    Power Resonator MANTZEL. Did You know about?

    I have it in my car and I'm really happy. The engine works better in the lower rpm range, power resonator system eliminates the negative bottom multiram. Necessary to keep the air at fast throttle opening.

    I have seen them on Opel and Vauxhall Omegas and have a few pictures of them in my album. Do you have one on your car? The Multi-Ram on my Catera works fine. How is the Mantzel better?

    I think I've answered both our questions. Mantzel claims to add 14 HP and 15 ft pounds torque to the Omega V6. Remember, the Catera normally gives up 20 HP to the Omega so if it's true it could bring us closer to their power.

    Their site is in German but Google Translate says:
    Mantzel's contribution for the improvement of the Omega B V6 engine. One very simple component to be fitted to a control valve replaced the original intake system. Reached, when the filter is changed according to our cash data with a power increase of up to 14 hp and an increase in torque by 20 Nm. The engine is better on gas and is much more agile. At the 3.0-liter V6, it is necessary from the 1998 model to replace the air manifold and the throttle body against the model to 98. The Powerresonator has for the 3.0 liter automatic one part approval. All other models must be registered by us on site at the TÜV. The Powerresonator not fit in the front-wheel drive V6 engines.

    As to where to get one here's one source:

    Re: Power Resonator MANTZEL. Did You know about?

    I have one The only problem with mantzel is that when you stop the car the power resonator heats up and you can not protect this device thermally. The warmer air the less of it and the engine gets air not so much. I changed on copy Mantzel (my friend makes copies in free time) properly prepared and is better than I thought the engine has gained new life and soul.

    Re: Power Resonator MANTZEL. Did You know about?

    Man, 1k bux.... =/ It states to use a valve. I wonder how this valve differs from the stock multi-intake system with it's valve(s)? I looks to onmy replace one of the valves in the stock system? Maybe just a better fine-tuning? Hmmm,....

    Here are pictures of the Dual and Multi Ram intakes as well as performance intakes. Mantzel, Steinmetz, Irmscher, and homemade resonators. I wish I knew what was inside them. The original Ram Systems have solenoid controlled butterfly valves activated by the ECU. These resonators don't seem to have any electronic components at all. They must have some kind of baffles or passages inside. They can't just be empty boxes that increase power by 14 HP and Torque by 15 ft/lbs.

    is empty inside. Very important is the dimension of the box, and diameters of holes.
    Mantzel really reduces the long column of air and causes it to provide faster and more.

    Re: Power Resonator MANTZEL. Did You know about?

    Would you measure your resonator and give us the dimensions and diameters? Maybe we can make our own. There are no performance accessories for the Catera engine over here and I'm sure many owners would like to add this to theirs.

    Elvin I found the following when I searched in Google but may need first hand verification,



    The picture aspect ratio may be skewed.

    Apparently these are totally empty boxes hence the skepticism.

    Hope it gives some info.

    Those drawings would be for the 97 or 98. I assume that everything is the same for our 99 up motors, minus the vacuum line outlet on the left side of the box.

    Re: Power Resonator MANTZEL. Did You know about?

    This resonator or any homemade type resonator would rid the multiram system correct? Or at least the Resonance Switch-Over Valve would be eliminated. If so then would it really make a difference? All it looks is that these resonators are just reducing the intake ducting. And since the piping on our cateras are so ridicously long with many twists and turns, i'd imagine it would help alot, but without axing the multiram. All I want to do to mine is to reduce the intake tubing while keeping the entire exsisting multiram system somehow.

    I know that if you remove the airbox on a motorcycle and replace it with individual airpod filters you loose power & torque forcing you to rejet the carburetors. The airbox provides a pressure wave that forces more fuel mixture into the cylinders when the intake valves open. I assumed this was the purpose of the plenum sitting on the intake runners of the Catera/Omega engine.

    I did some research and came up with the following. The main benefit of using an airbox and intake runners is a small pressurization of intake air. That's because the airbox is a Helmholtz resonator. That is, a resonance effect occurs when you connect an enclosed volume of a suitable size and shape to an engine’s intake stacks causing the air inside to resonate at a frequency that results in pressure peaks which coincide with the cylinders’ intake stroke frequency (at a particular RPM.) This can theoretically increase power by 10–15% within a particular RPM range by boosting airflow into the engine.

    Airboxes need to be well-sealed and stiff in construction to maintain these resonance characteristics. A simple way to illustrate this is to blow across the mouth of an empty bottle. The sound you hear is the natural frequency of a Hemholtz resonator. If you change the shape and free air volume of the airbox, you change its resonance frequencies, and the engine RPM at which it responds to enhance filling the engine with air. If you fill the empty bottle with filter foam (mostly air) and blow across it, you'll get no resonant frequency sound at all.

    An airbox also functions as a plenum, a space where the air velocity is reduced so as to eliminate turbulent airflow prior to being smoothed and accelerated down the velocity stacks. In fact, if you just place your finger anywhere near the edge of the top of the velocity stack you'll see dyno power dropping off due to the disturbed air flow pattern. The air in the plenum is also considered "free air." That is, it’s already passed through the filter and air tract so it can be supplied to the engine without any flow restriction. Our engine has a separate plenum so I guess the "airbox" is merely a filter housing.

    If you use the auto industry's standard calculation of air required for free flow within the air intake system, you should have at least 130% of engine capacity in available air volume between the throttle butterflies and the air filter element. This means for the best results from our 3.0L engine the air volume of the the intake tract, beginning at the airbox and ending at the throttle bodies should be at least 3.9L.

    Since the Mantzel Resonator has no moving parts it must be tuned to a specific air velocity, probably at wide open throttle. Anywhere else on the power curve and performance must drop off affecting low speed driveability. The factory dual and multi ram systems must be designed to adjust the air velocity to the engine RPM and provide peak performance across a wide RPM range.

    After all this I think I'll stay with the Multi-Ram on my car. I already have a K&N filter pod in place of the "airbox" eliminating the tubing starting in front of the radiator and ending at the MAF sensor. I don't feel much "seat of the pants" improvement but I think the engine breathes better. I'll leave it to the street racers and hot rodders among us to test a "resonatorized" Catera.

    elvin315 great write up.

    Thank you.

    PS: How did Cadillac de-tune the Omega to rob us of 10HP? Is it mechanical, ECU programming and mapping, MAF or anything else or a combination of many? Not trying to recover just wondering.

    It was computer programing. Emission control and what-not.
