3.5" TB and spacer
well if the polished one come exactly 100% like in the picture im down for that one.. i just love the weld.. and while you tag you intake ..?
publicity..?
i just hate having something on my car and its a no-name.. lol

Are you saying you DO or DO NOT want a Rebel Auto Worxs decal on the intake?
If results can be posted I too would be all over this. I do have one question though, I have a K&N cai and does anyone know as of yet if all I would need to do is get a larger diamitter coupler and maybe trim it or would this Spacer/TB mod make my K&N useless. I dont want to start buy mods to only find out down the road that Im gonna have to change other things just to get them to work. That is a waist of money.
I know everyone wants everything over night, but it doesn't work that way.
Here's the game plan, we're going to make the spacers first. I've booked in some time on our CNC.
Next we are going to test the spacer on a GM Stage 2 with our intake. We cannot go and test for every intake that's out there. For fitment, we used a 3" coupler and got it to fit over the 3.5" TB after some stretching. I would recommend buying one of these along with your TB:

The coupler on the injen is fairly stretchy since it's all rubber with no reinforcement, so I would say it will go over it. I can test this one out.
We will not be selling any spacers yet because they are not made and also I'm not going to take anyones money until the gains are proven.
Not 100% sure why the boost went up, but you can look at the log files posted yourself. The only theory I can come up with is that the SC is starving with a 2.7" pulley on the intake side, so with a larger TB, it now can compress more air. We will look at this again when we have the GM stage 2 with the bigger throttle on the dyno.

Is the opening on the intake of the twinscrew kit machined out big enough for the throttlebody to be a direct fit? Seems to make sense that it come that way to save your TS'ers from having to mount extra pieces.
It also eliminates another chokepoint that is still there if the smallest part of the intake is not ported to match.

till Oct 11th, give everyone a chance to get in on it
we have to take a look at this as it was not originally designed for it.
2 weeks, gives everyone time to get their TB's aswell
BTW, just finished tweaking Distillion's car a bit more, he now hits 112mph in 3rd,

So I guess now the waiting game begins. I can say this, when I had my SRT4 I purchased a bored TB. It was only bored to a specific percent larger then the stock due to the srt4's intake plenum only able to consume so much air. And with there TB I saw my boost increase ( I want to say) about 2-3psi. I know there were other companys out there that were selling TB's bored on the excess side and ppl were actualy seeing a decrease in performance. So i guess my question in all this is, do we (you) know just what percent increase in TB size in efficient for our SC's.
no problem

Please just log the MAP1 (before SC) at WOT (before and after the new TB) with one of your 3" intake. You'll see if the stock TB is restrictive !
Personnaly, now with a 2.9" pulley (boosting only 12 PSI at Alberta altitude), stock intake with a K&N air flow filter, I get only 0.2 - 0.4 PSI max of restriction from the stock TB, stock intake and high flow filter.
Also, I can remember at see level with a 2.6" pulley boosting around 19 PSI, I was seeing 1,5 PSI restriction with the stock intake and stock filter.

Colorado's came in a 2.8L or 3.5L (I4 or I5) from 2004 to 2006, and the 2007's are 2.9L or 3.7L.
I know when I had mine and it was opeded up from (I belive) 53mm to 55mm. I noticed a huge increase in throttle responce, just like what was posted on here earlier. You touch the gas and the car launched forward. You had to learn how to drive the car all over again.
I also just thought of this, recenly when I had a 07 Stang GT with a bunch of mods done to it including a BBK twin 62mm TB, it as mentioned above increased responce but not a single hp increase on the dyno. We dynoed the stang with it on and with the stocker on and saw NO increase in hp at all.
Im not doubting your work and the fact that the 3" tb will increase responce, but as for an increase in hp, from what I have read and seen on dyno's the tb is not the week link in the chain. Most stock units can support what is thrown at them.
Im still interested in some solid data to see just how the Balt responds to the tb and spacer.
