Here are some videos I've posted before.
242/242 106 LSA 106 ICL in 346 with ITB setup that Sam of Sam's Performance in Sydney fabricated. Sam also tuned this car in SD. Keep in mind this was a few years ago before the Harrop hit the mainstream.

how much boost can the Harrop take? particulary the black part, cause im assuming the ITB part can take pretty much anything pushed through. im having very interesting ideas of a Warhawk LS7 block, LS7X heads, ITB intake(probably Harrop) being boosted by twin Rotrex superchargers, with a nice direct port nitrous setup. all the best newest parts coming to the LSX market.

Even the guy at Harrop talked about how much they killed the power. I ordered mine with no air box and no plate that holds the air box. After I check fitment in the F-body chasis, I'll work on filtering the air. Here's a pic of it without the rif-raf.
The second thing would be to get rid of the parts store fuel line. Common, worm clamps? Fix that!

My ITB's bores are straight, but the velocity stacks are at least tapered (My stacks bolt-on, so i can switch to longer/shorter as well).
Good job on the fuel lines. Some nice stainless braided AN line would look awesome. Also, nice intake. Be proud to show that off. Make the install look good, and put up some pics!
It has a -8an stainless feed, -8an stainless crossover and a -6an stainless return w/aeromotive regulator. The lines that are on in the pic came on the intake from Harrop. There set-up to plug n play with the stock fuel lines.

It is for a modified Honda and not an LSx, nevertheless it shows the way. An ITB without throttle valves inside, for extreme flow capacity.
The intake valves do the throttling.
The engine works from 300 rpm to 9000 rpm.
More cheap than anything known (zero cost).
Initially the original plenum was left untouched, only the throttle valve was thrown away:
Then the plenum was sliced to result an efficient ITB
And removing the air filter
Just after cutting
Applying the pushrod VVA on an LSx engine, see relevant thread, a cheap trumpet set can easily overflow any ITB.
