I have ordered a Mac Pro-Chamber... I'm creating a new thread, because I believe that the events which are about to unfold need some type of chronolgy to be written...

I am upgrading from a MagnaFlow X-PIPE.. I am really happy with the XPIPE, but feel there is still some un-tapped tone left for the SOHC 4.0.. Suffice it to say that the swap is based purley on the tone of the engine which is the main focus.. However, accompanied to this is a possible improvement in low end torque, and high RPM tone enhancement..

What this means, in terms of tone, is based on the design of the Pro-Chamber, it is my belief that a deeper tone at higher RPM can be achieved based on design alone..

How this will effect lower-end torque and HP has yet to be seen.. All of you V6 nuts, and fanatics have the priveledge to use me as your very own PIG.. Thats right, I will sell out the XPIPE design for a Pro-Chamber, in order to proof positively tell you which is best.. I have run the XPIPE for quite ahwile, and can vouch for its success in terms of sound tone on the SOHC 4.0.. With my move to the PRO-Chamber, this should reach the pinnacle of my testing sessions, which the ability to recommend the absolute best in terms of sound production available from the 2005 05V6...

Keep you fingers crossed.. This promises to be the most exciting sound re-production ever heard from the 2005 V6 Mustang..

The session will round out with a quick sprint onto the freeway from 0 to 110MPH.. Or a 1st through 3rd, high revving freeway merge and quick exit.. If I can strap in the Camcorder into the passenger seat, I will..

I am waiting for the product to arrive, and then will have it installed.. Should be all done sometime next week, late.. If not the weekend after.. Dont buy any Exhaust parts until you see or hear this new innovation for yourself.. I am commited to the excellence of sound created by the SOHC 4.0 in the Mustang.. This is the utmost in terms of credibility.. We cant convince people we have mean sounding stangs, with the stock exhaust... We gotta get down and dirty with it! With this experiment, we are gonna get down and filthy my friends.. Stand By!

 

What is your time frame for install/testing. We talking 2 or 3 weeks here, I assume that the unit will not be in for about 5 days via ground shipping. Also, will you put in MAC headers along with this project at any point? Perhaps for a phase II?

I know you have a FRTOC and gears, but other than that the only MOD on your car is the exhaust system? Are you running a tuner or CAI? I read that the CAI will have a slight impact on sound in terms of it being a bit louder.

Thoughts?

 

My car is Bone stock, RaginStormLock... No tuner, or CAI.. Just exhaust for now.. When I go, I like to go big.. So until then, I will fiddle around with the bare essentials... I dont like to nickle and dime it.. To me, a tune or CAI are nice, but not before bigger items.. So please except this humble experiment as a gift to you from me.. LOL!!

I am just a small player unlike you and Jimp, and Scrming.. But once I pull the trigger, the blast will go BOOM.. But consider me not much of a threat to anyone here..

 

Cool! Any thought on testing it with MAC headers later down the road...as part of your gift to us.

 

I wouldn't expect much power from a prochamber/x-pipe. 5.0 tried one of these on a GT and got maybe 2 HP. I think it would be nada on a V6. If you take the cats off you might get 6 HP, give or take. I think you're right about the sound quality changing.

 

Yes, not really looking for any HP gains.. Since the ProChamber should give more backpressure, it shold move the torque back down to the lower RPM range, as opposed to the mid-range of the XPIPE..

The only reason I'm doing it is for the sound change.. Thats it.. In terms of power your right, the Pro-Chamber and XPIPE are about the same..

@RaginStormLock

I will get the LongTube headers soon.. I just want to get the headers, and not the complete $1000 exhaust system.. I just need the Long-Tubes, and have my guy down at the shop adpat my existing system to them..

 

Hey guys! Gotta quick question, whats the standard time for smog recertification? Is it 2 years for new vehicles, or longer?

 

Here in DC, it is 2 years for recent/new vechicles, and we follow the same guidelines as CA.

 

I guess you can figure out why I'm asking.. I am just curious is all.. I am really interested how the car would sound straight through... With the Pro-Chamber in place, does the 4.0 V6 have what it takes to truley re-create the sound of a V8? I think with the STAC removed, it just might..

Now since I will be adding the headers on the folloing trip, I might test it out for awhile without the STAC.. Just so we know exactly what it sounds like.. I can put them back later.. I'll think about it...

 

Yea, I figured as much. Be careful, it might sound so good that you wont want to put them back on. Though I can't wait to hear how it sounds.

 

I will put them back.. Since I know I need to make two trips for this adventure, and the system will have to be reconstucted anyay once I put the LT's on..

I'm not sure yet though.. It may be too much trouble for me to remove them at this point.. We'll see...

 

I looked up some technical details on the H pipe, and how it generates sound, here is what I found in this months article of MMFF:

"......Now the high and low pressure pulses on the left bank get to become friends with those on the other bank. Not only do the sounds mix, but the low pressure pulses on one bank actually help draw out the hih pressure pulses on the other. Quasi-static scavenging, we call it. Makes more torque, smooths things out acoustically. "

And here is what the article said on the X pipe:

".....the X pipe does exactly what the H piep does, but better, different. Instead of just letting pressure pulsations (a small portion of exhaust flow) bly back and forth across the H tube, the X pipe makes sure that all the exhaust gas from each cylinder bank gets very intimate. To things to understand, destructive interference and dynamic scavenging....

....That is why your X pipe sounds different than an H pip. Less modulation, less low frequency contribution, just 4th order starting off low and rising to a shriek at the top of the tach. It's smoother too, since the enrgy associated with the bank to bank pressure fluctuations is used more effectively to scaveng the exhaust gases"

So it proves your theory, and also proves that the X pipe will make more power than an H. On that prochamber, I am asuming that the sqaure portion of it is completely open, unlike an H, there is a ton more room for the gases to combine.....wouldn't this make even a deeper sound than an H, I assume this is your logic here.

 

Thats my point.. Hows it gonna sound when all the exhaust is dumped into a chamber, and must fight to get out? As opposed to kind of having a set path in which to go.. The H and X provide a set path.. The ProChamber dumps it all into a confined area.. The exhaust must find a path, left or right in which to take.. But not before its bounced off the walls several times and mixed up with all the other gases.. So it should sound pretty good..

 

Cool!!! I can't wait to hear how it turns out. You got an ETA yet on the part? We are gonna owe you for this, no one has tried putting the prochamber on the new 6's yet, at least no one posting that I have seen.

 

I can't wait for this. It should sound real nice, and be an efficient system. The Prochambers purpose is basically a hybrid of X & H, so it's perfect especially if you want efficiency of an X with the tone of an H.

 

The unit should be sent on ground shipping.. So once its here, I'll go have it put on..

@ManEHawk

Thats true.. I am curious how this is going to sound.. Hopefully a deep rumble @ idle, and a much deeper upper rpm tone.. This is all I need.. Based on the design of the prochamber, the sound should maintain at much higher rpms, based on more gas being in the chamber, with the same size exits.. My theory is, at higher rpm it should get slightly deeper in tone, as opposed to tapering off.. With more gases inside of the same size chamber, without increasing the exit size, the gases will be hotter and as the pulse exite the chamber, the frequency should be alittle tighter and deeper..

What we are hoping for is a sound similar to a 5.0L V8 from the year 1987.. If I could somehow capture this, we can consider this test a true success, and advise all 05+ V6 owners to make the $229 dollar investment into the ProChamber as the foundation of all dual exhaust systems for the V6 Mustangs...

 

If it works, MAC should pay you for establishing this standard for generating a V8 sound for the 6's.

 

LOL!! Well, being that the car already souds like a V8, and I am pleased with it, this can only make it more pronounced..

I am really anxious to hear it for myself.. I know its got to sound good.. We'll see..

 

3 years in ATL or one of the surrounding counties near to ATL / "metro" Atlanta. No such thing if you live in rural Georgia/no-wheres near ATL.

 

My Pro-Chamber, based on the tracking number is due to arrive on Dec 5th.. The info shows some type of rescheduling for delivery date.. May have to do with the weather back east.. At any rate, its not here yet...
