I'vce seen this on several sites and people say you gain power. I don't think you would. Does this gain any power?

 

No it doesn't give any hp and there are a few threads about this.

 

It doesnt give any HP, but it sounds sick

 

does not work on fuel injected cars basically. more of an upgrade for carburetor cars.

 

On one of the other threads a guy said he dyno tested one and it actually lost hp.

 

lol that's hilarious I cant believe sites are selling it if it loses power

 

people will believe it because it works on carburetors, but fuel injected is a different story

 

If people think it will work for them or believe that they will add power, people will continue to sell them.

Example: Look at the HP Chips on eBay, they are sold all day long. Also those cheap leaf blower electric superchargers, those have been proven to lose power, yet they are still sold.

 

soon ppl will realize that thew e bay ship will f up their car.

 

My friend installed on on his civic SI and he said he likes it. I dunno about gains tho... probably just in his head.

 

The premise behind this is that longer intake runners increases torque, which is true to a point [take a look at how long yours are].
The problem is, this doesn't lengthen the runners, it lengthens the plenum [making a long story short], which doesn't have the same effect.

That and the fact that Toyota designed the intake system to work together, so if you start modifying part of it, you're effecting how the whole thing interacts.

Yeah, they're useless on these [and most] cars.

This is a good example of finding the right answer by doing the wrong thing.
The point of these are to increase torque, not HP. Lengthening the intake runners can increase torque, but it will most likely lower HP [take a look at most high HP 4 bangers, they've got really short intake runners].

So this guy [the one that dynoed the car] thought he was being smart, but really had no clue what he was actually looking for. He got the right answer, but by dumb luck and not smarts.
Lesson; be careful what advice you take.
