So I was flipping through an 928 book by CP press, looks to be out of the UK circa 2015.
I came across some engine pics of a track 928, late model, perhaps GTS.
Looks to be a custom intake build, with a configuration I've not seen before.
Anybody familiar with this? More info and how did it do?

 

Darn, it looks like I have been and am spending way too much time on my lower profile intake for my Custom 928 project.

 

looks to be a boxed ITB set up

 

I was pooping as I looked at the book Jake, forgot to include that.


Ok, I googled ITB.
Found this as an example:

I'm fuzzy on how the air gets to the throttle body.
Are the tubes just off in the picture?
What's the benefit of the fabrication?

I'm done pooping but still intrigued...

 

box is around it.. :-)

 

Is that a restrictor plate engine? ;-)
