The Duetto isn't small? My DD is a BMW 330 Coupe, which is a SMALL (but really fast) car. But when i park it next to my Duetto it looks huge. From the Duetto's drivers seat I have to climb UP to get in the BMW!!

Just had a great race weekend in Spokane. Always have a good time there, and this time, it was even better because I got there early enough on Friday afternoon to attend the police-escorted race car parade from the track to downtown Spokane. We drove twisty/hilly side roads until we got downtown, and then lined up on a closed street in front of a nice hotel to be part of a car show.

It was fun to see the public's reaction to a bunch of race cars showing up like that. Climbing out of the car with people snapping photos, I felt like something between a celebrity and his sports car versus a space alien with its flying saucer.

As for the races themselves, I had a great time as always. Including my customary camping at the track. Lots of improvements were made to the landscaping around the course; removal of embankments, bigger runoff with gravel, etc. People who don't attend this event are missing out. My fellow Alfa racer and friend Tom commented that in the four years he's been racing with me, he doesn't recall me doing any engine work. He's right, and I hope he hasn't jinxed me.

Here I am in the trailer, enjoying a pickle between sessions.

The race season ended uneventfully. I was surprised to learn that I got third place in my class for the season. Surprised because I was always midpack in the >2L medium bore group where I was assigned to race, and didn't realize I was still being scored for the <2L class. I was also surprised to see a small picture of me racing in our club's magazine.

There I was, running by myself, midpack in the medium bore group, exiting turn 9 to enter the straightaway at Pacific Raceway during one of the Fall Finale races. It was raining off and on that weekend, hence the dark clouds and sunlight. I think there was a rainbow at some point. Anyway, I liked the picture so much, I tracked down the photographer and bought the image. Here it is, taken by Bert McBride.

Nader, is that car Christian Sniady`s or Jon Norman by chance?
Car belongs to McKean. Pretty sure the engine is built by Jon Norman's shop. Fred S. (JustcallmeFred) maintains it, he knows for sure.

Happy holidays.

Thinking about it, I've had two relatively minor recurring issues with the car.

One is the side dump exhaust with the megaphone cracking and falling off. I fixed that with beefier welds and better rubber mounting.

The other is failing alternators. I think I've mentioned it before. In one of my last races, the nut came off the alternator mounting bolt, and I lost the 10/12mm shouldered bolt. Must have been because of all the mounting and dismounting of failed alternators, and I probably under-torqued it last time. Anyway, by mid race, the alternator was hanging on by the tensioner. No alternator means no water pump. Discovered it when my radiator boiled over in a race and my temp needle got pegged. Luckily caught it before lasting damage was done. Luckily, @justcallmefred had a spare to loan me, and I was able to finish the weekend. Thanks again, Fred!

That bolt is a little tricky. It's 12mm through the engine bracket, then narrows down to 10mm for the alernator. And because of my setup with the mini alternator and oversized (underdrive) pulley, it can't be too long or it will grind against the pulley. I had to make one to replace the one I lost. If I'm going through the trouble to make a bolt, especially a big one, then by now you can guess how I'm going to it. Grade 5 titanium. If I'm making one, I might as well have two. Finally got around to doing it. Here's the process once again, starting with a couple of very nice longer-than-needed bolts, that needed to be shortened, then turned down and threaded on a lathe. Then finished by hand:

Finished product beside the other bolt that still needs cutting+threading. Also showing the piece of 10mm allthread I used to limp the car on and off the trailer after giving Fred back his bolt. Realistically could have used this hack indefinitely. Oh, and here's a small example of Ti wool I'm collecting. I now have multiple grocery bags full of this stuff. Just can't bring myself to throw it out. And finally an uninteresting picture of the bolt in its oily home. Engine bay is always this ugly by the end of the race season. I'll clean it next Spring.

Maybe you should lock wire the bolt in so you never have this issue again. Just a thought ... and nice work :)

Thanks, Pete. That's a good thought. My race bikes are extensively wire locked. But with cars, especially this situation, space is awfully tight for wire locking down there, especially from above. I always use anti-seize on all the titanium and stainless fasteners on my projects, but in this case, I'll probably just use blue thread-locker in addition to a locknut. Belt and suspenders setup. And since I know you're thinking it, there's not enough space under the nut end for a lock washer. And putting one under that beautifully flanged titanium bolt head would be barbaric.

Since I mentioned bikes, they'd get jealous if their pictures weren't included. Here's a front hub, locked down in wire. That's a titanium brake stay I made, go figure. And yes, there's a Gulf Blue race bike lurking in the background.

The stand-off brackets were for an earlier (crude) alternator installation but, as an alternative to safety wire, I still reverse the big bolt and double-nut it.

Maybe you should lock wire the bolt in so you never have this issue again. Just a thought ... and nice work :)

Another simple option is to drill the bolt for a split pin to trap the nut. Yes it might work loose but it cannot come off, meaning the bolt will always be there and races finished and won.

Thanks, Mac! I appreciate that. I, too, use other people's projects as inspiration for me to forge ahead with my own. I'm glad mine was able to do that for you.
