hp adders??

[EliteImports]

i need more HP... i know the basics...

minor HP:
intake & exhaust
headers

major HP:
supercharger
turbocharger
NOS

what else is there besides bore & polish the engine or an engine swap? i know this sounds like an ignorant question, that's because i am just starting to learn engines... please help.

disconnect your air conditioner they wont gain hp but it wll give you more usable power get an aftermarket air filter pretty much everything aftermarket serves some purpose so get an import cataolg and find what you need

[igo4bmx]

new cams and cam gears
intake manifold

There are only two ways to get more power out of your engine to the road.

1) Burn more fuel/air in a given amount of time
2) Transfer the energy to the wheels more efficiently

Under 1, you're looking either at adding displacment, improving induction, or upping the redline - that's all.

Engine Swap
Changing displacment through bore and/or stroke mods
Intake Cam adjustment/replacement
Replacment head
SOHC VTEC crossover adjustment
CAI, intake port matching, etc.
Forced Induction (Turbo, Supercharger, N2O, alchohol fuel, nitromethane fuel, etc.)
Valve springs, removing rev limiter, other high rev adjustments (usually requires new head and other internals to truly take advantage of much up here.)


2) OK, well, there's a great deal to play with here

Disconnecting accessories
Exhaust cam adjustment/replacment
Exhaust system mods
Replacment head/exhaust port matching, etc.
Fancy oil (e.g. RedLine Manual Transmission Lube)
Auto-Manual tranny swap
Smaller, less springy tires (yes, that gives you more power on the ground)
Ignition systems
Ignition timing


There are also modifications you can make to use the same amount of power to make the car go faster:

Weight
Handling
LSD
Bigger, stickier tires
Shorter gearing (often though the use of smaller diameter tires for track applications)

Have I missed anything?

damn it, that's what i'm talking about... i recognize some of that, but some of it also seems to be way above me...

LSD? i think you're right, on LSD i probably would think my car was flyin! seriously, whats LSD?

limited slip differential, it uh tries to keep the wheels from slipping...or sumthing like that

its also a fuel additive that gives temporary speed "highs"

[shorthand]

LSD = Limited Slip Differnetial - jaxle is right

The differential gear is the gear assembly that allows one drive wheel to rotate at a different speed from the other. Before the differential was invented, cars used to only power one wheel.

A limited slip differential prevents one wheel spin. This is particularly insidious on front wheel drive cars where the inside wheel will spin badly when turning sharply. When this happens, almost no power is transmitted to the ground.

An LSD has a clutch-type mechanism between the two different half-shafts that prevents excessive slip while still allowing the wheels to go around a curve at different speeds.
