cat = catalytic converter

precat = catalytic coverter that comes right after the turbo - part of the stock "down pipe"

main cat = catalytic converter in the middle of the exhaust pipe, under middle of car

TPS = throttle position sensor

ISC = idle speed control

VA = vacuum advance

psi = pounds per square inch - usually used in reference to turbo boost, vacuum, or tire pressure

RPM = rotations per minute - this is displayed on the tachometer

bcfpr= boost compensating fuel pressuge regulator

 

shp=sport handling pakage

tt=turbo timer or twin turbo

dis=direct ingnition system

mpi=multi port injection

tbi=throttle body injection

na=normally assperated(no turbo or super charger, all motor)

nawz=means your a moron...he he

o2 sensor=oxygen sensor

SQ=starquest

no2 or NOS=nitrious oxide

IC=intercooler

DP=down pipe

BPV = By-pass valve, like a BOV, but the BOV vents to atmosphere, the BPV vents back into the intake tubing just before the turbo and after the MAS.

 

MAS/MAF = Mass Airflow Sensor, or Mass Air Flow.

 

1G(as used here) = First Generation, some state it refers to DSM(see next entry) cars as a whole, I state it stands for the 1st Generation of the Eclipse/Talon/Laser cars. Generally when a car is stated as 1G, it's the first ever body style/design of a specific car that lives long enough to be retooled over and over again, Such as the Corvette, Eclipse, RX7, Camaro, etc. etc. There is no Generation designation for the S/Q as it's only design was just cosmetically changed over the years, no major body/chassis change was ever implemented to create a 2G S/Q, thus necessitating the need to call the originals 1G.

 

DSM = Diamond Star Motors, a joint venture between Chrysler and Mitsubishi that produced cars such as the Eclipse/Laser/Talon, Stealth/3000GT etc. etc.

 

 

To add to that,

 

1G BOV, would simply be the "BPV" off of a 1G Eclipse/Talon/Laser TURBO, as the 1G BOV as everyone states it, was actually designed to recirculate the air, and not "Blow it off".

 

1G MAS, is the Mass Airflow Sensor from the 1G Eclipse/Talon/Laser TURBO's. This always refers to the Turbo versions, as the NA versions are useless to us.

IWMSL: I Wet MySelf Laughing, ;D

KYBO: Keep Your Bowels Open, nick name for an outhouse, pronounced Kï'-bõ... :P

MAP: Manifold Absloute Pressure (sensor),

More later...

Stoich: Short for Stoichiometric, which in our case refers to A/F ratio. A Stoichiometric chemical reaction is one in which all the reactants are used up most efficiently. So, Stoichiometric A/F ratio is that ratio which is just right: around 14.7:1 by mass, but this varies with load and compression and other factors. If your engine is running stoich then it's being as efficient as possible. Stoich is what the ECU strives for in closed loop operation.

 

Closed Loop Operation: When the ECU uses info from the O2 sensor to fine tune the A/F ratio.

 

Open Loop Operation: When the ECU ignores the O2 sensor because it can't be trusted or isn't practical under certain conditions, such as engine warmup, hard acceleration, deceleration, ect.

Hey KO, that page said the Max overbore is .040 over. There are stock replacement pistons that go up to .060. Of course that is the max anyone could ever even think about going! He He!

IAC = Idle Air Control (Valve) - A stepper motor that controls the amount of air allowed to bypass the throttle plate. (A choke)

 

PFT = Pretty $%^ing Tight - A torque specification used by rednecks and shade trees when tightening fasteners. Usually results in finding the failure tolerance of the fastener or casting.

 

That what you had in mind? :)

I can't believe this one was missed!  The most important one! :o

 

WOT=Wide Open Throttle!!!  ;D

 

As in, "after sufficient break-in time is allowed, always drive your quest at WOT for best results!"  ;D

maybe it would be helpful (To me at least) if you'd put what the thing does too, or at least a short description.  Ie.

 

BOV =Blow off Valve,  blah blah exhaust blah.

 

i think you mean intake. not exhaust. anyway heres a few

 

pitboat=primus is the best of all time

ac-air conditioning

ford-found on road dead

mustang- mostly used soupin^to anilhaite nothing great

 

sorry i had to mkae sum up cuz there was next to nothing left to use

BCFPR = any plain old freaking fuel pressure regulator. this is a term used and created by Ricers.

 

there are 3 type of pressure regulators:

 

1. RRFPR (aka FMU) fuel management unit

2. adjustable fuel pressure regulator

3. non-adjustable (factory type) pressure regulator.

 

2 and 3 could technically be called boost compensating when used on a boosted car.

whatever that means. as if one could use a can of yogurt instead. every freakin car has one yet stupid vendors try to toss in that term into the description of their crappy pressure regulator to make it seem like its something more.
