Forgotten History
I was at Sebring Raceway this weekend for the Trans Am series races. They allow you to walk pit lane before the main events. I looked up and there it was, a part of Oldsmobile history.

I've always considered it a lost opportunity that Olds spent heavily in NHRA, IRL, and sports car racing in the 1980s and 90s and didn't publicize it, at least not outside of enthusiast magazines whose readers already knew about it. Talk about a lost opportunity. Then they pulled the funding because they weren't getting sales results. DUH!

The 80's was when Roger Smith, a "bean counter" was CEO of GM. He believed "quality" beyond meeting minimum expectations was a waste of money. First Oldsmobile was neutered and killed off, then it was Pontiac, who introduced the Solstice.
GM kept Buford because a deceased Chinese dictator liked them ? The idea that they had a slightly higher profit margin on Buford's sounded good, except the volume was way less than Olds or Pontiac. Buford was well known for what ?

Cool they have that at Sebring. Here's a shot of McKee MK.7 4WD Can Am car powered by an aluminum 455 twin turbo and a modified Jetaway transmission with four speeds and the pitch fixed in either high or low. Granted I don't fully understand the pitch thing. They did power a number of Can Am cars including a McLaren. As previously stated it would have been nice to see them more involved in racing. I'm sure GM had the reins on.

Do not get me wrong, I wish Oldsmobiles (and Pontiacs) were still in production, but Buick sales are successful in China.

Wow, yea that is a lot of engine. I guess it would have been hanging out of that MK.7. I used to go to the historic races at Elkhart in the early 90's and saw a couple Olds powered Can Am cars but wasn't sure what they were since my knowledge is limited. Thanks for the pictures.

I like that angle drive distributor on the yellow car.
Regardless of which divisions got the axe, even if the Olds marque was still here, would we recognize it? So many things had gone corporate. GM's cars are now Medium Expensive, Expensive, and Very Expensive for their three car brands (as are everyone else's.) The model seems to be Normal Marque, and Luxury Marque. Ford, Chrysler, Toyota, Honda, and Nissan seem to be following that, with the first three axing a division a decade or so ago. GM always had the most divisions and still does. While Buick isn't strictly necessary, I wonder what the difference is between Buicks and just expensive trim Chevrolets. From my experience, I can tell you what the difference is between a Toyota and a Lexus. One more coat of paint, and nicer interior and radio. Same sheet metal, chassis, and powertrains.

I'm curious if any of you with the Hot Rod article know what brand those turbos were? They definitely have a period look to them but it's interesting to note they're both mounted for clockwise rotation. That tells me they're off-the-shelf units and not specially developed parts for that engine. Also given their size, I'd say they came from a commercial vehicle (truck/tractor) application rather than pass-car (keeping in mind the number of pass-car turbo applications in 1969 were very limited and almost exclusive to Europe). This might surprise some of you but I can assure you, it's VERY common. You'd be shocked at how many 'race' turbos are actually units off of your every day John Deere tractor! Pretty cool integration of some old school wastegates, too.

“1958: TRW (Thompson-Ramo-Woolridge of Cleveland, OH) develops the 300 Series Turbocharger
1969: RAJAY Industries (Long Beach, CA), a unit of the Texstar Corp in Grand Prairie, TX, acquires the entire TRW turbocharger line. Texstar later became a unit of the Hillman Co. of Pittsburgh, PA.”

In case anyone in interested, here is an article on a 300 series Rajay turbo from 1997 which looks to be very close to the TRW units used on that aluminum 455. As noted above, TRW sold their catalog to Rajay in 1969 and, more interestingly, the design was ultimately bought out by Garrett in the mid '80's. Garrett has been a key OE turbo manufacturer since the '50's. They supplied GM with the turbos on the early '60's Jetfire and in the '80's for all of the various turbo Buick's - T-Type, GN, GNX.. Yes, they are still an OE supplier today.
It looks like the '300' nomenclature stems from a 3 inch "rotating group" which is a bit unique. It's not unheard of to have a 1:! ratio turbine/compressor but it certainly isn't common (compressors are typically larger than the driving turbine by as much as 1.5x or more). That size range puts in the neighborhood of what might typically be used on a 6-ish liter inline 6 diesel engine today.

Just came back from another day at Sebring.
They have a building there for driver meetings etc, and this year they had a display of about 20 cars. Low and behold look what showed up.
I used to live not far from Wayne Taylor when I lived in North Orlando. Ran into him a couple of times here and there. Nice guy.

I worked for the Menard IRL team in the mid-late 90's for the Indy 500. Ran the Aurora engine in those cars. Much more reliable than the Menard V6 turbo from a few years prior (based on the old Buick V6.
