I've been searching about various different intake setups and noticed that some people choose to use a straight MAF-TB pipe, thus eliminating the stock Helmholtz resonator.

Some people say there are gains to be had here, but I've read another thread where someone said that the Helmholtz resonator actually gives the best power-band of all.

Does anyone have some insight on this?

It is better to keep the resonator or get rid of it and use a straight pipe?

I've searched and searched and it seems that this particular question has never been answered.

 

I personally have seen better response through out the power band with the resonator removed on my dek. This is with the butt dyno of course. And the sound is amazing without it.

 

IMHO anything designed to make the car quieter will rob you of some horsepower. It's a resonator after all.

 

For a daily driver, it seems IMO to be too loud for the possible slight gains you might get removing it. The roar at WOT reminds me of some F1 race car or something. Ridiculously loud.

I still have the Helmholtz to MAF, then a stright pipe to cone filter. I think the sound is much better produced from this set-up than w/o the Helmholtz.

 

I've read up on this and couldn't find a ton of info, so hopefully someone will chime in on it.

I think that the tube and box that goes below the battery is for noise.

The big piece between the MAF and the TB, I don't know. I've looked inside mind and there are no obstructions or anything that would block airflow (like a muffler), so it doesn't seem like it would reduce performance significantly. It's just like a straight through tube with a few openings.

Subscribed to see how this goes.

 

I see where the idea of "if it quiets the car down, it robs horsepower" comes from.

I just thought that the resonator was sort of analogous to tuning a sub-woofer box to a certain frequency.

And I read somewhere about it creating a "pocket of air" or something?

 

I removed the resonator and it's only "loud" when u get into the throttle pretty good, if I had to guess I'd say 3500+...it sounds great and with everyday commuting I don't hear a huge difference. When I initially left it on and had just the TB and filter it wasn't any louder than my GAB.

 

That is exactly what is was designed for and exactly what it does...

 

I read about the Helmholtz purpose and My understanding was for some sorta of tuning Frequency for the intake manifold and smoothing out the turbulence @ the IM entrance...I'm still running mine and it freakin pulls hard with a small V8 like rumble at part throttle and WOT(mostly the headers/exhaust)....
