under a bonnet the ITB suck hot air and every 1 deg C is a loss of 1 rwkw. They must be protected like on the Australian V8 Supercars to beat a nomral manifold with a over radiator cold air intake system.
Now here's what I would like to see match the itb to the harmonics of the air bouncing off the valve when it closes so that it doesn't try an bounce back multiple times by making the velocity stack taller and see if we can crest it over 500 or maybe that + make the diameter of the stack slightly smaller to increase the port velocity through the stack. Now some may say no because a restriction is a restriction an ultimately you would be making the breathing holes smaller. Buuuut being itb you have generally 45mm tbs and 8 at that so is it really a restriction? Next if you had 8 itbs (v8 duh🫣) an they were 10mm each would that not be comparable to a single 80mm? If that's true does it work with larger numbers an not be bc multiples of 10 just work ezr. Are 8 45mm the same or close to as 360mm( I would assume not) an if this be true why is it you can over carb a engine but not over tb it lol?

I honestly don't even care about the power. The ITB's win on sound alone. Unbelievable music. (I mean, the power is a nice bonus though...)
ITBs, X pipe and a mild cam is the dream for a street vehicle
If you notice we’re it makes power mild cam would be better with stock intake a 7500+ rpm cam individual throttle body’s benefit
Great Test And Comparison!
custom ls3? thought ls3's were 6.2l? ls2 is 6.0. doesnt matter just wanted to make sure what engine you used since i have a 6.0 and 6.2. thanks
You can hear those babies doing the magic on the top and and its still asking for more haha 😍
What brand were the ITBs you used?

Excellent work, guys! How do you get air to the ITBs in an application like this? Where's the inlet and filter(s), etc.?
The inlets are the openings on top. They have a small filter inside out a sock type filter.
Very interesting
Itb for the win

What EFI are u guys recommending with the ITBS?
The ls3 intake is a good intake
What cam?
