magazine), and Grassroots Motorsports are proof that there's plenty of good authors out there who are also car guys. Apparently these guys either don't work cheap, or don't write instructional books about racing.

For Your Consideration

I met Andre at an SCCA event earlier this year; we gridded near each other. He's got a very beautiful blue second-gen Miata. His autocross goals are different than mine, but we both have been attacked viciously by the racing monster. We've become good friends. One day we'll be racing 24 Hours of LeMons together, but now it's the off-season and it's time for snow tires and blogging(?)

So, I've added his blog to my newly added blogroll, at the right of the screen. Pay the man a visit.

Raceland header wrap & install

Updates at bottom.
This weekend, I installed a new header in my Miata. I bought one of the very inexpensive ones you can find on eBay, though I went through their Web site. (I also bought a windblocker; details on that later.)
For the incredibly low price of $80, I felt like the Raceland unit (part number RO-HMX5NA-1.6) was worth the gamble. I also bought some generic header wrap on eBay for $25, and a new oxygen sensor on RockAuto.com to accompany this project. This modification is legal in the SCCA's autocross STS class, which means I have nothing to lose.


The installation, unlike nearly every other major project I've taken on, went without a hitch. I had no major difficulties, outside of one bolt I had to snap off. Nothing was too difficult to get at, or too hard to remove. I didn't even have to run back out to the store. It was surprisingly painless. I've heard that the 1.8 liter models have more fitment issues, but everything was fine on my 1.6L engine.


Click the photo above to go directly to my Web photo album. There are some close-up pictures of the header, details and tips for the installation process, and a surprise crack I found in my original header.


It's quieter at cruise than my OEM header (probably thanks to that crack), though it sounds racier at WOT and at higher revs. It's also smoother and stronger in the middle and top end. I won't attribute all of this to the header alone; the new O2 sensor and the wrap probably helped a lot too. All in all, I'm very satisfied. If I had spent $450 on the Racing Beat or Jackson Racing headers, I don't think I would've been as happy. This is a significant improvement for a little price. Kudos, Raceland.

Update: The header wrap didn't seem to like snow very much. http://sentimentalmechanic.blogspot.com/2010/06/this-is-what-happens-larry.html

Update 2: After little more than a year, the thing has rusted -- yes, rusted! -- badly enough to break apart.

Update 3: Raceland honored their 2-year warranty and sent me a new one.

200K Mile Autocross

Last Friday, on the way home from work, my Miata rolled over 200,000 miles.


That weekend, I treated myself to a precision alignment. I went to Archer Alignment in DeKalb. I got the job done on a laser machine, spot on to my specs for a mere $80. The guy was smart and friendly, too. Highly recommended, especially considering many people pay upwards of $150 for a precision, custom alignment. Archer is a deal.


I also recently had to de-power the steering rack due to a bad power steering leak and an inability to find the correct parts (I did it the quick & dirty way). It's a little stiff in parking lots, but otherwise perfectly livable. I was, however, somewhat concerned about steering weight in autocross. Lots of turning + relatively low speeds + heavy steering = potential disaster.

Last Saturday, I went to my first autocross since that eternal first number on the odometer changed, since the alignment, and since the depowered steering rack.

Tires

I had on a set of Goodyear Eagle GPS tires, which are made solely for Wal-Mart stores. These tires are cracked and old, and I thought I ought to get some real abuse out of them before reselling them for the rims (a set of 14" NB alloys)I left the Toyos at home because it was supposed to rain that day and I figured I'd be better off with the all-season rubber. Sadly, the track was dry by the time we started our morning runs, so I was an absolutely horrific 4 seconds off pace for my class. I was really astonished at how awful those tires were. I was blowing way past the grip limit on my first run, really sliding all over the place. They're very scary in the rain under normal driving, too, but I was able to keep pace with the guys on Falken Azenis once the track got wet.

Steering

...was surprisingly light. I was even able to palm the wheel! Not bad at all. I can't say I'd be able to do this immediately after removing the power assist though; driving daily with it for 2 weeks certainly helped build up my arm muscles. I will say that after a couple weeks, you don't really notice the lack of power steering anymore, at least not on a light car like a Miata. The next test will be to see how difficult it is with wider, grippier tires and probably heavier wheels.

And that's all I remember; it's been a weeks since the event.

Next weekend, I'll be at the final SCCA Chicago event with my Toyos and grippier brake pads. If I place well enough, I might pull myself up from 6th of 11.

Parking Lot Repairs

A brief bit of catching up: I sold the Mercedes. It was an awful car. It was stately and beautiful, but painfully (painfully!) slow and problematic. Daily commutes tested my patience. Not a day goes by that I'm not glad it's gone.

---------------------------------

The Windy City Miata Club autocross comes highly recommended by Sean, the guy I bought my Miata from. I went to their first event this weekend and brought my friend Mike with.

Lined up for the first run

Mike is riding shotgun.

Coming around the first carousel

And a hard left around the second carousel.

Notice how, even with stiff springs and shocks at the highest settings, she still leans pretty far.

All in all, it was a great time. Running with the WCMC is better than the SCCA in that you get a lot more runs in a day, and they're a little more lax about the rules. You can, for example, have someone ride with you who isn't registered as a driver for the day. They just have to sign the waiver.

The people are really cool too, though as with any group of people, there's a few douchebags here and there.

So, I finished my 5 afternoon runs, handed the car off to Mike, and went out to corner 3 for cone duty. A few cars go by, then Mike goes, far more controlled and stable than he was in the morning runs (and not lost among the cones). This turned out to be his best run of the day.

And his last.

About a minute after he went by, I heard a call on the walkie-talkie: "Alan at corner 3, come to the grid. Alan at corner 3 to the grid." Well shit.

I sprint off the track and across the parking lot. As I approach the grid, I see the hood up and people gathering around my car, and I see a big puddle under it. These words keep repeating in my head:

"Please don't be oil. Please don't be oil. Please don't be oil."

Once I'm close enough, I see that the puddle is bright green. A relief.

The Miata radiator has plastic ends on it. It cracked where the plastic meets the aluminum core, apparently all the way across the top. A few guys help me push it off the grid and into the parking lot. Sean lends me his tools, I call around to area parts shops, and Sean's brother Aaron drives me to a Pep Boys in his NC Miata.

(My picture, cell phone.)

I changed the radiator in the parking lot, collected my prize for winning in my class, and went home. The prize, by the way, is a glass beer stein with the WCMC logo on it. Mike got a ribbon for placing 3rd in class. (No, we're not that awesome at racing; it was the novice class, and the car is pretty fantastic.)

SCCA Autocross, Event 1

I attended the SCCA's Learning Curve in the beginning of April. It was raining, so cold that I couldn't use my race tires, and generally awful weather all-around, but I had a good time and learned a lot about racing.

Last weekend I put on my race rubber and went to the first real SCCA event of the season. I placed 2nd in class.
http://www.scca-chicago.com/solo/2009/event1_index.html
Yes, I'm in 71st, but keep in mind that there were plenty of cars there that weren't street-legal, i.e. open-wheel race cars, plenty of people with a lot more experience than me, and plenty with faster cars. So, I'm happy with my standing.

I'm especially satisfied considering the 1st place in my class (STS) was a well-prepared 91 Honda CRX driven by a man with 30-some years experience in racing. His son, who also drove the CRX, was well behind me.

All things considered, I'm happy with my standings, surprised at my own skill, and I think the sunburn was entirely worth it.

I'm going to see about joining the Tri-State Sports Car Council and the Windy City Miata Club so I can attend more autocross events. This summer is gonna rock.
