All motor Definitions....
Can we get a thread going that defines terms used in this forum some people might not understand.
Example:
Shot Peened ( I just looked this up because I didn't know)
Shot peening is a process that involves the bombardment of metal parts by millions of essentially spherical particles for the purpose of totally preventing or greatly retarding the failure of that part.
Benifits
-Fatigue life is enhanced significantly increasing life of the part
-Surface hardness is enhanced
If anyone else has anything they want to contribute please do.

High Compression Pistons (noun)
Pistons which exhibit compression levels higher than that of stock. Higher compression usually yields more horsepower in all-motor applications.
Benefits:
More Horsepower!
Cons:
Higher Octane Gas Possibly
-----
DOHC VTEC Sticker (noun) - A sticker/decal that came stock on 1999-2000 Honda Civic Si that enthusiast buys to enhance the appearance of their car.
Benefits:
Makes your car look better.
Cons:
Some ricers actually believe that this all-motor mod adds 10HP to your car.

Re: All motor Definitions.... (cpforyou)
Displacement.....
More = More Power
Pro's... go faster...
Con's.... Can't rev as high... due to higher stroke to rod ratio... takes more to move all the parts... and unless you have crazy internals... you can't revs as high as smaller displacement motors..

UPDATE:
Displacement (noun)
The volume taken up by a single stroke of a piston in an engine or pump.
Mathmatical Model
Hypothesis is that more displacement = more torque
Proof: HORSEPOWER = TORQUE * RPM / 5252
Theefore by increasing torque, at any given RPM, the horsepower is also increased.
----------
Methods of Increase Displacement
BORE OUT!
Pros: R/S Ratio stays fairly he same.
Cons: Thinner Walls
LONGER STROKE!
Pros: Walls stay the same size.
Cons: Worser R/S Ratio in general.

Re: All motor Definitions.... (Irishweird00)
Venturi effect By definition it is a tube with a constricted, throat-like passage that increases the velocity of the air passing through it
-think intake runners
Pros incresed velocity of the air entering the engine
Cons there is a restriction in the intake stream
thats the only thing that popped into my mind

Re: All motor Definitions.... (GetawayinMoscow)
boring- increasing the diameters of the cylinders, wider pistons are also needed, and most likely the combustion chambers must be matched also
honing-polishing the cylinder walls
how compression ratio is calculated- there are 2 ways corrected and uncorrected, but i dont feel like explaing
bore-diameter of the cylinder
stroke- distance from top dead centre to bottom dead centre
