Acronyms, Abbreviations, Technical Terms & Jargon

[GaryDG]

More acronyms:


FD = Fuel Distributor
AFR = Air to Fuel Ratio
FV = Frequency Valve
AFM = Air Flow Meter
CD Box = Capacity Discharge Box

What about ISV & ECU

tngirl74 - if it wasn't for physics and law enforcement, I'd be unstoppable.
'88 911 Carrera Cabriolet

In my early work environment, I learned a variation of this one, called "The 7 P's".

"Proper Prior Planning Prevents Piss Poor Performance...."

Never forgot that one.

Here are a few serious websites that may help with this project:

and one funny one:

* notice that no one has come up with a put-down acronym for Porsche yet!

ICV = Idle Control Valve

This is great Randy!
I've learned alot just by what's here now.

glad it's useful

SWB was posted above, but LWB was not...

LWB = Long WheelBase, technically it could refer to any 911 during or after 1969, but in practice it is usually restricted to mean those from 1969 to 1973 (i.e. the LWB early cars with long hoods).

Excellent thread. Rwebb posted SAE.... Society of Automotive Engineers

What is DIN? (pertaining to horsepower.. for that matter what about BHP?) anyone pls jump in w/short explanation of methods used for SAE vs. DIN horsepower ratings; for instance, early 911E listed @ 158HP DIN but @ only 140HP SAE.. (I might have those reversed)..thks

[RWebb]

DIN = Deutsche Industrie Normal (did I spell that right)

Who remembers the years and specific auxillary devices involved in the hp changes?

SAE hp - used to allow the manf. to disconnect all (?) or most power robbing accessories (alternator, power steering pump, etc.) and ws much higher than DIN hp.

In the year _____, SAE switched to a measurement protocol that required some or all acc. to be connected, and was about equal to DIN. They called that SAE Net hp, and went back and called the old way SAE gross hp. So the same hp might be labelled SAE in something written in 1961 (a guess), but called SAE gross hp in something written in 1988.

There may be other stuff, but is all I recall at the moment. I bet Google would pop up the "rest of the story."

What's WOT? Is that an acronym?

[oceanvue]

Oh and in case you come across any 928ers and you hear them refer to an OB that means "old bastard" refering to the early 16 valve cars.

[RWebb]

WOT = Wide Open Throttle, aka Wheeee!

[DARISC]

Has BTDC been mentioned (degrees Before Top Dead Center)?

[porsche4life]

Sadly i havent seen PPOT= Pelican Parts off Topic.

Maybe because it's OT?

Great thread idea !

I may have over looked it, but in the very first post you called the early cars "Long Nose". I've always heard "Long Hood".

Could you also add the different "states" of an engine, such as what components are actually included in a "long block" that's for sale v/s a "short block" or the other alternatives ???

The very simple answer is in Wayne's book: How to Rebuild and Modify Porsche 911 Engines 1966-1989 on page 198, "The value of SAE and DIN horsepower are very similar with 1 SAE HP being equal to .98629 DIN HP."

In general, horsepower is a measurement of the engine's ability to perform work. SAE is measured in pounds and DIN in kilograms. One SAE horse is the ability to lift 33,000 lbs one foot in one minute. One DIN horse is the ability to lift 450,000 kg one cm in one minute. Thus, for the same power the SAE measurement is 98.629% of the metric DIN measurement. As Wayne points out, not much difference!

There are now various SAE measurements such as "Brake horsepower" (BHP), "Certified Horsepower," "Gross Horsepower" which all measure the HP in different ways by taking into account the loss caused by various mechanical components (gearbox, engine accessories, emissions controls, exhaust system etc). These specific SAE measurements would modify the above answer with different mathematical calculations so consider the above answer a "general rule." For a more thorough answer, check out: Wikipedia - Horsepower.

thx - i'll delete my post to clean up the thread...

Short Block vs. Long Block

Short-block vs. Long-block question

[RWebb]

NVH = Noise, Vibration, and Harshness -- bad things that designers attempt to eliminate from suspension systems, motors, etc. -- even in sports cars

----well, don't I look like the guy that doesn't know how to use the search bar.
(maybe it'll still make it in the Wiki though..)


Thanks !
