LS ITB's
Itb 
Yes similar... and you can see they have tried to make the plenums as large as possible while still packaging neatly within a confined space. I would love to see them with the covers removed from the plenums.
As already discussed, the main benefits of ITBs on a race car is the throttle response/control. The power is limited by the restrictors.

I've also got to send in a quote request form to Hogans!

I guess it is in the eye of the beholder....
this is a lot of work if you spend alot of time an a tig welder and all the cutting and fitting to get it right is hard work .
Mad props to the guys that made this

I've posted this before.
He made 65 HP more using the ITB intake over his Wilson sheet metal intake. Couldn't get the Wilson to idle less than 1,200, the ITB idles smooth at 600 rpm. Its an LSX 454ci., 13.5 E85 fuel, 650lift 260 duration @50 on a 114ls on 1.7 ratio, AFR 245cc heads.....and if you contact him, he's a member here too....thats 752 RWHP.

That's the thing. He doesn't have experience with ITB's. He says knows people that do. He thinks they are the magic bullet that will make any motor make more power and that everybody should run them. They are rpm limited just like anything else. Will they make more power over a larger rpm range than any other intake setup? You bet. Are they great? You bet. ARe they great for everyone?? Not hardly. Will they make more power from 7k to 8k than a GOOD sheetmetal?? No.
I agree with your last statement plus the fact that packaging any kind of filtration system for a F-body/vette that won't kill power is a whole new world of problems.

To sum it up, is an air-box NECESSARY to run the ITB intake? That GTM, idling at 600rpms, wasn't using the air-boxes.
Also, DBW wise, I saw a kinsler on a C6 Z06 (MTI-racing mile car 206mph N/A) with what looked like a stock TB, chopped and the motor was "tapped" into the arm mechanism to articulate the TB blades.
What about filtration without an airbox? Anything thick enough to protect the motor without having to slip a few pairs of nike no-shows over the snorkels?!

Anything you slip on the end of those trumpets will kill power. There's alot that goes into setting these things up and running them and if your not willing to put in the time and effort don't bother.
Interesting..... Got this today.

I have a few extra harrops in stock here, that i am not using. Ive had alot of fun with the ones we put on. They are all Electric throttle units. I think i have one 58mm and one 52mm. They do have provisions though for a cable under the cover.
That is my gtm in the vid. There are more of it running and i think dyno runs on youtube i think. We have beaten that car up from day one. The motor has definatly earned is money in fun.
The 224 afr where modified to match my Edlebrock 245s from lingenfelter. They worked pretty good before i pulled them off to run a set of ls3 style heads. I didnt gain much after the head swap. Kinda wish i would have left them on. As im only at 740 hp on the last dyno pull last month, Gained a little torque though with the ls3 style.
Tuning for the itb fly by wire was pretty easy once you figure out all the limitations on throttle openings and airflow needs.. Then you can make it smooth as silk and very easy to drive. Without changing the throttle progression tables, the cars are very hard to drive as they just want to take off!
