Thats like saying they could have put a better intake on there or even a more free flowing exhaust. They cant cause they have to stick to certain standards. Im sure if they could have they would have slapped a begger displacement engine in there, but that would change the classing of the car. (Isnt there some kinda tax overseas based on your engine displacement?)
Thing is, on horsepower freak builds people tend to swap to a bigger TB to get rid of the bottle neck. Same principle as removing the cat to get better flowing exhaust.
The more air and fuel you can get in and exhaust out, the more eficient your setup will be and make some kind of power!

LOL!!!
Where do you come up with this stuff?!! This is funny ****! My dad's *** jar? Who's dad keeps a *** jar!?! BTW, the gay reference didn't actually mean that you were seriously gay...it was simply a miata reference. I'm not sure how you missed that one with your huge intelligence, but maybe next time you'll get it!

Posts like this are literally dragging the quality of this forum down.
Tell me more about the 4-cylinder 4-stroke motor that is filling all 4 cylinders with air at the same time.
ONE cylinder fills at a time. You are filling ONE cylinder through a 60mm hole - assuming your ports and runners aren't more restrictive (they are).
Your geometry teacher would like to have a word with you. 40mm diameter x 4 does not equal 160mm diameter.

If you have ITBs that are 40mm, thats 160mm feeding the engine divided by 4. so technically you have the ability to feed more air into the engine and with short straight runners you get that supply faster.

An engine is basically a vacuum pump...so why are those numbers wrong? 40mm per cylinder, 1 complete engine cycle. What am I missing?

I knows how a engine works. It sucks in fuel and air, it compresses it, then spark and combustion which pushes the piston back down and the process reapeats.
I was just giving general numbers describe the differance between drawing air from a plenum (that fills with air through a TB) and drawing air from an open source (that get pulled through 4 individual TBs).
fact of the matter is you net gains from a ITB setup wont be much more than what you can get from IHE. It just more exspensive, better throttle response and sounds cool.
Isnt one of the keys to making power better flow?

See what I mean?
1) How would he know i have a boyfriend? (His next response will be something like "cause you're gay".)
2) How would he know if my boyfriend's dick would be on fire unless it was in his mouth after he ignited a shot of Bacardi 151?
3) Quit while you're ahead...oh wait...you'll never be ahead of me, **** Face.

Wait...he's right. It doesn't equal 160mm, but then again a 60mm throttle body on a stock intake won't equal 360mm per cycle either. So Wonton, your point is valid...math is wrong.

I think what WonTon means is...if a single stock throttle body is flowing 60mm it will disperse that much air over all 4 cylinders. However, if each cylinder is getting a 40mm throttle body, it will flow much more air per cylinder.
