Can someone explain the point Individual Throttle Bodies?

Moah powaaaa.

No but seriously they use them for better revving and a bit more power

>>16647881
why can't you?

instead of drawing air from a common chamber (plenum) which can restrict airflow at high airflow rates, they draw directly from the atmosphere.

Depending on trumpet length, you can either have lower end torque gains (mid-speed airflow) or shorter trumpets for high revving goodness.

Also when done properly all of the cylinders get (basically) even air distribution. A lot of the earlier VQ35 stock intake manifolds would not deliver enough to the front 2 banks when people started throwing mods at them increasing the airflow demands on each cylinder

>>16647867
More Bwah.

>>16647914
how much gains would you say you'd get? a significant amount?

That's outside of my area of expertise.

All I know is they're a pain to own in a DD. Since theres no common plenum, sourcing vacuum is a pain, getting a decent "MAP" signal is retarded, gotta get rid of MAF if the car is equipped. Gotta get those bitches tuned regularly as they're very sensitive to weather changes.

But I mean, M3 E46, 4AGE 20V's, are a few examples off the top of my head that had factory ITB's, so they're obviously not just a meme.

>>16647867
ITBs are designed to let your expensive engine suck up rocks, dust, sand and wear the shit out of the motor you just finished building.

a lot of guys who run big ass velocity stack-type intakes on plenum equipped vehicles also run without an air filter at a car show, do those guys count too?

Also forgot, E39 M5's have ITB's with medusa looking trumpets fed from a "plenum" style intake

sick.

also, not multiple throttle bodies.

Better throttle response and less restriction. Also idk why nobody in this thread seems to know, but you can use an air filter and a MAF with them.

Yeah literally anyone "going to ITB" is never going to do more than strap a screen to the trumpet, maybe a Shop Vac piece of foam if they're lucky. That's just the general state of tuning these days; monkey-see monkey-do. Silicon dust, salt and other abrasives is no joke.

whoops yeah you're right

>>16647948
The main gainz are throttle response and per cylinder tunability which is useless if you can't tune by cylinder. ITBs are not magical power making goodness.

>>16654397
The point I'm making is that individual throttle bodies and an open intake is orthogonal. You can have a traditional plenum and airbox design that also has MAFs with ITBs.
