why are these better and why do they cost so damn much?
I really don't to much about them. what kinda gains are we talking about. are other mod's needed if you get these?

 

q-tiger can answer your question.

 

Good for NA.

 

what happens to the fuel rail? is this something that should be last if your building a NA motor???

 

It allows you to flow as much air as possible. I have a grand total of 200 mm of throttle body on my manifold. Makes a great deal of difference when upgrading from what... 60? 62? Keep in mind as well that unlike an enormous single throttle body, intake air velocity isn't dropped as much, since you just have a straight runner down to the intake port.

In addition, each cylinder recieves an equal portion of the airflow... there's no intake manifold that may for example bias cylinder three (in the case of many Hondas) or the like. I can tune each throttle plate individually to gain any results I want, in addition to modifying all the plates at once.

There's still a fuel rail with injectors. I can take some move pictures for you if you would like, but that's the fuel rail right below my knee.

I'm doing it first because I'd rather not waste my money on injectors, rail, FPR, skunk2 manifold, and an oversized TB when I can get all of those in a package deal with MUCH better results for not too much more money.

 

What about all the sensors?

 

do you leave them like that all the time? or are there filters?

 

that is what i would liek to know also , this seems like a GREAT investment, but what abotu protecting it from sucking somethign in there..??

 

there is one large filter that covers all the throttle bodys, kinda like the filter on a blower for old muscle cars.

 

Silly question maybe, but what about the TPS? Does this have to modified?
