list of items to replace for performance

[Nikku]

ok, what all should i replace to give me better performance/hp

here is what i know of

1.) Air Intake ( i just ordered a short ram )2.) headers/exhaust

i kno i will get better hp if i swap my engine. but i think i'd rather buy a diffrent car before i drop 3 grand into an engine swap. i have a GA16

Intake/Headers/Exhaust are the major NA bolt ons. Cams, but I don't believe anybody makes them for the 1.6. Other than hooking up some Nitrous, I don't see much else you can do besides weight reduction.

hey does this look legit?it tricks ur ecu.

what about this?

sry.... double post

[The 240 kid]

I could swear someone makes a header for the GA, but I have no idea who.

[nametakennow]

Both those "mods" are hardcore scams.

There *might* be an OBX header, seems like I've heard of one, but that wouldn't make a whole lot of sense since OBX's are generally Hotshot or other large brand knock-offs.

i kinda figured the second one was fake, but the first one makes since. why do u think its a scam? for 10 bucks im kinda curious unless u guys can prove it wrong?

i mean if u read the feedback these people get on these "mods" people are saying it works

[The 240 kid]

The first one I've heard is a scam, and I know tornado's aka vortex ... do NOT work! Sport Compact Car did a dyno and actually lost 1 HP I think.

hey whats year is ur GA16?

[nametakennow]

Ha, those are fake people that have it, or idiots.

What it does is tells your ECU that your intake temp is colder than it actually is. Your ECU then ups the fuel a little to compensate.

So, what do you have? A slightly rich engine with fewer hp and poorer gas mileage.

That's the short version.

wouldnt it give u more hp? the only complaints on these "mods" is that they dont like to work on the dodge stratus, and the fact that all the mod is, is a 100k ohm resistor, but people are saying it increased there hp, i doubt it increases 20hp but maybe a little.

another question. if i replaced the stock cat would i get more hp? people are saying if u get a "test pipe" ( wich seems like its just a hollow pipe ) then its suppose to give u better performance.

what do u guys think?

Test pipes reduce exhaust restriction, but also make your car illegal if you have emissions testing.

Again, this device tells your ECU that the air coming in is colder than it actually is. The ECU bumps up the fuel accordingly. Combustion takes two to tango, air+gas. More gas is not synonymous with more power. Your car seeks an a/f ratio somewhere in the 14s (though not the optimal 14.7:1 ratio, because a little slip up means you're lean and that leads to damage... manufacturers don't want to be responsible for that, so they tune cars slightly rich). If you tell it the air is colder, that ratio dips even lower towards the 13somethings:1. Thus, your car's combustion is even further from being optimized, you lose power and $ in gas.

Yet again, those supposed "buyers" either are the seller or his friends disguised as other Ebay'ers, or are complete morons who fell for the placebo effect of this "mod."

It really, seriously, doesn't add power. If you doubt my credibility, bounce around the forums a little bit and see what you find about this "mod" and my explanation.

Oh, and if you really want to try it, why buy it on Ebay? Radioshack has resistors. Go buy 100ohm one for a few bucks, solder it in, and realize how much of a waste of time and money it was.

edit: I'm sorry, if you actually believe this, you need to start reading - http://howstuffworks.com.

Today's vehicles are required to produce less pollution. The way this is done is by regulating the ECU (the computer) to reduce emissions. This affects performance by reducing the amount of fuel, air and spark being delivered to the engine. The factory settings govern the ECU to mix a specific amount of fuel and air more favorable for emissions and not performance. Our Performance Mod increases your air, fuel and spark ratios to the optimum OEM level in turn you get -- Better Throttle Response throughout the RPM Range -- Increased Torque -- More Horsepower. Complete combustion means less wasted fuel!!

The first two sentences are true. However, automakers don't reduce the fuel, they use timing and other emissions devices (EGR, precats, etc). Your car's a/f sensor isn't terribly exact, so to save money car companies tune cars to be rich so as to prevent accidental damage from lean conditions, as I said before. This "Performance Mod" does not increase anything other than resistance between the IAT sensor and your ECU. ECU ups fuel, and thus car runs richer. There will be no timing advance, the difference isn't big enough to cause that. Changes in timing reflect throttle position and rpm moreso than intake temp.

what is said makes sense. fooling the ECU doesn do much good. having more fuel in da combustion chamber doesnt necessarliy mean more power. combustion is most efficient at the right ratio of air to fuel. if you have to much air, u might not get enuff power to push the cylinder down or the mixture might not ignite... and if u hav too much gas, it may not ignite properly. ur gonna end up wasting ur money. and its not a bad idea to read how stuff works. it does help u out for alot of things.

umm, i kno that last sentence wasnt used sarcastically, cuz from the way u inform, u dont sound like u kno much about what your talking about ether.

[B13@15yrszold]

well ii knoe how the whole cumbustion system works, ii studied it in school, that where ii learned the basics. ii juss didnt knoe how to explain it clearly. and no it wasnt used sarcastically, because ii still find myself going there if ii dont remeber how something works or if i'm trying to fix a problem on da car.
