I totally understand! Thereís a reason Iím building a Datsun Roadster and not a 2002, GTV, 510 or anything else to run in that B-Sedan group . Itís not just the displacement youíre battling but the guys with deep enough pockets to squeeze all the power out of the motors that only need to last a seasonsí worth of hours. Those guys are usually in B-Sedan. Iíll happily battle the Alfa Spiders and the assortment of British cars.

That particular gent has made some wise choices in his life as he campaigns a pair of 2002s, a CSL, a Chevron and I believe just picked up a E30 M3 too... sigh...

Hey Nader!

Finally finished the thread. Slow days at work for the last few days has really helped. As expected, the thread was wonderful; it made me laugh, made my cry, made me proud... all the emotions! haha

If I can make one suggestion for a "someday" project, blocking off the openings that was done in this post (I dont think the pics came with the quote) left a nice opening on the insides for the radiator, but it leaves air a path to escape from and not head towards the radiator... path of least resistance ya know?... So my suggestion is to add some additional ducting/ shielding so that these openings direct all the air into and through the radiator. Probably want to add some mesh too just to prevent directing things other than air into the alooomineum radiator. Gotta protect the goods right?

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.

PSk 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.

conedriver 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.

Nader 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.

Nader 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.

Nader 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:

Car belongs to McKean. Pretty sure the engine is built by Jon Norman's shop. Fred S. (JustcallmeFred) maintains it, he knows for sure.
