EFI Intake

[James Weiler]

This is of interest to me too, as I'm thinking about a custom intake as 
well.  The Jeff Hartman EFI book talks about this abit.  He says that the 
best way it to have a T'body feed into the side of the plemun at the 
middle.  Does that make sense?  Rather than putting the T'body at the 
front or back of the plenum.  If you have a look at a 5.0L mustang they 
have what he suggests, if you look at a chevy TPI they have what he 
doesn't suggest.
How did you decide on 80% for the plenum volume?

thanks
