ITBS + plenum + turbo = worthwhile gain?

4 tiny turbos would take just as long as one turbo 4 times as big ... well actually i think it would be worse due to the way the exhaust pulses would be hitting the turbines. Think about it, instead of 1800cc to power a turbo, now for each you have 450cc.
whatever, you were just joking anyway, and i ruined it lol.

i was thinking about doing twin turbos just for the awesome factor, where each one is on it's own system and is fed into two ITB runners. seems expensive, and twice as many points of failure. But it sure would be one engine bay packed to the gills with awesome.

I'm gonna toy around with the idea of using a mustang 5.0 MAF in my setup, it would instantly make tuning a snap. I don't really trust my current IAT sensor anyway, which is installed into the #1 runner, literally an inch and a half from the engine head.

idle would suffer with hybrid alpha n. off boost would be in alpha n while on boost would be in speed density.
ideally, i would like to tune idle in speed density, above 85 kpa in alpha n (which is how i have my itb setup) and boost in speed density. it doesnt seem doable that way. so, maf might be the best option with "boost sensing" for timing retard during boost.

ITB's are on my long term projects list.

well, i don't really care, I already have the ITB's. I'll just do it for the cool factor. It might flow better because the pressure is being regulated right at the runners, and it might also have better response. I really don't know though. What is certain though, is that it'd be beastly. As long as it performs as well as an aftermarket manifold I'll be happy.
