 Subject: 4.7 70mm Throttle Body IS IN!!

Message:
If anyone would like to see the new throttle body for the 4.7 feel free to go to this link http://tobysmith.50megs.com/photo.html
This site is the quickest way I could put the pics on the site. Haven't had a lot of time to test it out though. The intake had to be modified as well. It will be painted with Black Heat Paint. This was a spur of the moment mod as the truck is needed to get to work. Sounds GREAT!! Let me know if you have any ?'s on the install. I will be working on an instruction booklet if anyone needs one. Hope you like it as much as I do.

hey smittyt2, what year is your dak? I heard that the 2001's had a 68mm TB and the earlier ones had a 65mm TB? Just wondering cause i want to do the TB upgrade but don't wanna play that much for 2mm. But then again I don't know anyone that has done the upgrade for the 2001 with the 70mm yet.

Answers to the ?'s
1.) Yes it is a 2001 4.7 QC. You will notice a difference in sound and power. Seems like it took a few miles for the PCM to give me my power back in the low end but it is back now with a little more I think. I am going off of the sheer feel of it. No dyno numbers.
2.) No I don't have a Baker hose I guess. If you are referring to the blue peice in the very first picture, it is some sort of adapter that comes with the TB. I am glad it came as well because it breaks the size of the opening of the TB down to about a 3 inch pipe which fits very snugly. I got some pipe clamps to make sure the seal was there. A 90 degree elbow and @6 inch peice of PVC and I was done.

I'm 99.9% sure that is the infamous "Baker Hose". It's made by Baker Precision out of California. They make all kinds of hoses like that. I'm betting the outside kinda sorta looks like it was wrapped with colored vinyl tape to give it the color huh? It's not taped, just kinda looks like that with ridges.
This piece was originally designed for LS1 F-Bodies. Oddly enough, I just finished installing this exact piece, color and all, on my '99 30th Anniversary Trans Am, came inside and read this post. It's a 3.5" to 3" re-inforced silicone adapter. The thing I don't understand is that the new tb seems to have a blade that is MUCH larger than the stocker. In fact, it looks larger than 3", so why would you want to reduce the intake down to 3", you would be wasting a large portion of the new tb?? I mean, if the original blade is 3", and the intake is 3", then why would going to a 3.5" blade with a 3" intake help anything? These aren't the correct #'s mind you, just using them for comparision. I'm sure this new TB does help, but see what I'm saying? Looks like some of that blade area is being wasted by using the "stock" 3" intake??

I was thinkin the same thing. Why get a bigger
throttle body with a bigger opening then down
size the intake pipe?? It seems you would
have the same thing you started with.

You got to start somewhere. I have noticed an increase in my power as well. I will be able to tell more tomorrow if it isn't raining. Wheels are just spinning on the wet pavement. If that is the case then who makes after market intakes that are larger than the 3? Could be interesting to test. I am definitely not a mechanic by no means. Any suggestions would help me a lot. Could you tell me if the 70mm is the size of the blade? What is that actual measurement for? I will have to compare the blades again. I think the picture is a little misleading due to shadows and such. The opening is significantly larger though. If I can find a 3 1/2 coupler and elbows w/pipe I will try the bigger intake and post the findings.

well, the new tb obviously makes better use of the available opening. the blade is siginificantly larger. I'm thinking the 70mm is the overall dimension, but the design of the new one allows the actual blade opening to take up MUCH more of the available space. What I'm saying is that a tb with the same size as the stock piece, would have a much larger blade, simply because it's designed to use more of the opening, instead of just having an "offset" blade area, it takes up 95% of the entire TB opening, which is cool.
I know that the original tb blad is significantly smaller than 3", and this one seems to be near 3.5", so a gain should be seen. However, I think that this new tb could be much better served, and reach it's potential easier, with a 3.5" or even 4" intake. Not sure if the 4" will fit under the hood though, it very well might.
as for someone that makes one, hmmm, not sure. I made a homemade setup similar to yours, but I went all the way with a cone filter and all, which is what i'd HIGHLY recommend for you. I saw gains with just that setup. I'd try to sneak in 4" worth of intake if I were you. you can get a fernco 4" coupler to replace that blue Baker hose at home depot. unless you live in Canada or Florida apparently. don't ask, I don't know why.

Go to SpeedTweaks to see the new 4" diameter Z-Tube. It's under the 4.7L Performance Package link. That'll get rid of the restriction!

Thanks for the info. I will definitely try the 3 1/2 or 4 inch setup. I don't know if you can see in the picture but I do have an Airraid intake filter on there. I will more than likely break down with the K & N FIPK when they come out with it. If they do come out with it. "Should be right around the corner." Right, right, right. Well, then I would have the same problem I am having now. I guess homemade or the z'tube from speedtweaks it is. I will let you guys know if I notice any differences.

G-Forced is currently testing a 3" true cold air intake for the 4.7. After the testing is complete, a 4" version will be released for the new throttle body. If anyone wants more information, email me.

cyberwolf, correct me if im wrong, but wouldnt the metal tube on the g-force intake heat up the cold air? it would be like an oven. i thought thats why K&N uses a plastic tube for their cold air kits. no doubt the g-force looks cool though

The K&N inatake actually has a lot of problems with their plastic tube. They are also aware of the problems. They are very well known for cracking. The good part is that K&N will replace them for you for free. Bad part is that they still keep cracking. For those of you that have one on the 3.9, 5.2, or 5.9 look at the lower driver side of the air hat. There is a very good chance that is could be cracked. We actually looked into making it out of plastic. It would be much cheaper but there are durablity problems with it. The G-Forced tube is made out of aluminum. The prototype in the picture is made out of stainless steel. I have had it on my truck now for 2 weeks. I am constantly popping my hood to show people. Believe it or not it doesn't get very hot. Regardless of how hot the tube gets, the air comes from outside the engine compartment which is at ambient temperature. On the other systems the air is coming from inside the engine compartment where the air is already hot. The air flows through so fast that it doesn't have much of a chance to get hot. Also, they will be offered with a powder coat or ceramic coat. If you are really worried about it, go to Home Depot and buy some insulated duct tape.
Thanks,
Keith

ok that makes scence. two more questions.
1) i know there is a "ram air" kit for the 5.2, 5.9. but is there a "cold air" kit for them as well? (like the one you have on your 4.7)
2) Is g-forced comming out with a "ram air" kit for the 4.7?

1) For the 5.2 & 5.9 we have 2 version of the ram air; dual ram & single ram. All the single ram does is eliminate the duct on the driver side. They are both cold air kits with a ram effect.
2) In the future we plan on offering a ram air box that will adapt to the existing cold air tube. We will begin working on that as soon as we get the 3" and 4" cold air running smoothly in production.
Thanks,
Keith

Regarding the message from smittyt2...what is the blade he talks about. Iam about to take off my stock 68mm TB ('o1 Dak) and remove the so-called lip inside it, to make it a true 68mm and I don't know what I'm in for. What is this blade that he talks about...does he mean the butterfly valve plate?

Yes, that's the blade. If you F that throttlebody up and take out too much material, be prepared to drop about $250-$300 on a new one. Or you could drop $400 on a new 70mm TB from www.speedtweaks.com
Good luck.

I"ve self proted My TB on my 01 4.7 QC 5spd.
Stock is a 68mm. I removed the lip at the bottom, and some of the taper at the edges, works great!
To get the cables off, just rotate and unsnap, after you take the TB loose. Don't force it!

Just remember, the 4.7L has a nasty resonance in the intake manifold. (Notice the resonation chamber in the airhat - that's quite a bit to keep the noise down.)
The 4" Z-Tube's do work well.
