Is that the back end of a white Spirit R/T I see there?
That's the one I briefly had in high school, had to sell before graduating due to insurance eventually figured out what it was, then bought back five-plus years later after accidentally running across the then-owner on the old RT Mailing List (RMTL). Unfortunately it was totaled by a drunk driver slamming into it while parked in front of my house not long after that picture, but I still have my red '91 Spirit R/T that I'm the second owner.
Wow, I thought the X-11 was just a decal. Thanks for the edumacation.
Difficult to think of a Citation as a "sport compact" though.
The X-11 did win two years of SCCA Showroom Stock B, the high output V6 was only down 15hp to the base 305 (5.0L) V8 in 1981, they could pull .85g on the skidpad (on early '80s 14" Goodyear Eagle GTs) and it wasn't a lot slower through the quarter-mile than the smog equipment-strangled Corvette.
If you followed some or his amateur racing or are familiar with some of GM's performance cars, especially into the early and late 2000s, the X-11 was one of John Heinricy's
first big projects he was in charge of at GM (his personal site here
). Related to the original poster, the Cobalt SS Turbo happened to be one of his last projects before he retired.
Here's a couple recent articles about the X-11 and why it wasn't just a decal and appearance package:
Im digging that W41 with SS/TC picture.
I need those W41 camshafts and chip!
Thanks. That red one has a reman non-HO 150hp Quad 4 that was put in by a GM tech that previously owned the car. I think he said the owner before him pulled the HO W41 engine for some other project. I commuted in it for a while and think the chassis is close to a quarter-million miles now.
I do have some spares but nothing I'm look to part. All the special stuff is actually on my other '93 SCX W41 that I picked up about 10 years ago. The previous owner built it up with most of the special Olds Quad 4 upgrades from the Rocketparts catalog and chassis parts from one of the World Challenge cars (Torsen diff, baffled fuel tank, etc.).
A couple other decent overviews for those interested in the last of the Olds W-machines:
