-
- As of July 1, 1992 there were 123 million automobiles registered in
- the USA. According to my 1936 Dyke's Automotive Encyclopedia, there
- were 26.5 million registered in 1936. Not bad for the Depression.
-
- ================
-
- Most chassis designers don't worry about Ackerman angles any more.
- With today's wide tires, Ackerman plain doesn't work. That's why I
- was astonished to see a photo of the front end of Jim Yates' 500 CID
- Pontiac Pro Stocker. It has massive amounts of, not Ackerman, but
- anti-Ackerman, which is sometimes used on autocrossers and lower-
- speed open wheel cars, but seems awfully out of place on a drag-only
- ride.
- ================
-
- The California Highway Patrol has some new Crown Victorias. They're
- a little faster than the average Vicky, thanks to Paxton superchargers.
- One hopes they've received official blessings from the C.A.R.B.
-
- ================
-
- Lucas' new ABS system is supposed to be lighter, smaller, and cheaper
- than contemporary units, and will incorporate a "gee, why didn't *I*
- think of that?" feature - a built-in hill-older for manual transmission
- cars. It's about time!
-
- ================
-
- Chrysler claims they'll be adding passenger-side airbags to all their
- new models within the next two years. Don't blame me if the things
- blow your eardrums out when they go off - airbags are downright
- dangerous, despite what insurance company and NHTSA propaganda says.
-
- Nissan is at least aware of the problem - if you order their rear seat
- airbag, the passenger/front bag is deleted so the compression doesn't
- blow your brains out like squeezing a zit.
-
- ================
-
- Jolly good: After relying on other peoples' engines for thirty years
- (though their 3.8 Turbo variant of the ancient Buick 215 was HOT),
- they now have their own engine - a 4.0 liter V8 with a 75 degree
- cylinder bank angle, 180 degree crank, SOHC with two valves per
- cylinder, and it's designed to work as a stressed chassis member.
- They claim 363hp @ 7000, 348 ft-lb @ 4500 for the standard motor,
- with 505hp @ 8000 with the hipo model. Frankly, even considering
- the ratings are almost certainly for non-US-emissions motors, I
- think they're lying through their teeth. 348 ft-lb out of a two
- valve, 240 inch street motor is right out at the outer limits, and
- that'd be one wildly cammed mofo. With the weird 75 degree vee *and*
- a flat crank, it oughta shake more than yer average paint mixer too.
-
- ================
-
- BMW was widely criticized for their drive-by-wire throttle control.
- The pedal on the floor connected only to a position sensor, which
- then actuated the throttle body as it saw fit. Now Detroit is
- jumping on the bandwagon, but they're carefully avoiding the term
- "drive-by-wire." In New Acronymese, it's "ETC", or Electronic
- Throttle Control. Pretty soon you'll be able to just sit in your
- swivel chair and drive your car around with your computer.
-
- ================
-
- Talk about Slick 50 has probably consumed more usenet bandwidth than
- Craig Shergold's business cards. Now to throw some gas on the fire,
- Allied Signal, maker of Fram filters, has reputedly done a study of
- Teflon oil additives, and claim they're passed right through Fram
- filters and remain in the oil.
-
- ================
-
- The '93 Corvette's run-flat tire option is foreign made. The '95s
- will have special Goodyear Eagle run-flats as standard equipment.
- This will eliminate the spare and jack, but nobody in their right mind
- ever crawled under a Corvette to get the f***ing tire out of its
- pickup-truck style mount if a wrecker or AAA was handy anyway.
-
- In other Corvette news, the '92 LT-1's magnesium valve covers have
- quietly become plastic. Talk tech all you want, but plastic is
- still plastic to me.
-
- ================
-
- Supidity compounds: GM is reputedly studying the possibility of
- building a V-10 engine for their full-size pickups and the Corvette.
- You've heard my opinions on the V-10 layout before. The silliest
- part is, GM's 454 just went through major redesign to become the
- Mark V and is in current, smog-legal production. They're selling
- the 501 as a crate motor, but certifying it would be trivial. There's
- no *reason* to make a V-10. If they wanted more cylinders, the
- obvious choice would be to add four to the 350, like Ryan Falconer's
- Chevy-based V12. Yep, Falconer casts his own blocks and heads; the
- engines are frequently used in drag boats.
-
- ================
-
- The new Camaro looks like it just blew the Mustang completely out
- of the water. Sure, it's double coyote ugly, but the detuned LT-1
- 350 and Warner six speed should give it The Power. McPherson struts
- are gone (yay!) replaced by conventional A-arms (yay!). Oh, and
- for name droppers, the project managers of the new Camaro project
- were Dave Hansen and Jim Westby. The cars will be built in Canada.
- ABS is standard, and GM claims 160mph top speed for the LT-1.
- Unfortunately, dual air bags are standard.
-
- ================
-
- Oldsmobile wanted Cadillac's Northstar V8 *bad*, and they got it.
- It's downsized to 4 liters and 250 bhp, and most of the major parts -
- like the heads, rods, crank, and pistons - are unique to the Olds.
- It evidently won't bear the traditional "Rocket V8" tag due to some
- weird internal GM politics.
-
- ================
-
- Ever wonder what happened to steel shim head gaskets? One problem,
- which they have in common with solid copper gaskets, is fretting.
- That's why major racing teams have mostly gone back to cardboard
- (excuse me - high tech composite) with steel O-rings. The fretting
- problem is aggravated with engines using iron blocks and aluminum
- heads, so AE Clevite has introduced a new graphite-coated head
- gasket.
- ================
-
- Cadillac's little-loved Allante is scheduled to bite the big one at
- the end of the '93 production run. Of course, if previous sales are
- any clue, new '93s will probably rot in the showrooms until the turn
- of the millennium.
- ================
-
- Are you lazy? *Really* lazy? GM's adding a power operated side door
- to the '93 Lumina van and its variants. Of course, it has so many
- safety features it's a pain in the ass to use, but no pain, no gain,
- right?
