explain the additional injectors for an ITB noob. For NAWSS?

Same as motorcyles, the fuel injectors high up in the intake tract come online at high RPM. The longer distance supposedly gives the fuel more time to atomize more completely and thus burn better.

Holy shit, that top fuel cylinder looks like a horse is pissing in it.

They have horse cock injectors!

ITBs + twin-cam motor = uber sexy time

If I only knew enough about engines to know what to do with it. Is it bad that I just want them because they just look awesome?

I've heard its a nightmare to tune for itb's, can anyone comment on this?

**Adrian_Visser** · 03-24-2009, 06:28 PM

unless you have some sort of plenum that the itb's are drawing air from (like on s54's or euro s50/2's) which you can put an afm on the inlet of you have to run alpha n fuel mapping, so yah more complicated to tune i'd say, afaik apha N is pretty finnicky to mess around with.

you guys should check out the rest of the videos that guy has, seeing inside a cylinder during the strokes is pretty cool, and check out the future of valve technology, no springs!!

Plenty of other options for fuel management, and no they aren't that difficult to tune if you are familiar with it.
