Paul,
Have you ever driven or seen (in the metal) a three rotor Mazda
Cosmo Eunos?
Best,
Bruce Smith
Yes in Japan and in Sydney. They also made a 3 rotor 4 door sedan.
Never drove one.
Paul Lamar
Eunos 800 is the same thing as Mazda Millenia it was never rotary
powered. Its FAIL wheel drive. But did have a supercharged Miller cycle
engine for a short time.
-Dan Gorsline
I did not look under the hood but I was told it was a 3 rotor. It seemed
a lot larger than a Millenia.
I have a friend that owns one. My translator may have made a mistake.
The Japanese were very happy to meet me as they were Chaparral fans and
i signed a few pictures with me in them back in those days :-)
Here is a translation of the Japanese magazine article attached.

Machine and racing for Trans-AM race
Kanji Satoh
How to quicken the pit work a sequel to the previous issue
I have already mentioned about 1) fuel supply tank, 2) water and
oil supply, 3) provision of the impact wrench. This time I will talk
about
4) wheels and tires. It depends on the weather but just in case
get a set for the rainy weather and two sets for the sunny weather. The
wheels can last for one season unless you don't do a rough off course
maneuver-. Be careful no damage to the wheel stud (wheel nut).
5) Get a fireproof and heatproof suit and gloves ready to exchange
rear end while racing.
6) Most of the tools are Snap-on tools or Craftsman tools.
Other Points
I've talked about most of the things of building the car and now
let me mention what you might care about most.
1) 99 % of the bolts, except the special bolts, are G-8 fine thread
(grade 8) bolts and nuts and they should be fixed with safety wires.
2) The price of car itself was about $3,500 but the whole machine cost
$19,00 However, GM Pontiac Division will pay about $10,000 dollars so,
you can buy it for about $9,000 dollars which is very cheap.
3) The fuel tank will not leak even if the car overturns.
4) When the car is finished, we weigh it by each wheel. In our case, it
weighs about 1,262 kg and to get the balance correct. we bolted 59 kg of
lead ballast in the rear trunk area .
As you see the from the figure on the next page, if you shave off
the port carefully leaving only the valve seat the flow of exhaust gas
causes a diffuser effect and more exhaust gas will be passed. When a 2
inch-valve is used, for example, it looks like as if you I've made it
into 2 and a half inch size.
T/G Racing Company in Talzum??City, California. The car: is a
1968 type Pontiac Firebird. Car No. 27, 37. Bosses: are Jerry Titus,
40 year-old, and Terry Godsall, 30 year-old.
Terry Godsall: He is a successful businessman involved in various
enterprises and is called a Howard Hughes in Canada. He backs up the
biggest Pontiac dealer in Canada, has a civil engineering & machine
company and so on, and appreciates the races very much.
He drives two Rolls Royces; a black one for business, and uses the
silver one for leisure activities. He also has three airplanes. One of
them is a ten- seater Lear jet, which cost a million dollars and the
others are twin-engine light planes.
Jerry Titus: Being experienced, tough and tenacious, he started
his career at F-J (Formula Jr.) in 1960. While working as a chief
editor of a sport car graphic magazine for seven years, he had won three
SCCA national championships in different classes in two years. After
these achievements were accomplished, he joined a Mustang Team in 1966,
being welcomed by Carol Shelby in 1967. He finally became a Trans-Am
champion driver. He got four first prizes, three third prizes, a
fourth and a fifth. At Daytona 24 hours, he was in the fourth in 1967
and in the first both in 1968 and 1969. He also made a track record
race record and lap time at each race place. He drives four wheel
drifting slides which is a dirt track style as he passes through the
corners on the asphalt course. He drives faster than any other
drivers. He drives like that famous Parnelli Jones. He says if you
cannot make your best lap time in the first 5-8 laps on any type of
tracks, you are not professional.
His mechanic team is comprised of:
Julli Schwarts
Chief mechanic. He used to be a chief mechanic of Shelby American
Racing Team. He was chosen the Trans-Am Mechanic of the Year in 1967.
He is quite an excellent fabricator. He is also an expert of engine
rebuilding and pit work during racing as well as showing a great skill
in bodywork including sheet work and painting. He has worked for Ford
TOYOTA 2000GT etc. which were driven by the late Ken
Miles, Walter Hansgen, and Ronnie Bucknum while winning at Le Mans. He
is so much experienced and so sharp.

Julli is testing steering. He could have used the driverside
but he wants to do this away from the mass media because it is not
finished yet.

The front covering assembly, which is detachable and has been just
taken off. This makes the race activity go quite smoothly.

Doan Spencer
He is a chief mechanic for G7 class and a mechanic for an
influential member of the Hollywood Sportscar Club. After retiring from
the Navy flying corps, he worked for private aviation as a chief
mechanic for DC-6B He told me that in those days he flew this plane 17
hours a day and that it took him 15 minutes to exchange the engines per
plane. The MG which won the Le Mans has also a lot of interesting ideas
of his own. Like all wheel disc brake, non-slip differential or
limited slip differential or posi~traction in America, and an idea that
made these differentials leak proof even if the rear shaft breaks. He
is said to have tried an O ring which is often used for the bike
engines, and used it for practical use for the head gasket of the Ford
racing engines. This works very well, they say. He has been successful
in this practice for 5 or 6 years though it costs a lot. It was he who
maintained no.17 car at the 1968 Fuji 200 Miles. His chassis setting
was almost perfect.
John Philips
He is a mechanic.. He is an expert knowing everything about the
compatibility of all car parts, which is called reference.
Dusty Roads [ Now owns an FBO at Whiteman airport in So Cal]
He was a champion of Drag Race and has an official record of the
1/4 mile in 6.87 sec. in his handmade hotrod. The final speed appeared
to be 220 miles (352 km/h). As having experienced in hot rod races,
both on land and water, he knows the limits of the materials to in which
to build a car.
George McCullough
An ex boss of the welding section in production of the Saturn
Rocket, Apollo Project in NASA. He enjoys amateur races and is a good
joker. He taught me various welding techniques.
Gary Hall
He is from Canada and a Rally Champion in Canada. He won a prize
competing Nissan Factory at Shell 4000 km. Very sharp and young.
Larry Burg A Canadian mechanic once in Shelby American. His job is
very precise. He is a tough guy, working for 40-50 hours without a rest
and still maintaining good cheer.. A very good guy.
Kanji Satoh
A 180 cm tall man from the Far East. Having belonged to PMCS, he
is now a mechanic and car maker being scouted while learning to be a
racing engineer. His motto is perfect finishing.
Paul Lamar
He is an expert in aerodynamics and has his own company named Lamar
Engineering. He designed and made a spoiler which is attached to
Chaparral car made by Jim Hall, which is famous in a group of 7.
The effect of Spoilers
One morning in my workplace, a month after I arrived in Los
Angeles, the boss asked me if I would like to go to Las Vegas. When I
said of course without any hesitation he told me to go to the Stardust
Racing place for aerodynamics tests. So three of us went to Vegas on a
one week business trip. We took Route 66 to Barstow, then Route 15
to Las Vegas. We reached there that night and stayed at the Stardust
Hotel. The result of the test is shown on the graph on page 176. We
took the average of both tries to the south and to the north.
In the next issue, I will tell you about the first Michigan race,
the second at Lime Rock, and the third at Mid Ohio.

taken when I went to stardust race place to test aerodynamics. It
took about 1 week.
