Sorry if this sounds really stupid...but what does the S designation for my 1975 stand for? I have read Bruce Anderson's book and I am still not clear on the main changes in the model from the 911 and 911 carerra. <img src="graemlins/a_smil17.gif" border="0" alt="[blabla]" />
Just wondering.

It is the first letter of what you say the first time the tach needle sweeps past 6

"Holy ****"

I remember reading somewhere "T" was for touring and "S" was for sport.

...and furthermore, SC stands for "Sport Coupe".

 

I remember it standing for sport up until the SC model mentioned by Jeff. There was a T= touring, E= economy, S= sport and a few years of an L= luxury which was an S with some added interior comfort items, if I recall correctly. Somebody please correct me if I am wrong.

 

Well according to the "Porsche 911 Red Book" by Paternie, the "S" debuted in 1967 as a "Super" model. 1968 saw "L" for "Lux", "T" for "Touring".

In 1974 "The T and E model designations were dropped from the model line. The base model was now simply called 911 while the S became more comparable to the E of previous years. The Carrera went from being a limited production special to assume the previous S role as the top of the line performance model."

"In 1975 the base model 911 was eliminated from the US model lineup. For the American customers, Porsche divided production of the 911S and Carrera into 49-state and California versions based on emissions controls. The 49-state cars were fitted with an air-pump whereas the California cars were also fitted with thermal reactors and exhaust gas recirculation (EGR) systems."

Hope that helps !!

 

I thought SC stood for Super Carrera?

 

back in the 356 days, S stood for "Super" & referred to the engine being upgraded (ie 1600N (Normal) vs. 1600S). the "S90" was a Super tuned to 90HP (heck, you can get +90HP from a chip, bypass & machined throttle body these days, can't you?)

 

If SC stands for Sport Coupe, what about the SC Targa?

I once asked Bruce Anderson what SC stood for. His reply: Super Carrera <img src="graemlins/wave.gif" border="0" alt="[byebye]" />

Thanks...super!

What is the difference between the the 911 and 911S? Is it just the Koni shocks and some engine mods? <img src="confused.gif" border="0">

H.D. Smith,
For 1974:
911=150 HP
911S=175 HP
Tires (stock)
911= 5.5inch x 15, 165 HR15
911S= 6 inch x 15, 185/70VR15

Gearbox
911= 915/06
911S= 915/40

 

thanks...that is what I was looking for.

Now another question

What is the 915/40 tranny? Is it just a different gear ratio?

Same gear ratios. I suspect it was just a stronger tranny due to the higher hp.
