Alright...i manned up and decided to post it. I need the definition of a few words....cuz i got no clue they mean....any help is appreciated, and dont rip on me to bad
What do these mean:

-Low-End
-High-End
-Differential
-IMO
-Mini-Me Swap
-Compression
-And could anyone explain to me what the air/fuel mixture(ratio) actually is?


Thanks everyone....[&o]

 

Low-End: Low RPM ranges, you make lots of torque

High End: High RPM ranges, you make lots of HP

Differential: Allows the two wheels to spin at different speeds through a turn. Uses a pinion gear and a ring gear.

Mini-Me Swap: Installing a VTEC head on a non-VTEC engine block

Compression: The volume of the cylinder divided by the volume of the combustion chamber. The higher the compression, the more power you will make and the more likely it is for the fuel to detonate (ignite without a spark).

Air/Fuel Ratio: The ideal A/F ratio is 14.7:1 (thanks sacs). You want to have 1 part fuel for every 13.7 parts oxygen. This will yield a mixture in which all the fuel and air are used up perfectly. Rich fuel mixtures contain extra fuel and Lean fuel mixtures contain extra oxygen. Lean fuel mixtures tend to blow engines due to the high heat they create.

IMO: It stands for In My Opinion

 

I got a question what is Bump,I see it some times in peoples replies.

 

YOu have to post a message to get your thread back to the top of a forum section. So instead of typing messages, people choose to just type "Bump" or "To the top"

 

its 14.7:1. but also, remember that you dont really want to go higher than that because you risk detonation, which destroys motors. usually they tune lower than 14.7 for safety. and forced induction cars need it even richer (numerically lower) ussually around 12:1-13.5:1, depending on how much boost.

 

What do you mean by head? Like header/exhaust manifold?

 

This should be a pic of my d15b7 motor no vtec head.

And this is the block it goes on the d15b7 block.It goes on top with a head gasket.

just to clarify, the head goes on top of the headgasket and block, not the other way around:-D

The head is where your camshaft and valvetrain is, the block is where the pistons, rods, and crank are found...

 

thats true, i am doin a mini-me to my car soon!!!
