Speeddoctor-Quiz- on Nissan Knowledge

[themadscientist]

wo ho Frazier vs. Ali.... I dan't want to get hit by a stray punch....you both know more than me on this one...we have a member with a Paul Newman edition???? shiiiooot-fire!!!! pics anywhere?

Ask and ye shall receive Doc. It's part of my pair of R30s.HR30 L20ET



DR30 FJ20ET



As the resident R30 guy, let me show you fellas the obscure models.

R30 hatchback. L20 powered, not very attractive IMO.

R30 station wagon, RHR30. They came Z18 powered but this guy has created an RS with an FJ20 swap. headlights and grill, plus correct paint and graphics. This car is dead sexy.

[Speeddoctor]

Thema: Thx for coming by the neighborhood with those educational/envy provoking pictures...I love the wheels, flares all the old school JDM.....looks like these cars reside over-seas.

Speedocson will like these a lot...he loves the FJ20!

Thanks!

[themadscientist]

Yeah, I live in Japan right now.

[raremotive]

Speaking of FJ20, hows yours coming?

[hannibal]

Whew... almost missed quiz 8...

1) False. MoD nailed the reasoning on this one

2) True.

3) False. I know bigger diameter exhaust usually reduces low end torque while increase high rpm power. I see a cat as a similar restriction.

[themadscientist]

Speaking of FJ20, hows yours coming?

I'm broke.... The rest kind of writes itself.

[raremotive]

it appears you have enough to have ambitions for a CA18 and a set of new pistons.

[themadscientist]

Bought those before I sold my soul to get this new house. love the crib, hate the drain on my money, but it's an investment.

[raremotive]

Yeah, other things come up that stop us from achieving our crazy dreams.

[Speeddoctor]

Great job to all!!!!I love to see the dialogue this thread occasionally generates....Answers to Quiz #8:1. False. The N.A.C.A. duct was designed by folks at the National Advisory Committee for Aeronautics...Nasa's predessessor in 1945. AKA the "submerged inlet". Unlike raised intakes, it has less "form drag" and "flow seperation" and as a result, allowed a better inlet flow/coeffecient of drag ratio, thus being superior to the raised inlet. Two early jets used them for jet intakes: the N.A. YF-93 and the Short Sherpa.

2. True: Nissan Skylines came in 4-door and wagon versions. They weren't RB26DETT GTR vspecs; most Skylines weren't. They were 2 wheel drive cars with milder Nissan powerplants.

3. False: Cats == backpressure even the performance cats, and thus increase torque at the expense of high h.p..

Awesome job guys!!!!!

NICO/Speeddoctor Quiz #9:

This is a non-Nissan Quiz....the last one seemed popular, so lets do it again!

1. True or false: The swing-axle design usually led to understeer.

2. Who penned the design of cars such as the Studebacker Champion and Hawke? a. Steve Avanti b. Bill Mitchell c. Raymond Loewy d. Ed Crossle

3. Where does the name "Isky" cams originate from?

Good Luck! S.D.

[Ace2cool]

1. Swing axle makes cars handle unpredictably, due to the flux in camber when the road is rough.

2. I'm gonna go with Steve Avanti, because he's the first name on the list. I don't know about the Studebaker era...

3. I'm gonna guess the designer/creator person. (this is where the attendance vote comes in, cause I have no clue on the majority of these)

NICO/Speeddoctor Quiz #9:1. True or false: The swing-axle design usually led to understeer.2. Who penned the design of cars such as the Studebacker Champion and Hawke? a. Steve Avanti b. Bill Mitchell c. Raymond Loewy d. Ed Crossle3. Where does the name "Isky" cams originate from?Good Luck! S.D.

I did bad on the last quiz, but I am not giving into the temptation to google...

1. True...usually 2. a. Avanti (never guess a. ) but I like Avanti design.3. Len Isky (never guess Russian)

[hannibal]

Tough questions this round!

1) False. I'm gonna say a swing axle would lead to oversteer. I'm basing this on the VW Bug, the only car I know of with a swing axle suspension.

2) a. Avanti. Thats the only name I know on the list and I believe there was a Studebaker model named after him.

3) ISky?!? Apple started building cams??

[Speeddoctor]

Ok... almost spewed my coffee on the keyboard....u guys are awesome!!! these are hard.... u guys crack me up...ur personalities are coming through....ace, ur right bro...attendance baby....some good answers...

Hey....this stuff u should and will know and it aint rocket science!!!

4-door GTR? I think its prolly a R32 GTS-T 4-door but Im under good word that it is in fact a 4 door GTR.

The first ever Skyline GTR was a four door car...

removing cats kill your low end torque

[themadscientist]

removing cats do that on NA cars. Your turbo's exhaust housing does that on boosted cars.

Autech built a four door RB26DE R. That car in that pic isn't it.http://www.movie3mai.net/dqCntXmvM4m0.html

I think I have seen all three of the cars in the background of that picture too. That's Okinawa ain't it?

^know where I can get a used intake plenum for a rb26?

*page needs to be bumped*

[Speeddoctor]

Man......its getting hot in here!!!!!!! The bulleye is getting nearer and nearer....Can't wait to give ya'll the answers.....

[Speeddoctor]

chuga chuga clunk.........is Quiz #9 dead?.....do we have pre-maturequizalation?

[Speeddoctor]

Thoughts on quiz #9:FYI: I do these questions from the top-of-my-head so to speak.....so, I know them without looking them up....but, occassionally, I'll deepen my knowledge after asking the question; for the sake of the quiz-takers. There are certain topics I strongly encourage you all to look up as there is so much more info; than I can go into here. An example is the Raymond Loewy story....

I have always loved cars and motorcycles...since forever....they have been my friends...of sorts...as I get older, I realize that each of these cars are the results of hundreds of people's dreams, ideas, hard work and lives...many of whom, when it comes to classic cars, are long-ago deceased and these cars are an emodiment of all that remains of them....Thus, another reason to know and to preserve and to cherish...

see next thread for the answers to Quiz #9:

[Speeddoctor]

Answers to Quiz #9:

1. FALSE: Swing axles have always been linked to oversteer: (rear- slides out unexpectedly)..examples include, the Triumph Spitfire, the Porche 911 and 914 and the original bug.....countless fatal accidents have made it a tragic part of history. The reason is that when you make the mistake of hitting the brakes in a corner..(which u should rarely do anyways) the weight; (like in all cases) transfers to the front. With swing axles, this results in a quick, unloading of the rear suspension; resulting in extreme and rapid positive camber, a greatly reduced contact-patch and look out...the resulting number of spins could be more than an Olypic snow-boarder!!!

2. RAYMOND LOEWY: French born, he was one of the best known industrial designers of the 20th century. As an American designer, his influence on American culture was broad.Outside of the Studebaker's and yes, he penned the Avanti, he designed:1. The very sleak S-1 locamotive seen in pics all over... very art deco..2. 1939-1954 Farmall Tractors3. Schick electric razor4. Harley Knucklehead parts5. 1950 re-design of the Coke bottle6. Greyhound Vista cruiser7. Hillman Minx8. Exxon logo9. Shell Logo10. The Concorde interior for Air France11. Interior design of the Space Lab12. Frigidaire fridges13. Zippo lighterWow! His car designs were always ahead of their time...and sometimes viewed at the time or retrospectively as quirky...(he was after all French-born)....But, he had many victories....the 53 Studebaker Commander Starlight has been recognized years later as one of the most beautiful cars ever made and the Avanti's styling was so advanced that it's body style goes from 61-present...

3. Ed Iskenderian: So. cal. icon....original cam shop still stands in Torrence Ca. Was in the fore-front of the Hot Rod, Drag and Bonneville scene.

Great job guys! S.D.

Nico/Speeddoctor Quiz # 10:

You guys are doing great!

1. Direct overhead cam designs are better because: a. less moving parts b. speeddoctor says so c. less valve-float at high RPMs d. all of the above

2. High speed aerodynamic drag increases with increase in speed by a factor of a. X x 2 b. X to the fourth power c. x to the second power d. non of the above

3. When Mr. K. took his first L.A freeway test drive in a Bluebird sedan, what was he most concerned about after his aborted trip?

Good Luck!

[seang]

1. a. The added weight of pushrods and/or rocker arms means that the valve spring will not only have to close the valve, but reciprocate all the other parts. This leads to answer C, which, on a direct acting OHC setup with less moving parts loading the valve spring, it seems that the valve would have less tendancy to float at a given RPM compared to other designs. Pushrod actuation does afford a compact and simple powerplant, though.

2. I'm guessing C.

3. Another guess, the fact that his car was called a "bluebird" and not something more edgy.

1. gotta go with D."all of the above".2. I think it's c. or squared.3. getting robbed?

[Gold Digger]

4-door GTR? I think its prolly a R32 GTS-T 4-door but Im under good word that it is in fact a 4 door GTR.

The first ever Skyline GTR was a four door car...

The only factory produced RB26DETT powered 4 door GT-R was the 40th anniversary R33 GT-R.

It was a joint effort between Nissan and Autech. There was also an Autech/Nismo version if the stories I have heard are true.

[Speeddoctor]

Ahh...I see Quiz #10 is another opportunity for growth and humor!!!! LA Freeway..good one...

GOLD: Let it go bro...its all good...we aren't on quiz #8 anymo...we on #10....
