Idea for throttle body

[Grr]

I am going to try something over the winter and wanted some input. I am going to get rid of this stupid twin barrel TB and switch to a single, LSx style TB.
In doing this, I also plan to substantially increase plenum volume. I am going to make an aluminum elbow much like the vortech, and welding a flange to it, to bolt to the intake. Then running this out about 6" to the side and attaching the TB. I havent calculated out how much volume this will gain, as im not sure how long this will be. Any thoughts on this? I feel at the moment my stock TB (unported) is costing me 2-3psi. I figured some of you may want to see how this works, so i thought i would just try it.
The other option is making my stock TB into a monoblade that i already have designed.

Wouldn't this be a much easier solution :

A buddy of mine is using a monoblade from arizona speed on his D1SC setup. He has done extensive research on his setup and he decided that this would be the best. His name on here is T/Akid give him a hollar and see if he can help you out.

I dont think the t/b is costing you that much. You have to remember that the more effcient x amount of air going into the motor the less boost your going to see. In other words your going to see less boost as a restriction but gain more hp as a end result. Does that make sense?, I know what im trying to say just a little hard to explain. I'll break it down a little more if you dont understand.;)

This is true... my buddy added cams to his mustang and because he was flowing more air with them he made less boost but gained power

It makes perfect sense. People always mis-understand what the boost gauge is actually telling them.

10lbs of boost means 10 extra lbs of pressure in the intake manifold NOT GETTING INTO the motor. 30lbs of boost means THERE IS A SHITLOAD OF PRESSURE BUILDING UP INSIDE THE INTAKE because it's bottlenecked and has nowhere to go.

If your car has 10lbs of boost right now, then you go and put a set of huge AFR heads on it, with a ported intake, and a big TB, it will only make about 3-4lbs when you are done, but it will make a shitload of more power.

No you guys arent really understanding what im saying. The intake is getting up to around 12psi, but the pipe before the TB is probably closer to 15psi. In fact, i removed the pipe completely the other day and ran without the blower. N/A, at 6k rpm i had just over 5" of vacuum. No one can tell me that the TB isnt costing me some serious airflow, and therefore less boost in the intake.

I see what you are saying. Yeah I guess it is somewhat of a restiction if there is a 3lb difference.

But what you need to determine is the total amount of airflow that each can support. A twin 58mm TB might be neck and neck with a 90mm single. I haven't done the math or anything, but it is just simple math to check. You just have to figure which one has the largest surface area.

I could have sworn that a stock 48mm one will flow around 750cfm, which is sufficient for most N/A motors, not boosted ones though.

Well on my 6.0L lsx, i was using a unported stock TB. I pushed 14psi through that with no problem. One of the things i was looking to adress with this is the lack plenum volume on the LTx, i think that would really help with the bottom end and mid range TQ.

DOOO IT! only problem i for see is the throttle cable and maybe some sensors but all in all i bet it would be easy so long as you can TIG alum. decent and machine a flange . i want to see this and would be willing to mill you some plates if you want to make me one :)
