Also, what determines the flow rate of the cat is the number of cells it has, more cells = better filter = less flow. I would bet the GT and V6 have a similar number of cells, so basically the flow restriction would just come from the fact that the GT cats are slightly larger in size?
Also, since the GT has 1 more cylinder per bank, it is possible there are MORE cells per cat on the GT to filter the extra emissions.
All in all i believe it is a sound idea in theory, just fails as far as application is concerned. Again though, i am mostly shooting from the hip here.
way ahead on this...you cut the flange on the GT CATS and treat them as you would resonators. essentially they are independent units. it shouldn't be too hard to get a shop to do this for you.

a good shop should be able to do all this for $100 or less...if they charge more chances are they want more money to do something they will be learning from.

For the cells within, Im banking on the idea that the GT CATs are larger and with more flow area would be less restrictive. Again i could be wrong but as we have seen with modifying the 3.7 it doesn't seam to follow the same set of rules that most cars do (i.e: intake, cat-back exhaust, larger TB, TB spacers...and so on)

So back to the subject... I fitted the gt tb and there is a quite noticeable difference in power. Even untuned. I do under stand it's hard to justify 400+ dollars for a couple ponies but for 100 or so, Some people can justify it.

I am capable now of machining gt tb to fit so I might offer the service but not sure if there's enough interest in it. Those who are get in touch with me.

Oh good. things sort of died on here once the OP dropped out. i think he had to deploy somewhere or he moved or both, Not sure. Thanks for the info. Im sure there are a few people who wouldn't mind going the GT TB route

If anyone needs a GT TB for their V6, I posted mine in the classifieds section. I never installed it.

The intake manifold opening behind the throttle body is 80mm wouldn't matching it be better

Some guy here on the forums is selling 80mm throttle bodies for v6 3.7 and he even shows pictures of the fitments and says it works

Just buy a GT TB off Ebay and do it yourself. I started from 0 and did mine in about 2 hours. It helps if you have a drill press but others on this thread have done it with just a drill. I'll send you instructions if you are interested. Let me know.

just wondering how you are seeing this power? Real dyno, time slips or Butt Dyno

just curiosity ain't trying to insult


Low, ya made me laugh (sorry Fintle)

From what i noticed when I put one on is that it will make your throttle just a tad bit more 'responsive'. Maybe a little bit smoother/quicker through rpms too. Nothing night and day but minor enough to notice. I'm guessing it will shine even further if you can port your IM, and use a tune required CAI.

LOL, no need to apologize to me. I've just been on harsh "no more bs" policy. I should tone it down seeing as a lot of these guys haven't seen the posts and threads I have which brings out this.
Low sorry about that. Earlier in the thread it was talked about as being very simple to do. I personally don't have the tool, garage or time to buy a GT throttle body and start drilling holes. I am much happier paying someone for taking the time for me.

I have a question. I'm on the verge of going on with this experiment. I'm looking to buy a 5.0 TB. But I want to know first if it will fit with a stock intake? And if anyone is willing to sell one with the bolts already re drilled I would appreciate it lol. Make everything a lot easier

Stock, not 100% but I would say you might need an aftermarket or something do use as an adapter.

Yeah you'll need a new rubber coupler. The stock one is tiny.

Back from deployment. Sorry for being gone. I have my entire intake system custom made to match now. I will post some pictures. The bored manifold opening, 80mm tb with the velocity stack and 3.5" intake tune shows great flow on my virtual dyno charts for airflow. And it looks great.

I recently purchased one of those Tb from the sledgehammer. They are drilled and look great. My club has A Dyno day in June at National Speed. I intend on checking it " only the Tb Bolt on" on a Dyno run alone...I'll get back to you..

Now if we can get some hard numbers to compare the 73mm bbk tb and the gt tb on the V6s...

If i did a gt tb, i would get the steeda intake and do a port and polish of the upper intake manifold. Those with a good exhaust and tune will definitely give the pony some giddy up.

Well does anyone have any suggestions on the best way to remove those plastic fins from the intake opening??? Do you think I can stuff it with a rag and grind them out on the car ??

Someone said Lone Wolf sold port and polished ones for about $400? Not sure if this is right.

As long as you dont get any shavings in the engine you should be ok i think.

Yea Thanks. That's sort of what I was thinking...Stuff it good and tight with a rag and grind them out. I would think it would be a pretty simple procedure. Just need to get rid of those fins so the butterfly can open all the way. Hope your having a good holiday weekend..

I wonder if shaving the fins themselves add for any better gains? Not sure how they work on airflow.

Me either. I guess they were put in there to supply a little strength at the bolt up flange.

You would think by eliminating them and making a smooth straight airway, you would/could see a benefit. Like replacing the stock intake tube with a smooth one without baffles. Idk, just my guess.

Question.. why wouldnt you just spend 1 dollar more and get a motorcraft 500s filter rather than a ****ty stp.

If I end up getting Lonewolf to port and polish an intake for me, I may very well try this mod out, I have an Airraid intake atm, but if the Steeda one increases power by that much, I can just sell my airraid, and pick up the steeda. Also who was the guy on here, you all were talking about, that was selling the tb's?

Last time I checked performance isn't measured by the brand of oil filter. Stp, k&n, motor craft, Mobil all have good oil filters. We motor craft and stp are mid grade. If I wanted the best I would put the best on it. Truth be told, as long as you change your oil and use a quality product it works just fine. If your going to bash a company or product then use facts not opinions.
