Has anyone done the V8 conversion kit from speedtweaks. V8 TB 48mm, on a 2001 V6, I think that mine has a 42, or a 46mm not sure. But if anyone has, please reply and let me know how it worked out for you (performance wise). Oh and another thing, also if somebody has done the 50mm billet please reply, I'am just debating on which one to choose from.
Thanking you in advance

Nate,
I have been tossing around the idea of changing my v6 TB. Originally, I wanted to do the swap v6 to V8 TB with a speedtweaks cable. I bought the cable but waited about the bigger TB. I had several issues, more performance (flometrics 48mm, more $s)or a little less power (2 hp, 10 ft/lbs) with factory v8 and save money. I read that emissions would not be affected. Swingman installed a factory v8 TB and loves it. (read older thread "V8 TB & Emission Testing") Lesley and BigG are planning to to the v6 to v8 TB swap. I'm starting to lean towards the flometrics billet 48mm TB. I have been saving for it and Speedtweaks will have a "Promotional Pricing" in Dec. I know its expensive but I seem to like the design of the billet version. I heard not to go above 48mm unless some serious mods have been done to the v6(supercharger). I hope some of this is helpful.

Harvey,
You can use the Flometrics 48mm TB but would recommend a good intake system, exhaust system, and headers. But you can run the 48mm Flometrics on a stock V6...that's what it's designed for.

For all you older dak owners out there(92-96), I replaced my 6 thrl body with an 8 appl. I also ported and polished it. stock cfm 678, after mods 776cfm!! I know all you are probely saying goodby bottem end, but I am happly to report that the power band got very wide.1800-5000rpm, much more over all torqe. I also just installed that new helix spacer, WELL WORTH THE MONEY!!
If any one out there is going to do any mods to there early daks,give me an E-mail cause, I have done A LOT of performance mods to my roadracing,mustwat eating DAKOTA!!!

Polishing the TB does absolutely nothing Manny. (Flometrics and several other TB builders have proved this.)
What bore size and where did you flowbench test the TB at?

As in polishing the thrl body, I did not take a seperate measurement when I polished it. I based lined it first, made all the mods and put it back on the flow bench.
One thing that I did do seperate was to do an individual test with the air cleaner stud and small plate on the trl body and off of it. it made 46cfm more with that thing off.
As in to where I flow bench tested it,I was on a superflow at REBELLO RACING in Pachaco, cal.. I used to work there.

Removing the plate is an easy (and old) modification....you want the specs for the "S-Bolt"?

On the Helix spacer...they're a bunch of "Hocus Pocus". We've dyno and track tested them on several different models...NO GAINS. Even have a statement from Airaid on them. The reason they don't work on the Magnum 3.9/5.2/5.9L is due to the design of the intake manifold. Save your money.
Got a picture of the TB?

Manny, i'm curious to see how you got 776CFM from a "ported and polished" stock TB. What excatly did you do to the bores? Reason being is that the stock V8 TB flows 635CFM @ 25"hg.

hay guys I take your word on the spacer but as long as I have been working on my truck and other trucks for freinds, there is one thing I will say that I know you can atest to is, that there is know to engines that are alike.
I use my truck for an example cause like I said I have done A LOT of mods to it.
The reason I say that it does work is because in mid october I was running my truck at thunder hill raceway in the city of willows, and there was a off duty CHP running his mustang in one of the more faster groups. He kindly decided to borrow one of the radar guns that he uses to bust people with.
So I asked him if he would clock me down th front stretch. 101mph without the spacer, 105with. Wes I will admit when I put it on I had my doubts also,but I had to find out for my self.

to answer your question, first air cleaner stud and plate, remove air horns, modify shaft to have only one half holding butterfy, trim that half to only .125, use button head screws , thin out butterfly by .30, and open up that ridge just at the entrance by .20. I hope that you don't think I am blowing smoke, but the only reason I am putting al this info on this site is, so all the fellow dak owners can go out and smoke all these dorks in there stangs and rice crapers.

Manny,
With all due respect, without opening up the bores (which requires replacing the throttle plates with larger ones), the CFM won't change 98CFM. A factory TB only flows 635CFM @ 25"hg with a modified V8 TB flowing 710CFM and a 50mm flowing 790CFM. (Without the factory airhat stud/plate.) You can get the factory V8 TB to flow close to 700CFM with the mods you described but not 750+ without bore enlargement.
On the spacer, the reason they don't work with the factory manifold is due to the large plenum area and a tight, 90 degree turn and then another 45 degree turn into the runners on the V6/V8 manifolds. (The V8 manifolds are even worse as some don't even have the plenum divider anymore and the swirl effect is lost. They do work on the 4.7L as the intake design uses a seperate runner without the restrictions like the standard Magnum intake manifolds.
Here's the direct quote from Airaid on the Helix-Bore spacer:

Dear Sir, thank you for your inquiry in our products. The spacer makes no HP on the Dyno. It makes all of it's power in torque in the low end. If you haven't noticed any power on the Dyno or the track then it's doing what it's supposed to. You would not see any gains down the 1/4 mile or increases on the Dyno. The idea of the spacer is to improve overall drivability and fuel mileage. In most cases when people install a bolt on part they expect better mileage and power, what happens is they are into the throttle a lot more than before trying to test performance and that's when the decrease in mileage happens.
Sincerely,
Hope that clears somethings up.
