How many of you have removed your intake resonator?

the resonator is just making the engine sounds quiter by restricting the air a bit---> you lose power
remove the resonator you will get more power and sound

it is just like removing the CAT... you remove parts that restrict air flow into and out from the engine to keep it breathing freely.

Has anyone got back to back dyno numbers that show a power gain or is just a noise gain? Part of the resonators job is to make it quieter for suer. But, a resonator will also help fill in the torque curve if properly designed. #'s anyone?

the gains are real... no dyno proof but i can tell when my car is faster, you are right about the torque thing... the resonator ands CAT rermoval might affect your torque but it will add to your HP so you are adding to top end on the expense of low end.

deciding if this is a helpful mod or not depends on how you drive, i rev the engine hard so better breathing is a must.

Actual data figures would be good to see. I can tell you from my own experience removing the res made the performance worse at the low end RPM but I do drive mostly in city traffic. To be honest, even at the top end I didn't really notice that much gain to warrant its removal so I put it back.

It would be too hard for me to tell if the resonator removal gave me much if any HP gain since I also did a SRI at the same time.

physics tells you that it would give you a gain...

there is a pressure drop across your entire intake (that is to say a slight "vacuum"). the less volume you can make the system, the better the flow in general. if you remove the intake resonator, which is nothing more than a huge box, you are pulling a very harge restriction out of the system.

I tweak Motors too, and even before I discovered 'Wootech, I stripped it out.

100% sure you will notice it works better.

Like Audacity says, the vacuum is formed by something, and that "something" is energy used to draw air into the Block.
Think of it this way... a turbo uses surplus energy to force air into the Cylinders..... and look at that for increase...........

As with all tuning...... every little bit counts when you add it all up. Want more!!!... eliminate the energy sapping parts!!

Are there other energy sapping parts I should know about too?

the CAT but depending on where are you living this could be illegal.

its only illegal if you get caught

By CAT, do you mean Catalytic converter? I checked... CAT isn't listed on your list so...

C Celsius
C/L Closed Loop
C3 GM ECM using Motorola 68xx-like processor (1+ MHz CPU)
CCP Controlled Canister Purge
CEL Check engine light (see MIL, SES)
CID Cubic Inch Displacement
CKP crankshaft position sensor
CMP camshaft position sensor
CP Canister Purge
CPU Central Processor Unit (the brains in the ecm)
CTS Coolant Temp Sensor

Yeah... Hmmm... I know that it's illegal to have no catalytic converter here in Michigan, but I think there is a special FlowMaster one I could get if I want to help my engine breath better. I will most likely change that out when I upgrade the rest of my exhaust.

yes the catalytic converter

I removed my intake resonator, but i didnt really notice a louder sound or much more power like you guys were talking about. At 2,500rpm i notice a little bit of a purrr but it could just be me listening for a specific sound change. What sound is it supposed to lower? i mean its just sucking in air

did you floor it during testing?

Ok, I'll be getting THIS: http://cgi.ebay.com.au/ws/eBayISAPI.dll ... 4617142504

For those of you who ignored my post.

So my intake resonator will be removed.

Currently is http://www.users.on.net/~hoogs/daewoo/03.jpg , so that'll give you an idea of the restriction I'll be removing.

Paying for it on Wednesday, so I'll let you know how it goes.

Mine is done. That was the first thing i did.
