Removing the Air Sliencer? Whats it do?

[lordofillusions]

Can someone explain to me exactly what removing the Air Sliencer does? My dad was questioning everything i was doing when i was taking it off today. He doesn't think that it will improve it at all. Did i miss something? I removed the silencer....is that all there is to it? or was i supposed to do something else too?

it does absolutely nothing for performance, but it will give it a throatier sound, if you're looking into doing cheap mods start out w/the cold air intake (no more than $20 + filter) They have links all over this forums on how to home make them

Allright, thanks. Yea i was thinking about the Cold air intake, i plan on doing that. Has anyone actually noticed a throatier sound from removing the silencer? I just removed it today, and im planning on getting a new muffler soon too, i really want to improve the sound. Get that throatier sound, but as cheaply as possible. My Dad is trying to tell me that by removing the silencer i've screwed up the engine because its set at a certain amount of air and fuel and now that i've taken the silencer out i've screwed it all up. Anyone know how i can explain this to him?

I'm sure others can explain this better than me but I will try. I'm guessing your car is fuel injected also.

Most Fuel injected cars use sensors to adjust to fuel and air ratios. On my 93' 2.3L LX has a MAF ( Mass air sensor) bolted to the air box that is used to adjust the fuel injectors to the incomming air. It also has another snesor called a ACT which helps also. Anyways the sensors talk to the EEC and fuel injectors that then adjust for any changes in the air flow. Most people who use Nitrous loves a EFI car because it will add extra fuel when the MAF/air sensors pick up on the added air unlike a carb motor where you have to use bigger jets.

what I noticed and a question

As I noted in another thread, I just removed my silencer from my '93
LX 2.3L NA and I noticed two changes; 1. In neutral the motor will increase in RPM's quicker when you press the throttle than it did before, and 2. Before the removal I couldn't spin the 235/60 15 tires without dumping the clutch but now I can. (On dry pavement I mean) My question to the experts is this,
When I make a CAI is there a rule on the distance between the sensors ( currently at the air filter box) and the throttle body? Or, can the sensors and vaccum hoses be moved next to the throttle body to free up the design of the CAI?

P.S. I hope to get a header and 3" exaust in the future,
that should help with power and sound, huh.

Darth, 3" will be WAY to big for a naturally aspirated 2.3. 2.25" should be more than enough.

I agree.

As for the sensor, I think if you got a ACT sensor it needs to be down from the MAF about a inch. That is all I can think of but why go through the trouble of relocating the sensors if your still going to have a tube going to that area to collect cold air anyways?

thanks


Thanks, for the help?
On the exhaust size, I had mentioned 3"
because the header I was looking at had a
3" collector. But I have learned that it would
actually rob me of power. thanks for the suggesting the proper size.
As for the sensor location; it was just a curiosity question, I noticed
most of the pvc cai's maintained roughly the same distance and wondered
if they had to.

thanks, Darth
