I've put together a list of buzz words we use in our threads. I hope this will help the new people understand better and make informed decisions about what they need/want for their Poney. This is by no means complete or possibly correct so, if I'm wrong, it would be a great help if you experienced folks would chime in and help make it right. I certainly would not take any offense. Thanks, John.

CEL - Check Engine Light

CROSSOVER PIPE - Any type of mid-pipe which connects dual exhaust pipes starting from the cats

EGR - Exhaust Gas Recirculation system or valve

FI – Fuel Injection

F/I – Forced Induction

FOX BODY - A lightweight unibody architecture used on Mustangs built from 1979 to 1993

HiPo - The high performance version of a power adder which increases reliability and performance over the standard version

HID - High Intensity Discharge headlights commonly called xenon because of the gas used in the lamps

ID - Inside Diameter

IAT - Incoming Air Temperature sensor

IUP - Interior Upgrade Package

JUICE or JUICED - Term used to describe cars using nitrous oxide injection systems

LCA – Lower Control Arm

LSD – Limited Slip Differential

LT - Long Tube Headers

MAF - Mass Air Flow sensor

MANDREL BEND - A pipe bending method which reduces turbulence and increases flow because the diameter of the pipe stays the same throughout

NA – Normally/Naturally aspirated engine (No F/I)

NOS - The brand name of a nitrous system from Nitrous Oxide Systems. NOS is wrongly used to describe all nitrous systems thanks to the movie The Fast and The Furious.

NOS (when used with a part description) - New, Old Stock is a spare part which is new meaning never used, but the part may have been sitting in a crate for 50 years

o2 SENSOR - A probe that indicates precisely how complete the combustion of the air/fuel mixture in the cylinders is by measuring the oxygen content of the exhaust gas and is the starting point for controlling the A/F

OD - Outside Diameter

O/D - Overdrive

ODP - Overdrive Pulley

OEM - Original Equipment Manufacturer

PANHARD BAR/ROD - A bolt on bar which may or may not be adjustable that relocates the rear axle to the center of the car

PCV - Positive Crankcase Ventilation system or valve

RICE – Excessive combination of body panels, vendor decals, etc. You’ve seen them – usually cheap foreign cars with lawnmower engines and fart can mufflers (not to be confused with a RICE ROCKET which is very fast!)

RWHP – Horsepower measured at the rear wheel (on a rear wheel drive car) usually with a dynomometer

SC - Supercharger

SOHC – Single Overhead Cam

SHORTIES - Short tube headers

SNIFFER- Refers to Emissions testing

STALL SPEED - The engine RPM level at which the torque converter "locks" and overcomes whatever resistance is present - car weight, brakes on, etc. - and begins to spin the tires. The whole idea behind different stall speeds is to allow the car to launch at or just below the point where the engine makes the most torque. With the proper stall speed the engine can be revved to peak torque without breaking the tires loose. That way, the engine doesn't have to build up to the peak RPM point - all of the power is right there, on tap. The most important factors when selecting a torque converter is the camshaft, stall speed and weight of the car.

TAKE-OFFS - Stock exhaust, brakes, suspension or appearance parts taken off another car, usually a Mustang GT

TC - Turbocharger

T-LOC – A clutch/spring type of LSD

TB - Throttle Body

TORQUE CONVERTER - In automatic transmissions it takes the place of the manual clutch and is used to transmit power from the engine to the driveshaft. (See also STALL SPEED)

TRUE DUALS – Exhaust piping without crossovers

TUNER - Hand held device which re-progams the car's computer for greater performance and efficiency

TURN DOWNS - Exhaust piping turned downward directly after mufflers with no tailpipes

TRUETRAC - The brand name of a gear type LSD made by the Detroit Locker division of Eaton Corp

TT – Twin Turbochargers

UCA – Upper Control Arm

UDP - Underdrive Pulley

VERT- Convertible

WOT - Wide Open Throttle

Y PIPE - A type of exhaust mid-pipe, joining two pipes into one pipe, a second "y" can be used to split the pipes for a "fake"-dual exhaust setup

X PIPE - A type of exhaust crossover pipe in the shape of an "X"

 

very nice!

 

a very good resource... thanks for your efforts!

 

nice good job

throw this one in

O/D - overdrive

 

Thank you! Thought I'd give something back for all the stuff I learned from you guys.

John

 

DONE!! Thanks.

 

Can anyone reccomend a good book on how to learn what all this stuff is? Cars for Dummies maybe?

 

Thanks to everyone on this forum. I was looking for info about modding a Mustang I'm planning to buy and after reading all the tech language on these posts I was about to ask some questions about what you were saying. Most of my answers came easier after reading the definitions on this post. Thanks again.

 

This is an exceptional list!!! I would ask Prof to make this a stickey! I would also add:

TC: Turbo Charger
JUICE or JUICED: Term used to describe cars using Nitrous Oxide Systems
BOV: Blow Off Valve

 

I would try this:
