I would like to build my knowledge on all engine parts- what each part does...
throttle body
valves
cam gears
flywheels
straightpipe
etc. Is there a website i can go to learn all this information. Apprec.

i can help!

throttle body
Located at the end of the intake tube, first part of the intake manifold. contains a throttle plate (butterfly) which modulates air intake into the engine.

valves
Intake and exhaust valves rest in the head of the engine. They control air going in and out of the cylinders. These are actuated by the camshaft (s).

cam gears
Gears usually located on either side of the engine block. They are directly connected to the camshaft(s) mentioned above. Cam gears are spun by a timing belt (chain in our cars), which is driven by the motor.

flywheels
Engine side of a clutch assembly. This is what presses against a clutch disk to engage your clutch. People want lightned one to reduce rotational mass, meaning faster spool up and more power (generally... less mass the engine has to turn, the more power is freed up).

straightpipe
Aftermarket pipe that directly replaces the OEM catalytic converter (cat). The 'cat' is there to reduce emission by using a catalyst to transform nitrates into safer gasses. THe cat is pretty restitrive of exhaust air flow, so ppl want straightpipes... this is against the law though. in california = min $1000 fine. you will also fail smog.

next!

but yeah, howstuffworks is an excellent start!

and they provide cool animations for some of this stuff. That site is where i send my sisters and gf/female friends when they ask about car stuff. Me trying to explain this stuff to them gives me a headache...."well what does that thingy do???" *i give answer* "well why do you need it?" uuuuugh!

Thanks for the website. I will look into it....but i was also looking for websites that can show me specs...
like exhaust in general will ad 5-15hp, Air intake 3-10
-but i know this info from just reading the forum

Id like to know what all the more complex thing do like
By adding new camshafts- will this cause a hp increase
or by new injectors, flywheel?
Can you attach a straight pipe to stock exhaust- will it increase hp?
etc.

Thanks

Much better attitude.!!
Congrats.!!
So,from now on,you will know,what you're talking about.
A little....

By adding new camshafts- will this cause a hp increase
--yes, but our factory cams are quite agressive, you wont realize much more hp, and will sacrifice reliablitly

or by new injectors,
--no, bigger injectors will allow more fuel to flow, but the ECU will not allow it. You only use bigger injectors when you NEED it, I.E. Forced induction with +8lb boost.

flywheel?
--didnt i explain this one already?

Can you attach a straight pipe to stock exhaust-
--The straight pipe is not part of the stock exhaust, the cat sits between the exhaust and header, so yes.

will it increase hp?
--yes.. didnt i explain this already too?

etc.
